Repair Methods
Helical Piers for Foundation Repair
The short answer
Helical piers are steel shafts with helical plates that are screwed into the ground until they reach load-bearing soil, then used to stabilize and lift a foundation. They install with minimal vibration, work well in inconsistent soil and for lighter structures, and typically cost $1,500–$3,000 per pier installed.

What a helical pier is
A helical pier is essentially a large steel screw: a shaft with one or more helical plates that’s turned into the ground with hydraulic equipment until it bites into load-bearing soil. Because it’s screwed in rather than pushed down by the structure’s weight, it can support lighter buildings that push piers can’t — and the installer can read the drive torque to confirm capacity in real time.
Why they suit some Austin jobs
Central Texas soil isn’t uniform — clay depth and bedrock vary block to block. Helical piers handle that inconsistency well, install with little vibration (good near finished interiors), and are a strong fit for pier and beam homes, porches, and additions. For heavier slab loads, a contractor may still favor pressed-concrete or steel push piers.
Cost in context
At $1,500–$3,000 per installed pier, helical piers cost more than pressed-concrete pilings — but the right pier for your soil and load is cheaper than the wrong one that fails. Pier choice should come out of the settlement-repair diagnosis and elevation survey, not a one-size sales pitch. See the cost guide for how pier count drives the total.
Frequently asked questions
When are helical piers the right choice?
They shine where soil is inconsistent, where loads are lighter (porches, additions, pier and beam homes), and where you want immediate load transfer with minimal vibration. Installers can read the torque as they drive them, which confirms they've reached capacity.
Helical piers vs. pressed concrete or steel push piers?
Pressed-concrete pilings are the cost-effective default for typical slab loads. Steel push piers drive deep for heavy loads. Helical piers screw in (rather than being pushed by the home's weight), so they work even on lighter structures and give measurable installation feedback.
How much do helical piers cost in Austin?
Roughly $1,500–$3,000 per installed pier, more than pressed-concrete pilings but with advantages in the right soil. As with any repair, total cost depends on how many piers your home needs.
