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.

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.

Conclusion

Proper planning, testing, and coordination are indispensable on commercial repair jobsites. This on-site intervention by a SealBoss professional, not only served to rectify a pressing problem but also showcased the company’s commitment to delivering time and cost-effective solutions.

Enhancing Aquarium Maintenance with SealBoss Leak Repair Solutions

SealBoss Aquarium Leak Repair Systems, Training, and Support

Recently, the SealBoss technical team made a significant impact at the State Aquarium in Corpus Christi by addressing persistent leaks in their large saltwater tanks. These leaks, which had previously eluded repair by other contractors, were successfully tackled by a SealBoss technician who provided hands-on training in leak-seal and water stop crack injection techniques.

Utilizing the NSF Drinking Water Contact Certified SealBoss Water Stop Foam and the P2002 Professional Injection Pump, the SealBoss expert equipped the aquarium’s maintenance team with the skills and knowledge needed for effective, ongoing leak management. This training ensures that the team can handle future leak-seal challenges confidently and efficiently.

SealBoss systems are designed not just for one-time fixes but for empowering maintenance crews with the tools and techniques for lasting leak prevention. The comprehensive range of SealBoss injection systems and Pro Kits offers professional-grade solutions, tailored to the unique needs of aquarium maintenance.

Identifying leaks in the aquarium is a straightforward process, thanks to the visible salt deposits that form from evaporated seawater. These deposits, a clear indicator of long-standing leaks, are especially noticeable in the State Aquarium due to its use of water from the Gulf of Mexico. The aquarium’s 6-inch thick acrylic glass and supporting concrete structures, prone to shrinkage and stress cracks over time, are typical areas where SealBoss training focused on.

The SealBoss  1, 2, 3, 45-Degree Injection Guideline was a key part of the training, teaching the team to effectively seal cracks and fissures. This technique, which involves staggered packer placement starting 6 inches from the crack center, proved highly effective under the specific conditions of the State Aquarium. The visible displacement of water and expulsion of chemical grout during the injection process was a clear sign of successful resin penetration, indicating a comprehensive seal of the cracks.

All areas were inspected for leaks and marked for injection. Some cold joints along the tank showed also signs of leaks, so preventative injections along cold/construction joints around the tank were advised.

In addition to addressing visible leaks, the SealBoss team advised preventative measures for potential leak sites, such as cold/construction joints around the tanks.

After the training session, the aquarium’s repair team was well-prepared to develop a comprehensive plan for managing both existing and potential future leaks.

Watertight Pipe Penetration Sealing

Watertight Pipe Penetration Sealing

Guidelines for Pipe Penetration Waterproofing

Introduction

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

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

How to Replace failed Water Stop around existing Pipe Penetrations

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

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

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

Utilizing Multiple Products and Techniques for Pipe Penetration Sealing

Oakum Saturation with Foam Grout

Oakum Soakum Installation

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

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

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

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

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

  • In areas of constant hydrostatic pressures it is often recommended to inject the circumferential void throughout the thickness of the wall using SealBoss 1510 or 1570 Water Stop Foam.

  • With the use of a SealBoss Grout Injection Needle and a low cost HP1500 Ultra Light Hand Gun or a HP 100 Hand Pump, the foam grout can be conveniently placed and injected into the void. Depending on the conditions at the jobsite, the injection can be performed following the ‘Oakum Soakum Procedure’, by penetrating the initial repair with the injection needle and inject SealBoss Water Stop Foam behind it.

  • For small jobs and pipe diameters, and for low cost applications where hand pump and injection needles are not feasible, SealBoss Can-Seal Foam can be used as a lower grade alternative.

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

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

Utility Vault Leak Sealing Repair

Utility Vault Leak Sealing Repair

Utility Vault Leak Sealing Repair

Injection Technology for Utility Vault Repair and Maintenance

Introduction:

Utility vaults, integral components of modern infrastructure, house essential services like electrical and telecommunications equipment. Despite their robust construction, they are prone to leaks, especially at precast joints and pipe penetrations. Neglecting these leaks can lead to operational, safety, and financial challenges. This comprehensive guide delves into the intricacies of utility vault leak sealing repair, emphasizing the application of polyurethane grout for long-lasting solutions.

Advantages of  Polymer Grout Injection for Utility Vault Leak Sealing Repair

Polyurethane grouts stand out for their material longevity and flexibility after curing, accommodating structural shifts and reducing the likelihood of cracks. Economically, it requires fewer reapplications and offers reduced labor costs, making it a cost-effective choice in the long run. Environmentally,  SealBoss’s NSF-certified polyurethane grouts meet stringent public health and safety standards, ensuring minimal impact on the environment.

Acrylate / acrylic gel injection resins offer extreme penetration properties and super low viscosity and are used for permeation and curtain injection while providing a sealing membrane in blow grade structures between the concrete and surrounding soil. 

Utility Vault Leak Sealing Repair

Ensuring Structural Integrity and Operational Efficiency

The Consequences of Ignoring Leaks

Unaddressed leaks in utility vaults can lead to equipment corrosion, failure, or increased maintenance needs, affecting the reliability of utility services. Moreover, water in electrical vaults creates a hazardous environment, increasing the risk of electrical short circuits and posing a safety threat to maintenance staff.

The Solution: Polymer Grout

Polyurethane grout, with various physical properties and reaction profiles, including hydrophobic and hydrophilic formulations, offer highly specialized solutions and a professional approach to sealing leaks in utility vaults permanently. On large and damp concrete walls of damp acrylate / acrylic gel injection may be the application method of choice. 

Polymer grout injection most often outperforms traditional methods like cementitious grouting by accommodating structural movements, active high velocity water flow, and preventing leak reoccurrence.

Sealing General Leaks and Leaking Cracks

Leaks can occur due to a variety of reasons including poor construction, soil movement, and aging materials. Cracks in the walls or floor of the vault can develop over time, leading to water ingress.

Crack Injection Method

Crack injection is a precise technique used to address leaking cracks. This method involves injecting a sealing material, typically a polyurethane (or sometimes epoxy resin), into the cracks to create a waterproof barrier.

Steps for Crack Injection:

  • Identifying and Cleaning the Crack: The first step is to thoroughly inspect the utility vault and identify all the cracks. These cracks need to be cleaned to remove any debris or contaminants.

  • Installing Injection Ports: Small injection ports are then installed along the crack at regular intervals. These ports will serve as entry points for the injection material.

  • Injecting the Resin: The selected resin is then injected into the ports, starting from the lowest port and moving upwards. The resin fills the crack completely, creating a waterproof barrier.

  • Curing and Finishing: Once the injection is complete, the resin is allowed to cure. After curing, the injection ports are removed, and the surface is finished as required.

Sealing Damp Walls with Curtain Injection Technique

Damp wall and water seepage with very fine cracks or no visible cracks. This issue is typically due to water seeping through the walls, which can be a result of groundwater pressure, capillary action and porous substrate.

Curtain injection is an effective method for addressing general leaks and damp walls. It involves creating a waterproof barrier behind or around the leaking area. Curtain injection is performed with SealBoss polyurethane grouts or SealBoss 2400 acrylate/acrylic gel resin.

Steps for Curtain Injection

  • Assessment of the Leaking Area: A thorough assessment is conducted to determine the extent and source of the leaks or dampness.

  • Drilling Injection Holes in Grid Pattern: Holes are drilled into the wall or ceiling at strategic locations to cover the area affected by the leaks or dampness.

  • Injecting the Grout: A low-viscosity polyurethane grout is injected into these holes. The grout travels through the voids and cracks behind the wall or ceiling, forming a curtain-like barrier.

  • Creating the Waterproof Barrier: The grout permeates and creates a curtain or bladder, sealing off the water paths and creating a waterproof barrier.

  • Curing and Inspection: After the injection, the grout is given time to cure. A final inspection is conducted to ensure the effectiveness of the barrier. Curtain injection can often be tested by flooding the area behind the structure.

The Water Migration Problem of Precast Joints and Pipe Penetrations

Precast joints in utility vaults, formed at the junctions between concrete sections, are susceptible to leaks due to cracks, soil shifts or temperature fluctuation caused movement.

Similarly, pipe and conduit penetrations, where utility lines enter the vault, can become leak points. The original sealing around these areas can degrade over time, allowing water to infiltrate the vault.

Repairing Precast Joint Leaks

For precast joint leaks, products like SealBoss 1510 and SealBoss 1570, combined with SealBoss Oakum, offer effective solutions. SealBoss 1570 is a highly flexible polyurethane grout that adapts to movements between concrete sections, while SealBoss Oakum, a special oil-free dry jute rope, helps to seal large and irregular defects when used in combination with the grout.

Installation Guideline

  • Clean and moisten surfaces before applying Oakum
  • Saturate SealBoss Oakum with SealBoss Polyurethane Resin
  • Pack the Oakum into the precast joint and, if necessary, inject additional resin for a complete seal.
  • Allow the material to cure overnight

Addressing Pipe Penetration Leaks

For pipe penetration leaks, a combination of SealBoss Polyurethane grout and SealBoss Oakum can create a durable seal. Soaking SealBoss Oakum in the grout and then packing it around the pipe forms a tightly sealed gasket.

Installation Guideline

This method offers longevity, with the potential to last up to five decades.

Selecting a Qualified Contractor

The effectiveness of the repair largely depends on the skill of the contractor. It is crucial to choose a contractor experienced in applying polymer grout. Look for contractors who have received training from the material manufacturer and have a proven track record in polymer water stop injection and leak sealing projects.

Evaluating Proposals

When reviewing proposals, focus on the detailed scope of work, proposed materials, cost breakdown, project timeline, and references. This due diligence ensures that your investment in utility vault leak sealing is well-placed.

Conclusion

Utility vault leak sealing repair, particularly with polymer grouts and resins, is an essential aspect of maintaining infrastructure integrity. Choosing the right contractor and using quality products like those offered by SealBoss can ensure the longevity and effectiveness of the repairs. By addressing these leaks proactively, you can mitigate operational challenges, ensure safety, and avoid negative economic impacts.
