Post Oak Savannah
Foundation Repair in Henderson County, Texas
Between the Blackland Prairie and the East Texas forests — Bryan-College Station, Bastrop, Palestine, Athens — lies the Post Oak Savannah. Its typical soils (Alfisols such as the Axtell, Crockett and Wilson series) have a loamy or sandy surface over a dense, very slowly permeable clay subsoil: the local "claypan." That subsoil is genuinely expansive even though the surface looks sandy, which surprises homeowners who assume they don't have clay problems.
Deceptive profile: modest-looking sandy surface over a high shrink-swell claypan subsoil — movement originates below the topsoil where moisture changes arrive slowly but hold long. Across Henderson County's communities that plays out the same way: because the claypan wets and dries slowly through the sandy cap, movement often lags the weather: settlement or heave shows up weeks after a drought breaks or a wet spell ends, and perched water on the claypan aggravates one side of a foundation.

What Henderson homeowners deal with
- Shrink-swell of the dense claypan subsoil beneath sandy surface layers
- Perched water sitting on the claypan after wet spells, softening one side
- Post oak roots drying the subsoil unevenly around older homes
- Fill settlement where pads were built up over the native profile
Piers must pass through the claypan to stable material below; both pressed and steel piers are used. Gutter, grading and subsurface drainage work address the perched-water side of the problem.
