Does Your House Have Cracks?

Cracking of walls and slabs is a common problem in the Pikes Peak Region. Much of the soil here is expansive clay that will move to some extent based on the moisture content of the soil. This can cause cracks that range from merely cosmetic to extremely detrimental to the structural integrity of the house. Cracks in slabs, for example, tend not to be critical. The same can be said for small vertical or horizontal drywall cracks and hairline vertical cracks in foundation walls. Horizontal foundation cracks or large vertical or diagonal foundation cracks are more concerning. Determining the severity of the crack is where a trained engineer can help. Some examples of different cracks and their severity are shown below.

Diagonal cracks from the corner of the window have been previously sealed and have reopened, showing ongoing movement of the structure. Structural repairs are probably necessary.

Horizontal cracking of the basement wall indicates excessive pressure behind the wall and the need for repairs.

Minor hairline drywall cracks (left) are rarely significant, but bulging of the drywall (right) is a sign of significant structural settlement.
