How does the San Marcos River affect nearby home foundations?

Proximity to the river can lead to variable moisture levels in the soil, contributing to slab movement in surrounding neighborhoods.

What foundation issues are common in homes near Texas State University?

Many properties in this area experience settling from older construction combined with the region's hot summers and clay soils.

How do I know if my slab foundation needs repair?

Look for cracks in the slab, drywall or brick, doors and windows that stick, and floors that slope. One symptom alone does not always mean structural repair is needed, so an inspection is the best way to know.

What causes slab foundations to settle in Texas?

Expansive clay that swells and shrinks with moisture is the main cause. Plumbing leaks, tree roots and poor drainage can add to it.

Can a slab be lifted back to level?

Often, yes. Slab lifting or piers can raise settled sections, but how much improvement is possible depends on the slab and the amount of movement.

Slab Foundation Problems in Texas

Most Texas homes built since the 1970s sit on a concrete slab over expansive clay. The clay swells after heavy rain and shrinks during long dry spells, so parts of the slab can rise or drop unevenly. Over time that shows up as cracks in the slab or brick, doors and windows that stick, and floors that slope.
