When the Slab Itself Is Sinking

Slab piers reach through the concrete you walk on and stand it on soil deep enough to ignore the drought and rain cycles that let it drop.

How it works

What to know about slab piers, and when it's the right call.

A slab pier turns the floor itself into a supported structure. The crew cores an opening through the concrete at each planned location and installs a steel pier beneath it, screwed in under logged torque, the twisting force recorded as proof of capacity, for helical piers or driven hydraulically for push piers, advancing until the readings prove the pier has reached soil that can carry its share of the load. A bracket assembly then connects the underside of the slab to the pier head. With every pier verified, the crew lifts the slab toward its original elevation, watching crack lines close and door gaps even out as it rises, then locks the connections so the slab bears on the steel. The result is a floor standing on strata far below the moisture swings of the surface clay. The cored openings are patched with concrete, leaving small, tidy circles instead of trenches through your home.

The symptoms that usually lead to slab piers are on the foundation repair problem signs page, alongside the other signs that point to the same underlying cause.

Installation Process

How we install slab piers.

Step 01

Free evaluation with elevation mapping

We measure floor elevations across the slab to map where it has dropped and how far, and separate deep settlement that needs piers from shallow voids that polyurethane lifting can solve.

Step 02

Pier layout

Pier locations are planned from the elevation map so the lift is even and the loads are shared, with pier type matched to the soil and access.

Step 03

Core and install

Small openings are cored through the slab, and each pier is driven or screwed beneath the floor until its readings verify capacity in stable soil.

Step 04

Lift and lock

The slab is raised toward level while the crew tracks elevations in real time, then locked to the pier heads so it bears on the steel.

Step 05

Patch and verify

Cored openings are patched flush, the site is cleaned, and final elevations are compared against the starting map so you can see the correction.

Diagnosis First

Does your floor need slab piers?

Slab piers are the deep fix for slab settlement. Whether yours is the deep kind is a measurement question.

Middle of the floor down, cause runs deep

Interior low zone, soil failed well below the slab

The defining slab pier case: core through the concrete, install steel to verified capacity in stable strata, lift the slab toward level, and lock it to the piers.

Concrete lifting · How it works

The slab comes back up.

Sunken concrete almost never means bad concrete. The soil under it washed out or compacted, and the slab followed. Filling that void lifts the slab back to where it was poured.

What happens at your home
01
Find the void. We map where the slab has dropped and what is missing underneath.
02
Drill small ports. Clean holes about the size of a coin, in a pattern that controls the lift.
03
Pump the fill. Polyurethane foam flows into the void and pressurizes gently.
04
Watch it rise. The slab returns to level in real time; ports are patched flush the same day.

Frequently Asked Questions

Answers to common questions about Slab Piers.

Don't see your question here? Our team is happy to help. Reach out anytime.

It depends on how deep the problem goes. Shallow voids and modest settlement usually respond to polyurethane lifting, which is faster and less invasive. Deep seated settlement, where the soil has failed well below the slab, needs piers that reach past it entirely. The elevation map from the free evaluation tells us which one your floor is dealing with, and we recommend the smaller fix whenever it will hold.
