The soil surrounding your home may look innocuous, but it can actually be a major threat to the stability of your foundation. Expansive soil is typically rich in clay, which easily takes on moisture and can exert tremendous hydrostatic pressure which can result in a host of structural issues. United Structural Systems is a trusted leader for foundation reinforcement and repair in Brentwood, and we’ve seen the problems these soils can create. We have reliable, effective solutions for expansive soil in Brentwood that you can count on!
How Expansive Soil Affects Your Foundation
When expansive soil in Brentwood gets wet, from either precipitation or flooding, it can increase in volume by 10% or more. When this happens, the pressure from the soil against your foundation walls can increase, on average around 20,000 pounds per square foot. This inward pressure will cause your walls to bow, bulge, tilt, or crack, and put your house at risk for water infiltration which could even result in total foundation collapse unless you have the right reinforcements in place!
Not only does expansive soil grow when it comes in contact with water, it also contracts when it dries out. And this dryness will also cause structural shifts in your home and may lead to the formation of air pockets and erosion in the soil. Plus, repeated wet and dry cycles throughout the years can cause additional wear and tear from expansive soils on your Brentwood foundation.
