Pipe Penetration
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.

Elevator Pit Waterproofing and Leak Sealing Case Study

On-Site Elevator Pit Waterproofing Injection Training in Nebraska

SealBoss provided on-site support and training to a contractor performing a leak-sealing repair in the elevator pit of a multi-family housing complex in Nebraska. The elevator pit was plagued by persistent water pooling, leading to efflorescence and progressive erosion of the surrounding walls. – More information on effloresence, click here – Without immediate waterproofing intervention, serious structural damage was inevitable.

Identifying the Problem

The main issue involved water seepage through the cold joints between the floor and the poured-in-place wall. One of the walls was constructed with masonry blocks, highlighting the mix of construction methods used, which further complicated the waterproofing process.

The Solution: Polyurethane Foam Injection

After assessing the site, the SealBoss team recommended using SealBoss 1510 Water Stop Foam, in combination with the P2002 Injection System. This high-performance foam was chosen for its ability to expand and fill voids, creating a watertight seal. Its compatibility with the P2002 system allowed for high-pressure injection, ensuring deep penetration and a more effective seal.

Preparing for Injection

Due to the active status of the elevator, scheduling was critical. The contractor worked closely with the on-site technician to temporarily suspend the elevator’s operation, ensuring safety during the waterproofing process

Since original blueprints of the elevator pit were unavailable, the team first drilled test holes to investigate the nature of the cold joint.

These preliminary holes were flushed with water using the BGUN1500 Hand-Operated Pressure Pump and 13-100AL ½” Aluminum Injection Packers to confirm the flow of material along the joint and clean out the drill holes.

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.

Injection Process

The successful pre-test led to the strategic placement of 13-100 AL injection packers 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 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.

Successful Completion

Upon completing the injection, all cracks and cold joints were successfully sealed. This allowed the elevator to return to service with minimal disruption to the building’s occupants. The project highlighted the effectiveness of SealBoss 1510 Water Stop Foam and the importance of strategic planning and execution in elevator pit waterproofing.

Elevator Pit Waterproofing – Key Takeaways from the Project

The Need for Crack Injection Training

A prominent general contractor, who usually subcontracts such tasks, expressed the need for immediate crack injection training on a specific jobsite. Their primary aim was to acquire the expertise for smaller projects, allowing them to handle leaking crack repair internally on certain timely projects. This proactive approach not only saves time but also ensures that minor issues can be addressed before they escalate.

A Case Study: Water Treatment Tank Crack Sealed

Scope: New Concrete Tank – Water Test Failure – Asses and Seal

The facilities in question comprised three holding cells, separated by two poured-in-place division walls. During a leak test on the outer two tanks, visible cracks were detected. These cracks, deemed non-structural for repair purposes, showed signs of dampness and minor leaks, emphasizing the need for immediate leaking crack repair. Pressure crack injection with a hydrophobic polyurethane expanding water stop foam utilizing an electric injection pump and mechanical injection packers was specified as the method of restoration.

The Repair Process

Materials Used: SealBoss 1570, SealBoss 15x
Additional Tools: SealBoss 13-60S packers, SealBoss 495 Injection Pump, Hammer Drill w/ 12” x ½” bit, PPE

For training purposes, a weeping crack was chosen for repair. This crack, though narrow, spanned about 10 feet in height and meandered across the wall. Given that the newly constructed wall was 14 inches thick, the repair strategy involved guiding the team to drill 5 to 7 inches out from the crack. The drilling was done at a 45-degree angle, aiming back towards the crack, employing the crack stitch method.

Depth of Intersection: The further the drill hole is from the crack, the deeper it will intersect the crack within the structure. This results in a more profound point of injection.

Considerations for Thicker Structures: A deeper injection point is often preferred in thicker structures. However, the length and reach of the drill bit play a crucial role in determining the optimal distance for the drill hole.

Avoiding Dead-End Drill Holes: A drill hole that misses the crack won’t facilitate the injection of the chemical grout into the structure. Such holes are termed “dead-end drill holes” and are ineffective for the purpose of grout injection.

In summary, while determining the spacing of drill holes, it is vital to balance the desired depth of injection with the capabilities of your drilling equipment to ensure effective grout injection.

To ensure precision, the placement was set parallel to the fissure. A 0.5-inch masonry bit, attached to a hammer drill, was used for the drilling process. Once the clean, crack-intersecting holes were established, SealBoss 13-60S heavy duty steel injection packers were installed.

The repair commenced from the bottom, progressing upwards. The SealBoss 495 injection pump, paired with the SealBoss 1570 NSF/ANSI/CAN 61 drinking water contact certified chemical grout, was used for the leaking crack repair. As the repair proceeded, water and material were observed exiting the substrate. This was a positive sign, indicating effective penetration and successful stopping of the water penetration and sealing of the crack.

Final Thoughts

Leaking crack repair is an essential aspect of maintaining the structural integrity of buildings and facilities. With the right knowledge, tools, and materials, such as those provided by SealBoss Corp., even the most challenging cracks can be effectively addressed.
