Dallas/Dallas County: Three major rock formations run underneath Dallas county with the western third of the county underpinned by Eagle Ford shale, which produces a variety of expansive clay soils.

Fort Worth/Tarrant County: Two major rock formations trend in a north-south orientation, however, there’s where the similarities end. Fort Worth is comprised mostly of rocky soils with small pockets of clay soils in between

Harris County: This is home to Houston and surrounding cities such as The Woodlands, Sugarland, and Katy. The coastal geology here is different from the rest of Texas, and thus requires a specific approach to foundation repair.

San Antonio/Bexar County: Two of the rock formations that define this area are a limestone-shale sequence. This is often referred to as “layer cake geology”, which produces clay-rich soils with very shallow soil horizons.

Austin, Georgetown and Travis County: This region is underpinned by formations that run north to south much like Dallas and Tarrant counties. The soil horizons here are typically shallow and rocky. Clay content of the soil is high.

Foundation repair—especially in Texas—cannot be approached with a single-solution mindset. Texas soils are just too unique and varied. Without first understanding the soil your foundation sits on, recommending the right foundation repair is impossible.

That’s why you should put your trust in the dirt nerds of Texas.
