Bowing Basement Wall Repair in Sparta, Michigan

You’re spending time in your basement den, and you wonder if your eyes are playing tricks on you. Is that basement wall straight, or is it curved?

Bowed Basement Walls Are a Common Problem

Basement walls bow in when there is too much lateral pressure pushing on the foundation of your home. Basement walls were designed to support vertical loads from the weight of your house. When the soil surrounding your home expands and contracts, it exerts horizontal pressure on your basement walls – and sometimes the pressure is too much for the wall to withstand. This pressure can cause your walls to bow in or even to slide in at the top or bottom.

Bowing basement walls are important to fix in order to make your home safe and usable. Cracks in the block wall lets moisture and insects into your basement. In the following case inward wall movement made finishing this basement with framed rooms, very difficult.

He contacted Kent Foundation Repair for an estimate and repair plan. We recommended installing 8 earth anchors to stabilize the walls and pull them back into position.

As we began installation, we found the best solution was to switch to 6 helical tiebacks in order to overcome extensive rubble and reach more competent soils outside the perimeter of the home.

These steel plates are attached to helical piers installed through the basement wall at a downward angle into the outside soil. In order for this process to work well, the piers need to be drilled into solid soil.
