If you hired a contractor and a couple of years later your wall looks like this, your wall is still moving and the products used are inadequate. Polyurethane Injection. ... The method we use is called polyjacking, a high-density polyurethane injection foam, that is injected into a small 5/8” hole drilled through the affected concrete every 6" to 8". This high-density polyurethane foam expands 20 times its liquid volume as it moves laterally beneath the pavement filling all voids. #900 Hydro Sealant. #900 Is A Single Component Hydrophilic Polyurethane Chemical Grout. When It Comes In Contact With Water It Quickly Expands To Form A Tough, Flexible, Closed Cell Foam Which Bonds Extremely Well To Concrete. When Cured It Becomes An Extremely Effective Barrier Against Water Penetration.Applications:- Basement Cracks- Manholes- Swimming Pools- Tunnels- Cold Joints Benefits:- Single Component [No Catalyst Required]- Extremely Flexible- Very Tough Foam- Up To 700% Expansion- Penetrates Pores Of Concrete For Superior Bond For Foundation cracks, basement leaks and basement waterproofing in the Kansas City ares MO and KS
Once we inject the Polyurethane foam into the crack we seal the surface crack with a hydraulic water stop cement or fast drying epoxy coating. This stops the water from entering in the original crack.
