Foundation Underpinning
Underpinning stabilizes foundations by transferring the load to deeper, more stable soil layers and bedrock, using QFR's steel push pier or Adjust-A-Pier systems depending on foundation type.

What to Know About Foundation Underpinning
Underpinning is one of the most direct ways to stop foundation settlement: rather than treating the surface symptoms, it extends the foundation's support down past the reactive soil layer to strata that doesn't move with Central Texas's wet-dry cycles. It's typically recommended when an inspection shows settlement is ongoing and shallow repairs won't hold.

Expansive Soil
Central Texas's expansive clay soil swells when wet and shrinks when dry, the number-one cause of foundation movement in the area. It's predictable, and it's fixable.
Learn moreFoundation Underpinning and Central Texas Clay
Austin's expansive Blackland clay shrinks in dry summers and swells after rain, cycling in volume with every wet and dry season. Homes built on this clay can experience ongoing movement as the soil expands and contracts. Where that movement shows up depends on the home and foundation type.
