The common method of repairing basement wall cracks involves injection of a polyurethane material that generally will fail over time due. This material dries into a firm substance that can't move with a wall. Since concrete naturally shrinks and is subject to pressure from soils, it's essential to have a crack repair system that can work with the wall's movement. FlexiSpan® is the ideal solution to this problem. This flexible sealant is made of open cell foam and waterproof sealant.
FlexiSpan® is designed to move with a wall, ensuring that the entire crack is sealed even if there is a change in the wall. This is a permanent solution that installs smoothly over a wall, and its neutral color will fit with a concrete wall. FlexiSpan® can easily be covered up with a basement finishing product as well.
