Push Piers: Stabilizing and Lifting Sinking Foundations

Both are steel pier systems that carry a foundation's weight down to stable soil, but they install differently. Push piers are driven straight down hydraulically, using the weight of the structure as the force that pushes them to depth, so they work best under heavier loads. Helical piers are screwed into the ground like a large screw and can be a better fit for lighter structures or certain soil conditions. During your inspection we explain which system suits your home and why, rather than defaulting to one.

Often they can recover a meaningful amount of the settlement, and lifting the foundation can help close cracks and bring doors and windows back into alignment. The honest answer is that the practical lift depends on the structure, how it has settled, and the soil conditions. We aim for the best achievable result and stabilization against future settling, and we are realistic with you about what is reasonable for your specific home instead of promising a perfect return to level.

There is no single number, because the right depth is wherever firm, load-bearing soil or bedrock is for your site. Across the Piedmont and the SC Upstate, push piers are designed to reach past the active clay layer that swells and shrinks with the seasons, since that upper soil is the source of the movement. In Sandhills sandy soils the depth to stable bearing can differ again. The piers are driven until they meet the resistance the engineering requires, which is what tells us they are seated on soil that can hold the load.

That is exactly what they are designed to do. By transferring the load onto stable soil or bedrock well below the active upper soil, push piers take the foundation off the layer that was moving. Because managing water around the home protects that result, we often recommend grading or drainage corrections as well, and we go over those during the inspection so the stabilization holds up over time.

Cost depends on the number of piers required, how deep they have to be driven to reach stable soil, access to the foundation, and the soil conditions at your home, along with whether any drainage or grading work is recommended alongside the piers. Because those factors vary from one home to the next, we provide pricing after a no-pressure inspection rather than a flat number online. The inspection is how we give you an accurate, honest quote for your specific situation.

The work is focused at the pier locations along the affected foundation, where we excavate down to the footing, install the piers, and then backfill and clean up the area afterward. It is a structural repair, so there is digging involved, but it is targeted to where the piers go rather than spread across the whole property. We walk you through what to expect at your home during the inspection.
