If you have a crack in your foundation that is from hairline up to three-eighths of an inch wide, the repair method is pretty common across the board. The first step is cleaning the concrete so there is no paint, plaster, dirt or anything that would compromise the epoxy from adhering to the wall.
Next a layer of epoxy is spread along the crack with plastic ports placed at appropriate distances where the filling material will be injected. After the epoxy dries, either urethane or epoxy is injected starting at the bottom. After the material appears at the next port up the wall, the lower port is capped and the injection continues like this all the way to the top of the wall.
