Soil Stabilization

Most foundation movement in Central Texas traces back to the soil underneath it: expansive clay that swells when wet and shrinks when dry. A repair that doesn't account for that movement is working against it.

Soil stabilization treats the soil itself so it moves less through those cycles. QFR scopes it as part of your repair plan and manages a specialist partner who performs the soil work; where the foundation has already settled, our own crews pair it with steel push piers or Adjust-A-Piers driven to soil that doesn't move.

The soil is treated by injection rather than excavation. A soil stabilizer is injected in two passes, every 3 to 4 feet around the perimeter of the foundation, to a depth of 10 feet or until the injection reaches material it cannot penetrate. Water must be available on site through a hose bib.

QFR guarantees to lower the potential vertical rise, which is how far the soil under the foundation could push upward as it takes on water, to 1 inch or less, or the soil's swell to 1 percent or less. That guarantee applies only when a geotechnical engineer has tested the soil after the injections are complete. A geotechnical laboratory test is available on request.
