The basement of this Killingly, CT home had cracks in its foundation walls. These were not causing any structural damage, but they did allow groundwater to enter the basement, seen in staining on the walls. We installed our FlexiSpan Foundation Crack Repair System to seal the walls. Our unique polyurethane sealant gets deep into the wall to form a durable seal. It will not dry out or re-crack over time and will remain flexible to move slightly with the wall's natural shifts.
