This homeowner reached out to us with a pressing issue concerning their sinking concrete walkway, which was causing concerns about water seeping into the foundation of their home. Recognizing the potential risks associated with this situation, we swiftly took action to provide a solution. Our skilled team utilized Polylevel foam, a cutting-edge technology, to raise and level the concrete, effectively filling any voids beneath. This not only addressed the safety concerns but also ensured that water wouldn't find its way into the foundation through the cracks. To further enhance the appearance and longevity of the walkway, we sealed the cracks using Nexus Pro.

Job Stories From Olathe, KS
Water in the basement in Olathe, KS

These homeowner had installed a French Drain nearly 15 years ago. They noticed recently the side of house was getting water inside, and imagined the drain was clogging. They called Thrasher because they knew we would be able to find a permanent solution. System Design Specialist, Tom Studer, came out to meet with them. After the inspection, Tom found water was going in through the cold joint in the basement, along with a couple of cracks in the wall. Tom decided the best solution to this issue would be to install our waterproof system. This includes WaterGuard and Cleanspace along the wall to efficiently capture the water that was coming at the cold joint and the walls. Cleanspace is a plastic, waterproof shield that is attached to the walls. When the water comes in, the Cleanspace is a barrier between the wall and the basement. The water trickles down and into the WaterGuard. WaterGuard is our drainage channeling system. Once the water enters WaterGuard, it flows to the sump pump and out of the home! Tom discussed this with the homeowners and we got started! These homeowners were so happy to know there will not be anymore water issues in their home!
