| Method | Cost | How It Works | Best For |
|---|---|---|---|
| Steel push piers | $1,000-$3,000 per pier | Driven down using the home's weight | Heavy structures, deep stable soil |
| Helical piers | $1,500-$3,500 per pier | Screwed into the ground like a large auger | Lighter structures, porches, new additions |
| Mudjacking | $3-$6 per sq ft | Cement slurry pumped under slab | Driveways, patios, walkways |
| Polyurethane foam | $5-$25 per sq ft | Expanding foam lifts the slab | Interior slabs, fast cure, smaller holes |
When Piers Make Sense
If the soil under your home is compressing or shifting, piers are the long-term fix because they bypass that soil entirely. Most homes need 6-12 piers, which puts full projects at roughly $5,000-$25,000.
When Slabjacking Makes Sense
For a sunken garage floor, patio or sidewalk, lifting the slab is far cheaper than replacing it. Foam costs more than mudjacking but adds less weight and cures in hours.

Neither is better in every case. Steel push piers suit heavier homes; helical piers suit lighter loads and places where the structure is too light to drive piers.
It can last many years if the cause, usually drainage, is fixed. If water keeps washing out the soil, the slab can sink again.
