The Bowline is an iconic 16-story apartment development located in the Wickham suburb of Newcastle, Australia. There is a secant pile constructed wall system in the basement of this new building. However, an issue arose during the drilling process, where the overlaps were not interlocked correctly, resulting in voids and substantial leaks. This situation posed a risk of sinkhole formation under the main road, the light rail system, and neighboring properties. Furthermore, it led to the accumulation of a substantial water pool within the construction site, impeding further excavation efforts. Geotech contractors The Injection Experts AU were called in to solve the problem.

Powerful Polymers

The following materials were chosen for the project: AP Fill 720 was selected for full curtain injection behind the secant pile wall system to stabilize and seal the voids and leaks. Oakum was chosen to plug large voids and gushing leaks due to its ability to quickly stop high-flow water intrusion when soaked in resin. Spetec AG200 was chosen for injecting minor leaks because of its ability to penetrate and seal hairline cracks.

Painless Procedures

AP Fill 720 was pumped through an Alchatek PolyShark pump into 1.1m x 13mm injection rods. This was done to fill the voids left by escaping sand and water and to create a waterproof barrier on the back side of the secant piles. Oakum, soaked in resin, was packed into voids and large holes. This measure aimed to slow down the ingress of sand and water into the basement while excavation and injection processes were ongoing. Spetec AG200 was injected through 13mm packers to seal any fine hairline cracks and to provide touch-up sealing around the injection rods.

Rapid Results

The repair efforts were ultimately a success. Through the strategic use of polyurethane grouting methods, the voids and leaks in the secant pile wall system were effectively sealed. This meticulous process not only waterproofed the basement area but also mitigated the risk of sinkholes forming under the nearby road, light rail, and neighboring lots. As a result, the project was able to proceed safely without further excavation issues, marking a triumphant conclusion to a challenging endeavor.

Does leaking or sunken concrete plague your basement floor? These issues can be more than just a nuisance; they can lead to serious structural problems if left untreated. In this article, we'll explore two effective methods for basement floor repair: curtain grouting for leaks and slab lifting for sunken concrete. With an understanding of these techniques, you'll be equipped to find the right repair professionals to restore a safe, dry, and level basement floor.

Sealing Slab Leaks with Curtain Grouting

As a homeowner, discovering a leak in your basement's concrete slab can be stressful and frustrating. However, contractors trained in curtain grouting offer a highly effective solution. This process involves injecting a water-reactive polyurethane foam underneath the concrete slab in a grid pattern. The material reacts with water, forming a solid seal that prevents further water infiltration.

The curtain grouting process begins by drilling small holes through the concrete slab in a diamond grid pattern. Next, technicians inject the polyurethane through each hole, with new injections overlapping the previous ones, a technique called stage grouting. As the foam reacts with the water from the leak, it expands and forms a watertight seal.

Benefits of curtain grouting with polyurethane:

• It addresses multiple leaks simultaneously, providing a comprehensive repair.
• The water-reactive resin forms a durable, flexible seal that lasts.
• It is minimally invasive, requiring less equipment and causing minimal disruption.
• The products used are NSF-certified for contact with drinking water, ensuring a safe and eco-friendly solution.

Leveling Uneven Basement Floors with Slab Lifting

In addition to sealing leaks, basement floor repair often involves leveling uneven or sunken concrete slabs. Uneven floors can be a tripping hazard and may indicate underlying structural issues. To level a basement floor, professionals commonly use a process called slab lifting.

Slab lifting involves pumping a polyurethane foam beneath the sunken portion of the slab. The foam expands, filling the void and lifting the slab back to its original position. This process is relatively quick and cost-effective compared to replacing the entire slab.

The polyurethane slab lifting process typically includes the following steps:

1. Technicians drill small holes through the concrete slab to access the void beneath.
2. They pump the polyurethane foam through the holes, filling the void and lifting the slab.
3. They patch the holes and smooth the surface, restoring the basement floor to a level and even condition.

Benefits of slab lifting with polyurethane:

• It is lightweight, reducing the risk of further soil compression.
• The foam expands quickly, allowing for fast lifting and leveling of the slab.
• Polyurethane foam is water-resistant, helping to prevent future moisture-related issues.
• The process is less invasive and more cost-effective than replacing the entire slab.

Concrete 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.

Construction 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.
