Slab Foundation Settlement Repair

Slab Settlement Repair

Floor cracks are a major sign of slab sinking and settlement.

Concrete slab foundation settlement is often the result of changes in moisture content and density of the soils beneath the slab. For example, soils beneath a concrete slab can dry and shrink over time due to extended drought-like conditions or leaking HVAC systems. Loosely compacted fill soils can also consolidate beneath a slab causing floor cracks, tripping hazards and other cracking and settling throughout a home or building.

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. Check out our page on what causes slab settlement issues for more information.

Don't wait for the problem to get worse. Contact a Foundation Supportworks dealer to schedule an appointment for a free evaluation of your property today.

Slab Pier Advantages:

  • Can be installed year-round
  • Deep pier installation extends beyond unsuitable soils
  • Non-invasive - small holes are cored in the slab and patched afterwards
  • Can lift slabs and partition walls back to original, level position
  • Long-term solution
  • Restores property value

The Foundation Supportworks Slab Pier System 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:
