Water Leaks

Multi Family Apartment Complex

Introduction

Water intrusion through pipe penetrations in apartment complexes can lead to significant structural damage, safety concerns, and costly repairs if not addressed promptly.

At a newly constructed apartment complex, persistent water leaks from a courtyard into an underground parking structure posed a serious challenge.

The leaking water caused concrete staining, erosion, and fire-stop material damage, jeopardizing the integrity of the building.

To tackle these issues, a certified SealBoss installer implemented a comprehensive and effective solution to seal the pipe penetration leaks.

Using advanced chemical injection grouting techniques and specialized SealBoss products, the contractor successfully resolved the problem, ensuring a watertight seal around the pipe penetrations and restoring the structure’s integrity.

This article details the step-by-step process and products used to address these complex leaks, offering insights into effective pipe penetration sealing solutions for multi-family apartment projects.

Multi Family Apartment Pipe Penetration Leak Stop

A certified SealBoss installer was engaged to resolve water intrusion issues at a new apartment complex, where water from a courtyard was leaking into the underground parking structure. This water was causing staining and erosion of the concrete floor and soaking into the fire-stop material. Upon investigation, it was found that rainwater and the courtyard’s irrigation system were the sources of the leaks.

The contractor employed a three-step approach to inject SealBoss 1510 Water Stop Foam into and around the affected pipe penetrations, successfully sealing the most problematic leak points.

Horizontal Blanket Injection: This technique filled the voids between the geofoam and poured concrete, creating a barrier around each pipe penetration. The contractor drilled strategically through the concrete deck and into the geofoam, placing injection packers to form an effective seal.
Area Draining and Packer Installation: After draining the area, injection packers were placed for a targeted injection of hydrophobic foam, addressing the initial leak sites.
Penetration Sleeves Sealing: A few days later, new leaks were detected around the pipe sleeves. For larger metal sleeves, the contractor drilled at a 45-degree angle toward the sleeve and injected SealBoss 1510 Water Stop Foam until a positive refusal around the sleeve was achieved. To contain the expanding material, SealBoss CanSeal Foam was used as a temporary backing and also to fill the voids between the concrete and ribbed steel sheeting.

SealBoss ® CanSeal Utility Foam is a specially formulated closed cell sealing foam — engineered to fully expand inside the applicator ‘gun barrel’. When the foam exits the tip of the gun it is already fully expanded, enabling you apply exactly as much foam as you need without the messy and undesired “mushrooming” experience you may have with most of the other ‘over the counter’ foam products.

Small Pipe and Pipe Penetration Leak Sealing Kits

SealBoss SealPipe Kit

For smaller pipe penetrations with poly sleeves, a Grout Injection Needle was utilized to inject foam into tighter spaces. Open-cell backer rod was inserted into the sleeve to contain the resin as the needle was withdrawn, allowing SealBoss 1510 Water Stop Foam to expand upward, effectively sealing the poly sleeve and stopping the leak.

This comprehensive approach enabled the contractor to stop the leaks successfully. Following the repair, the building owner was advised to re-evaluate the courtyard’s irrigation system to prevent future water intrusion into the underground parking area.

Sealing Tie Holes

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.

To address this issue, 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.

Epoxy Concrete Crack Injection Systems

Epoxy Crack Injection Resin can mitigate problems of cracked concrete with larger and fine cracks. ACI specifies cracks widths that are acceptable in structures under defined conditions. ACI 224R-012 provides a guideline for crack widths for reinforced concrete under service loads for new construction. Crack widths deemed acceptable may range from 0.004 in. (0.1 mm) to 0.016 in. (0.41 mm), and even smaller widths for concrete in wet or aggressive environments. These crack dimensions would be considered fine and hairline cracks.

Pushing the Envelope – SealBoss Epoxy Systems
– Resins, Pastes, Injection Ports and Pumps –

Epoxy Crack Injection

Cracking does not always affect structural performance, but it can adversely affect the durability of structures.

Common causes of concrete cracking are post cure and drying shrinkage, thermal stress, chemical reaction caused by alkali-reactive silica & sulfates, freezing and thaw cycles due to water expansion, corrosion of steel rebar, settlement, load stresses, construction short comings such as design and construction errors.

The incorporation of steel reinforcement within structural concrete allows these elements to function under both compression and tension, frequently resulting in tension-induced fracturing of the concrete in certain regions.

Water is a major contributor to concrete corrosion in parking garages, bridges, industrial facilities and more. Water, chloride and carbon dioxide can migrate deep into the structure initiating corrosion of the reinforcement structure.

Water ingress, facilitated by fissures or compromised joints, often carries corrosive substances and chlorides that contribute to the degradation of concrete and the corrosion of steel reinforcements and rebar. Fortunately, epoxy concrete crack injection can address many of these concerns in structures exhibiting signs of such issues. Employing a proficient concrete repair team can frequently circumvent the need for a complete teardown.

SealBoss Epoxy Resins

SealBoss Epoxy Crack Injection resins for structural crack repairs conform to ASTM C881 specifications, with appropriate viscosities for the crack widths. The bond strength of epoxy to clean concrete is greater than the tensile strength of concrete itself.

Wider cracks may require a higher viscosity epoxy, small cracks a lower viscosity injection resin. Depending on the requirements, viscosities may range from approximately 150 to 600 cps at room temperature.

SealBoss Epoxy Crack Injection concrete repair can be performed with SealBoss Epoxy Cartridge Systems or SealBoss epoxy bulk resins using air guns, hand-actuated delivery systems, or dual-component injection electric or air-driven pumps.

Prior to repair, the structure must be carefully examined to establish that epoxy crack injection is indeed the correct method to regain the desired structural integrity. The cause of cracking must be determined. Cracks must be identified and the allowable crack width needs to be established. The width of cracks can be measured by using crack gauge cards. In some instances it may be recommended to measure the expansion and contraction cycles of a crack. To determine the depth and cause of cracking, core samples can be taken and examined by petrographic and chemical testing. In addition, nondestructive testing (NDT) ultrasonic pulse velocity can be used to measure the depth of cracks.

Once it has been established that epoxy concrete crack injection is the chosen method of repair, the SealBoss Epoxy Injection System can be utilized to restore the structural integrity of the concrete.

SealBoss ® Surface Mount Injection Ports

Surface-mounted injection ports are typically adequate for injecting most cracks. However, badly deteriorated concrete or higher injection pressures may require the use of drill-in or hammer-in plastic ports or even mechanical packers. Surface ports, aka plastic tubing ports, are glued on the surface over the open cracks using SealBoss epoxy paste adhesive. The injection ports are typically installed at a spacing that is equal to or slightly narrower than the depth of the crack. Hairline cracks require closer spacing than wider cracks.

Wire brushing and vacuuming the crack surface along the crack is often sufficient for surface preparation. In areas of badly deteriorated concrete, pressure washing, grinding, and V-grooving may be specified.

After the surface has been cleaned, surface ports are installed. Sealboss 4500 crack-sealer epoxy paste will be used as surface port adhesive and be applied on the face of the crack between and around the ports.

Once the injection ports are installed, Sealboss 4500 crack-sealer epoxy paste is applied on the face of the crack between and around the ports. To contain the epoxy resin in the crack until it hardens, it is a good practice to seal cracks on all sides of the substrate if possible.

Begin the Epoxy Crack Injection at the Point of the Structure

As soon as the epoxy appears at the next higher port, the current port is capped and the injection is continued from the next port. Multi port injection may be used in most epoxy injection environments. Typical injection pressures are between 50 to 100 psi (3 to 6 bars), with very fine cracks requiring pressures of over 200 psi (12 bars).

Epoxy resins are temperature sensitive. At higher temperatures resin viscosity decreases, but reaction time increases. For best performance during application, it is advised to keep the resin at room temperature or slightly above during injection.

After the injection resin has cured, the epoxy paste adhesive is removed from the surface of the concrete.

Quality assurance and control measures include visual observation of the injection process and product consumption, testing the injection equipment for mix ratio, taking core samples and testing repaired cracks using nondestructive testing methods.

Epoxy Injection in Cold Weather

Epoxy Injection
In Cold Weather

Overcoming the Challenges

Cold weather can complicate concrete repair and waterproofing, especially when working with chemical grouts like polyurethane foams, gels and, in this case, epoxy resins. All theses polymer products rely on temperature for proper curing.

Despite an incoming cold front, a mock-up epoxy injection training session had to proceed. With careful preparation and the right tools, such as heat guns to warm resins and surfaces, the team was able to successfully navigate the chilly conditions.

This cold Thursday morning was no exception to the rule. During a mock-up epoxy injection training an impending cold front was on its way toward Oregon and Washington states, resulting in unusually cold temperatures. However, when a crew needs to receive proper technical training on Sealboss Systems, the show must go on.

We Provide Training in All Conditions

A week prior to the training we wanted to make sure that we were prepared so that everybody in attendance could get the most out of the experience. We proactively sent an email to the contractor requesting that they provide the ancillary items necessary to make the training as efficient and effective as possible.

One of the items requested was a focused source of heat in the way of a heat gun. We were very pleased to see that they were prepared with two heat guns which enabled them to speed up the setting process for the crack seal paste. When chemistry is at play, temperature is a very important factor. In almost all cases, heat will speed up reactions between different chemicals.

In cold weather it is critical to precondition the epoxy resins to room temperature prior to use. Epoxy resins may not react below 35-45°F, but will begin to cure again once the temperature rises. A heat gun can be used to warm up the concrete surface prior to installing surface mounted ports and to increase the temperature of the installed epoxy adhesive to approximately 100°F or 40°C to initiate the exothermic reaction and speed up the cure time. Take care to avoid heating the surface or epoxy to over 130°F or 55°C .

While there are many things out of everyone’s control such as the weather, those things that are in our grasp ought to be executed to the best of everyone’s ability thanks to the preparedness from all members involved with this session, the team was able to benefit from and learn the basics as it relates to structural epoxy injection all the way from port setting to clean out of the pump.

Please inquire about training opportunities with your local SealBoss representative.

We are standing by to do what we can to make sure your teams have the requisite knowledge to be successful when it comes to using SealBoss Systems.

Below Grade Waterproofing

Below Grade Waterproofing: Innovative Solutions for Complex Challenges

In the field of construction and building maintenance, below-grade waterproofing poses distinct challenges, particularly when addressing sensitive areas where direct access to the source of leakage is limited, and traditional crack injection methods for waterproofing are not feasible.

A recent case involving a below grade mechanical room with water intrusion issues highlights the innovative approaches and solutions available in today’s construction industry.

Polyurethane Polymer Gel and Foam Injection are effective methods to seal areas that are not easily accessible. With direct and indirect chemical grout delivery methods available, a wide array of below grade waterproofing problems can be resolved.

In this specific case grout injection lances were the delivery method of choice to combine waterproofing techniques such as soil permeation and consolidation grouting and curtain injection grouting to seal a subterranean mechanical room of a hospital.

Below Grade Waterproofing
Using Injection Lances and Polymer Gel

The Challenge: Water Intrusion in a Below Grade Mechanical Room

A mechanical room located below grade was experiencing water intrusion through shrinkage cracks and cold joints. The complexity of the situation was heightened by the fact that the problem could not be addressed from the negative side (inside the mechanical room) due to the placement of conduit and utility pipes. This scenario is not uncommon in below grade waterproofing projects, where access and space constraints often limit traditional repair methods.

Seeking Expert Solutions

In response to this challenge, the engineer overseeing the project reached out to SealBoss, a renowned name in the field of waterproofing and chemical grout injection solutions. SealBoss proposed a soil permeation and consolidation grouting and curtain injection grouting solution using SealBoss FlexGel hydrophilic polyurethane polymer leak sealing foam gel, a method well suited for this complex below grade waterproofing scenario.

The Process – Soil Permeation Injection and Consolidation Grouting with Injection Lances

Once the proposal was approved by all parties involved, the injection process began. The first step involved drilling cores to confirm the layout of below grade structures. During this phase, an unexpected utility bay was discovered, necessitating a modification in the layout of injection points to accommodate these below grade structures.

Installation and Injection Techniques

The installation process involved driving ½” soil injection lances into the core holes and installing female couplers to work with the custom applicator built by the contractor.

SealBoss Grout Injection Lances for soil permeation and consolidation grouting and curtain injection grouting.

This step was crucial for ensuring that the SealBoss FlexGel would be injected precisely where needed. Before the injection of FlexGel, each hole was initially flooded with water using a SealBoss IP495 Pump, specifically dedicated for water injection. This flooding was essential to suspend the strata below and prepare it for the FlexGel injection.

FlexGel Injection: Creating a Waterproof Barrier

Each hole received an initial injection of 3 gallons of water, followed by 1 gallon of FlexGel neat out of a separate dedicated SealBoss IP495 polymer injection pump. A final injection of up to 1 gallon of water through the designated water pump was then administered. During the FlexGel injection, the lance was lifted to create a vertical curtain, effectively wrapping around the found utility bay. Additional material was pumped below the elevation of the bay on either side to flood the cavity between the utility bay and the exterior of the mechanical room, creating a comprehensive waterproof barrier.

Results and Follow-Up

The initial injections were completed within a few hours, but additional cores had to be made to proceed further. A week after the installation, the area experienced heavy rains for three days. The hospital maintenance staff reported that the leak had subsided, marking a successful application of below grade waterproofing using the Curtain/Blanket Injection method with FlexGel.

Conclusion: Below Grade Waterproofing Success

This case study exemplifies the effectiveness of innovative below grade waterproofing techniques in addressing complex water intrusion issues. The use of FlexGel Hydrophilic gel in a Curtain/Blanket Injection method proved to be an efficient solution for a challenging situation, highlighting the importance of choosing the right approach and materials in below grade waterproofing projects. As the construction industry continues to evolve, solutions like these offer hope and reassurance for tackling even the most daunting waterproofing challenges.

Concrete Crack Injection – Polyurethane

Concrete Crack Injection Polyurethane

Introduction:

Maintaining the structural integrity and aesthetic appeal of concrete constructions is crucial for ensuring their long-term durability and functionality. Water intrusion, often through leaking cracks, poses a persistent challenge that can lead to structural erosion, aesthetic damage, and costly repairs if not addressed effectively.

Leaking concrete cracks are a common issue across various types of infrastructure, from residential foundations to industrial facilities and public spaces. Repairing these cracks requires advanced techniques that not only stop water infiltration but also reinforce the structural resilience of the affected area.

Concrete Crack Injection using Polyurethane (PUR) Water Stop Foam Injection is a cutting-edge, economical solution that provides a permanent seal for leaking cracks. Renowned for its versatility and efficiency, this method effectively addresses a wide range of water damage issues, including structural weakening, rust stains, and efflorescence buildup.

In this article, we explore the PUR Water Stop Foam Injection process, highlighting its procedure, applications, and advantages. By adopting this innovative technique, engineers and contractors can maintain the integrity of concrete structures, safeguarding them from further damage while extending their service life against the forces of nature.

How to Seal Leaking Concrete Cracks with PUR Water Stop Foam Injection

Zoo Exhibit Crack Repair — The Gorilla Exhibit at Omaha’s Henry Doorley Zoo was closed for renovations and repairs, including the sealing of concrete cracks that had shown signs of water intrusion, structural erosion, and visible stains from rust and efflorescence.

Concrete crack injection with polyurethane foam resin was the choice of repair to resolve water bearing crack leaks. Crack related damages were located at a walkway under a lofted area with multiple windows and decorative shotcrete structures where gorillas could sit and be viewed by people walking through the exhibit.

The cracks were covered in efflorescence could be seen on the walls below the lofted area as well as cracks coming off the cold joints around the precast window framing.

The crack dimensions ranged from hairline to 1/4″ joint seams with varying degrees of water intrusion and active leaks causing heavy efflorescence build up. The roof and lofted area collect and feed water during snow melt and heavy rains.

SealBoss provided an on-site technical representative to consult with the contractor on injection methods using NSF/ANSI 61 Drinking Water Contact Certified injection grout, a high-pressure injection pump and mechanical injection packers.

Concrete Crack Injection Polyurethane – Procedure and Repair Method

Prior to injection, the contractor had to first prep the cracks by removing any efflorescence and dirt build-up from the face of the crack using a wire brush.

Once the cracks were visible an injection plan was established to address the leaks working from the low point up.

Using the SealBoss high pressure concrete crack injection system — hydro-active, hydrophobic polyurethane foam resin, injection packers and polyurethane crack injection pump — hydro-active foam resin is injected into the cracks, expanding on contact with moisture and displacing any water in the process while creating an airtight & watertight seal.

Crack Injection Details

A – Standard Injection Procedure

One side of the lofted area had three significant cracks that resulted in substantial active leaks. The east wall presented larger actively leaking cracks. Further, cracks and cold joints from a precast window frame created an area of leakage that needed to be injected.

In those areas, SealBoss 1/2 inch injection packers were placed according to SealBoss Standard Recommendations, roughly 4” from the crack in ½” holes that were drilled at a 45-degree angle back into the crack. SealBoss 1510 Water Stop Foam was injected until positive refusal of the hydro-active resin was visible from the face of the crack as well as on the exterior side of the wall when a through crack was injected.

Starting with the lowest point of the cracks, SealBoss 1510 Leak Sealing Foam Grout was injected until positive refusal was observed on the interior and exterior of the wall. Due to the temperature of the wall, around 36 degrees Fahrenheit, the contractor was advised to condition the resin to room temperature prior to use as well as adding 15% of SealBoss 1510 Accelerator/Catalyst to compensate for the cooler ambient and substrate temperature — cold temperatures slow down the chemical reaction of the injection grout.

B – Custom Injection Procedure

In some areas, more complex leaking cracks and cold joints had to be sealed, requiring a deviation from standard injection packer placement.

Multiple cracks had developed connecting to a larger initial crack, creating a spider-web crack pattern. Due to the complexity of the crack system and intersections of cracks, the injection procedure was modified from the standard alternating “zipper” pattern typically recommended. Cracks were so close in proximity that packers needed to be strategically ‘custom’ placed to increase the chance for each packer drill hole to successfully intersect with the crack — resulting in a less orderly packer placement pattern.

Starting at the low point of crack, the Water Stop Foam was injected till and foam travel was observed at a distance from the point of injection intersecting into other cracks. This meant that multiple cracks could be addressed from one point of injection without the need for drilling too many injection port holes.

As the resin visibly moved up and out of the face of the crack, injection of that specific crack would be stopped so the resin could react and fully expand creating a seal.

Shortly thereafter, a secondary injection of the same packer was performed to penetrate even deeper into the crack and allow for further continuation of visible vertical foam resin travel.

Cleanup

After all cracks were successfully sealed, the injection packers were removed, and the ½-inch drill holes were patched with hydraulic cement for a clean finish. This step restored the surface integrity and appearance of the repaired areas.
