Cracked Poured Wall

Foundation walls can sometimes be damaged by soil pressure. In some cases, the soil's weight is simply too great to be held back by the foundation wall. In other cases, soil with high clay content expands during wet weather, exerting additional pressure against foundation walls. Whatever the cause, there are several telltale signs of foundation wall damage.

Do your walls need repair?

Cracked and bowing basement walls can develop immediately following construction or years later as changes occur within the soils that surround your home. These cracks aren't just unsightly - they compromise the structural integrity of your home.

How did this happen?

Soil pressure

The soil around your home puts a lot of pressure on your foundation walls. The amount of pressure varies depending on the type of soil near the home, the amount of moisture in the soil, and how deep the foundation is under the ground. There is nothing on the inside of the basement walls pushing back, to counter this pressure.

Hydrostatic pressure

When the soil around your house becomes saturated with water from heavy rains or water leaks, the water exerts additional pressure against the walls.

Frost

In areas with cold winter climates, frost can put pressure on a wall and cause it to fail, especially if the basement is unheated. Frost forces can be extremely powerful and can even lift shallow foundations up out of the ground, causing significant damage to the home.

Expansive clay soil

Clay is a common soil type in many areas. It expands and contracts as the amount of moisture in the ground increases or decreases. When you see dirt with cracks at the surface during a dry spell, this is what you're actually seeing - clay soil shrinks when it gets dry. When it rains and the clay soil gets wet it expands. This increase in size puts a lot of pressure on your basement walls. When the pressure is more than the wall can handle, the wall begins to push inward.
