Hydrophilic Swelling Waterstop Joint Sealing Profile

Swellable Waterstop - SealBoss SwellTape

What are Hydrophilic Expandable Waterstops?


Understanding Hydrophilic Expandable Waterstops

Hydrophilic waterstop PROFILES and SEALANTS are used in construction joints in  commercial and residential below ground structures with a low to medium ground water pressure.

Applications include pipe and steel work penetrations through walls and floor slabs, connecting joints in diaphragm walls, construction joints in in-situ and precast concrete, cable ducts and more.

Hydrophilic expandable waterstops, also known as swelling rubber waterstops, are specifically designed to function as sealants that prevent moisture infiltration and water migration in to seal all types of joints and penetrations in concrete, including cold joints and construction joints. These waterstops possess the unique ability to expand by over 400% in volume when exposed to moisture, forming a flexible and watertight compression seal. 

Two Types – Profiles and Sealants

Hydrophilic swelling waterstop joint sealing products can be categorized into two types – Profiles and Sealants.

  • Profiles: Under the Profiles category, we offer SwellTape, a joint sealing profile that expands in volume while retaining its dimensional stability.
  • Sealants: The Sealants category features SwellCaulk, a one-part, moisture-curing polyurethane sealant featuring a balanced expansion rate and distinctive swelling properties.

Application: Expandable Waterstops for Cold Joints and Construction Joints

Cold joints and construction joints represent areas in concrete structures that are particularly susceptible to leaks and cracks due to water penetration. Unchecked water ingress can lead to a range of issues that compromise a structure’s integrity, including:

  • Rebar corrosion: Water infiltration can cause corrosion in the reinforcing steel, which may weaken the structure over time.
    Expansion cracks: Expansive forces resulting from water penetration can lead to the formation of cracks in the concrete
  • Frost and thaw cycle damages: Repeated cycles of freezing and thawing can cause deterioration in concrete structures, particularly in colder climates
  • Health hazards: Mold and fungus growth resulting from moisture infiltration can lead to adverse health effects for occupants.

By employing hydrophilic expandable waterstops in cold joints and construction joints, builders can mitigate these risks, ensuring the longevity and stability of concrete structures. 

SealBoss offers an assortment of hydrophilic waterstops that have demonstrated their quality and cost-efficiency in managing water containment issues. These products are suitable for a wide array of applications, whether the goal is to retain or prevent water ingress.

What is SealBoss SwellTape?

SwellTape is a water-activated swelling waterstop synthetic rubber strip used to stop water infiltration through cold joints (see definition below) and concrete construction joints.

Hydro-active SwellTape is an advanced, specially designed, non-bentonite swelling rubber product that reacts with water by gradually and consistently increasing its volume. This expansion is carefully controlled to prevent any potential damage or disruption to the surrounding area. To securely attach the tape to the substrate, it can be embedded in SealBoss SwellCaulk , which acts as an adhesive.

Hydrophilic Swelling Waterstops  – Tape Strips and Caulk Options

SealBoss offers a variety of high quality and cost effective hydrophilic waterstops which can be either applied in as tapes or strips, or as gun grade caulk using a caulking gun for a very quick install procedure.

SealBoss state-of-the-art have a proven track record for being a high quality and a cost effective solution.

SwellTape – Pressure Seal

While expanding, SealBoss SwellTape creates a pressure seal, thereby stopping the flow of water through the joint and creating a permanent seal. SwellCaulk can withstand high hydrostatic pressures when installed to specification.

What is a Cold Joint?

A cold joint is the area in the concrete operation, where fresh and existing concrete meet, creating a fine joint caused by a lack of bonding / cohesion of the old and new concrete.  The cold joint is created when the original batch of concrete has begun to set (or is fully cured) before the next fresh batch is added. The two batches do not form a strong  bond and create a  for water to migrate. 

SwellTape Applications

  • Water Stop and Leak-Seal Caulk for Cold Joints / Construction Joints
  • Retaining walls
  • Foundations
  • Slabs on Grade
  •  Tunnels and culverts
  • Dams, Canals
  • Pipe penetrations

SwellTape Application Advantages

  • Works on Smooth, Rough, Irregular Concrete Substrates
  • Horizontal & Vertical poured-in-place Concrete Joints
  • Expansion Delay Formula to allow Concrete Cure Prior to Expansion
  • Reliable and Durable
  • Retro-fit and New Construction
  • Can withstand high Hydrostatic Pressures

SealBoss R70 Pump Flush is our universal pump cleaner and conditioner to be used with all of the pumping equipment offered by SealBoss.

This product is a proprietary blend of lubricants and conditioners to be used as part of your cleaning process. Now, before we get into that, I just want to also introduce the five and the one gallon packaging based on whatever size jobs you guys may have.

So, back to the idea of being part of the cleaning process. It’s very simple. We have a vast array of pumps ranging from polyurethane injection pumps to structural epoxy injection pumps, and of course, our JointMaster Pro 2 joint fill pump that pumps polyurea in all cases, what you’re going to want to do is attack the cleaning process in two very easy but distinct steps.

And here they are:

Your first step is going to be to take a solvent. We recommend xylene here at seal boss and run that solvent through the machine so as to go ahead and Purge.

How do I know when I’m actually purged?

And the answer is very simple as you run your xylene through the machine.

When you see fresh or clear looking xylene coming out of the end of the manifold or the applicator of the pump that you’re actually cleaning. You’ve met the purge condition. It is at that point where the R70 comes into play.

What we’re going to do is take a small amount of Pump Flush , because when you think about the volume needed all, you’re really going to be doing with our 70 is running a small amount through the system behind that solvent flush — xylene flush — to get rid of any xylene that could be left in the system.

What’s the system?

The system is the pumping mechanism, any cylinders, any Pistons, the hose itself, the applicator, and the manifold. Once we chase any residual solvent xylene again is what we recommend out by using our R70 Pump Flush.

Now, we’re clean!

A couple more words on that. You can either store that unit if you know, for example, you’re not going to be doing any injection, you’re not going to be doing any joint filler for months on end. You can go ahead and store it, winterize it with R70 Pump Flush left in it.

You can also go ahead and be ready for the next days worth of shooting Either the urethanes, the epoxies, the polyurea, and what you’ll do is you’ll fill your tanks normal, and then you’ll just purge out any remaining our R70 with the product for that next live install that you have, and you’re ready to go.

R70 Pump Flush lubricates, conditions and preserves the key components of your machine for the long haul.

SealBoss offers a comprehensive selection of polymer dispensing equipment and accessories including professional injection and floor repair joint fill pumps, injection ports, hoses and applicators.

Sealing Tie Holes

Sealing Tie Holes

Sealing Tie Holes

Sealing Tie Holes a.k.a. Tie-Rod Holes in Concrete Structures

Introduction

Tie holes, also called tie-rod holes, are small openings in concrete structures created after removing tie rods used in formwork. While essential during construction, these holes can become problematic, especially when exposed to hydrostatic pressure, leading to leaks. A proven and reliable solution to this challenge is polyurethane polymer foam injection.

In this article, we dive into a real-world example of a contractor effectively sealing tie holes and addressing shrinkage cracks in water tanks for a rural water district. By utilizing the advanced SealBoss Injection System, the team achieved lasting results, showcasing the importance of specialized training, the right equipment, and strategic application in preserving concrete structures.

This guide provides valuable insights into the problem of tie holes, effective sealing techniques, and the critical role of expertise in ensuring durable repairs.

What are Tie Holes in Concrete Structures and How to Seal Them Permanently

Tie holes are small openings left in concrete structures after the removal of tie rods, which play a critical role during construction. Tie rods are essential components of concrete formwork—the temporary mold used to shape poured concrete. These rods ensure proper alignment and stability of the formwork during the concrete pouring and curing processes.

Over time, tie holes can become a vulnerability in the structure, as they may begin to leak when exposed to hydrostatic pressure. This typically occurs when water from an external source presses against the opposite side of the concrete structure, leading to potential water infiltration.

Sealing Tie Holes with SealBoss Systems — Polyurethane Polymer Foam Injection is widely regarded as one of the most effective and long-lasting solutions.

This advanced sealing technique permanently stops leaks in tie holes, providing durable protection against water penetration. Its efficiency and reliability make it a top choice for maintaining the structural integrity of concrete constructions.

By understanding the importance of sealing tie holes and utilizing proven methods like polyurethane foam injection, you can prevent water damage and extend the life of your concrete structure.

Sealing Tie Holes and Cracks

A Case Study in Effective Water Tank Repair

Polyurethane Polymer Foam Injection is an effective method to seal leaking tie rods permanently

In the world of construction, particularly in the construction of water tanks, shrinkage cracks and tie-holes are common issues that can lead to slowly weeping or even significant leaks. These problems are often accompanied by visible efflorescence, signaling a need for immediate and effective repair.

A recent project by a contractor in a rural water district expansion north of Atlanta, Georgia, perfectly illustrates how these challenges can be met with the right expertise and equipment.

Encountering the Challenge

During the construction of water tanks in this project, the contractor encountered both shrinkage cracks and tie-holes showing signs of leakage.

To address these issues effectively, the contractor sought on-site support and comprehensive systems training, specifically in the use of SealBoss 1510 NSF Hydrophobic Water Stop Foam and the P2002 High-Pressure Injection Pump.

The Training and Repair Process

The training began with a thorough inspection of the tank to identify the most actively leaking areas.

This was followed by a demonstration of the SealBoss Injection System application. The repair process involved a strategic approach to drilling holes:

The 1, 2, 3, 45 Degree Injection Method was used for the shrinkage cracks, and for sealing the tie-holes, a 45-degree hole was drilled 4 inches from the edge of each tie-hole until the steel insert was reached.

Preparation and Injection

Before the injection process, each drilled hole was pre-injected with water using a spray bottle. Given the ambient temperature of 38 degrees Fahrenheit, hot water (between 70 and 90 degrees Fahrenheit) was used for pre-injection to assist with the catalyzation time of the 1510 foam in the cold concrete. After flushing the holes, the installation of the SealBoss 13-100 AL Evolution Mechanical Packers commenced, followed by the injection process using the P2002 high-pressure injection pump.

Hands-On Learning and Independent Operation

The P2002 pump, known for its simplicity and drill-operated mechanism, was explained in detail. The training emphasized understanding injection pressure and the patience required for successful application.

Initially, the technician assisted with the pump operation, but within 10 minutes, the crew was able to inject independently.

Each packer was injected until there was positive refusal of material around each tie hole, and the same process was applied to the cracks.

Ensuring Long-Term Success

Once the crew gained confidence in operating the system, the focus shifted to cleaning and maintenance of the pump, ensuring its longevity and effectiveness for future projects.

Conclusion

This project north of Atlanta, Georgia serves as a prime example of how proper training and the right equipment can effectively address leaking tie holes and shrinkage cracks in new water tank construction.

The use of SealBoss 1510 NSF hydrophobic foam and the P2002 high-pressure injection pump, combined with hands-on training and a strategic approach to sealing, provided a durable solution to the problem of shrinkage cracks and tie-holes.

This case study not only highlights the importance of addressing these construction challenges promptly but also demonstrates the value of expert guidance and training in ensuring the longevity and integrity of water storage facilities.

Injecting Trust - One Crack at a Time

Introduction

Cracks in concrete structures are more than just cosmetic issues—they can compromise integrity, allow water intrusion, and accelerate rebar corrosion. The SealBoss 1-2-3 at 45 Degree Crack Injection Guideline provides a proven, systematic approach to crack injection that ensures effective leak sealing and structural protection. By following three critical steps—preparing and mapping packer placement, installing the packers, and executing the injection at a 45-degree angle—contractors can achieve durable, high-quality results. This article outlines best practices, technical details, and important considerations to help professionals optimize their injection process and maximize success, one crack at a time.

The SealBoss 1-2-3 at 45 Degree Crack Injection Guideline

  • Step 1 – Preparing and Mapping Out Packer Placement
  • Step 2 – Installing the Packers
  • Step 3 – Executing the Injection Process
  • 45-Degree Angle – Recommended Packer Angle / Positioning Guideline

Optimal Techniques and Considerations

The SealBoss 1-2-3 at 45 Degree Injection Guideline highlights the three fundamental steps of the injection process while emphasizing the importance of a standard 45-degree angle for packer placement. Although the 45-degree angle is a widely accepted practice, certain situations may require deviation from this rule, as discussed in this article.

Additionally, it is advised to target each injection port three times during the injection procedure – as a general rule – to ensure adequate density and penetration of the chemical grout within the structure. Injection Packers that persistently absorb product should be injected repeatedly, as many times as needed, to ensure a lasting seal.

Injection Packer Spacing

Mechanical injection packer spacing, also referred to as port spacing, in the context of leak-seal crack injection is contingent upon several site-specific conditions, such as crack width, substrate thickness, water flow, and product properties.

In numerous instances, an 8-inch (20 cm) to 1-foot (30 cm) on-center spacing serves as a suitable initial distance. Hairline cracks necessitate tighter spacing, as the product is less capable of traveling far. Consequently, the tighter the cracks, the closer the required spacing.

Injection Packer Placement

In the majority of cases, injection packers should be arranged in a staggered manner by alternating drill holes to the left and right of the crack while drilling at a 45-degree angle toward the crack, thereby forming a stitch grouting pattern. This method enhances the likelihood of intersecting the crack during drilling and reduces the probability of concrete cracking and spalling during packer installation or the high-pressure injection process. Injection should commence from the bottom and proceed upward.

45 Degree Angle Drilling and Packer Placement

The optimal method for packer placement involves positioning at a 45-degree angle. For structures with a thickness exceeding 6 inches (12-15 cm), SealBoss recommends a 45-degree angle as the most effective strategy for intersecting the crack at the midpoint of the structure. This is accomplished by initiating drilling a few inches to the left or right of the crack at an angled trajectory toward the crack itself, rather than drilling directly into it. This technique enables the requisite “inside-out” product flow for optimal crack penetration.

For instance, in a 10-inch thick concrete wall, one should move approximately 4-5 inches (8-10 cm) away from the crack and drill at a 45-degree angle toward it to attain the desired target. Initiating drilling with a straight entry and subsequently angling the drill at the required angle is beneficial.

Typical drill spacing along the crack’s surface ranges between 6-12 inches (10-20 cm) depending on the crack’s thickness. Hairline cracks necessitate closer spacing than larger cracks, as the material will not travel as far. Stagger drill holes from one side of the crack to the other, intersecting the crack during drilling.

Optimizing Drill Hole Distance from the Crack 

When determining the spacing of drill holes from a crack for chemical grout injection, it is essential to understand the relationship between the hole’s distance from the crack and the depth at which it intersects the crack. Here is a detailed explanation:

  • Depth of Intersection: The greater the distance between the drill hole and the crack, the deeper is its intersection with the crack inside the structure, leading to a deeper point of injection.
  • Considerations for Thicker Structures:  In thicker structures, a deeper injection point is usually favored. Yet, it is essential to factor in the drill bit’s length and reach, as they play a crucial role in determining the optimal distance for the drill hole. Always allow for a margin of error and ad at least a margin of 2 inches to the calculated drill bit reach needed.
  • Avoiding Dead-End Drill Holes: A drill hole that misses the crack cannot facilitate the injection of the chemical grout into the structure. Such holes are termed “dead-end drill holes” and are ineffective for the purpose of grout injection.

Determining the Required Minimum Length for a Drill Bit

When drilling at a 45-degree angle, we encounter a specific triangle called the 45-45-90 triangle, which follows the principles of the Pythagorean theorem.

In this 45-45-90 triangle, both legs, marked “X”  are of equal length. X is the distance the drill hole is placed away from the crack. Therefore, when drilling at a 45-degree angle, if we assume the crack is perpendicular to the surface, the depth at which the drill hole intersects the crack will be the same as the distance of the drill hole from the crack. To determine the minimum drill depth, or the distance from the drill hole surface to the crack, use the formula:
Distance from crack X √2, which is approximately 1.414.

To simplify and account for variations we use the factor 1.5 to calculate the absolute minimum drill hole depth necessary to intersect the crack. 

For a 5-inch distance from the crack, the calculation would be: 5 × 1.5 = 7.5 inches. Therefore, the drill hole should be at least 7.5 inches deep to guarantee intersection with the crack for injection in near perfect conditions.

For a 6-inch distance from the crack, the calculation would be: 6 × 1.5 = 9 inches. Therefore, the drill hole should be at least 7.5 inches deep to guarantee intersection with the crack for injection in near perfect conditions.

Now add at least 2 inches of drill bit reach to the calculation. It is essential to remember that not all cracks might run perfectly perpendicular to the surface, so always consider the specific conditions of your project.  

In summary, while determining the placing of drill holes, it is important to balance the desired depth of injection with the capabilities and reach of your drilling equipment to ensure effective grout injection.Remember, the effective reach of a drill bit and its actual length differ.

Always ensure your drill bit has the necessary length to effectively intersect the crack!

General Injection Packer Preparation – Drill and Flush


Safety Gear

Consistently wear appropriate protective gear and goggles, adhering to data sheet and SDS instructions.

Cleaning

If required, clean the crack or joint’s face using a wire brush, pressure washing, or similar method. A clean surface facilitates the identification of cracks and problematic areas.

Spacing

Mechanical injection packer spacing, also known as port spacing, is contingent upon various site conditions such as crack depth and width, substrate thickness and state, water flow rate, and the product’s physical and chemical properties.

An 8-inch (20 cm) to 1-foot (30 cm) on-center spacing is suggested for the majority of situations. Hairline cracks necessitate tighter spacing compared to wider cracks. The tighter the cracks, the closer the required spacing, as the product must travel deeply enough into the structure to form a permanent seal.

Determine the spacing, pattern, and depths of the drill holes. Based on the crack’s width, space the packers at a distance of approximately 6-18 inches (10-45 cm). The tighter the cracks, the closer the required spacing. Hairline cracks result in limited water stop and leak-seal grout travel, necessitating tighter packer spacing, while wider cracks permit easier flow and broader packer spacing.

Stagger drill holes from one side of the crack to the other (left/right), thus forming a stitch grouting pattern. This technique increases the chances of intersecting the crack during drilling while decreasing the likelihood of cracking and spalling the concrete during packer installation and the high-pressure injection process.

Typically, injection should begin at the bottom and move upward, pushing the product against gravity and water flow, thereby achieving a higher density in the process.

Exceptions to the 45 Degree Injection Rule – Straight Drilling

As with any rule, the catchy SealBoss 1-2-3 at 45-Degree Rule has its limitations and exceptions. Here are three notable examples:

  • Drilling into Joints
    Drilling into joints, such as concrete tunnel segments, is predominantly performed in a straight manner.

  • Thinner Stuctures
    Concrete structures with a thickness of less than 6 inches may not permit angle drilling, as this can result in cracking and spalling of the concrete.

  • Badly Deteriorated Substrate
    Similar issues can occur in severely deteriorated concrete substrates and in concrete of inferior quality. In such situations, it is recommended to drill and install packers directly into the crack without completely penetrating the structure.

SealBoss offers an extensive range of injection equipment and pumps to accommodate your project. Consult a SealBoss technician for detailed information and assistance. We look forward to helping you with your project.

Drill Dust

When drilling deeper holes, periodically extract your drill bit to remove drilling dust and prevent your drill from binding up.

Rebar

Most concrete structures contain rebar steel reinforcement to provide structural strength. In an ideal, crack-free structure, concrete protects the rebar from corrosion by insulating it from moisture and air while maintaining a high pH environment. However, when cracks form, this shield is compromised, allowing air, environmental gases, and water to cause carbonation, and subsequently corrosion of the rebar, which  forms rust expands to expands its original volume. The expansion of rusted rebar exerts high forces against the concrete, resulting in further deterioration, cracking, and spalling. Chemical grout injection protects rebar and can mitigate these processes.

Rebar often slows down the drilling process. When your drill bit contacts rebar, the sound changes, the quantity of drilling dust may be reduced, and the progression slows down or may even stop.

Some drill bits enable drilling through rebar, although this is generally not recommended and may even be prohibited, as it can weaken the concrete structure. In such cases, relocating the drill hole is the only option. If you repeatedly hit rebar, consider drilling straight into the crack. Dead-end drill holes, the holes that are not used for injection, must be patched and sealed before injection to prevent leakage.

Flushing / Cleaning Drill Holes Prior to Injection

Overview

Drilling debris can thicken the product during injection, resulting in higher injection pressures and reduced penetration in fine cracks. It is best practice to remove concrete dust and debris from the drill holes by flushing with a water hose until clean water is observed. You can use a water hose to flush debris from the hole.

Vacuuming out the dust can also be helpful if flushing is not possible.

Blowing out the debris is another option; however, be aware that dust can be an inhalation hazard, and appropriate gear is mandatory.

Flushing / Cleaning of holes is not necessary if water is actively running from your drill holes.

Drill Hole Water Flushing Detail

Low Pressure Flush

For low-pressure flushing, simple tools like a plastic water squeeze or spray bottle suffice. This method can remove debris from the drill hole and introduce water into the drill hole.

If available on site, a water hose can be used to flush the drill holes.

Using a Dedicated Flushing Water Pump

A dedicated water injection pump is suitable for both low-pressure drill hole flushing with a hose and on-site pressure crack flushing with water through injection packers.

While drill hole flushing serves to remove debris from the hole only, high-pressure water flushing can provide insights into material flow, expected product penetration distance, and introduce moisture to enhance product reactivity.

For such high-pressure applications, a dedicated water flushing pump is essential.

After clearing the drill hole, an injection packer is positioned. The water pump is then linked to channel water under high pressure via the injection packer into the into the crack, flushing it in the process.

If the crack remains unresponsive to taking on water, it might indicate that the hole is not linked to the crack. In such cases, a new drill hole has to be established and retested with water.

While high-pressure flushing is not typically required for most injection projects, it can offer benefits in specific scenarios.

It is imperative not to use the same pump for water injection that you use for dispensing polyurethane resin. Given that polyurethanes are activated by water, even the slightest moisture can result in pump malfunction.

Final Thoughts

Equipment limitations may render flushing infeasible; however, most injections will succeed without additional water introduction, even in seemingly dry crack environments. If the product does not immediately contact water, it will cure over time as natural moisture in the concrete stimulates curing and hardening, potentially at a slower pace.

Additional Injection Packer Installation Recommendations

Mechanical Packer Fundamentals

For optimal performance, packers and drill holes must possess adequate quality to endure injection pressures without leakage or displacement within the crack. Notably, even superior packers may rupture or leak under certain conditions. SealBoss Mechanical Packers, available in various sizes and designs, are recommended for pressure injection. These packers feature a threaded shaft with a rubber base; upon insertion, tightening the shaft compresses the rubber within the drill hole, generating a compression seal. Standard packer diameters range from 1/4 to 3/4 inches, with industry norms between 3/8 and 5/8 inches. In poured concrete substrates, drill holes serve as solid channels directing resin to the crack, enabling the use of shorter packers. In substrates with potential voids, such as block walls, stone, and brick, SealBoss advises employing longer packers to ensure a definite grout delivery channel to the crack being sealed.

Mechanical Packers Installation

To seal against the drill hole, mechanical packers require tightening, which expands the rubber seal. Packers may be pre-tightened by hand to seat the rubber snugly, approximately 1/4 inch (5 mm) inside the drill hole. Correct installation prevents concrete cracking around the drill hole’s exterior. Depending on packer design, using an appropriate ratchet/nut, wrench, or electric driver for tightening is highly recommended. Packers should be securely tightened to withstand injection pressures without over-tightening.

SealBoss Hammer-In Ports

SealBoss Hammer-In Ports are also frequently utilized. These ports are seated using a hammer at moderate force, with an electric driver or hand tool and a suitable socket employed to screw the zerk fitting into the port. Hammer-in ports typically do not achieve the same injection pressures as mechanical packers and should be reserved for applications where maximum injection pressures are not essential.

Packer Connectors

Packers are typically equipped with a quick-connect system, either a zerk type or button head/slide coupler type.

Zerk Type Connector

The zerk type is most prevalent. Applicators must push the coupler over the zerk fitting and maintain alignment with the packer. To disconnect, applicators “break” the connection by pushing the connector sideways.

Button Head / Slide Coupler

The button head type provides a more secure connection. The operator slides the coupler on and off the packer, ensuring a secure, tight connection that is less prone to unintended disconnection and leakage. When executed properly, the applicator does not need to hold the coupler in place, a significant advantage in overhead injection and instances requiring large product volumes through one packer.

SealBoss Packers

SealBoss offers an industry-leading array of injection packers and ports for diverse situations and requirements. Contact a SealBoss representative for packer recommendations tailored to your project.

Injection Products


Before You Start Injection

Before injection, review the product datasheet instructions. Ensure your pump is in fully operational condition and completely devoid of moisture before preparing SealBoss Water Stop and Leak Sealing Products for injection.

It is prudent to flush the pump with SealBoss R70 before using any resin/foam grout.

Injection Procedure

When products are prepared for injection, have a cup available to dispose of some resin to ensure purity. Start the pump at the lowest pressure setting. After connecting your grout injection hose to the secured and tightened packers, initiate the injection process.

Use the shut-off valve at the injection hose’s end whenever the hose is moved, remember that some pumps need to be manually stopped .

Starting from the bottom, securely connect your injection line to the packer and commence with the lowest pressure capable of moving resin into the crack. Generally, injection pressure will decrease as material flows, but pressure may need to be increased as products thicken and move into tighter cracks and fissures.

Maintain a slow injection rate as resin begins to show and flow from the crack. Pausing and restarting the process for a minute may be necessary to allow material reaction and thickening.

Monitor consumption rates and cease injection when consumption equals leakage. A typical observation involves reduced water flow from the crack’s face and/or reacting material exiting the crack’s face. This indicates successful penetration and results.

If the product does not advance along the crack, disconnect and proceed to the next port. Applicators must ensure sufficient material is injected into each crack to achieve optimal product density for a durable seal.

It is recommended to inject three to five packers while observing product flow, travel, and refusal from the crack.

Reinjecting those three to five packers—typically up to three times (1-2-3 at 45 degrees) or until product refusal—is crucial. The crack must be adequately filled with as much product as possible without excessive product loss from the crack. Sufficient material consumption and product density in the injected area must be monitored to achieve a solid and successful repair.

Injection Packers that continue to consume considerable product amounts should be injected a third time or as often as necessary to create a permanent seal.

SealBoss Oakum Soakum Technique

In cases where excessive resin flows out or washes out due to high water flow, resin-soaked SealBoss Oakum can be employed to form a temporary plug, allowing the product time to react, expand, and seal.

Caution: Be prepared for the possibility of product ejection from the structure or around drill holes, as well as packer blowouts. High-pressure injection equipment may cause product to travel further than anticipated, potentially appearing several feet from the injection point. Small cracks may become visible after the injection process.

Quality Injection Job

Injection often necessitates a two-person team, with one individual operating the valve and hose while another manages the pump. Create a dense seal! Inadequate material consumption alone can yield differing results in the same injection application. If the crack is not accepting any product, it may be due to insufficient drilling depth or crack direction on the opposite side. In such cases, drill from the opposite side of the crack and ensure intersection with the crack.

Packer Removal

Once the material has fully cured, packers can be removed by loosening the shaft. Some applicators opt to leave the rubber base in the wall and patch the drill hole, while others remove the entire packer before patching. In certain injection applications, packers may remain in place permanently. This decision is at the discretion of the applicator or owner. A final cleaning of the crack’s face is necessary to remove cured product using a wire brush, pressure washing, or other appropriate methods. The substrate is then prepared for the final finish.

SealBoss R70 Pump Flush for Clean-up

DO NOT CLEAN WITH WATER. If allowed on the job, initially flush all dispensing equipment with a small amount of solvent, such as xylene, to cut the product. Follow this step by generously flushing with SealBoss R70 Pump Flush & Cleaner to protect hoses and lubricate the pump. Avoid using solvents for the final flush, as this can reduce the lifespan of your equipment.

Exception – Equipment for SealBoss 2400 Acrylate is cleaned with water. Consult the data sheet for details.

Caulk Grade Swelling Waterstop

Caulk Grade Swelling Waterstop

Caulk Grade Swelling Waterstop - Single Component - SealBoss

SealBoss® SwellCaulk™ – Caulk-Grade Swelling Waterstop for Cold Joints and Concrete Sealing

An Overview of SealBoss SwellCaulk

In concrete construction, water intrusion is one of the most persistent threats to structural durability and performance. Construction joints, cold joints, and pipe penetrations are particularly vulnerable to leakage, especially in below-grade, submerged, or high-moisture environments. Enter SealBoss SwellCaulk™—a next-generation, high-performance caulk-grade swelling waterstop developed specifically to combat these challenges.

What is SealBoss SwellCaulk?

SealBoss® SwellCaulk is a single-component, polyurethane-based, hydrophilic waterstop and leak-sealing caulk grade swelling waterstop paste designed for easy application and long-lasting waterproofing. The product is engineered to react with water by expanding up to 350% of its original volume, effectively sealing gaps and voids in concrete joints.

  • Single-component system – no mixing required
  • Water-activated expansion for maximum sealing power
  • Extremely adhesive – bonds to concrete, even when rough or damp
  • Flexible and moldable to irregular joint surfaces

Packaging Formats for On-Site Versatility

SealBoss SwellCaulk is available in two user-friendly packaging formats:

  • Cartridges – For use with standard caulking guns
  • Sausages – For use with common sausage-style applicator guns

These application options allow field teams to adapt to specific project conditions and scale—from small detailing work to long joint runs on large concrete slabs or walls.

How SwellCaulk Works: Hydrophilic Expansion and Active Sealing

The core innovation behind SwellCaulk lies in its hydrophilic polyurethane composition. Upon exposure to water, this Caulk Grade Swelling Waterstop undergoes a controlled expansion, growing up to 3.5 times its initial volume while creating a permanent compression seal. This physical expansion enables the product to fill gaps and irregular surface areas, forming a dense, resilient, and water-impermeable seal.

  • Self-adheres to dry or moist concrete
  • Eliminates need for primers or adhesives
  • Adapts to rough, porous, or irregular substrates
  • Forms watertight seals even in uneven joints

SwellCaulk as a Pressure-Positive Compression Seal

Unlike conventional caulks that merely sit in a joint, SwellCaulk becomes an active barrier once confined and hydrated. Its expansion creates a compression seal, pressing outward against joint walls to establish a pressure-positive seal—blocking water flow even under significant hydrostatic pressure.

  • Withstands considerable hydrostatic pressures
  • Provides permanent, resilient water sealing
  • Ideal for below-grade, wet, or submerged conditions

Understanding Cold Joints—and Why They Need SwellCaulk

Cold joints form when a new batch of concrete is poured next to an existing pour that has already begun to set. These unbonded seams can act as fine channels for water migration, creating long-term leakage problems.

Despite appearing solid from the surface, cold joints are inherent weak points in a concrete structure.

SwellCaulk is engineered to permanently seal cold joints. Its expanding action allows it to create a strong bond with both concrete layers, forming a continuous, flexible and active seal.

  • Designed to seal cold joints in cast-in-place and precast concrete
  • Seals non-bonded gaps caused by pour delays
  • Creates a permanent watertight barrier at potential failure points

Typical Applications of SealBoss® SwellCaulk

SwellCaulk – Caulk Grade Swelling Waterstop, is a versatile solution suitable for a broad range of structural applications where waterproofing is essential:

✔️ Cold joints and construction joints in concrete
✔️ Sealing pipe and conduit penetrations through slabs and walls
✔️ Joints between precast concrete elements
✔️ Transitions between new and existing concrete
✔️ Horizontal, vertical, and overhead surface applications
✔️ Adhesive for SealBoss SwellTape installations
✔️ Sheet pile interlocks, utility vaults, manholes, and more

Key Advantages of SealBoss SwellCaulk:

✔️ Expands up to 350% – Strong hydrophilic action
✔️ Thixotropic formulation – No slump, sag, or run
✔️ Adheres to rough, smooth, and uneven surfaces
✔️ Works in vertical, horizontal, or overhead joints
✔️ Forms pressure-positive compression seals
✔️ Permanently water-resistant
✔️ No leaching or material breakdown in water
✔️ Withstands repeated wet/dry cycling
✔️ Requires no mechanical fastening, glue, or hooks
✔️ Controlled expansion eliminates cracking in concrete
✔️ Excellent chemical resistance
✔️ Great resistance to vibration and joint movement
✔️ No mixing, simple and efficient field application
✔️ Economical and cost-effective waterproofing solution

Jobsite Benefits – Time and Labor Savings

  • Ideal for contractors handling large-scale or repetitive injection work

“SealBoss aluminum injection packers are the economic alternative for most standard injection scenarios. They’re much lighter to carry, cheaper to ship, and easy to handle on-site.”

⚙️ Installation and Use

  1. Drill a hole at a 45° angle into the crack or cold joint.
  2. Insert the packer and tighten the bolt or nut, expanding the rubber sleeve to secure it in place.
  3. Connect your injection pump to the Zerk fitting or grease nipple.
  4. Inject your chosen resin (PU, Acrylate Gel, etc.) under pressure.
  5. Remove the packer after curing, or leave it embedded depending on specifications.


Limitations to Consider

While SealBoss aluminum injection packers are excellent for most day-to-day applications, they may not be suited for every scenario. Their strength is slightly lower than SealBoss S-Type steel or SealBoss B-Type brass packers, and they may not be the ultimate choice for:

  • Steel Packers Specified Jobs

Watertight Pipe Penetration Sealing

Watertight Pipe Penetration Sealing

Guidelines for Pipe Penetration Waterproofing

Introduction

Waterproofing pipe penetrations is a critical task in maintaining the integrity of a structure housing utility systems. Ensuring that pipes and conduits passing through walls or floors do not allow water ingress is essential for preventing damage and maintaining safety, especially in environments with high moisture or any water exposure. This guide provides a comprehensive overview of the steps and techniques necessary for effective pipe penetration waterproofing and sealing.

It covers the basics of installing new or replacing failed water stops around existing pipe penetrations, utilizing a range of products and techniques to seal these areas effectively. Whether you are dealing with active leaks, dormant leaks, or the unwanted migration of pollutants or gases such as exhaust fumes, unsealed pipe penetrations and conduits require an understanding of the best sealing procedures for your specific situation, this guide, along with the expert assistance of SealBoss technicians, offers the knowledge and solutions needed to address these challenges confidently.

How to Replace failed Water Stop around existing Pipe Penetrations

Step 1: Clean the area – Begin by eliminating any old grout or deteriorated concrete from around the pipe penetrations. Ideally, remove material to a depth of at least 1″ and a width of 1/2″ all around the pipe’s circumference. In this demonstration, an air chisel was utilized adhering to the safety protocols outlined by the natural gas plant.

Step 2: Clear the debris – After the removal of old grout or concrete, it’s essential to thoroughly clean the area. Employ a brush, air blower, or vacuum cleaner to eliminate any remaining dust or loose particles.

Step 3: Initiate the repair process – Once the area is clean, you’re ready to proceed with the installation of the repair products. Your pipeline is now prepped for the restoration process to commence.

Utilizing Multiple Products and Techniques for Pipe Penetration Sealing

Oakum Saturation with Foam Grout

Oakum Soakum Installation

The process starts by unwinding and snipping an adequate length of Oakum rope to encircle the part of the pipe where it breaches the wall. The installer will initially manipulate and expand the Oakum, augmenting its surface area for better adherence with the catalyzed resin.

Next, using a zip-top bag or a bucket, dispense a sufficient quantity of SealBoss 1510/1570 resin to comprehensively saturate the Oakum strand. Following this, add the desired 15x catalyst concentration of 5% – 20%, contingent on the intensity of the leak.

The catalyst ratio dictates the reaction time and expansion rate. For dormant leaks, we recommend a catalyst percentage of 5% to 10%, and for active leaks, a proportion of 10% to 20% is suggested. Our technical representatives are available for any queries related to catalyst ratios.

After thoroughly soaking the Oakum, swiftly wrap it around the pipe, manipulating the fibers to fill as much of the pipe penetration annulus as possible. This forms a gasket-like sleeve around the pipe. Spray the soaked Oakum with water to facilitate the foam’s catalyzation. Within moments, you’ll observe the foam starting to form and expand.

Upon the foam’s complete curing, consider the repair concluded successfully.

  • In areas of constant hydrostatic pressures it is often recommended to inject the circumferential void throughout the thickness of the wall using SealBoss 1510 or 1570 Water Stop Foam.
  • With the use of a SealBoss Grout Injection Needle and a low cost HP1500 Ultra Light Hand Gun or a HP 100 Hand Pump, the foam grout can be conveniently placed and injected into the void. Depending on the conditions at the jobsite, the injection can be performed following the ‘Oakum Soakum Procedure’, by penetrating the initial repair with the injection needle and inject SealBoss Water Stop Foam behind it.
  • For small jobs and pipe diameters, and for low cost applications where hand pump and injection needles are not feasible, SealBoss Can-Seal Foam can be used as a lower grade alternative.

Upon completion of the leak-sealing application, carefully remove any surplus cured foam protruding from the annulus to ensure a clean working area for the subsequent application of grout or mortar around the pipe penetration.

  • SealBoss SwellCaulk is a premium, single-component hydroactive sealant, specifically designed to expand upon contact with water, thereby creating a secure, watertight seal. This product is especially effective for repairing pipe and cable penetrations. For optimal results with SwellCaulk, apply a bead of an appropriate size around the pipe, extending it beyond the chipped area and up to two inches deep into the circumferential void. Upon exposure to moisture, this hydrophilic material initiates its expansion process, thereby effectively forming a watertight seal around the pipe.
