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

Using SealBoss Seal Oakum for pipe penetration waterproofing by following the “Oakum Soakum” technique with SealBoss Water Stop Foam 1510 / 1570 and Oakum.

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

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.

For the Comprehensive SealBoss Crack Injection Guideline click here.

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.

Read more on the Curtain Injection Technique – click here.

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

Soak SealBoss Oakum in SealBoss Polyurethane Grout and water
Pack the soaked Oakum around the pipe
Use a SealBoss Injection Needle to fill any remaining gaps with chemical grout

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.

Parking Garage Waterproofing

Injection Technology for Parking Garage Infrastructure Maintenance

Introduction:

Below-grade parking garages and above-grade garages are vital components in urban infrastructures, particularly in densely populated areas where surface parking is scarce. These garages provide a crucial solution for parking needs but are inherently prone to water leaks, leading to serious structural integrity issues.

Commercial parking garages, whether situated above or below ground, face a significant risk of water damage. The primary construction material, concrete, is naturally prone to developing shrinkage and stress cracks over time. Additionally, concrete’s porous nature, combined with the existence of construction and cold joints, creates potential pathways for water to penetrate. This infiltration of water can trigger various issues, notably the weakening of the concrete structure and the corrosion of embedded steel reinforcement bars (rebar).

Such deterioration not only compromises the structural integrity of the garage but also leads to escalated maintenance needs and potential safety hazards.

The consequences of such leaks and deterioration extend beyond mere inconvenience, posing safety risks, incurring costly repairs, and diminishing property values.

This article outlines common challenges of waterproofing these above-grade and subterranean structures, outlining the detrimental effects of water on concrete, strategies for early detection of structural compromises, and both immediate and long-term actions for maintaining the structural integrity and safety of these essential facilities.

Polymer Grout Injection Water Stop: The Final Line of Defense

Polyurethane grout injection plays a crucial role in parking garage waterproofing, especially in areas prone to leaks. This material provides a robust solution for sealing and protecting against water infiltration. When integrated into maintenance plans, it acts as a formidable barrier against moisture-related damages.

Polymer polyurethane and acrylate grouting include multiple repair techniques such as:

Crack Injection
Joint Injection
Conduit & Pipe Penetration Sealing
Curtain Wall Grouting
Soil permeation, compaction, consolidation, and stabilization grouting

Polymer Grout for Parking Structure Waterproofing

The Detrimental Effects of Water on Concrete Structures

Water migration in concrete parking garages can lead to corrosion, compromising the structural strength of the concrete, increasing the likelihood of further cracking, spalling, and in severe cases, complete structural failure. These issues not only present significant safety hazards but also accelerate the need for increasingly extensive repairs.

Recognizing the Signs of Structural Compromise

Early detection of water-related damage is critical for the longevity of parking structures. Key indicators include cracking, spalling, efflorescence (a greyish white, powdery substance indicating water movement within concrete), and rust stains on concrete surfaces. These signs point to potential rebar corrosion and overall weakening of the concrete structure.

Immediate and Long-Term Waterproofing Actions

Effective waterproofing requires both immediate interventions and long-term strategies.

Immediate actions often include sealing leaks with polyurethane polymer grout or acrylate grout injection and allowing for additional drainage to prevent water accumulation.

Water migration of any source, including groundwater, rain water and sprinkler runoff, and environmental factors like minerals and vehicle emissions can significantly corrode concrete and metal components. Polymer grout injection, when correctly applied, effectively seals against these elements, prolonging the garage’s structural integrity.

Cost Considerations and Long-Term Value

Investing in polymer grout application, including hydro-active foam, polymer gels and resins, is cost-effective in the long run, offering benefits such as reduced repair costs, extended lifespan of the garage, enhanced safety, and increased property value.

Complementing Polymer Grout Technology with Other Preventative Measures

A comprehensive corrosion prevention strategy can include additional measures like proper ventilation, regular cleaning, and the application of specialized coatings and sealants, alongside polyurethane grout injection methods.

Regular inspections and proactive maintenance are key to sustained effectiveness in corrosion prevention. Any signs of new corrosion should be promptly addressed to maintain the structure’s integrity.

The Importance of a Comprehensive Corrosion Prevention Strategy

A holistic approach to combating environmental corrosion is essential for the long-term success of waterproofing efforts. This strategy should encompass quality application of polyurethane grout and integration into a broader corrosion prevention plan.

Sealing of Gaps and Spaces Around Electrical Conduits and Pipes

Moisture poses significant risks to electrical systems within parking garages, potentially leading to hazards such as short circuits and electrical fires. Ensuring electrical safety requires a multifaceted approach that can combine polyurethane grout application with other comprehensive safety measures. This strategy is vital for reducing the risks associated with water infiltration.

Polyurethane grout is instrumental in mitigating these risks by effectively sealing areas around electrical installations and sealing of leaking conduits and the sealing of other openings in the structure such as annular spaces and gaps around drainage pipes.

The initial investment in polyurethane grout application for electrical safety and the sealing of conduit and pipe penetrations pays off in the form of reduced maintenance costs, enhanced safety, and operational continuity. Electrical, conduit, and pipe penetration safety in parking garages should include regular inspections and maintenance.

Conclusion

Waterproofing below-grade parking garages is a critical aspect of urban infrastructure maintenance. By understanding the challenges, recognizing the signs of damage, and implementing both immediate and long-term waterproofing strategies, owners and stakeholders can protect their investments, ensure public safety, and maintain the structural integrity of these essential facilities.

Soil Stabilization in Cold Weather

Best Practices and Tips

Solid Ground, Even When It’s Cold Around: Expert Tips for Soil Stabilization in Cold Weather

As the cold season approaches and temperatures begin to plummet, the challenges of soil stabilization in cold weather become more pronounced.

However, with the right precautions and techniques, it is entirely possible to achieve effective soil stabilization even in low temperature conditions. In this article, we provide some essential tips and best practices for soil stabilization with SealBoss 1570 / 1570 during the colder months.

Avoid Working in Frozen Ground
The primary consideration when thinking about soil stabilization in cold weather is the state of the ground. If the water table is frozen, it is a clear indicator that the soil is too. Frozen soil lacks the permeability required for the effective penetration of polymer resin into the soil soil. Attempting stabilization on such ground would not only be ineffective but also a waste of valuable materials. In such scenarios, it is advisable to wait for more favorable conditions.

Condition Your Equipment and Materials for Soil Stabilization in Cold Weather
Cold weather can significantly affect the performance of your SealBoss soil stabilization materials and equipment. To ensure optimal results:

Store in a Heated Environment: Materials and equipment should be stored in a heated environment overnight. For instance, SealBoss Polyurethane Grout should always be maintained above 60 degrees. Cold materials tend to react slower and increase in viscosity.
Drums and Smaller Pails: Drum band heaters and heated drum mats are excellent tools to ensure your product remains at the optimal temperature during winter soil stabilization applications. However, always exercise caution to avoid overheating the polymers. For applicators working with smaller pails, it is advisable to keep both materials and equipment in a heated, insulated space until they are needed. Portable heaters can help sustain a warm atmosphere, ensuring the materials remain at optimal temperatures. Additionally, consider using electric pail heaters, which are specifically designed to keep resins at their ideal temperature for application.
Speeding Up Reaction Time: In situations where the material reacts too slowly, incorporating a higher percentage of SealBoss 15X Accelerator can effectively accelerate the reaction time.
Heated and Unheated Pumping Equipment: For those utilizing advanced heated equipment, it is common for the machinery to maintain a temperature that’s approximately 35-45 degrees above the ambient external temperature. Many of the more robust foam pumps come standard with built-in electric heaters. If your pump lacks this heating feature, investing in an electric radiator heater can be a wise choice.

Conclusion
Cold weather doesn’t have to halt your soil stabilization efforts. By ensuring the ground is not frozen and properly conditioning your materials and equipment, you can achieve successful soil stabilization even in cold conditions.

Dam Spillway Leak Sealed

SealBoss 1510 Polyurethane Foam

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.

SB 1510 Polyurethane Foam in Dam and Spillway Leak Sealing: An Overview

Polyurethane foam, known for its superior adhesive properties and low viscosity, plays a pivotal role in sealing leaks in dams and spillways.

Its unique characteristics, superior adhesive properties and low viscosity, make polyurethane foam an optimal choice for addressing expansive cracks, joints, and gaps in concrete structures. Hydro-active foam penetrates deeply into these openings and crevices, efficiently arresting active and high-velocity water flow, while also filling the cavities to form a waterproof seal that impedes future water seepage.

The remediation process initiates by drilling holes around the leak-prone area within the concrete perimeter. Following this, specialized injection equipment introduces polyurethane foam through the installed injection packers in the drilled holes. Upon injection, the foam expands and fills the concrete voids, establishing a sturdy bond with the surrounding substrate. After curing, the foam evolves into a solid and durable repair, effectively sealing the water leak in the spillway. Polyurethane water stop foam injection offers an effective and economical solution for many dam spillway leak repairs.

Sealing Dam Spillway Leaks with 1510 Water Stop Foam: A Case Study

How to Seal a Dam Spillway Leaks with Hydro-Active Polymer Injection

SealBoss was enlisted to tackle the problem of leaking Cold Joints, a situation that had resisted repair through four prior methods. The caulking previously deployed to seal the joint had been compromised, leading to water erosion and diminished adhesion between the caulking and the concrete. As a result, water was infiltrating through the “V” notched joint at an increasingly concerning rate.

Preparation and Injection Procedure

The repair endeavors focused on sections with active water leaks – characterized by high velocity and volume – visible efflorescence, and loose caulking. Caulking removal was required to expose the cold joint.

In preparation for placing the mechanical packers, the contractor drilled holes. When water began flowing from these holes, it was clear the drill bit had successfully intercepted the joint.

At times, it may be beneficial to keep a drill hole unsealed initially, delaying the installation of the injection packer. This approach can serve as a pressure relief point, helping to alleviate hydrostatic pressure and regulate water flow.

In preparation for the injection procedure and to curb water flow, the Oakum Soakum Technique was employed to address the gushing leaks first. SealBoss 1500 Seal Oakum, soaked in SealBoss 1510 Water Stop Foam catalyzed with a significant amount of SealBoss 15x Accelerator for quick setting and curing, was inserted into the actively leaking crevices and held in place until cured.

After completing the oakum patching process, the next phase involved installing the injection packers. The 13-100 AL packers were set in place following the 1, 2, 3, 45 Degree Injection Guidelines, with a 14″ staggered vertical spacing and about 7″ on either side of the joint to avoid interfering with the rebar.

The injection procedure commenced from the lowest packer, using SealBoss P2002 pumping equipment to inject the catalyzed SealBoss 1510 Water Stop Foam. We suggest occasional injection pauses to let the resin expand and to reduce product wastage.

Success – Dam Spillway Leak Sealed

Through these measures, all the joints were successfully sealed, and active leaks were effectively addressed.

Conclusion

In summary, the usage of polyurethane foam, particularly SealBoss 1510 Water Stop Foam, has proven to be an effective and economical solution for dam and spillway leak sealing.

The method’s success lies in the foam’s ability to penetrate deep into the crevices and gaps, providing a robust, waterproof seal.

The above case study underscores how a strategic, methodical approach can result in successful sealing of active leaks, reaffirming the significance of this solution in the field of dam and spillway maintenance and repair. As we look forward, we can anticipate that such techniques will continue to evolve, further enhancing the efficiency and effectiveness of leak repair in dam spillways.

Dam Erosion and Sedimentation Control with Polyurethane Grout Injection Systems

Introduction:

Erosion and sediment accumulation in dams can present great challenges, threatening the structural integrity and functionality of these important infrastructures. In the face of such risks, polyurethane grout emerges as a game-changer, offering a durable and versatile solution to tackle these problems. This article underscores the advantages of polyurethane grout for dam repair, highlighting its role in ensuring long-term safety and efficiency.

Polyurethane Grout for Erosion, Sediment, and Leak Control

Erosion: A Silent Threat to Dams

Erosion in concrete dams, as well as in earth dams, is more than a maintenance issue; it is a significant risk to their stability and safety. Water seeping through cracks, joints, and fissures gradually erodes concrete and soil, potentially leading to severe damage or failure. Addressing erosion is crucial for maintaining the dam’s structural integrity and ensuring its long-term viability.

Polyurethane Grout: An Answer to Dam Erosion Challenges

Polyurethane grout stands out as an effective solution to combat erosion. Its flexibility, as opposed to the rigidity of cementitious grouts for example, allows it to adapt to the dam’s natural movements without losing its sealing capabilities. Its quick curing time, hydro-active nature and water stop capabilities are a boon for minimizing operational downtime, especially in essential hydroelectric power generation or water supply dams. Versatile in use, including water stop crack injection, as well as soil stabilization, permeation and consolidation applications, polyurethane grout can be utilized in various dam types and scenarios, addressing a wide range of leakage, sedimentation, and erosion-related issues.

Economic Benefits of Polyurethane Grout

Using polyurethane grout is not only versatile and structurally sound but also economically advantageous. Its durability translates to fewer long-term repairs and reduced maintenance costs. For hydroelectric dams, the quick cure time of polyurethane grout minimizes energy production downtime, making it a cost-effective solution.

Sediment Accumulation: An Underestimated Issue

Sediment build-up in dams, often unnoticed until it becomes problematic, can reduce storage capacity and increase structural pressure. This build-up can also impede water flow, interfere with spillways, clog turbines, and affect water quality, which is especially important in drinking water sources.

Polyurethane Grout in Sediment Control

Polyurethane grout is invaluable in managing sediment challenges, in earthen and concrete dams. It can be used to create impermeable barriers, seal cracks, crevices, and joints, and solidify and stabilized substrate, effectively stopping sediment inflow.

Energy Efficiency in Dam Management

In dam management, optimizing energy production is crucial. Structural weaknesses and leaks can negatively effect a dam’s energy generation. Using polyurethane grout to seal these leaks supports maximum energy output and prolongs the infrastructure’s integrity and lifespan.

Environmental Safeguards and Polyurethane Grout

The environmental implications of dam leaks can be significant. Leaks may carry contaminants into natural waterways, harming aquatic life and ecosystems. NSF-Certified Polyurethane Grouts offer an environmentally safe solution for leak sealing, contributing to environmental sustainability.

Dam owners and operators can take several steps to address erosion and sedimentation effectively, including but not limited to:

Comprehensive Inspection: Conduct thorough inspections to identify areas affected by erosion.
Expert Consultation: Seek advice from engineers and contractors specializing in dam maintenance.
Quality Material Selection: Opt for high-quality polyurethane grout from reputable manufacturer.
Professional Contractor Hiring: Choose experienced contractors with a proven track record in using polyurethane grout.
Regular Monitoring: Implement regular monitoring and inspections post-repair to ensure ongoing effectiveness.
