A crack near the basement window allowed water into the home. We used our patented FlexiSpan System to seal the crack. . First we seal the crack with a high-viscosity polyurethane polymer. This gets deep in the cracks to form a durable, flexible seal. The polymer seal should never fail. If it ever does, 95% of the water should still be stopped from leaking in. To ensure a proper repair, we install a secondary layer of drainage on the basement wall -- one that will direct water to your basement drainage system or dry well. To keep your foundation walls looking great, we overlay your sealed wall crack with a polyurethane sealant. After the wall crack has been repaired, the concrete floor is restored flush, with no gaps or openings.
