Before & After
FlexiSpan crack repair is actually a three-part process that begins with the application of a flexible sealant along the full length of the crack. Next, a strip of flexible and porous foam is installed over the crack. Finally, an impermeable membrane is adhered to the wall on both sides of the foam strip. This fail-safe treatment allows any future seepage of water through the crack to move invisibly down the wall and into the basement’s perimeter drainage system. Unlike sealant or mortar-based crack repair, the FlexiSpan system is not adversely affected by hydrostatic pressure or slight movement in the basement wall. It works under all conditions.
