Ever see those large cracks Expansive soils cause crack in the ground during dry weatherin the ground and wonder why they are there? How did this occur? Was there an earthquake? The answer is no. These cracks are caused by expansive soils. The soils are found throughout the United States and can cause significant damage to a structure’s foundation. During dry seasons, the expansive soils shrink causing these cracks to form and foundations to settle. These soils can also swell when there is excess moisture and cause upheaval of a structure. Settlement cracks in brick can be initial indicators of foundation settlement during a drought season. Other signs are identified by sloping floors, cracked sheetrock, and uneven doors.
