FlexiSpan Poured Wall Crack & Leak Repair
FlexiSpan® is a patented crack repair system available exclusively from Basement Systems. Developed after years of research, the FlexiSpan system is an alternative to epoxy injection, another crack-sealing technique sometimes used by contractors.
Epoxy injection provides only a single line of defense against water leakage through a foundation crack, and this can fail if the crack moves slightly –which often happens.
FlexiSpan provides two lines of defense: a crack sealant and a hidden, low-profile drainage channel that directs any leaking water to your sump pump. The drainage channel is permanently sealed to the foundation, and can flex in response to wall movement.
Even if the polyurethane seal fails, it should stop 95% of the water that would otherwise come through the crack- the foam strip will not become overwhelmed with the minor seepage that might have made it through.
The low viscosity of our polyurethane polymer allows it to easily fill hairline cracks. It’s an affordable, effective and permanent crack-sealing technique.
