SealBoss Curtain Injection Pattern

Curtain / Bladder Injection - Curtain Wall Grouting Method

Water intrusion is a persistent challenge for below-grade concrete structures, where traditional patching and surface sealers often fall short. The failures of these surface-applied remedies—such as patches, liquid sealers, and membrane applications—stem from their inability to address the root causes of leaks. These methods provide only temporary relief, leaving structures vulnerable to recurring hydrostatic pressure and ongoing water damage.

Curtain wall grouting, including advanced techniques like curtain and bladder injections, offers a reliable, long-term solution to these challenges. Unlike surface treatments, these methods work by creating a robust waterproof membrane and water barrier behind the structure. This approach not only seals cracks and cold joints from within but also fortifies the structure against future water intrusion.

By injecting specialized grouts through the structure to form a protective layer on the positive side, curtain injection ensures a comprehensive and lasting seal. Whether applied through stage grouting or other targeted injection methods, this professional approach delivers durable protection, minimizing service interruptions and maximizing cost-effectiveness in the long run.

Curtain / Bladder Injection is the Reliable Way to Waterproof Your Below Grade Concrete Structure

Why Patches and Liquid Sealers Often Don’t Stand the Test of Time

Experiencing the frustration of failing patches and paint applications on damp, actively leaking, below-grade structures is something many of us can relate to.

These are typically failed attempts to block hydrostatic water intrusion using surface-applied remedies that serve as temporary solutions at best.

Interior patches and membrane applications, while seemingly addressing the problem, often don’t tackle the root cause and rarely provide a lasting waterproofing resolution.

A Professional Approach to Curtain Injection:

Sealing Cracks Permanently and Establishing a Waterproof Membrane and Water Barrier behind the Structure

Water leakage via cold joints, cracks, and other irregularities in concrete can frequently only be effectively and permanently sealed using advanced injection techniques, such as curtain, bladder, and stage grouting injection methods.

The SealBoss Injection Product offers a professional solution to these issues, filling and sealing the cracks from the inside out. This product is injected through the structure, forming a membrane on the structure’s positive side, thus providing a more effective and lasting waterproofing solution.

The Art of Stage Grouting Technique

In complex grouting scenarios, the stage grouting technique is often the favored approach. This process entails a strategic series of injections carried out in a staged manner, utilizing lower volumes of product in each application.

Each stage of this meticulous process is allowed sufficient time to react, allowing the grout to solidify and establish a natural barrier before proceeding with the subsequent stage of grouting. This carefully phased and controlled deployment not only elevates the overall efficacy of the grouting operation but also ensures thorough and consistent coverage along the exterior of the wall.

Comparative Cost Analysis of Injection Grouting Sealing Methods

Understanding the financial impact of various sealing techniques is essential for making cost-effective decisions. Below is a comparison.

Crack Injection

Direct Costs: Moderate for materials and labor, product is injected directly into the cracks, joints, and voids. Low for equipment.
Indirect Costs: Minimal, as the method is fastest and causes little service interruption.

Curtain Grouting

Direct Costs: Higher for materials and labor, product is injected through the structure into the substrate behind, which results in higher material consumption. Packers are set in distinctive patterns. Moderate for equipment.
Indirect Costs: Higher, due to the lengthier process of preparation and product pumping, which can lead to more significant service disruptions.

Water Infiltration Costs & Injection Grouting | SealBoss

Water infiltration costs rise quickly when active leaks are not sealed at the source

Small leaks rarely stay small. Once water finds a path through concrete, every storm, pressure cycle, and wet-dry event can add cost — cleanup, downtime, damage, liability, and eventually structural repair.

Water infiltration is not just a stain on a wall or a puddle on a floor. It is evidence of an open pathway through the structure.

For facility managers, property owners, engineers, and repair contractors, the priority is simple: identify the water path and stop it before the damage spreads. Surface patches may hide the symptom, but professional leak-seal injection grouting is designed to seal the route water is actually using.

SealBoss leak-seal systems are built for that purpose: water stop foams, flexible polyurethane resins, hydrophilic gels, acrylate gels, pumps, packers, ports, oakum systems, pipe kits, and technical support — all focused on stopping active water intrusion at the source.

What Water Infiltration Can Cost

Water Infiltration Costs: What Building Owners May Pay

The cost of water infiltration is not measured only by the crack. It is measured by how far the water has traveled and what it has reached.

Condition / ScopeTypical Cost RangeWhat It Usually Includes
Single active crack or joint$300–$1,800 per crackInterior polyurethane injection of one leaking wall crack, cold joint, or construction joint without excavation
Multiple cracks or larger leak area$2,000–$7,000 per projectSeveral injected cracks, a leaking wall section, floor-to-wall joint, slab area, pit, vault, or below-grade structure
Water-damage cleanup after spreading$4.00–$8.00 per sq ftDrying, demolition, cleanup, flooring replacement, finish repair, contents handling, and restoration work
Severe long-term infiltration$20,000+Corrosion-related damage, concrete spalling, reinforcing steel exposure, structural repair, or partial removal and replacement
Major structural removal and replacement$100–$300 per sq ftExtensive demolition, concrete replacement, reinforcement repair, and reconstruction where deterioration has advanced

Cost note: These are general industry-average ranges compiled from published concrete-repair, crack-injection, and commercial water-damage restoration cost guides. Actual costs vary by site conditions, access, water pressure, region, severity, and project requirements.

The lesson is straightforward: the cheapest leak is usually the one repaired before water reaches finishes, flooring, equipment, tenants, inventory, or reinforcing steel.

The Real Problem Is the Water Path

Concrete is strong, but it is not automatically watertight.

Water can enter through shrinkage cracks, cold joints, construction joints, pipe penetrations, honeycombed concrete, slab joints, wall cracks, tie holes, and voids. Below-grade structures are especially vulnerable because hydrostatic pressure can push water through even small openings.

Once water has a connected pathway, it will continue to use it.

That is why the visible leak can be misleading. The water may appear at one location, but the entry point or travel path may be inside the wall, beneath the slab, around a penetration, or along a joint.

A lasting repair must address the path, not just the wet surface.

Why Surface Patches Often Fail

Many leak repairs fail because they are applied to the side where the water appears, not the side where the pressure originates.

In below-grade structures, water pressure usually comes from the positive side — the soil side, exterior side, or water-bearing side of the structure. The repair crew often works from the negative side — the interior face of the wall, slab, pit, tunnel, or vault.

That creates the classic patch-and-repeat problem:

  • The stain is painted.
  • The joint is patched.
  • The surface is coated.
  • The area looks dry for a while.
  • Water pressure returns.
  • The leak reappears through the same path or nearby.

A surface repair may improve appearance, but it does not necessarily fill the crack, joint, void, or penetration through the structure. If the water path remains open, the cost cycle continues.

SealBoss Injection Grouting: Stop the Leak Where It Lives

SealBoss leak-seal injection grouting places the repair material directly into the pathway used by the water.

Depending on the condition, trained contractors can inject water-reactive polyurethane foam, flexible resin, hydrophilic gel, acrylate gel, or related leak-seal materials into cracks, joints, voids, and penetrations.

The purpose is not to cover the leak.

The purpose is to fill and seal the route water has created.

That is the difference between cosmetic waterproofing and active leak sealing.

Matching the SealBoss System to the Jobsite Condition

Different leaks require different materials. A high-volume gusher is not the same as a hairline weep. A moving joint is not the same as a static crack. A pipe penetration is not the same as a curtain-grouting condition.

Product selection matters. Viscosity, reaction speed, expansion, flexibility, moisture response, and delivery method all affect the outcome.

SealBoss supports contractors with a full system approach: leak-seal materials, injection pumps, mechanical packers, ports, hoses, couplers, oakum, pipe kits, accessories, field guidance, and training resources.

Product, Pump, Packer, Technique

A successful injection repair is not only about the resin. It is about the complete system.

Product

The grout or resin must match the leak type, crack size, water flow, movement, moisture condition, and exposure requirement.

Pump

The pump must deliver material at the right pressure and volume for the structure and leak condition.

Packer / Port

The packer or port must provide a reliable injection point into the crack, joint, or void.

Technique

Drilling angle, spacing, injection sequence, pressure control, and material consumption all influence the final seal.

This is where professional know-how makes the difference. SealBoss products are designed to work as part of a repair system, not as isolated materials.

The Cost Problem With “Almost Fixed”

A leak that returns is not fixed. It is deferred.

The most expensive repair is often the one that looked cheapest at first but had to be repeated. Patch-and-repeat work creates callbacks, continued water damage, tenant complaints, downtime, cleanup costs, and owner frustration.

Contractors who use injection grouting can change the conversation from “patch this spot” to “seal the leak path.”

That is a stronger value proposition for the owner and a better technical solution for the structure.

Common Leak-Seal Applications

SealBoss leak-seal injection grouting systems are commonly used for active water intrusion in:

  • Below-grade foundation walls
  • Floor-to-wall joints
  • Cold joints and construction joints
  • Shrinkage cracks and structural cracks
  • Elevator pits
  • Parking garages
  • Utility vaults and manholes
  • Tunnels and dams
  • Water tanks and wastewater structures
  • Pipe penetrations
  • Honeycombed concrete
  • Seawalls and marine structures
  • Curtain-grouting and permeation-grouting conditions
  • Soil and void conditions related to water movement

Each project should be evaluated based on water pressure, access, crack width, movement, substrate condition, and service environment.

Stop the Water Before the Cost Multiplies

Water infiltration rarely gets cheaper with time. Once water is moving through a structure, it can turn a small repair into a much larger building expense.

SealBoss leak-seal injection grouting systems help contractors and facility professionals stop active leaks at the source with professional-grade water stop foams, flexible resins, gels, pumps, packers, accessories, and technical support.

Tunnel Water Stop Injection Leak Repair Overview 

Tunnels, essential to modern infrastructure, vary in design and function but share a common challenge—water intrusion. Below is an overview of the tunnel types most susceptible to leaks and the potential risks they face:

  • Utility Tunnels – These tunnels house essential systems such as electrical wiring, water pipes, and gas lines. Water infiltration can lead to pipe corrosion, electrical failures, and even hazardous gas leaks, compromising both safety and service reliability.

  • Vehicle Tunnels – Water seeping through tunnel walls or accumulating on road surfaces creates hazardous driving conditions. Pooled water can reduce tire traction, increasing the risk of skidding, accidents, and severe traffic disruptions.

  • Subway Tunnels – Built beneath densely populated urban areas, subway tunnels are highly vulnerable to leaks from surrounding soil and aging infrastructure. Persistent water intrusion can disrupt train operations, cause service delays, and lead to costly maintenance and repairs.

  • Rail Tunnels – Water intrusion in rail tunnels poses significant risks, particularly to electrical components and track stability. Excess moisture can weaken the track bed, cause rail misalignment, and in extreme cases, contribute to derailments.

  • Pedestrian Tunnels – Water leaks in pedestrian tunnels create slippery surfaces, increasing the risk of slips and falls. Persistent dampness also encourages mold and bacteria growth, leading to poor air quality and potential health hazards.

Waterproofing and leak repair solutions are essential to maintaining tunnel safety, functionality, and longevity. Addressing water intrusion early can prevent costly damage and serious operational disruptions.

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 ingress poses both immediate and long-term challenges, driving up project costs and leading to structural deterioration if left unaddressed.

Leaks through cracks, joints, and voids can be effectively sealed using advanced injection systems that employ cost-efficient and highly reliable chemical grouts, such as multi-component acrylate gels and single-component polyurethane resins.

When properly engineered, resin injection systems do more than just stop leaks—they also stabilize surrounding soil by transforming loose sands into a firm, sandstone-like consistency and consolidating gravel into a bonded, load-bearing structure. This not only enhances the durability of the tunnel but also improves its overall resilience against future water intrusion.

Example: SealBoss Acrylates Used to Seal Leaks in Tunnel

What are Acrylate Gels?

Acrylate gels, also known as acrylic gels, are highly flexible, ultra-low viscosity, hydrophilic sealing agents designed for non-structural injections. With a consistency similar to water, they effectively penetrate cracks, joints, and voids, making them ideal for grid, curtain, and bladder injection applications, as well as use in injection tube sealing systems.

Thanks to their exceptionally low viscosity and surface tension, polyacrylate gels offer superior penetration capabilities, allowing them to reach even the smallest fissures. Their adjustable gel time enables precise application, adapting to varying job site conditions such as temperature and injection distance.

When in contact with water, acrylic gels expand hydrophilically, creating a compression seal that prevents further leakage. This swelling behavior makes them an effective solution for waterproofing applications. Additionally, acrylate injection equipment can be easily cleaned with water, simplifying maintenance.

SealBoss provides a comprehensive range of high-performance products designed to control water ingress in underground mining operations, tunnels, and other commercial structures facing leakage challenges. Our solutions support waterproofing, soil consolidation, crack and joint repair, sealing, bonding, and cavity filling, ensuring durable and long-lasting protection.

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

How to Seal Leaks | Repair Cracks in Shotcrete

How to Seal Leaks | Repair Cracks in Shotcrete

How to Seal Leaks and Repair Cracks in Shotcrete

Shotcrete is a versatile and durable material widely used in construction for creating complex structures, including decorative elements in zoos and theme parks.

However, like any other material, it is prone to developing cracks and leaks over time. Addressing these issues promptly is crucial to maintain the integrity and appearance of the structures. This article outlines a practical example of how the SealBoss Water Stop System was effectively used to repair a decorative shotcrete structure at the Omaha Zoo.

Shotcrete Water Intrusion: Why Risk Is Higher than CIP and How Injection Mitigates It

Shotcrete is a workhorse for tunnels, basements, shafts, tanks, and slope stabilization. But compared with well‑vibrated cast‑in‑place (CIP) concrete, shotcrete has a higher risk of water intrusion—not because the material itself is inferior, but because placement variables (nozzle technique, rebound, and bonding) can create porous zones, laminations, and honeycomb voids.

The good news: injection grouting precisely targets those leak paths without demolition.

Common Leak Sources in Shotcrete

  • Rebound pockets & laminations behind the finished face or around congested steel
  • Honeycombs/voids near corners, embeds, and penetrations
  • Cold/day joints with incomplete bonding between lifts
  • Interfaces at shotcrete‑to‑rock or shotcrete‑to‑existing concrete
  • Cracks (shrinkage, thermal, or flexural) that become water carriers

Summary – TL;DR

  • Shotcrete is more sensitive to workmanship than CIP. That sensitivity increases the odds of rebound pockets, laminations, and honeycombs that become water pathways.
  • The fastest, least disruptive fix: chemical injection—spot seal and stop active water with hydrophobic/hydrophilic polyurethane (PU) foam injection, or for large scale porosity in below grade structures seal with low viscosity PU foam or ultra‑low‑viscosity acrylate gel (curtain injection) as needed.
  • Use epoxy only if structural crack repairs are specified and after water control.
  • Use lowest possible, controlled injection pressure, tight port patterns, and clear pass/fail criteria.

How to Seal Leaks and Repair Cracks in Shotcrete – The Challenge

Leaks and Cracks in Decorative Shotcrete

The Omaha Zoo faced a significant challenge when a decorative shotcrete structure, an integral part of the zoo’s aesthetic appeal, began showing signs of deterioration.

Cracks and leaks had developed, primarily due to an irrigation system installed above the structure. Water seepage through these fissures threatened the durability and appearance of the faux rock face, necessitating an urgent and effective repair solution.

The Solution: SealBoss 1510 Foam and P2002 Polyurethane Pump

To address the leaks and repair the shotcrete structure, a technical representative from SealBoss was called upon. The solution proposed involved the use of the SealBoss Water Stop System, specifically the 1510 Water Stop / Leak Seal Foam and the compact P2002 Injection Pump, along with SealBoss Evolution AL Packers (1/2″, 5/8 BH/Zerk).

The objective was clear: Seal the leaks in the shotcrete and repair the cracks effectively without compromising the structure’s aesthetic value. The SealBoss system was chosen for its proven efficiency in such scenarios.

The Process: Hydro Active Foam Injection Technique

The shotcrete leak seal repair process began with a thorough assessment of the structure to identify all visible voids and cracks. The SealBoss team then employed the hydro active foam injection technique, using the P2002 drill injection machine along with 1/2 AL & 5/8 injection packers.

SealBoss 1510 was injected into the shotcrete cracks until visible penetration was observed on the face of these cracks. This process required multiple injections at various points to ensure that the foam traveled deep into the cracks, forming a dense, closed-cell compression seal upon expansion. One of the remarkable observations during the process was the expanding foam pushing out from the cracks, indicating its excellent travel and coverage within the network of fissures.

The Outcome: A Leak-Free, Restored Structure

Following the injection process, the structure underwent a rigorous inspection to ensure that all leaks were sealed. The SealBoss system proved its efficacy, as the structure passed the inspection with no signs of leakage. The aesthetic integrity of the structure was maintained, with minimal visible impact from the repair process.

Seal Leaks and Repair Cracks in Shotcrete – Frequently Asked Questions

Is shotcrete inherently leaky?

No. Properly placed shotcrete can be watertight. But its placement method increases the odds of defects (rebound pockets, laminations, honeycombs) that raise the risk of leakage versus CIP. Injection addresses those specific pathways.

Will PU alone fix my problem?

PU foam is ideal for stopping active water quickly. If the wall is generally permeable or seepage is diffuse, add an acrylate gel curtain to create a continuous barrier.

When should I consdider epoxy?

Only if specified and after water is controlled. Epoxy is for structural crack repair and requires dry conditions to bond properly.

What injection pressures should I use?

Start low and increase only as necessary. The goal is flow‑based infiltration along leak paths, not fracturing the concrete.

How will I know it worked?

No visible flow, a dry face after 24–72 hours, and no damp telegraphing beyond the grid.

In below grade structures damp spot or wet areas may show up later if water table rises or dried out soil becomes saturated. Water may migrate to areas that have not been treated.

SealBoss 1510 Leak Sealing Application

What is the Purpose of a Spillway in Dams?

A spillway serves a critical function in dam systems. Either incorporated into the dam’s structure or built adjacent to it, a spillway facilitates the controlled and secure discharge of surplus water downstream.

Introduction

Spillways play a critical role in safely managing excess water in dam systems. Over time, leaks can develop in cold joints and cracks, posing structural risks and operational challenges. Traditional repair methods often fall short—especially under high water pressure.

SealBoss 1510 Water Stop Foam offers a reliable solution. Its hydro-active, expanding polyurethane formula penetrates deep into leaking areas, sealing active water flow and forming a durable, watertight barrier. This article highlights a successful spillway leak repair using Water Stop Foam, demonstrating its effectiveness where other methods failed.

SB 1510 Polyurethane Foam in Dam and Spillway Leak Sealing

Dam Spillway Leak Sealed with Advanced Polyurethane Foam Injection

When it comes to critical infrastructure, few challenges are more pressing than water intrusion in dams. One of the most effective solutions available today is SealBoss 1510 Water Stop Foam, a high-performance, hydro-active polyurethane product. This case study and technical overview demonstrate how a dam spillway leak was sealed using SB 1510 polyurethane foam, offering a lasting and economical solution.

Why Polyurethane Foam for Dam and Spillway Leak Repairs?

Polyurethane foam is widely respected for its low viscosity and superior adhesive properties, making it ideal for sealing active water leaks in dam and spillway structures. Its hydro-reactive nature enables it to expand on contact with water, effectively filling cracks, joints, and voids — even under high-pressure flow.

When injected into a leaking dam or spillway, the foam penetrates deeply into fissures and gaps. It reacts quickly with water, expands, and cures into a solid, waterproof barrier. This process forms a robust seal that prevents further water ingress and strengthens the surrounding substrate.

How Dam Spillway Leaks Are Sealed Using SealBoss 1510

The leak remediation process begins with drilling holes along the affected cold joints or cracks in the dam spillway. Mechanical injection packers are then installed, allowing SealBoss 1510 to be injected precisely where needed. The foam expands rapidly within the concrete structure, bonding to the substrate and stopping the leak at its source.

After curing, the foam forms a permanent repair that is resilient, flexible, and capable of withstanding ongoing hydrostatic pressure—making it one of the best solutions when a dam spillway leak must be sealed quickly and reliably.

Case Study: Dam Spillway Leak Sealed After Multiple Failed Repairs

Background: Persistent Cold Joint Leak

SealBoss was contracted to repair a leaking cold joint in a dam spillway—one that had already failed four previous repair attempts. Prior caulking had eroded due to continuous water pressure, allowing active leakage through the “V” notched joint. With increasing water infiltration, the situation called for a proven, robust method to get the dam spillway leak sealed once and for all.

Step-by-Step: Leak Sealing with SB 1510 Water Stop Foam

  • Surface Prep and Joint Access
    Technicians began by removing loose and deteriorated caulking to fully expose the leaking joint. Drill holes were made adjacent to the joint, and active water flow confirmed correct placement.

  • Oakum Soakum Technique
    To immediately address the gushing leak, the team applied the Oakum Soakum method using SealBoss 1500 Seal Oakum saturated with SealBoss 1510 and accelerated with 15x Accelerator for fast reaction and curing. The oakum was placed directly into leaking crevices to form an initial water block.

  • Injection Packer Installation
    Next, 13-100 AL mechanical packers were installed in a staggered vertical pattern, based on SealBoss’s 1 – 2 – 3, 45 – Degree Injection Guidelines. Strategic spacing ensured coverage while avoiding rebar interference.

  • Polyurethane Injection
    Using the SealBoss P2002 injection pump, catalyzed SB 1510 foam was injected starting from the lowest packer. Controlled pauses allowed the resin to expand fully, minimizing waste while maximizing penetration.

Result: Dam Spillway Leak Sealed with Lasting Effect

All leaking joints were successfully sealed. The high-pressure, active leaks were stopped effectively, and the structure’s integrity was restored. This application proved once again that SealBoss 1510 polyurethane foam is a powerful tool in dam and spillway leak sealing.

Conclusion

If you’re facing persistent water intrusion, cracks, or joint failures in spillway structures, getting the dam spillway leak sealed properly is critical.

The SealBoss 1510 Water Stop Foam injection system provides a fast, durable, and cost-effective repair method—even under high-flow conditions.

This proven technology not only stops active leaks but also extends the life of dam infrastructure. As this case study demonstrates, polyurethane grout injection is the gold standard for dam and spillway maintenance.

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.
