crack-repair-baltimore Repairing a non-structural crack is pretty easy and relatively inexpensive but requires the services of a waterproofing professional/company. The technician cleans out the crack and inserts a number of plastic injection ports along its length. He then applies a surface coat of fast-drying epoxy to cover the crack and hold the ports in place. One the epoxy has cured, he injects each spot with expanding polyurethane, which fills and seals the crack all the way to the outside soil while remaining flexible when cured to prevent re-opening of the crack from minor foundation movement.

After the polyurethane has cured, the ports and epoxy can be scraped off the wall.

Fixing a structural crack is a somewhat bigger job. If the damage is spotted before the wall has moved significantly, it can be repaired with carbon fiber strips. Proper placement is determined by engineering data and the wall is ground smooth in spots where the carbon fiber is to be applied. Technicians apply a coat of industrial epoxy and embed woven strips of carbon fiber in the epoxy, using a roller to ensure a complete bond.
