How to stop leaks of high hydrostatic pressures with Injection Grouts

Water ingress can cause immediate damages as well as lead to increased project costs and may lead to many other issues down the line.

Water leaks through cracks, joints and voids can be repaired with cost effective and highly successful injection systems, utilizing chemical grouts such as multi component acrylate gels and single component polyurethane resins.

Appropriately engineered resin injection systems do not not only seal leaks in the structure itself, but can transform loose sands behind the structure to a confined consistency similar to sandstone, and consolidate gravel to a bonded conglomerate.

Example: SealBoss Acrylates Used to Seal Leaks in Tunnel

What are Acrylate Gels?

Acrylate Gels, also known as Acrylic Gels, are very flexible, super low viscosity — similar to water — hydrophilic gels designed for non-structural injections of cracks, joints, voids, and used for grid, curtain, bladder injection and as sealant in the injection tube system.

Due to their extremely low viscosity and low surface tension, polyacrylate gels offer superior penetration properties. Acrylates are gel time adjustable to meet jobsite conditions such as temperature and injection distance.

Acrylic gels are used to waterproof leaks and create a compression seal due to their hydrophilic swelling behavior when in contact with water.

Acrylate injection equipment can easily be cleaned with water.

SealBoss provides a wide range of products to control water ingress into underground mining works, tunnels and many other commercial structures with leakage issues. We supply materials for waterproofing, consolidation, sealing, crack and joint repair, bonding and cavity filling.

Understanding Retaining Wall Repair:

Polyurethane vs. Epoxy Injection Methods

Retaining walls play a pivotal role in infrastructure and landscape, offering both functional support and aesthetic appeal. These structures, while robust, are susceptible to environmental factors and age related weakening that can lead to cracks, spalls, water leakage, or other forms of structural damage.

Addressing these issues promptly and effectively is crucial to ensure the longevity and safety of the wall. In the realm of deep penetrating, effective sealing and high strength structural retaining wall repairs, two methods have emerged as frontrunners: Polyurethane and Epoxy injection.

This overview explores the intricacies of both methods, comparing their advantages, applications, and effectiveness to guide you in making an informed decision for your retaining wall repair needs.

Retaining Wall Repair
with Leak Sealing Polyurethane Water Stop Foam Injection

Retaining walls serve as crucial components in construction projects, especially when dealing with slopes or elevated terrains. Their primary function is to combat soil erosion and bolster the stability of structures by resisting the pressures of soil and water. Yet, like all structures, retaining walls are prone to wear and tear, often manifesting as water leakage and subsequent erosion.

Enter polyurethane injection, a game-changer in the realm of retaining wall repairs. This method stands out not only for its efficacy but also for its cost-efficiency. Unlike traditional repair methods that might involve extensive excavation, the use of heavy machinery, or prolonged construction periods, polyurethane injection offers a swift and minimal-disruption solution. The essence of this method lies in the foam grout injected, which forms a resilient waterproof barrier, crucial for walls constantly exposed to moisture and hydrostatic pressure.

At its core, polyurethane injection foam is engineered to expand upon water contact. Typically, this foam is introduced into cracks or voids within a structure. Upon encountering water, a chemical reaction is triggered, causing the foam to swell and occupy the space. This unique expanding property is invaluable for tasks like leak sealing, ensuring that the foam aptly fills gaps and halts further water penetration.

The combination of low viscosity, fast expansion and curing, flexibility, good chemical resistance and adhesion, make polyurethane injection foam grout an effective choice for leak seal and water stop injection applications.

Here are some advantages of using PUR foam for stopping water migration through retaining walls:

Cost-effective — Polyurethane injection is a cost-effective solution for repairing a leaking retaining wall. It requires less labor, time, and materials compared to traditional methods of repair, such as excavation and replacement
Water Stop Leak Sealing and Waterproofing — The injected polyurethane resin expands on contact with moisture and creates a waterproof compression seal that prevents further water infiltration into the retaining wall
Minimal-Invasive — Polyurethane injection requires minimal disruption to the surrounding area, making it a convenient solution for homeowners and business owners. It does not require excavation, heavy machinery, or lengthy construction timelines
Quick — Polyurethane injection can be completed quickly compared to traditional methods, minimizing the time that the retaining wall is out of commission and minimizing disruptions to daily activities
Durable — The injected polyurethane resin creates a strong and flexible bond with the concrete surface, making it a durable and long-lasting solution for sealing a leaking retaining wall

Summary

Polyurethane injection is a cost-effective, waterproof, minimal-invasive, quick, durable, versatile, and eco-friendly solution for sealing a leaking retaining wall. If you are facing a leaking retaining wall, consider using this method for an efficient and effective repair solution.

Retaining Wall Repair
with Epoxy Resin Injection For Structural Strength

Retaining walls play an indispensable role in both landscape and infrastructure, acting as bulwarks against soil erosion and providing essential structural support. Yet, like all structures, they are vulnerable to the elements, facing challenges like natural degradation, water-induced damage, and the relentless pressure from the soil. Over time, these factors can result in cracks, voids, and other structural concerns. Left unaddressed, these issues can jeopardize the wall’s stability and safety. This is where epoxy resin injection comes into play, offering a robust solution to restore and reinforce a retaining wall’s strength.

Here is a closer look at the benefits of using epoxy resin injection for retaining wall reinforcement:

Structural Strength Repair — Retaining walls can lose their structural strength due to natural wear and tear, crack development, water damage, and soil pressure. Epoxy resin injection can fill and reinforce the damaged areas, restoring the retaining wall’s strength and stability. Epoxy resin, known for its high compressive and tensile strength, can fortify damaged areas, resisting both compressive and tensile forces. Its ability to prevent crack propagation and bear significant pressures and loads makes it a prime choice for restoring walls facing soil and water pressures
Durability — Epoxy resin injection is a durable solution for retaining wall repair. Epoxy resin is resistant to water, many chemicals, and typical ambient heat. It also resists wear and tear, making it a long-lasting solution that can withstand the test of time
Cost-effectiveness — Opting for epoxy resin injection can be a financially savvy decision. When compared to the steep costs associated with wall replacement—which often involves excavation, demolition, and rebuilding—epoxy injection emerges as a cost-effective alternative
Minimal-Invasive — Epoxy resin injection is a minimal-invasive solution for repairing retaining walls. It does not require excavation, heavy machinery, or lengthy construction timelines, minimizing the disturbance to the surrounding area
Quick — Time is of the essence in repair projects. Epoxy injection offers a faster turnaround than many traditional methods, ensuring the retaining wall is swiftly restored to functionality, with minimal disruption to daily routines

Summary

Epoxy resin injection is a reliable and efficient solution for structural retaining wall repair, offering a range of advantages such as durability, high compressive and tensile strength, cost-effectiveness, and minimal-invasiveness.

For any structural repair project, it is highly recommended to seek guidance from a professional engineer to assess the suitability of epoxy injection. Additionally, it is important to hire a skilled and experienced epoxy injection contractor who can perform the repair in accordance with the specifications. This ensures that the repair is conducted safely and effectively, and that the structure is restored to its optimal condition. It is crucial to prioritize safety and quality when it comes to structural repairs — expert advice and hiring competent professionals can help to achieve these goals.

Conclusion

Retaining Wall Repair – Polyurethane or Epoxy Injection

Polyurethane foam injection can be applied effectively in a wet environment where active water leaks are present. When the foam is injected, it expands and creates a water-resistant barrier that forms a permanent, flexible or semi-flexible seal upon contact with water. In most cases, there is no need to surface seal cracks before injecting the foam. Injection packers can be installed in wet environments and injection is not impacted by active water flow. While water-bearing cracks can lead to structure deterioration and erosion over time, they often do not compromise the structural integrity of the building if recognized early and sealed promptly
While structural epoxy injection can effectively restore a retaining wall’s strength and integrity, it is most effective in a dry environment. Epoxy is not well-suited to stop active water leaks. The injection area requires more preparation work, and it is recommended to surface seal cracks before injecting the epoxy. Surface ports do not adhere well in very wet environments. This repair method is more time-consuming and labor-intensive compared to polyurethane foam injection, and it can be more expensive

In summary, both polyurethane foam injection and structural epoxy injection are effective repair methods for retaining walls. Polyurethane foam injection is a highly effective method for preventing water infiltration, stopping active water flow, and efficiently and permanently sealing cracks. Structural epoxy injection is most suitable for application in environments that are not actively leaking and require additional support for significant structural damage in the wall.

Ultimately, the choice of injection repair method will depend on the specific project requirements.

It is always recommended to consult with a qualified professional to determine the best approach for your retaining wall repair needs.

Retaining Wall Crack Injection Repair Guide

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.

Concrete Crack Injection – Polyurethane

Concrete Crack Injection Polyurethane

Introduction:

Maintaining the design integrity of concrete structures is paramount, particularly when it comes to preventing water intrusion and ensuring long-term durability.

Leaking concrete cracks pose a significant challenge across various infrastructures, necessitating advanced and reliable repair solutions.

Concrete Crack Injection with Polyurethane (PUR) Water Stop Foam Injection is a modern and economical approach designed to effectively seal leaking concrete cracks permanently. Chosen for its efficacy and adaptability, this method addresses a wide range of issues associated with water damage, including structural erosion and the presence of efflorescence.

Highlighting the procedure and it’s benefits, this article is an introduction to leveraging PUR Water Stop Foam Injection to maintain and enhance the integrity of concrete constructions, ensuring long-term protection against the elements.

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 the cracks were successfully injected, the injection ports were removed, and a hydraulic cement patch was used to patch the ½” dill holes.

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.

Elevator Pit Waterproofing and Leak Sealing Repair Case Study

On-Site Elevator Pit Waterproofing Injection Training in Nebraska

SealBoss provided on-site guidance to a contractor tackling an injection leak-seal repair in an elevator pit of a multi-family housing complex.

This elevator pit had become problematic, with persistent water pooling leading to efflorescence – more information on effloresence here – and progressive erosion of the in-situ walls. Without timely elevator pit waterproofing, serious structural issues were imminent.

The task at hand was to counteract and stop the water seepage from the cold joints of the floor and the poured-in-place wall. Notably, one wall was constructed using masonry blocks, illustrating the blend of construction methods employed.

An initial assessment indicated that the SealBoss 1510 Water Stop Foam, paired with the P2002 Injection System, was an optimal elevator pit waterproofing solution. This foam, tailor-made to stop leaks by filling gaps and cracks, would serve as a time-efficient and cost-effective solution. Its compatibility with the P2002 system allows for high-pressure application, enabling deep penetration and a more robust seal.

Operational schedules, given the active elevator, were pivotal. This involved liaising with the responsible technician on-site to temporarily suspend the elevator’s operations, thereby ensuring the contractor’s safety while working beneath the elevator car.

Without original blueprints of the elevator pit, the nature of the cold joint was uncertain. To decipher it, test holes were drilled, and a preliminary injection of water was executed using the BGUN1500 hand-operated pressure pump and 13-100AL ½” Aluminum Injection Packers.

The pre-injection served a dual purpose. Besides verifying travel along the joint, it also functioned as a cleaning mechanism, flushing out the drill hole and priming the crack for the injection of the hydro-active 1510 Water Stop Foam.

Driven by the promising pre-test, 13-100 AL injection packers were strategically positioned with approximately 18” spacing. These packers were then drilled around 4” – 6” from the wall through the floor, following the well-established 1, 2, 3, 45-Degree Guideline drilling method. In the case of corners, packers were placed about 8” from the corner point and drilled directly into the corner at a 45-degree angle through the floor. Additional packers were set 8” from the adjacent wall and 4” – 6” from the wall face where the joint would be injected.

Once the packers were firmly installed, the injection process began. There was an immediate take of material and travel. The off-gassing from the chemical reaction was noticeably visible several feet from the injection point, signaling the foam’s effectiveness. Shortly thereafter, the cold joint started to resist the resin, indicating the commencement of the curing process. As the foam reacted and solidified, smaller shrinkage cracks became apparent.

All cracks and cold joints were injected and efficiently sealed, preventing any further water intrusion. The successful completion of the task allowed the elevator to be safely returned to service, ensuring minimal disruption to the building’s occupants.

Elevator Pit Waterproofing Accomplished

This endeavor showcases the expertise of SealBoss in effectively managing water leakages in complex environments. It also demonstrates how the proper application of specialized materials, such as SealBoss 1510 Water Stop Foam, can ensure durable and reliable results. The project underscores the importance of adequate planning and coordination in such operations.

Additionally, this experience emphasizes the crucial role of pre-injection tests in ensuring the success of the actual repair. By confirming travel along the joint and cleansing the drill hole, the process ensured a successful application of the Water Stop Foam System.
