Sealing Pipe Penetrations in Foundation Wall

Football Team Field House
SealBoss PUR Grout Injection

Sealing Pipe Penetrations in Foundation Wall with Chemical Grout Injection

Location: Sam Houston State University – Huntsville, TX

Project Spotlight: Sam Houston State University Football Field House Renovation

Background:
Sam Houston State University embarked on an ambitious renovation project for its football team’s Field House and Locker Room.

Scope of Work:
The renovation involved the addition of masonry walls and the sealing of old Pipe Penetrations. Contractors were instructed to remove the existing pipe penetrations, seal them with a grout patch, and subsequently drill a ½” hole through the patch. An injection was then carried out behind the grout patch, ensuring a watertight seal, as outlined by the project engineer.

Expertise in Action:
The project contractor enlisted SealBoss to provide hands-on technical guidance for the specified injection process.

Additional Training:
Beyond the specified injection process, the contractor was also trained in alternative repair techniques. This included using SwellCaulk and Oakum to effectively seal off the pipe penetrations.

This collaborative approach and training ensured the project’s success while also expanding the contractor’s repertoire of repair methods.

Sealing Pipe Penetrations in Foundation Wall – Specified Repair Procedure

After ensuring the grout patch was fully set, the contractor drilled a ½” hole directly through its center. Debris from the hole was carefully vacuumed out, and the hole was subsequently flushed using a specially modified water bottle, ensuring a clean, pressured stream. Once thoroughly cleaned, the ½” SealBoss Evolution 13-100AL injection packer was fitted in place.

Utilizing the SealBoss P2002 pump, the SealBoss 1510 Water Stop Foam System was pressure-injected into the void behind the grout patch. This process guaranteed an air and watertight seal, preventing any water seepage through the patch.

Sealing Leaks with Polyurethane Water Stop Foam 1510 | 1570

Sealing Leaks
with
Polyurethane Water Stop Foam

Effectively Sealing Leaks with Single Component Hydrophobic Polyurethane Water Stop Foam Technology

Closed-cell polyurethane water stop foams offer a potent solution for sealing leaks with polyurethane and ensuring the integrity of concrete structures. These advanced hydrophobic polyurethane (PUR) foams are specifically designed to react on contact with water, expanding in volume to effectively fill and seal the affected areas.

Sealing leaks with polyurethane is achieved through the Leak Sealing Pressure Injection process, which employs SealBoss grouts and injection components to force polyurethane resin deep into leaking cracks, joints, voids, fissures, and other defects. This innovative method ensures thorough penetration and coverage, enhancing the overall effectiveness of sealing leaks with polyurethane.

During the injection process, the polyurethane resin reacts rapidly with water, forming a flexible, watertight, and durable seal. This exceptional property of sealing leaks with polyurethane ensures that concrete structures maintain their integrity even under challenging conditions.

Concrete structures with leaks can be permanently repaired using water-activated, water stop polyurethane foams, as well as cutting-edge leak sealing equipment and accessories. For added confidence in the quality and safety of the process, NSF/ANSI certified products are available.

SealBoss Leak Sealing and Structural Concrete Repair and Injection Systems provide a comprehensive solution for addressing practically any water-bearing defect in concrete. By leveraging polyurethane for leak sealing, these advanced systems can tackle issues ranging from hairline cracks to gushing leaks, ensuring the resilience and strength of concrete structures.

Residential Polyurethane Foam Void Fill & Slab Stabilization

Residential Polyurethane Foam Void Fill
& Slab Stabilization

Structure prior to injection

Is Polyurethane Foam Void Fill Quick and Affordable?

Time-Sensitive, Cost Effective, Minimal Invasive

Erosion caused by the movement of water can lead to many structural issues on a residential property. Water can wash away improper fill and undermine the substrate below a slab. This can cause cracking on the slab or on a masonry exterior and lead to structural and cosmetic issues.

The back patio and three season room addition had begun to sink due to improper dirt work and erosion. The goal of the repair was to fill the voids under the structure with a high strength polyurethane void fill foam to reduce or eliminate further water ingress and to provide structural support for the sinking slab and structure.

The project required a quick, time-sensitive , minimal invasive and comparatively low cost solution.

After the injection cured foam was observed as it had emerged from fissures in the surrounding soil during the injection process. Although not a primary objective in this comparatively low cost repair, a slight lift of the structure was achieved.

Structure after injection - Voids are filled and lift of structure observed

System Used

SealBoss 1640 polyurethane void fill and polyjacking foam was pumped through the SLP-2C pneumatic dual component pump, and injected through 5/8 button head Packers for maximum material flow.

Powered by a 4 CFM air compressor, the SLP-2C was able to successfully deliver the 1640 foam below the slab and successfully fill the void and stabilize the slab.

SealBoss’s 1640 is a 4 pound density Cold Foam specially formulated for maximum expansion at ambient temperatures eliminating the need to heat the material or injection lines in many environments. For minimum temperature requirements please consult your SealBoss technician.

The expanding and compressive strength qualities of SealBoss ® 1640 Structural Strength Foam make it a price competitive alternative for the filling of large voids and ‘pockets’. SealBoss ® 1640 Structural Strength Foam can be applied in dry and wet areas. Additional moisture may increase the expansion. The standard mixture expands approximately six times in volume. Job site testing is recommended to determine product suitability.

For best results with Cold Foam Lift & Under Slab Void Fill
Depending on ambient and substrate conditions foam may need to be temperature conditioned prior to use. Please consult with your SealBoss technician for details.

'As we injected under the slab of the corner of the three season room, the decorative masonry column began to creak and pop as the void under the slab was filled with 1640 polyjacking foam.

In addition to the void fill and erosion control application the expansion of the foam achieved a lift of the structure which helped to straighten the bent window frame. Water that was trapped in the windowsill began to run out. We could see the cracks in the masonry visibly shrink as the corner began to lift.

With such a compact and efficient void fill and slab lifting system, we can provide new business opportunities for smaller residential general contractors who want to expand their scope for sidewalk, driveway, patio, pool deck repair.'

Injectable Waterstop for Cold Joints & Construction Joints
Cold joints and construction joints in concrete structures are vulnerable areas for leaking and cracking due to water penetration. Water ingress can lead to reduced structural integrity and other issues including rebar corrosion and expansion cracks, frost and thaw cycle damages and adverse health effects cause by mold and fungus growth.

What is a Cold Joint?
A cold joint is the area that is created during the concrete pouring process when fresh and existing concrete meet. A cold joint is caused by a lack of bonding / cohesion between the old and new concrete. The cold joint is created when the original batch of concrete has begun to set (or is fully cured) before the next fresh batch is added. The two batches do not form a strong bond and create a passageway for water to migrate.

Freezer Floor Crack Repair

Freezer Floor Repair

The addage ‘time is money and money is time’ is no mystery to warehouse operators and owners.

When valuable foods such as meats, seafoods or produce are stored in areas with cold temperatures, floor repairs needs can start to present themselves, especially when ice becomes an issue.

In the freezer department of a food handling facility, the transition threshold between the freezer area and the cold prep area was in jeopardy due to spalling.

Warehouse operators and owners understand how important it is to keep the floors in smooth and navigable condition.

Besides the obvious concerns of safety, hygiene, and aesthetics, pallet jacks may get stuck and damaged, and warehouse forklift wheels take a constant pounding.

Safety is the always the number one concern for the responsible and liable business operators. Pallet jacks and forklifts need to run as smoothly as possible over floors, ramps, and transitions — for the security and safety of the operators and the merchandise.

Forklift tires and other impact related repairs or equipment replacement can be very expensive. When the equipment is rattled and chewed up by damaged concrete floors and ramps the costs add up quickly.

Last, but not least, good hygiene and manageable, clean surfaces are an expected standard in a food product environment.

Something Needed To Be Done

Freezer Floor Crack and Spall Repair with SealBoss QuickFix

SealBoss 6060 QuickFix has the ability to cure in temperatures as low as -20° F / -29° C making it an incredibly resilient and reliable product to repair damaged floors in the harshest conditions.

With a set time of less than 5 minutes at room temperature, a good repair team can return a warehouse floor back to service in the same day, keeping business flowing and the revenue stream healthy.

Warehouse owners do not have the luxury of waiting full shifts to allow for products to cure over the span of several hours but rather need something that can get the job done within half of a working day.

Prior to the repair, SealBoss 6060 QuickFix has to be thoroughly mixed and, when used in colder ambient temperatures, conditioned to room temperature in order to achieve the best results. Properly prepped material is key to ensuring the job goes smoothly, as the final curing of the material happens only within minutes after applying the mixed material.

The spall has to be dry, debris free and uniform in depth, with a minimum of ¾ of an inch. Taking these steps will ensure good adhesion and prevent delamination.

As an example, with this job where the material was used to great success, a blowtorch was applied briefly to the substrate in order to melt and remove any ice, to get rid of excessive moisture and to warm up the general area for good bond and quick cure.

Important: Application should not leave any gaps between substrate and repair. Any entry points for water must be sealed to prevent water from entering. Joints and gaps can be filled with flexible SealBoss 6500 Polyurea Joint Filler.

When used in conjunction with the SealBoss 6500 Polyurea Joint Filler, these two SealBoss QuickFix Line floor repair products provide a 1-2 punch that allows for fast back to service operations.
