A settling concrete slab can cause extreme structural problems in your home. Concrete slab settlement is often the result of changes in the soils beneath the slab. Soils beneath a concrete slab can dry and shrink over time due to extended drought-like conditions or leaking HVAC systems. Unstable soils cause floor cracks and settling throughout your home. These conditions and others, create a void under a slab. If the slab isn't strong enough to span the void, the slab will crack, break, and settle into the void.
The Foundation Supportworks Slab Pier System installed by Thrasher Basement Systems can stabilize concrete floor slabs and provide the best opportunity to re-level the floor and lift any non-load bearing partition walls that may have settled along with the slab. Rugged steel pier sections are hydraulically driven through a heavy-duty slab bracket to reach competent, load-bearing strata. The weight of your concrete slab floor is then carefully transferred from the original unstable soil, through the piers, to competent soils below.

Slab Pier Installation Steps:
![]() Step 1: A small hole is drilled through the concrete floor. |
Step 2: The slab bracket is positioned beneath the concrete slab. |
Step 3: Steel tubes are hydraulically driven down through the bracket to stable soil. |
![]() Step 4: The weight of the slab is transferred through the piers to load bearing strata. The slab is lifted back to level if possible. |
Step 5: Grout is carefully pumped under the slab to fill the void created by the settlement and slab lifting process. |
![]() Step 6: Concrete is placed within the cored hole. |
