Steel pier foundation repair.

If your slab has settled, the soil beneath part of it has moved — and any repair that doesn’t reach below that moving soil is temporary. Steel piers are GroundLock’s answer because they transfer your foundation’s load to a depth the clay can’t reach.

What steel piers are

A steel pier is a series of galvanized steel sections driven one on top of another, straight down beneath the foundation’s perimeter beam or interior pad. Unlike pressed-concrete piers, steel sections keep advancing until they hit a stratum dense enough to resist further driving — what engineers call refusal. That depth, not a fixed number, is where stable support lives.

Why steel — not concrete or hybrid piers

Pressed-concrete and hybrid piers stop at a preset depth, which in expansive-clay regions is often still inside the active moisture zone. Steel piers bypass that zone entirely. For slab foundation repair, GroundLock installs steel piers exclusively — it is the method that holds through Central Texas’ drought-and-downpour cycle.

• Depth to refusal — driven until they reach genuinely load-bearing soil, not a guess
• Engineered load transfer — your home rests on steel, isolated from clay movement
• Verifiable — drive force is logged at every pier; elevation re-surveyed after lift
• Lifetime transferable warranty — protection that follows the home to the next owner

Signs you may need it

• Doors and windows that stick, drag, or won’t latch
• Stair-step cracks in exterior brick or block
• Sloping or bouncy floors; a slab that feels “off”
• Cracks in drywall radiating from door and window corners
• Gaps opening between walls, trim, and the ceiling
• Visible separation in the slab or at the garage floor

Protecting the repair

Because water drives soil movement, lasting results often pair stabilization with drainage correction, erosion control, or regrading. We only recommend what protects your foundation — explained plainly, tied to the problem we measured.
