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

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.

Protecting Investment and Public Safety

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.

Polyurethane Water Tank Sealants for Water Treatment Plants

Polyurethane injection chemical grouts serve as versatile and adaptable sealants, capable of effectively sealing cracks even in less than ideal conditions. These grouts can be employed to seal both narrow and wide cracks, as well as dry and actively leaking ones, and those containing contaminants such as mud or mineral deposits.

SealBoss low-viscosity, hydro-active, expanding polyurethane injection resins and chemical grouts provide exceptional penetration and adhesion properties when applied to wet or dry cracks, ensuring a robust and lasting seal.

In large concrete structures, cracks can emerge anytime after the pore and cure process, particularly in structures with extensive surface areas. As such, it is not unusual for cracks to require sealing during the construction phase. Furthermore, water leaks often manifest within the first five years of a structure’s life.

Water Treatment Plants are designed with strict specifications that necessitate minimal water migration, leakage, inflow, and infiltration. Failure to address water tank leakage properly and promptly can result in an increased risk of subsequent damage, including reinforcement and concrete corrosion.

For over three decades, Water Treatment Plants have effectively utilized SealBoss polyurethane water tank sealants to address and resolve water leak issues in their concrete structures, ensuring the integrity and longevity of these vital facilities.

Injecting Cracks Exhibiting Water Intrusion Prior to Seal Test

Jobsite Overview

A newly constructed tank at a Water Treatment Plant in the mid-west necessitated the sealing of its cracks using a specialized polyurethane water tank sealant system.

A SealBoss technical expert was called upon to provide on-site guidance for the injection procedure and to assist SealBoss Certified Installers in formulating a plan for a cold weather injection.

Inspection Process

After going over safety procedures, and following safety protocol, a three-person crew entered the tank to examine the leaks. They identified two overhead cracks with active, slow-moving leaks, manifesting as drips.

Water Tank Sealant System Implementation

The objective of this injection process was to inject NSF/ANSI 61 certified SealBoss 1510 Water Stop Foam into the leaking cracks within a non-permit confined space. The SealBoss Injection System, featuring Evolution 13-100 AL injection packers and the P2002 ultra-portable injection pump, was utilized for this purpose.

During the injection packers’ installation, some drill holes began to leak, indicating successful intersection with the crack for packer placement. Once the injection ports were secured, warm water was injected through each packer to facilitate catalyzation and accelerate the reaction. Next, the 1510 Water Stop Foam and 15x Accelerator were mixed in the P2002’s hopper, and the injection of the 1510 sealant into the water tank began.

Shortly after initiating the injection, the resin started displacing the water within the structure’s voids, causing water and gas to escape from the crack’s face. Injection continued until resin was observed emerging from the crack.

Each port was injected in a similar manner, adhering to the 1, 2, 3, 45 Degree Injection Guidelines. After the crack was completely injected and cured foam visibly flowed from the crack’s face, each packer was re-injected.

If immediate pressure buildup occurs, it indicates that the crack has been effectively sealed. If pressure does not build up instantly, the crack requires low-pressure reinjection to enable the resin to further penetrate the crack and displace any remaining water, ensuring a comprehensive and efficient seal.

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.

Water Ingress in Corrugated Tunnel Sealed

The University of Leicester enlisted the services of a U.K.-based specialty repair contractor to evaluate and rectify a steel corrugated tunnel/pipe approximately 1.8 meters in diameter.

The tunnel was exhibiting signs of persistent and significant water intrusion due to damage caused by corrosion, which led to the formation of cracks and perforations at the base of the duct.

The contractor devised and implemented a solution that could be applied from the confined interior space of the tunnel. The aim was to extend the lifespan of the structure by an estimated 25 years.

Given the substantial degree of water ingress from the elevated water table, a solution was needed that would not only stop the current water flow but also provide a robust barrier against future water infiltration and leakage.

The contractor identified a proven hydrophobic, hydro-active polyurethane water stop foam resin as the most suitable solution to tackle the fractures showing severe pressing water conditions.

Sealboss 1510 Water Stop Foam, NSF certified and activated by the 15x Accelerator, was the selected chemical grout to mitigate the severe and pressing water conditions.

The advantage of using this specific waterproofing injection grout in sealing the corrugated tunnel stems from its ability to seal not only wide, gushing water leaks but also the smallest of pores and capillaries in building elements that might otherwise allow water to seep to the surface.

The low viscosity of SealBoss 1510 chemical foam grout, coupled with the specially formulated SealBoss 15X Accelerator – which can be mixed at ratios ranging from 2% to over 20% by volume with the resin – enables a range of reaction profiles. These range from slow absorption into the concrete building components, sealing all capillaries and pores, to rapid water stop high-foamer expansion for sealing larger gaps and voids.

Carefully regulated addition of the accelerator allows for controlled expansion from nearly no expansion to forty times expansion. Due to its controlled expansion, the resin will either cure to form a tough semi-flexible seal or a compression seal gasket when expanding at pressure.

Following the injection as per specification, the corrugated tunnel repair now provides a watertight seal to the concrete, effectively preventing further deterioration of the building components due to water infiltration and seasonal frost.

Polymer Grout Systems to Prevent Coating Failure

Understanding the Critical Role of Coatings

Coatings extend beyond mere aesthetic enhancements; they act as essential protective barriers against a range of environmental threats. These include moisture, chemicals, UV radiation, and mechanical wear, all of which can precipitate coating failure. Effective coatings prevent corrosion, enhance durability, and ensure the underlying materials—concrete, metal, or wood—remain unaffected by adverse external conditions.

Techniques for Preventing Coating Failure

Polymer Grout Injection: A Remedy for Water Intrusion

Water intrusion stands as a principal factor in coating failure, leading to issues like blistering, peeling, and the eventual breakdown of the structural foundation.

Polyurethane grout injection method offers a formidable solution by filling and sealing cracks and voids that allow water entry. The expansive nature of SealBoss polyurethane foam creates a waterproof barrier, thus preserving the coating’s integrity and enhancing the structural stability of the construction.

Crack Injection: Restoration and Protection

Addressing cracks in construction materials is critical for preventing coating failure. SealBoss polymer crack injection fills these defects with a resilient resin that bonds with the material, reinstating its waterproofing properties and integrity. This approach not only repairs existing damage but also forestalls future degradation by establishing a robust barrier against external threats. Crack injection of water bearing cracks and active leaks is most commonly performed with hydro active PUR injection foams or hydrophilic polyurethane injection gel. Epoxy crack injection is the preferred method to reinstate structural strength.

Polymer Grout Curtain Injection: Comprehensive Shielding

Polymer Grout Curtain Injection offers a robust waterproofing solution that encases structures in a protective “curtain,” safeguarding them against water intrusion. This advanced technique is especially crucial for subterranean structures where persistent water pressure can compromise the integrity of coatings and the structural foundation itself. By creating a waterproof barrier, this method delivers a vital defense against moisture-induced coating failures, ensuring the preservation of both aesthetic and structural qualities.

The effectiveness of curtain grouting in reinforcing and extending the life of buildings and infrastructure is well-documented. For a tailored application, SealBoss deploys a range of materials including polyurethane injection foams and gels, alongside super low viscosity acrylate/acrylic gels. These materials are selected based on the specific requirements of the structure, ensuring optimal compatibility and effectiveness. The versatility of these polymers allows for their application in a variety of environments, adapting to different pressures and water exposure levels to provide a customized waterproofing solution.

The Importance of Early Detection and Comprehensive Solutions

Early detection and repair of coating failures are critical for maintaining structural integrity. Regular inspections and maintenance help identify potential issues before they escalate, allowing for timely interventions. Understanding the dynamics of water intrusion, osmotic blistering, microbe induced corrosion, and the implications of inadequate surface preparation and application mistakes are helpful for effectively preventing coating failure.

Conclusion

Preventing coating failure requires a multifaceted approach. The integration of SealBoss polymer foam, gels, and resins into maintenance and repairs offers durable and effective solutions to water intrusion and structural cracks, ensuring that coatings continue to fulfill their protective roles efficiently.

Addressing Dam Leakage

Several factors can play a role in the development of cracks in concrete dams. The natural shrinking of concrete, geological stresses, and inadequate soil compaction during construction all play their part. The persistent positive water pressure means that even the smallest of these cracks and fissures can become avenues for water leaks. As water continues to seep through, the cracks inevitably widen over time, potentially leading to significant water loss and a progressive deterioration of the dam structure.

Earthen dams also face the risk of significant water loss through leakage. The potential culprits are often inadequate compaction of fill dirt, faulty seams, and leaks forming underneath the dam’s breastwork. Seepage can undermine the stability of earthen dams, leading to safety concerns and operational inefficiencies.

As with most structural defects, water leaks will continue to increase until corrective action is taken.

Dam Repair – Sealing Active Leaks

Innovative injection solutions like SealBoss Water Stop Foams and Polyurethane Injection Resins have been utilized for dam repair for over three decades. Successfully used to seal leaks in both concrete and earthen dams, these materials have proven invaluable in enhancing the resilience of dams, preventing water loss, and extending the lifespan of these significant structures.

Sealing Active Leaks – Efficient Dam Repair with Water Stop Foam Injection

SealBoss 1510 Dam Leak Sealing Injection Grout has proven its efficacy at the Blue Heron Paper Mill Dam in Oregon City, Oregon. The procedure involved the use of the SealBoss SLP1C pump and Mechanical Injection Packers to deliver the grout effectively.

Addressing the considerable water infiltration from the Willamette River, the Water Stop Foam was accelerated using the highest recommended dosage of SealBoss 15X Accelerator. This resulted in the fastest setting Water Stop/High Foamer Injection System, tailored to deal swiftly and effectively with the leakage.

The procedure was meticulously executed, with injections performed at strategically chosen entry points. This approach allowed the injection team to cut off the water flow at the primary leak sources, as well as at other sites where seepage was less severe.

Prior to the initiation of the injection process, a technical sales representative from SealBoss, alongside the West Coast SealBoss sales manager, visited the site. Their visit served to clarify injection techniques, address any queries, and ensure the operation proceeded with complete understanding and efficiency.

The operation was successful, with all dam leaks effectively sealed – a testament to the proficiency and coordinated efforts of everyone involved in the operation.
