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.

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.

Addressing Manhole Damages and Blockages through Inspections and Repairs

Mitigating Infiltration and Inflow (I/I) in Manholes

Manholes are frequently subjected to I/I, which manifests as infiltration through cracks and joints, and inflow of groundwater. These occurrences can significantly elevate treatment costs and contribute to environmental pollution. Furthermore, they may trigger soil and groundwater contamination, sinkholes, and damage to roads and structures.

To prevent and correct these issues, it is crucial to conduct regular inspections and necessary repairs on manholes.

SealBoss provides a selection of cost-effective systems designed to repair manholes, successfully addressing typical and common forms of damage.

If left untreated, deteriorating and leaking manholes can result in substantial, highly expensive damage to both the environment and infrastructure.

Understanding Sanitary Sewer Overflows (SSOs)

Sanitary sewer overflows (SSOs) represent a pressing environmental and public health issue. These overflows, saturated with untreated sewage, act as conduits for bacteria, viruses, and other pathogens.

At times, sanitary sewers may inadvertently discharge untreated sewage, leading to what’s termed as an SSO. Such overflows can not only taint our water sources, resulting in significant water quality degradation but also backflow into residential areas. This not only damages property but also poses a substantial health risk to the public.

Factors Leading to SSOs:

Blockages in the sewer lines
Ruptures or breaks in the sewer lines
Structural defects that permit storm water and groundwater to inundate the system
Power outages affecting the sewage system’s operations.
Flaws in the sewer system’s design
Acts of vandalism disrupting the system

According to data from the Environmental Protection Agency (EPA) as of September 2023, it’s estimated that the U.S. experiences between 23,000 to 75,000 SSO incidents annually. This figure excludes sewage backups into buildings, underscoring the gravity of the issue.

Identifying Common Manhole Failure Causes

Several common causes of manhole failure include:

Infiltration via precast joints
Leakage from precast manhole rings
Groundwater intrusion through cracks
Infiltration via mortar joints
Cracks resulting from shifting soil, traffic load, or soil expansion
Fissures due to micro-biological corrosion

Prior to injection, repair wide pipe penetrations using Seal-Oakum
Start injection at the bottom

Adressing Manhole leaks through Precast Manhole Rings / Joints

Follow these steps:

Drill injection holes into the manhole rings approximately every 60 degrees
Install six injection packers. In case of severe leaks, more drill holes/packers may be required
Prior to injection, repair wide pipe penetrations and broad ring joints using Seal-Oakum
Start injecting process from the bottom

Manhole Inspections and Preventive Maintenance – The Key to Longevity

Regular inspection of manholes is crucial to identify issues early and prevent them from escalating. Implementing a preventive maintenance program for manholes can prevent costly repairs and extend their lifespan. Regular cleaning, sealing of cracks, and routine inspections can ensure their proper function and prevent I/I.

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.

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.

SealBoss also offers innovative Cold Joint Seal Systems for use during the construction phase, which can prevent leaks from occurring in the first place. Products like SealBoss Swell-Caulk and the SealBoss Inject-Tube System are ideal for creating watertight “pour-in-place” cold joints.

Fasten Plywood to Pallet: Secure a piece of plywood on top of the pallet to create a flat and mobile surface. This will be the base for building your demonstration box.
Start Building with Blocks:
First Row: Using mortar, begin laying the first row of blocks. Follow the pattern provided in the image for guidance.
Subsequent Rows: For the second and following rows, stagger the blocks such that the 5 ½” side alternates sides in the formation. This can be visualized in the referenced image. Continue this process until the block wall reaches a height of four rows.
Reinforcing with Rebar and Mortar:
Place rebar in the designated cells within the blocks, as indicated in the diagram above.
Fill the open cells with mortar, leaving about 2 inches unfilled at the top. This underfilling is crucial for the demonstration of spall repair products.
Preparing for Demonstration:
After the mortar dries, notch the plywood at the center, halfway down, to a depth of ½ inch. This will create a cross within the wall structure.
Install the plywood with the notch in place.
Fit plexiglass to form triangular sections within the box.
Finally, seal the plexiglass in place using silicone sealant.
