Slab Piers

slab piers

Slab piers are push piers designed specifically to stabilize and (in some cases) raise slabs that have settled. This type of pier is driven into the soil in the settlement area, deep enough to connect the slab to stable, load-bearing soil or bedrock. The helical blades anchor to the soil as the pier is essentially screwed into the ground. A specially designed bracket connects the top of the pier to the underside of the slab to stabilize and/or raise the slab back to its original position. Grout is pumped in to fill the void created under the slab, and then concrete is poured over the holes created for installation.

Advantages of slab piers:

  • Can extend to great depths to contact stable soil or bedrock
  • Non-destructive repair requiring minimal excavation
  • Completely hidden after installation holes are filled
  • In some cases can help lift a settled slab in addition to stabilizing i
