Cracks in poured concrete or concrete block, Stone, or Brick foundation walls can result from shrinkage, differential settlement, lateral pressure on the wall by the soil, or poor workmanship. It is not uncommon to find short cracks in the foundation walls. Cement block, Brick, and Stone foundations have a greater chance of water seepage then poured concrete foundations due to the numerous joints. We recommend all cracks be sealed as a precautionary measure against water and insect penetration. Since it is not possible to determine from a single visual inspection whether the cracks differential settlement is active or dormant, the wall should be checked for incremental movement over a period of time, usually several months or years.
