Bowing, buckling, and cracking walls indicate foundation failure.

Wall Repair for Cracked and Bowing Walls

What Causes Wall Failure?

There are a number of potential causes of cracked and bowing foundation walls, the most common reason is pressure from the soil near the outside of the wall. When clay soils get wet, they expand and put pressure on the wall. When the force exceeds the strength of the wall, and when the wetting cycle is repeated, this causes further weakening and inward movement.

Other factors include heavy rains (causing hydrostatic pressure) and other structures (i.e. driveways, porches) putting pressure on the wall, large tree root systems, expansion due to frost, and poor grading.

Symptoms of Bowing Walls:

Symptoms of bowing walls with a block foundation can include horizontal cracks in mortar joints, stair-step cracks at outside corners, horizontal shearing at the bottom of the wall and tipping at the top of the wall. In some extreme cases you may witness more than one or all of these symptoms and may even notice foundation walls that are bulging and have cracks all throughout the wall. If this is the case, the wall may be on the verge of a collapse.

Symptoms of a bowing or leaning wall with a poured foundation most often include the tipping of the wall, diagonal cracks at outside corners, and vertical or horizontal cracks in the wall.

Foundation walls can sometimes be damaged by soil pressure. In some cases, the weight of the soil 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 extra pressure against foundation walls. Whatever the cause, there are several telltale signs of foundation wall damage.

Our Solution For Bowing, Buckling Wall Repair

Foundation walls are designed to provide a solid base for the structures above them. When foundation walls begin to crack, bow, or tip inward, they can no longer provide adequate support for a structure.

Retaining walls are designed to resist the lateral earth pressures that are exerted against them, but factors such as hydrostatic pressure, frost and expansive clays can overstress the walls and cause them to crack or even collapse.

If you’ve noticed signs of a failing foundation or retaining wall such as a leaning, bowing or cracking wall, contact our experts to diagnose the problem and recommend a solution.
