Cracks in foundation walls usually occur because of shrinking, swelling or soil settling. Cracks typically appear at the weakest points in the foundation walls such as windows, beam pockets and changes in wall elevations. Abalon recommends crack repair from the exterior only using compressible materials. Crack repair from the inside, leaves a space on the exterior side of the foundation wall allowing water to continue collecting. As the water freezes, it opens the cracks again.
