Retaining Wall Crack Injection Repair

Using Leak Sealing Foam

Retaining Wall Crack Injection Repair using Leak Sealing Foam offers a swift and dependable solution to address cracks responsible for water infiltration and subsequent erosion. Here is a quick guide to this repair process:

1. Site Preparation
Begin by ensuring the site is ready for the repair. Clear away any debris, dirt, and loose materials to provide a clean working surface.

2. Crack Assessment
Identify and evaluate the cracks in terms of their depth and length. While visible cracks are obvious targets, it’s crucial to be vigilant about potential hidden cracks that might escape a cursory glance. Such concealed cracks might necessitate a more thorough examination.

3. Drilling Injection Point Holes
Once the cracks are mapped out, drill holes into the retaining wall. These should be spaced roughly 12 inches apart, running along the entirety of each crack.

4. Packer Installation
Insert the injection packers into the freshly drilled holes, ensuring they’re firmly anchored. These packers act as conduits for the polyurethane foam during the injection phase.

5. Foam Injection
With the packers in place, it is time to inject the prepared leak sealing foam. Utilizing the appropriate equipment, start the injection at the lowest point, working your way up. Continue this process until the foam either refuses to enter further or you’ve covered the entire crack.

6. Curing and Final Touches
Post-injection, allow the polyurethane foam ample time to cure, adhering to the manufacturer’s guidelines. Once cured, remove the packers and seal the holes using a compatible sealant.

In summary, the use of leak sealing foam for Retaining Wall Crack Injection Repair is a tried-and-true method, ensuring cracks are effectively sealed, preventing any future water ingress.

Retaining Wall Crack Injection Repair with SealBoss 1510 Leak Sealing Foam

When it comes to the restoration of older commercial buildings, retaining wall crack injection repair emerges as a crucial method for preserving architectural integrity. A recent case involved a 50-year-old commercial structure that required rehabilitation, particularly for its below-grade retaining wall. This wall, adjacent to a staircase, displayed multiple through cracks and evident efflorescence.

Choosing the Right Repair Product

Given the challenges posed by groundwater seepage, especially after heavy rainfall, SealBoss 1510 Leak Sealing Foam was chosen for the job. This product was injected at high pressure to address the cracks before the concrete wall underwent refacing.

Insightful Inspection

A detailed inspection revealed that the main, larger cracks were accompanied by smaller, branching cracks. The retaining wall, showing clear signs of honeycombing and pitting, was constructed with an 8-inch thickness. However, the design and layout of the rebar remained unknown.

Strategic Packer Placement

The unique challenges of this retaining wall crack injection repair, such as uncertain rebar spacing and the wall’s relatively shallow thickness, necessitated a deviation from the standard. Instead of placing injection packers at the conventional 45-degree angle, they were positioned directly into the cracks.

This “in the crack” packer placement minimized the risk of hitting rebars during drilling. Given the wall’s 8-inch thickness, this method ensured the injection foam penetrated effectively, sealing the structure and halting water flow. Drill holes, spaced roughly 12 inches apart, were drilled to a depth of around 4 inches. These holes were then cleaned with warm water to remove any dust, prepping the crack for injection. Subsequently, SealBoss 13-100AL Evolution high-pressure injection packers were installed, recessing the rubber section by about ½-inch.

More information on recommended injection packer placement can be found here.

Product Conditioning

Considering the low ambient temperatures of 34F/1C, the SealBoss 1510 Leak Sealing Foam was conditioned with a higher ratio of SealBoss 15x Accelerator, approximately 20% by volume, as opposed to the usual 10%.

Injection Process

With the SealBoss P2002 Pump filled with a thorough mix of 1510 Foam and 15x Accelerator, the injection process began. Starting from the lowest packer, the procedure moved vertically upwards. The injection was paused intermittently whenever the catalyzed 1510 foam visibly emerged from the crack. This allowed the foam to cure, ensuring the subsequent hydrophobic resin injection would effectively seal any remaining capillaries within the crack.

The result? Every crack underwent the retaining wall crack injection repair process to specification, successfully halting stopping all water intrusion and seepage.

Joint Filler Maintenance – Elongation, Separation, Repair

Technical Bulletin

Joint Filler Maintenance
Elongation - Separation - Repair

A Concise Guide for Ensuring Optimal Performance and Longevity of Your SealBoss Joint Filler

Safeguarding the Durability of Your Concrete Joints

Background

The tensile elongation of semi-rigid joint fillers is a common characteristic to consider. Ultimate tensile elongation pertains to the degree of expansion a material can undergo, in terms of its length, before succumbing to fracture under tensile force. It is a common misconception, that employing a joint filler with a high elongation value can facilitate early joint filling in new flooring, with the filler then able to ‘stretch’ in accordance with the joint as it expands due to slab shrinkage.

This reasoning is flawed.

Tensile testing gauges the capacity of the joint filler material to stretch along the test specimen’s length. However, control joints in concrete floors don’t lengthen but rather widen laterally — side-to-side . Thus, the tensile elongation test does not accurately simulate real control joint movement or the joint filler’s capacity to accommodate this movement.

Consider the polyurea joint filler with a tensile elongation of 200%. It can stretch laterally — side-to-side — approximately 10% before it starts to split either cohesively (within the filler itself) or adhesively (along the joint filler/concrete bond line). Given that the shrinkage-induced joint widening often surpasses what the joint filler physically can withstand even under the best circumstances, early installation of joint fillers will likely lead to splitting or a loss of adhesion. Concrete shrinkage can cause the Joint Filler to split or separate over time.

This is a normal occurrence and not an indication of joint filler failure, and is clearly stated by the American Concrete Institute in the ACI 302.1R-04 Guide for Concrete Floor and Slab Construction, Section 9.10 – Joint Filling and Sealing

” 9.10.1 Time of filling and sealing—Concrete slabs-on-ground continue to shrink for years; most shrinkage takes
place within the first 4 years. The most significant shrinkage takes place within the first year, especially the first 60 to 90 days. It is advisable to defer joint filling and sealing as long as possible to minimize the effects of shrinkage-related joint opening on the filler or sealant. This is especially important where semirigid fillers are used in traffic-bearing joints; such fillers have minimal extensibility. If the joint should be filled before most of the shrinkage has occurred, separation should be expected between the joint edge and the joint filler or within the joint filler itself. These slight openings can subsequently be filled with a low-viscosity filler recommended by the same manufacturer as the original filler. If construction traffic dictates that joints be filled early, provisions should be made to require that the contractor return at a preestablished date to complete the necessary work using the same manufacturer’s products. Earlier filling will result in greater separation and will lead to the need for more substantial correction; this separation does not indicate a failure of the filler. …” (ACI 302.1R-04 – Section 9.10)

The Product

The SealBoss 6500 is a robust, semi-rigid polyurea joint filler, made entirely from solid materials. Composed of two components, it exhibits a Shore hardness of 80 A and approximately 200% elongation, indicative of its strength and flexibility. The product is primarily engineered for the purpose of filling and safeguarding contraction and construction joints found in concrete floors of industrial, retail, and commercial premises.

The formulation of SealBoss 6500 is purposefully designed to withstand the rigors of high-traffic and heavy-load environments typical of industrial and retail concrete floors. Its pivotal role is not just to withstand the continuous traffic in commercial warehouses and the load from forklift operations, but also to seal and safeguard joint edges. By doing so, it extends the longevity and maintains the integrity of the surfaces it is applied to. This makes it an indispensable solution for businesses that prioritize facility durability and maintenance.

Routine Maintenance and Cleaning

Ensure to sweep the polyurea joint filler daily to eliminate any accumulated dust or debris. For dealing with spills or hardened dirt, employ a solvent-free cleaner to dislodge the grime and proceed with your usual clean-up routine. For commercial floors that undergo auto-scrubbing, adhere to your regular cleaning protocols and perform spot cleaning as necessary.

In case the joint filler requires repair, please consider these steps:

Initiate by cleaning the area to remove any dirt and debris. Use a solvent to wipe off any residual grime, then fill the cavity with the 6500 filler. Use a floor scraper blade to remove any surplus filler, ensuring a level finish.

With a dust-free concrete saw or angle grinder equipped with a Brazed Vacuum saw blade, cut a depth of ½” (12mm) until fresh concrete is evident on both sides of the joint. Proceed to clean the filler surface by removing any dirt and debris, then wipe it with a solvent. Fill the void with polyurea joint filler and use a razor blade to shave off excess filler, resulting in a smooth finish.

Utilize a specialized removal blade, 4”, 6”, or 8”, to remove the full depth of the joint filler until fresh concrete is visible on all three sides of the joint. Once the joint is clean and free of all dust and debris, apply the new SealBoss 6500 as per the installation instructions.

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.

Culvert Repair – Leak Sealing Injection

Introduction

Culverts are essential infrastructure components that facilitate water flow beneath roads and railways, preventing flooding and erosion. However, leaks and structural damage can compromise their functionality, posing environmental and infrastructural risks. Learn how innovative repair systems, employing injection techniques and grouting methods to seal leaks and stabilize surrounding soil, can be utilized to repair culverts economically and effectively.

This quick guide explores the significance of maintaining culvert integrity through advanced repair solutions, highlighting the importance of addressing leaks and cracks to ensure the longevity and reliability of these underground waterways.

What exactly is a Culvert?

Functioning like underground tunnels, culverts are subterranean waterways, enabling the movement of water from one side of a roadway or another type of traffic embankment to the other side.

From an aerial view, a culvert might be also likened to a bridge, purposefully crafted to enable the transit of vehicles or pedestrian traffic over a water passage.

Various materials can be employed to construct culverts, such as corrugated steel pipe, reinforced concrete, or other suitable materials.

SealBoss Culvert Repair Systems

SealBoss delivers comprehensive solutions for the rehabilitation and leak repair of culverts, effectively sealing water seepage through cracks and joints.

Moreover, the SealBoss Culvert Repair Injection Systems are designed to fill any existing voids in the soil that surrounds the culvert and to stabilize any loose soil that may impair the traffic embankment above it. This is accomplished using permeation grouting techniques, which make use of low viscosity polymer foam resin, grout injection lances and appropriate pumping equipment.

With our repair systems the service life of a culvert structure can be extended at reasonable cost.

Culvert Damages and Inspections

Culverts, also known as storm culverts, are tunnel-like structures designed to enable water to flow beneath obstructions such as roads, railways, or trails. Typically enveloped by soil, these culverts, when compromised by leaks, can contribute to soil erosion and the formation of sinkholes, thereby potentially damaging the overlying structures.

SealBoss presents a range of cost-effective solutions for repairing culvert leaks and stabilizing soil permeation. These systems are designed to effectively address water leakage through cracks and cold joints, as well as the accompanying issues of soil erosion.

Failure to address deteriorating and leaking culverts can result in significant, potentially dramatic damage and risk to both the environment and infrastructural elements.

Basement Crack Repair

Basement Crack Repair - Injection Techniques

Introduction:

Maintaining the integrity of your home’s foundation is crucial, especially when dealing with basement wall, floor, and foundation cracks. These issues, if neglected, can escalate into major structural and moisture-related problems. This guide offers a concise overview of effective basement crack repair methods, including the use of polyurethane foam for waterproofing and epoxy resin for structural reinforcement.

Understanding how to properly address these cracks is key to preserving your home’s stability and value, ensuring a safe and dry basement environment. Through exploring various repair techniques, homeowners can find the most suitable approach to protect their foundation and extend the lifespan of their property.

Basement Wall, Floor, and Foundation Crack Repair

A Guide to Basement Crack Repair: Preserving the Integrity of Your Home’s Foundation

Your home’s basement is more than just a storage space; it is the solid base that holds your house together, literally. Consequently, it is critical to keep it in peak condition.

Over time, however, the basement might start showing signs of wear and tear, such as basement cracks. These fissures can be attributed to various factors, including drying shrinkage, thermal movement, shifting foundations, and foundation settling. Errors in the concrete mixing and application processes during construction can also contribute to the problem.

These basement cracks, seemingly harmless at the onset, can progressively multiply and widen. This deterioration can then lead to water seepage, causing a damp environment conducive to mold growth. This can also lead to a musty smell and even a significant compromise to the structural integrity of your home. The implications of these issues extend to the quality of living in the home and its market value. Therefore, maintaining a stable and dry basement environment, synonymous with a sound foundation, is of utmost importance.

Despite basement cracks being a relatively common occurrence, it is not advisable to ignore them. Homeowners should make it a habit to inspect the foundation wall and floor in their basement for any concrete cracks. Any identified issues should be promptly addressed to prevent further deterioration.

Approaches to Basement Crack Repair

There is a multitude of approaches to tackling basement crack repair. The method most appropriate is determined by the extent of the damage and the unique environmental conditions of the space.

Utilizing polymer resins and foams for injection constitutes an efficient and economical approach to mitigate basement leaks and restore structural integrity to basement walls and foundations.

Depending on the chosen products, these methodologies provide not only a pragmatic resolution to leakage problems but can also significantly enhance the durability and structural stability of the existing infrastructure. It is vital to discern between dry and wet basement cracks and understand their structural implications.

Resolving Water Intrusion with Polyurethane Foam Basement Crack Injection

Water intrusion through basement cracks can cause significant damage, leading to problems like mold growth and property depreciation. The introduction of basement crack injection with polyurethane foam has revolutionized the way these issues are addressed. Polyurethane foam expands upon contact with moisture, making it an excellent solution for sealing cracks and preventing water ingress. The foam fills the entire crack and forms an impermeable barrier against further water intrusion. This injection process is carried out from inside the structure, reducing the need for extensive excavation and offering a cost-effective, efficient solution for water intrusion concerns.
Strengthening Structures with Epoxy Resin Basement Crack Injection

For structural repair in basements, the crack injection process utilises epoxy resin, known for its high strength and durability. The injected epoxy hardens within the crack to form a rigid seal of high compressive and tensile strength, effectively restoring the structural strength of the cracked concrete. This process results in a permanent repair, reinforcing the structure and enhancing its longevity. By employing basement crack injection with epoxy resin, homeowners can ensure the maintenance of structural integrity, enhancing the safety and value of their properties.

The location of basement cracks often determines the extent of water permeation they may cause. In numerous scenarios, the primary goal is to establish a barrier against such seepage, necessitating the sealing of these cracks with polyurethane based products rather than enhancing their structural strength.

Conversely, there are situations where the restoration of structural stability of the wall or foundation becomes the primary objective. In these instances, epoxy resins emerge as the preferred choice due to their superior strength and bonding properties.

To understand this distinction more comprehensively, we recommend reviewing the Epoxy/Polyurethane Comparison article, which provides an in-depth analysis of the differential uses and benefits of these two material groups in basement crack repair.

Injection from the Inside – No Digging Required

A prevalent and convenient method of sealing cracks in concrete and concrete/cinder block basement walls is by injecting them from the inside. This repair process typically involves injecting polyurethane or epoxy crack materials into the cracks, offering a robust solution to water seepage and structural issues.

Concrete Structures

For cracks in poured concrete foundation walls, a monolithic and solid structure, a direct injection of chemical polyurethane grout or epoxy resin is the method of choice. The polymers fill the cracks and voids, and seal the structure in the process.

Poured Concrete versus Block Walls

Basement crack repair for concrete/cinder block foundation walls can present a different set of challenges. These walls, unlike poured concrete structures, are not monolithic. They are porous and constructed from numerous pieces held together with mortar, creating an abundance of cold joints, a convenient route for water penetration.

A cold joint is defined as the surface where an existing substrate and a fresh substrate, in this case, mortar, form a non-monolithic gap with no or very low bond strength. Due to these characteristics, block walls are usually more challenging to seal by direct injection. These often necessitate more extensive methods like curtain or bladder injection — moving chemical grout behind the structure from an inside injection grid pattern — to ensure water tightness.

Thankfully, in many situations — and more easily with poured concrete walls than block walls, for the reasons explained above — basement wall cracking can be remedied with basement crack repair kits. It is always recommended to get advise from a professional and licensed contractor prior to deciding on a crack repair strategy and a specific basement crack repair system.

To aid in your research, we’ve included links to some highly-rated basement crack repair kits, offering practical solutions for sealing basement wall and floor cracks. These resources, alongside additional crack repair-related information, will help you make an informed buying decision.

In conclusion, it is important to take basement cracks seriously, no matter how small or insignificant they might seem. While the task may seem daunting at first, remember that there are resources available to help. From basement crack repair kits for smaller tasks to professional contractors for larger projects, you have options. Therefore, do not neglect your basement; give it the care it needs, and it will support and protect your home for many years to come.
