Bowing Basement wall- Helical Wall Anchor System

Concrete walls become stressed due to both horizontal and lateral earth pressure. This pressure mixed with water in the soil creates hydrostatic pressure. Poor foundations and those located in areas of weak or expansive soils, like clay and rock, eventually give to the pressure and begin bowing inward. If your foundation or basement wall is showing signs of bowing or bulging, this is a very serious foundation problem that can result in structural damage to your home.
