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.
Water Leaking into basement through wall crack
The Crack is cleaned and sealed.
Strip of flexible and porous foam is installed over the crack
Foam-lined channel directs water leakage to the waterproofing system.
Drainage Pocket
A drainage pocket is made at the footing and filled with aggregate.
Sealant is applied over the Foam
This fail-safe treatment allows any future seepage of water through the crack to move invisibly down the wall.
