Foundation piers can stabilize a settling foundation, and some projects may allow the contractor to recover part of the lost elevation when conditions permit. The main goal is to transfer the structure’s load to stronger material deeper underground so the foundation no longer relies on the unstable soil that caused it to settle.

Foundation piers extend below unstable or weak surface soils until they reach soil or bearing material that can support the structure more effectively. The pier system then transfers the foundation load downward, helping stabilize areas that have settled or shifted.

The number of piers, installation depth, foundation access, soil conditions, landscaping, and amount of settlement all affect the schedule. A foundation inspection gives the contractor the information needed to determine the repair layout and provide a more useful project timeline.

Push piers use the weight of an existing structure as resistance while hydraulic equipment drives steel pier sections toward suitable load-bearing material. Helical piers screw into the ground using hydraulic torque, which can make them useful for lighter structures such as porches, decks, additions, and some garage slab foundations.

A home may need piers when foundation settlement causes sinking areas, growing cracks, uneven floors, sticking doors or windows, or other movement that points to inadequate support beneath the foundation. An inspection should first confirm the cause, because cracks and uneven floors can develop for reasons that don’t require pier installation.
