First, the crack was sealed with a bead of special flexible sealant that will slow and, in most cases, stop the flow of water through the crack. This photo shows step 2 (since the sealant is not visable). Next, a 3 1/2" wife strip of beveled FlexiSpan open cell foam is applied over the sealant and tucked into our waterproofing system on the floor.
*A FlexiSpan can drain to WaterGuard or a drywell if there is no drainage system in place
