When owning a basement with a poured concrete foundation, it is typical to find cracks in the foundation walls. Often these fractures, or cracks, open wider over time due to hydrostatic pressure. Hydrostatic pressure means applying an excessive weight load to the foundation wall laterally. When water sits outside the foundation wall it makes the dirt much heavier which can open these cracks up larger, and at this point, the cracks begin to allow water to pass through. Typically, these fractures will be widest at the top of the wall and taper as they approach the footing. This is due to the bottom of the wall being structurally tied to the footing and not allowing as much movement in the foundation wall.
