Basement Waterproofing - Why FlexiSpan® over Injection?
Unlike hydraulic cements and some epoxies, the special sealant used for FlexiSpan® will never dry out or re-crack over time.
Additionally, hydraulic cements, epoxies, and even urethane injections are not able to bend and stretch along with your foundation movement. As concrete walls expand and shrink slightly through freeze/thaw and wet/dry cycles, the bonds of these materials will fail and the crack will releak.
FlexiSpan® stays bonded with wall movement, and seals the crack permanently, no matter what.
