Case Study - Parking Structure Ceiling Leak Repair

Posted by Landon Feese on Oct 8, 2025 10:00:00 AM

Banner - Parking Structure Ceiling Leak Repair

Body - Parking Structure Ceiling Leak RepairA multi-level parking facility in downtown Los Angeles was experiencing significant water infiltration through its concrete ceiling. Building management had noticed increasing water staining and active leakage, particularly following rain events. The water migration around electrical conduits and light fixtures was most concerning, creating potential safety hazards with the electrical systems. Previous attempts to seal the ceiling using conventional surface treatments had failed to resolve the issue. With the structure serving high-end retail clients, the property management company required a solution to effectively stop the leaks while minimizing disruption to the facility's daily operations.

Initial Assessment

Inspection revealed that water was infiltrating through microscopic pathways in the concrete, with particularly noticeable intrusion around embedded conduits and penetrations. Engineers determined that concrete shrinkage had created tiny void spaces around these penetrations, some measuring only thousandths of an inch. Water was following these pathways, traveling along the outside of conduits and emerging at light fixtures and junction boxes installed in the ceiling. The ceiling showed distinctive water staining patterns radiating from these fixtures, confirming the migration pathway. Traditional polyurethane grouts would be too viscous to effectively penetrate these extremely small void spaces, requiring a material with exceptional flow characteristics.

Proposed Solution

Alchatek recommended using a specialized acrylic resin, Spetec AG 200. This material was selected specifically because of its extraordinarily low viscosity, significantly thinner than polyurethane alternatives, allowing it to travel through microfractures and voids that water could penetrate. Unlike thicker injection materials, acrylic resin can follow the same migration pathways as water, creating a waterproof barrier precisely where needed. The material's ability to travel long distances from injection points would minimize the number of injection ports required, reducing ceiling penetrations while ensuring complete sealing coverage around electrical conduits and other vulnerable areas.

Procedures

  1. Technicians identified and mapped all water intrusion points in the ceiling, identifying migration patterns to determine optimal injection locations.
  2. Strategic drilling and port installation were performed at intervals designed to intercept the water pathways, with particular focus on areas around electrical conduits.
  3. Ports were installed in a pattern that would allow the low-viscosity material to flow along the same paths as the water infiltration.
  4. Acrylic resin was injected through the ports, with continuous monitoring for material appearance at distant locations.
  5. Injection continued at each port until the material was observed emerging from adjacent ports or known leak points, confirming pathway filling.
  6. Engineers carefully monitored electrical systems throughout the process to ensure no disruption to the building's operations.

Results

The injection program successfully sealed the water infiltration pathways throughout the parking structure ceiling. Post-treatment monitoring through several significant rain events confirmed that all previously active leaks had been eliminated, with no further water migration observed around electrical fixtures. Most importantly, the acrylic resin's exceptional flow characteristics allowed for complete sealing with minimal disruption to the facility's operation. The property management company avoided spending an estimated $80,000-$100,000 that more invasive remediation methods would have required, while eliminating potential liability from water contact with electrical systems. The parking facility remained operational throughout the repair process, avoiding revenue loss that would have resulted from traditional ceiling replacement or excavation of the deck above.

Banner - Sealing Parking Structure Elevator Pit Leaks

Body - Sealing Parking Structure Elevator Pit LeaksThe property manager for a multi-level parking garage contacted Pavecon regarding persistent water infiltration in an elevator pit. The facility engaged Allana Buick & Bers, Inc. to develop a remediation strategy. Water leakage in elevator pits poses risks to equipment, safety, and can lead to service disruptions.

Initial Assessment

Inspection revealed multiple water entry points in the concrete walls of the elevator pit. The recurring water infiltration threatened the elevator system's integrity and created potential safety issues. Traditional repair methods would require extensive excavation and significantly disrupt parking facility operations, making them impractical and costly. The assessment determined that an effective solution was needed to address active leaks and provide long-term waterproofing without frequent maintenance.

Proposed Solution

The team selected a specialized polyurethane injection system (Spetec PUR F400) for the elevator pit leakage. This product effectively seals active water leaks in concrete structures by creating a waterproof barrier without extensive excavation. The method required only brief elevator shutdown periods rather than extended facility closures and could be applied even with active water infiltration.

Procedures

  1. Thoroughly cleaned repair areas to remove dirt, debris, and loose concrete that could compromise adhesion.
  2. Drilled through the concrete wall at strategic locations to access water infiltration pathways.
  3. Installed injection ports (zerk fittings) into each drilled hole to facilitate polymer application.
  4. Injected water when necessary to properly activate the polyurethane foam reaction.
  5. Polyurethane injection material was applied through installed ports, allowing it to expand and fill voids.
  6. Performed sequential injection following a pattern to ensure complete coverage of affected areas.
  7. Removed injection ports and patched drill holes with hydraulic cement after the injection process.
  8. Performed final inspection to verify cessation of all leaks.

Results

The polyurethane injection process successfully sealed all water infiltration points in the elevator pit, creating a waterproof barrier. The repair was completed within the scheduled timeframe, minimizing elevator system downtime. The project addressed approximately 17 linear feet of repair work.

After several substantial rain events, the elevator pit remained completely dry, confirming the solution's effectiveness. The property manager expressed satisfaction with the results, subsequently requesting additional services at other facilities and providing positive recommendations.

This solution demonstrated significant cost advantages over traditional methods, saving an estimated 60-70% compared to conventional waterproofing approaches while preventing potential damage to electrical and mechanical components.

Concrete Leak Repair for Below-Grade Spaces

Posted by Kreg Thornley on Jun 11, 2024 10:00:00 AM

Banner - Concrete Leak Repair for Below-Grade Spaces

Body - Concrete Leak Repair for Below-Grade SpacesConcrete leak repair is crucial for homeowners with leaks in basements or other below-grade spaces. Concrete can deteriorate over time due to imperfect construction, weather, wear, and unstable soil. However, effective solutions are available. This article explains how polyurethane leak seal grouts offer a cost-effective, durable fix for waterproofing your home.

The Problem with Standard Concrete Leak Repair Methods

Many homeowners initially try using sump pumps or hydraulic cement to remedy leaks. While these may provide a band-aid, they don't get to the root of the problem. Sump pumps only remove leaking water after it has already infiltrated. Hydraulic cement may temporarily stop the leak, but it is a rigid negative side bandied and thus prone to cracking as a structure shifts and settles.

The Benefits of Polyurethane Concrete Leak Repair

In contrast, experienced leak seal specialists rely on polyurethane grouts to stop leaks at their source. They inject this material into leaking cracks and joints. The grouts then react with water to form a flexible, watertight seal. Even as a structure naturally moves, the seal stays intact. Furthermore, polyurethane grouts provide industrial-grade strength while remaining safe for residential use.

The Importance of Professional Application

While injecting polyurethane grouts may sound simple, skilled professionals should handle it. Contractors undergo training to properly drill injection holes, prepare the components, and apply the product for maximum effectiveness. An expert will ensure the grout fully penetrates the leaks and forms a reliable, long-term seal.

Environmentally-Friendly Leak Repair

When selecting a contractor, look for one that uses NSF/ANSI/CAN 61 certified products. For example, most of Alchatek's leak seal grouts are NSF-certified to meet strict environmental standards. NSF certification involves both initial and ongoing testing, so you can trust these products always to be eco-friendly.

Key Takeaways

Concrete leak repair doesn't have to be a daunting task. Armed with the right products and expertise, a skilled contractor can provide an effective, long-lasting solution. When you choose a professional specializing in polyurethane leak seal grouts, you'll gain an ally in protecting your home against water intrusion.

Positive Side Waterproofing - What Property Owners Should Know

Posted by Kreg Thornley on May 28, 2024 10:00:00 AM

Banner - Positive Side Waterproofing

Body - Positive Side WaterproofingConstruction and building maintenance rely on effective waterproofing to ensure longevity and structural integrity. In fact, waterproofing protects against water damage and moisture-related structural issues in residential homes, commercial buildings, and infrastructure projects. Positive side waterproofing and negative side waterproofing are two different methods that are used based on factors like construction design, budget, and water exposure.

Positive Side Waterproofing

Positive side waterproofing applies the material to the exterior or positive side of the building structure—the side exposed to the elements and potential water ingress. As a result, this method creates an outer surface barrier that prevents water penetration. Positive side waterproofing offers several advantages. Firstly, it provides effective protection by preventing water intrusion from entering the structure, as the externally applied material acts as a barrier. Secondly, water pressure actually assists in the process by pushing the cured material against the building, which helps to maintain a watertight seal. Finally, since the waterproofing layer is applied externally, it allows for various aesthetic finishes to be applied on the interior surface without compromising the functionality of the waterproofing system.

Negative Side Waterproofing

On the other hand, negative side waterproofing treats the interior surfaces of the building. Consequently, this method prevents water infiltration from the inside surface. While negative side waterproofing can be more cost-effective in the short term, it comes with several disadvantages. One major drawback is the limited protection it provides, as it does not protect against external water pressure. Additionally, negative side waterproofing fails to prevent the corrosion of reinforcing steel, as water can still reach it. Interior waterproofing may also impact the design and finishing of interior spaces. Furthermore, water pressure constantly pushes waterproofing material away from the surface, significantly reducing its service life compared to positive side waterproofing.

Choosing the Right Method

Various factors, including building design, site conditions, budget, and water exposure influence the choice between the positive side and negative side waterproofing. Additionally, it's important to understand that chemical grouting allows for positive side waterproofing application from the negative side without excavation. The decision should be based on a thorough assessment of the building's needs in consultation with an experienced contractor.

Sealing Concrete Cracks in Basement Walls

Posted by Kreg Thornley on May 21, 2024 10:00:00 AM

Banner - Sealing Concrete Cracks in Basement Walls

Body - Sealing Concrete Cracks in Basement WallsAre you dealing with a damp basement due to leaking walls? Water seeping into your below-grade rooms can ruin living spaces, destroy stored items, and lead to mold growth. However, you can stop this problem by hiring a contractor trained in sealing concrete cracks.

What Causes Concrete Wall Cracks?

Several factors can cause basement wall cracks that allow water intrusion:

  • Imperfect construction: New homes often develop leaks if builders don't properly waterproof them
  • Aging concrete: Exposure to hot/cold cycles and general aging creates cracks over time
  • Unstable soil: Soil issues like erosion, poor compaction, and freeze/thaw cycles undermine foundations

While temporary surface repairs exist, polyurethane injection from the inside provides the best long-term solution. Depending on your situation, trained waterproofing contractors will likely use one of two methods.

Option 1 - Polyurethane Crack Injection

Polyurethane crack injection offers several advantages. Depending on the structure, contractors may be able to do it from either side of the wall, allowing the space to remain in use during repair. Additionally, the polyurethane material reacts with the leaking water to cure into a flexible seal (allowing for slight structural movement over time).

The Crack Injection Process

  1. Locate and prepare the crack surface
  2. Drill injection holes along the crack at an angle
  3. Flush the holes with water to remove debris
  4. Install injection ports and inject water to confirm the flow direction
  5. Inject polyurethane grout, normally starting at the lowest point
  6. Reinject grout a second time
  7. Inject a final round of water to reactivate any remaining grout

Contractors need about 1 gallon of grout per 25 linear feet of cracks. Although this process is straightforward, it's not a DIY or handyman project. Always consult a professional to ensure they use proper techniques and materials.

Option 2 - Polyurethane Curtain Wall Grouting

Curtain wall grouting involves injecting an entire wall or section with polyurethane to create a waterproof barrier. This method is ideal when a wall has numerous cracks that are difficult to locate and inject individually.

The Curtain Wall Grouting Process

  1. Drill a diamond-shaped grid of injection holes across the wall
  2. Beginning at the bottom, inject each hole with polyurethane grout
  3. Work up the wall, with each new row of grout flowing over the previous
  4. Continue until the entire area is sealed

The injected grout penetrates into the soil behind the wall, forming a water-impermeable curtain. Consequently, this "positive side" waterproofing stops the water at its source. As a result, it blocks any seepage from entering the wall.

Contractors pioneered this technique in the 1960s for leaking manholes, and it's effective on concrete, block, stone, brick, and even wood or metal. They often use it for basements with hard-to-find cracks, previously failed injections, or masonry walls unsuitable for individual crack injection.

The specific polyurethane grout used for a curtain wall depends on soil conditions, voids, and water volumes. Therefore, always consult with a waterproofing professional so they can choose the ideal grout and injection pattern.

Hiring a Professional Trained in Sealing Concrete Cracks

Both polyurethane crack injection and curtain wall grouting are highly effective when trained experts do them properly. With either approach, the injected grout creates a permanent, flexible water barrier that reacts with the leaking water.

Once professionals permanently seal the leaks, you can confidently use your below-grade room without worrying about future water damage. As a result, you'll enjoy your dry, comfortable space for decades to come!

Tunnel Leak Seal Series - 3. Leak Seal Methods

Posted by Charlie "The Grout Geek" Lerman on Nov 1, 2023 10:00:00 AM

Tunnel-Leak-Seal-Series-3.-Leak-Seal-Methods-Banner-Graphic-1400x425

Tunnel-Leak-Seal-Series-3.-Leak-Seal-Methods-Body-Graphic-800x1200After identifying tunnel leaks, the next step is exploring sealing methods. While crack/joint injection and curtain grouting are common solutions, they are not one-size-fits-all. By understanding the range of options and their pros and cons, engineers, maintenance teams, and infrastructure managers can make informed decisions tailored to each leak's unique circumstances. 

Crack/Joint Injection and Curtain Grouting: A Brief Overview

Before diving into alternative methods, let's briefly touch upon the two most commonly used techniques for sealing tunnel leaks.

Crack/Joint Injection

Crack/joint injection involves injecting a sealing material, often a polyurethane grout, directly into the cracks or joints where water is leaking. This method is highly effective for sealing small, accessible leaks and is often used in concrete tunnels.

Curtain Grouting

Curtain grouting involves injecting grout in a curtain-like pattern behind the tunnel lining to create a waterproof barrier. This method is more suitable for larger leaks or when the exact location of the leak is unknown.

Alternative Methods

While crack/joint injection and curtain grouting are effective, they are not always the best fit for every situation. Here are some alternative methods worth considering:

Mechanical Seals

Mechanical seals use physical components like gaskets, O-rings, or metal clamps to seal off leaks. These are often used in utility tunnels where pipes or cables pass through the tunnel walls.

Cementitious Grouts

Cementitious grouts are water-based grouts that can be used in wet environments. They are often used in combination with other methods to provide a more robust sealing solution.

Epoxy Resins

Epoxy resins are synthetic materials that can adhere to a variety of surfaces. They are particularly useful for sealing leaks in metal tunnels or in areas where a strong bond is required.

Swellable Waterstops

These are hydrophilic materials that expand upon contact with water, effectively sealing off leaks. They are often used in construction joints and are particularly effective in concrete tunnels.

Factors Influencing Method Selection

Choosing the right tunnel sealing method involves considering several factors:

Material Compatibility

The material of the tunnel lining plays a significant role in method selection. For example, cementitious grouts work well with concrete surfaces, while epoxy resins are more suitable for metal surfaces.

Severity and Location of the Leak

The size and accessibility of the leak also influence the choice of method. Crack/joint injection is more suitable for small, accessible leaks, while curtain grouting or mechanical seals might be better for larger or less accessible leaks.

Environmental Considerations

The surrounding environment can also influence method selection. For example, in tunnels close to natural water bodies, it's crucial to choose environmentally friendly sealing materials.

Criteria for Selecting a Tunnel Sealing Method

When choosing a sealing method, stakeholders should consider the following criteria:

Effectiveness

The primary consideration should be the method's effectiveness in sealing the leak and preventing future leaks.

Cost-Efficiency

While it's tempting to opt for the cheapest solution, stakeholders should consider the long-term costs, including maintenance and the potential need for resealing.

Regulatory Compliance

Different jurisdictions have varying regulations concerning tunnel maintenance and repair. It's crucial to choose a method that complies with these regulations to avoid legal complications.

Long-Term Sustainability

The chosen method should offer a durable solution that stands the test of time, minimizing the need for frequent repairs.

Key Takeaways

Sealing methods for tunnel leaks go beyond just crack/joint injection and curtain grouting. Various factors, including material compatibility, leak severity, and environmental considerations, influence the choice of method. By understanding these factors and criteria, stakeholders can make informed decisions that not only address the immediate issue but also offer long-term benefits.

Utility Tunnels

Utility tunnels house critical infrastructure such as electrical wiring, water pipes, and gas lines. Water leaks in these tunnels can lead to corrosion of pipes and electrical short circuits, posing both a safety risk and the potential for service interruptions.

Rail Tunnels

Rail tunnels are particularly sensitive to water leaks due to the electrical components and the high-speed nature of the trains. Water ingress can compromise the track bed, leading to uneven rail surfaces and, in extreme cases, derailments.

Subway Tunnels

Subway tunnels, often located underneath busy urban areas, are susceptible to water leaks from the surrounding soil and existing utility lines. Leaks can disrupt service, leading to delays and increased maintenance costs.

Vehicle Tunnels

Vehicle tunnels are prone to water leaks from both the tunnel walls and the roadway. Water accumulation can create hazardous driving conditions, leading to accidents and traffic jams.

Pedestrian Tunnels

Pedestrian tunnels, although generally less complex than other types of tunnels, are not immune to the problems caused by water leaks. Slippery surfaces can result in falls, and the damp environment can become a breeding ground for mold and bacteria.

Immediate and Long-Term Consequences

Understanding the consequences of water leaks in tunnels is crucial for grasping the urgency of this issue. Here are some of the most pressing concerns:

Structural Issues

Water leaks can weaken the structural components of a tunnel over time. The water can erode the material of the tunnel walls, leading to cracks and fissures that compromise its structural integrity. In extreme cases, this can result in partial or complete tunnel collapse, which would have catastrophic consequences.

Safety Risks

Water leaks create multiple safety hazards. In utility tunnels, electrical short circuits can occur when water comes into contact with electrical components. In vehicle and pedestrian tunnels, water accumulation can lead to slippery surfaces, increasing the risk of accidents. In rail and subway tunnels, water ingress can compromise the track bed, posing a derailment risk.

Operational Disruptions

Even minor leaks can cause significant operational disruptions. For example, subway services may need to be halted for emergency repairs, leading to delays and overcrowding. In utility tunnels, service interruptions can affect a wide range of essential services, from electricity to water supply.

Service Delays and Closures

Persistent water leaks often necessitate partial or complete tunnel closures for repair work. These closures disrupt regular services and can have a ripple effect on other parts of the transportation network or utility services.

Key Takeaways

Water leaks in tunnels are a pressing issue that affects various types of tunnels, each with its unique set of challenges and vulnerabilities. The immediate and long-term consequences of these leaks range from structural degradation and safety risks to operational inefficiencies and service disruptions. Addressing this issue requires a comprehensive understanding of the types of tunnels affected and the potential consequences of water leaks.

Grain Silo Maintenance Series - 1. Sealing Elevator Pit Leaks

Posted by Charlie "The Grout Geek" Lerman on Oct 23, 2023 10:00:00 AM

1. Banner - Grain Silo Maintenance Series - 1. Sealing Elevator Pit Leaks2. Body - Grain Silo Maintenance Series - 1. Sealing Elevator Pit LeaksGrain silos serve as the backbone of agricultural storage and supply chains. They hold not just grain but also the trust of farmers, suppliers, and consumers. One of the most critical yet often overlooked aspects of maintaining a grain silo is the integrity of its elevator pits. Leaks in these pits can lead to a cascade of problems, from grain contamination to equipment malfunction. Understanding the importance of sealing leaks in elevator pits, the risks of water ingress, and the role of polyurethane provides actionable knowledge for effective grain silo management. 

The Risks of Water Ingress

Grain Contamination

Water ingress in elevator pits poses a significant risk to the quality of stored grain. When water seeps into the silo, it creates a conducive environment for mold growth and bacterial contamination. These microorganisms can rapidly spoil large quantities of grain, leading to financial losses and potential reputational damage. Moreover, contaminated grain can pose health risks if it enters the food supply chain.

Fumigant Efficacy

Another less obvious but equally important concern is the impact of water ingress on fumigants used for pest control. A leaky elevator pit can dilute fumigants, reducing their concentration and effectiveness. This compromised state can lead to increased pest activity, further jeopardizing grain quality. Therefore, a well-sealed elevator pit is not just a structural requirement but also a critical factor in effective pest management.

Impact on Equipment and Operational Downtime

Equipment Malfunction

Water leaks don't just affect the grain; they also have a detrimental impact on the mechanical components housed in the elevator pits. These components, including conveyors and lifts, are essential for the efficient operation of the silo. Water can corrode metal parts, disrupt electrical systems, and cause premature wear and tear. The result is often equipment malfunction, which necessitates costly repairs or replacements.

Operational Downtime

The time required to address these malfunctions translates into operational downtime. For every hour the silo is non-operational, there's a cascading effect on the supply chain. During peak harvesting or shipping seasons, this downtime can be particularly costly. The financial implications extend beyond the immediate repair costs to include lost revenue and potential contract penalties.

Polyurethane as a Solution

Polyurethane Leak Seal Grout

Polyurethane stands as a highly effective material for sealing leaks in elevator pits. One of its primary advantages is its quick-setting nature. Unlike traditional materials like cement, polyurethane can set within minutes, drastically reducing the time required for repairs and, consequently, operational downtime.
Another advantage is its flexibility. Polyurethane can expand and contract with temperature fluctuations, maintaining a tight seal and offering long-lasting results. This characteristic makes it particularly useful in environments with extreme temperature variations.

Experienced Waterproofing Contractors

While polyurethane offers an effective sealing solution, proper application is critical to achieve optimal results. This is where the expertise of an experienced contractor comes into play. Look for a contractor who specializes in commercial waterproofing and has a proven track record with polyurethane grouts. They will have the right equipment, training, and techniques to thoroughly clean, prepare, and seal the problem areas. Rushing through the job or using improper methods can compromise the integrity of the seal.

A quality contractor will take the time to inspect, diagnose, and address the root causes of leaks before applying the sealant. They will also guarantee their work, which demonstrates confidence in their skills. While it may involve a slightly higher upfront cost, spending on an experienced contractor ultimately pays off through lasting results and minimized repeat repairs down the road. Their expertise in all aspects of the sealing process gives you the assurance of not just a quick patch-up solution but a robust, long-term fix to keep your elevator pits dry for years to come.

Proactive Maintenance is Key

Sealing leaks in elevator pits is not just a maintenance task; it's a critical operation that impacts grain quality, equipment functionality, and overall operational efficiency. Water ingress can lead to grain contamination, reduce the efficacy of fumigants, and cause equipment malfunction. These issues, in turn, contribute to operational downtime and financial losses.

Polyurethane offers a robust solution for sealing these leaks. Its quick-setting and flexible nature makes it an ideal choice for this application. The key takeaway is that proactive maintenance of elevator pits can prevent a multitude of problems. By understanding the risks and available solutions, silo owners and operators can make informed decisions that safeguard both their investment and the quality of the grain they store.

By addressing the issue of leaks in elevator pits, you're not just fixing a structural problem; you're enhancing the overall integrity and reliability of your grain silo. And in a business where margins can be thin, such proactive measures can make a significant difference to your bottom line.
