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.

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.

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.

Long-term measures involve regular structural inspections and the development of comprehensive maintenance plans, encompassing routine cleaning of drains and re-application of waterproofing materials.

The integrity of below-grade parking garages is crucial for the safety of its users and the preservation of asset value. Stakeholders need to understand the impacts of water damage and adopt proactive strategies to mitigate risks. This approach helps extend the lifespan of parking structures, reduces maintenance costs, and ensures a safe, functional environment for users.

Maintenance of Drainage Systems

Effective drainage is paramount in preserving the structural integrity of parking garages. Poor drainage can lead to water ponding, increasing slip-and-fall risks, and accelerating concrete deterioration. Maintaining an efficient drainage system is thus essential for avoiding frequent and costly repairs.

Contractors tasked with improving drainage should focus on optimizing the existing system. This involves evaluating the system’s effectiveness, cleaning drains, removing debris, and recommending a schedule for regular inspections and ongoing maintenance.

While improving drainage systems may require an upfront investment, the long-term benefits, including reduced maintenance costs, structural preservation, minimized safety risks, and enhanced operational efficiency, are substantial.

Combating Corrosion

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.

NSF Drinking Water Certified Water Stop Foam - P2002 Pro-Kit

Rush Delivery and On the Job Training

This newer water treatment plant has the capacity to meet the needs of the growing city’s population and industrial demands. It utilizes state-of-the-art technology to reduce seasonal taste and odor issues, treats for sulfates from Devils Lake discharges, and meets regulatory requirements related to pharmaceuticals, pesticides and herbicides. Located in a harsh climate, the Treatment Plant is an all indoor facility with multiple basins for the various processes of treatment.

A SealBoss Technical made a rush delivery of a P2002 Pro-Kit and NSF Drinking Water Contact Certified SealBoss Water Stop Foam to the North Dakota Water Treatment Plant where previous attempts to mitigate various leaks through concrete cracks had failed. SealBoss provided intensive on the job crack injection training for the in-house maintenance and repair team to provide them with product and application knowledge to be able to inject and leak-seal any cracks within the facility successfully.

The chlorine basin had developed cracks and water with minimal solids had been leaking from the bottom of the basin on to the pumps and other mechanical components. Previously, the leaking cracks had been unsuccessfully addressed by a contractor with a undisclosed product and were found to be covered with an epoxy paste.

Prior to injection with SealBoss hydro active hydrophobic polyurethane foam the face of the concrete needed to be cleaned and stripped back to bare concrete. Some leaking areas had previously been injected by drilling directly into the crack (which is not a recommended procedure for this type of application) and were left unfinished with some ports or parts thereof still in place. The old remaining ports needed to be removed and the old drill holes were quickly and temporarily plugged with SealBoss 3/8” Hammer-in ports.

Once this was accomplished, new injection holes were drilled following the SealBoss 1, 2, 3, 45-Degree Injection Guidelines and starting roughly 6” from the center of the crack and placing packers in a staggered fashion. Under the job site conditions the SealBoss 45-Degree packer installation technique provided for much better product penetration and travel within the cracks and hairline fissures. Once all the holes were drilled the SealBoss Evolution 13-100AL aluminum packers were placed and the overhead injection began.

SealBoss NSF/ANSI 61 certified 1510 Water Stop Foam chemical grout is approved by the supervising engineering firm for the crack and leak-seal repair on this project. The product was injected with the SealBoss P2002 high pressure single component injection pump system.

Within a short time the low viscosity SealBoss 1510 Foam was traveling through the cracks and began reacting. Refusal of the resin from the face of the crack was visible at distances far exceeding the next packer hole indicating very good penetration.

Utilizing the SealBoss 1, 2, 3, 45-Degree Injection Method with staggered packer placement, rather than drilling directly into the cracks, the low viscosity SealBoss 1510 chemical grout was able to travel much farther inside the cracks, hairline fissures and non-visible shrinkage cracks thus creating an immediate and permanent seal.

SealBoss provided intensive on-the-job crack injection training for the in-house maintenance and repair team and taught them all the product and application knowledge to be able to inject and leak-seal any cracks within the facility successfully.

fter several hours of on-site guidance, the facility’s repair team felt confident in devising a strategy to address the remaining cracks. They were also well-acquainted with the systems for anticipated future leak repairs.

Crack Injection

Water Stop / Leak Sealing Crack Injection
and Structural Crack Injection

What is Crack Injection?

The process of Crack Injection involves injecting an adhesive chemical grout or resin to connect and seal a cracked foundation, slab or wall.

If left untreated, cracks in concrete structures will grow larger over time leading to more destruction and rebar corrosion.

Crack Injection, in infrastructure terms, is the application of a chemical grout, resin or bonding agent into a substrate to repair, seal, permeate and consolidate the substrate to extend the design life of a structure.

Crack Injection can be Grouped into Two Subcategories

The term crack injection, specifically concrete crack injection, covers a variety of injection techniques primarily used in infrastructure waterproofing repairs and structural concrete repairs.

Category 1
Water Stop and Leak Sealing Crack Injection

Injection methods designed to prevent water ingress and migration are subcategory of crack injection known as chemical grouting — referring to the gels, resins and foams as chemical grouts. Chemical grouts include polyurethane resins and acrylic resins. These products are designed to work well in a wet environments. Water stop foams react on contact with water and expand to stop high velocity water flow. Polyurethane resins form semi rigid or flexible seals to permanently prevent water migration.

Category 2
Structural Crack Injection

Methods and products designed to structurally repair concrete are combined in another subcategory of crack injection, known as epoxy crack injection. Epoxy resin adhesives, categorized by strength, viscosity and gel-times, provide outstanding structural properties — a prerequisite for use as a prime load-bearing cracked concrete repair solution.

Powerful Polymers – Comparing Two Categories of Crack Injection Chemical Grouts

Hydrophobic and hydrophilic polyurethane based chemical grouts and structural epoxy based resins are the two major product groups used for crack injection. To better understand the characteristics and differences, please refer to our product comparison called ‘The Crack Injection Superheroes’.

Basement Crack Injection Kit – The Ultimate Solution for Leak Sealing and Repair

Tracing the Root Cause

The culprits behind basement cracks often lie in the settlement of backfill or inadequate soil conditions. The resulting stress cracks can pave the way for unwelcome moisture intrusion, leading to further damages and the development of mold and unsightly damage over time.

A Comprehensive Crack Repair System

Enter the SealBoss Basement Crack Injection Kit, your ultimate weapon against leaks. This kit simplifies the repair process by delivering an effective, user-friendly solution to stop water in its tracks. The cured seal is airtight, watertight, and hydrophobic, deterring water incursion with utmost efficiency.

Our easy to use kit comprises a SealBoss P2002 high-pressure injection pump, SealBoss 1510 Water Stop Foam hydrophobic resin coupled with a 15x catalyst, and SealBoss Mechanical Injection Packers. When used in unison, these tools empower you to counteract hydrostatic pressure and fill the crack with a specialized water activated polyurethane foam that reacts with the existing moisture.

For complex structural repairs, consider employing the SealBoss Epoxy Injection System and Epoxy Repair Kits. For an in-depth comparison of the two systems, we invite you to explore our article on Epoxy versus Polyurethane.

Crack injections can conveniently be performed from within the structure (aka negative side repair), saving you both time and labor.

Leak Sealing Crack Repair Procedure

We put our Crack Injection Kit to work in a residential basement structure that had three prominent cracks showing signs of moisture intrusion. Signs of a previous unsuccessful repair attempt were also evident.

Post a thorough cleaning and strategic planning, we embarked on the repair process using our 1, 2, 3, 45 Degree Injection Guidelines, initiating with hole placement. The positive movement of water from drill hole to crack and inter-hole travel confirmed the readiness for the crack to be sealed.

The cracks, being approximately 3/8” wide, demanded a slowed injection to prevent wastage and overfill. As the catalyzed 1510 hydrophobic resin flowed from the crack, we employed a spray bottle to expedite the hydro-active reaction of the SealBoss 1510, allowing the foam to seal the crack surface as it cured.

One significant vertical crack had penetrated the foundation and was visible above ground. This crack was treated with foam from the floor up to 12” below the sill plate. The exterior was sealed to guide the expansion and avert exterior leakage. All cracks were sealed successfully, with surplus foam removed to prepare the structure for subsequent treatments, including aesthetic improvements.

Please note, we highly recommend consulting a specialist to investigate and correct any underlying and ongoing causes of structural damages, crack formation, and settling — including, but not limited to, backfill settlement and poor soil density.

Hairline Crack Injection

Super Fine Crack Injection

What are Hairline Cracks and how do they develop?

Fine cracks in concrete, thinner than a credit card thickness, are considered hairline cracks. here are a number of reasons concrete structures could form hairline cracks.

Common causes of hairline cracks in concrete structures and foundations

Shrinkage
Concrete shrinks in volume as it dries. During this process of contraction, hairline cracks may develop.

Thermal Movement
Concrete expands and contracts during temperature changes. This process can cause hairline cracks to form in the structure.

Settlement
Foundation settlement can cause stress in a structure and lead to cracking. Voids varying in size from hairline cracks to more severe fractures and fissures can be observed.

Hairline Crack Injection Job Walk Comments

– In the image presented, we highlight a detail we have previously discussed with the injection team during technical training. The almost imperceptible hairline crack beautifully demonstrates the resin’s travel, moving from the drilled hole pointy of injection within the crack and emerging on the wall’s surface.

For effectively treating ultra-thin hairline cracks, it is advisable to utilize a low-viscosity chemical injection grout. This ensures optimal material penetration within the structure. Additionally, injection packers are typically positioned in close proximity to one another and nearer to the crack. This arrangement is due to the anticipated higher injection pressures and the increased challenges associated with material dispersion.
