Our experienced and skilled technicians know that a basement with a leaking wall crack is harmful to your home. Generally, this is caused by concrete shrinkage, foundation movement, or hydrostatic pressure pushing the walls in. Soil contraction and expansion can cause further foundation cracks and separation. Thus, giving your home a sizeable crack in the foundation wall. Once a crack is in the wall, multiple issues can occur. These issues could include water intrusion, mold and mildew, and pest infestation.
