How Expansive Soil Affects Your Foundation: What Causes Foundation Cracks — Hendersonville?
Rain, snow, or plumbing failure can result in wet soil. And when expansive soil gets wet it swells considerably, adding 10% or more in volume. This puts additional hydrostatic pressure on the outside of your foundation walls, to the tune of around 20,000 pounds per square foot. Without any preventative measures, your foundation walls could bulge, bow, crack, tilt, or even collapse altogether. This type of wall damage can also increase your risk of water infiltration and other hazards.
Expansive, clay-heavy soil not only grows when wet but also shrinks as it dries. During dry seasons, your soil could contract enough to cause erosion, air pocket formation, and structural shifts in your home. In climates like the one we have here in Hendersonville, repeated wet and dry cycles can cause additional wear and tear on foundations.
