As a homeowner, discovering a leak in your concrete slab can be a stressful and frustrating experience. Left untreated, slab leaks can lead to sinking concrete and structural issues. Fortunately, there is a highly effective solution: slab leak repair with curtain grouting.

What is Curtain Grouting for Slab Leaks?

Curtain grouting is a process that involves injecting a water-reactive resin underneath the concrete slab in a grid pattern. The injected resin reacts with the water underneath, forming a solid, durable seal that prevents further water infiltration. This method is particularly useful when the exact location of the leak is difficult to pinpoint or when multiple leaks are present. In addition, residential slabs are often not thick enough for standard crack injection methods.

How Does the Slab Leak Repair Process Work?

• Injection Holes: Small holes are drilled through the concrete slab in a diamond grid pattern, allowing access to the soil beneath.
• Grout Injection: As the resin is injected into each hole, new injections begin overlapping the previous injection areas like shingles on a roof. This is referred to as stage grouting.
• Leak Sealing: The injected resin reacts with the water from the leak, expanding and forming a watertight seal that prevents further water intrusion.

Benefits of Curtain Grouting for Slab Leak Repair

• Comprehensive Solution: Curtain grouting addresses multiple leaks simultaneously, providing a complete repair without the need to locate each individual leak.
• Long-Lasting Results: The water-reactive resin forms a durable, flexible seal that withstands the test of time, offering long-term protection for your home.
• Minimally Invasive: Compared to traditional methods, curtain grouting requires minimal equipment and creates less disruption.
• Environmentally Safe: The products used in curtain grouting, such as Spetec PUR H100, H200, HighFoamer, and AG200, are NSF-certified for contact with drinking water (NSF/ANSI/CAN 61), ensuring a safe and eco-friendly solution.
