Slab piers provide a specialized solution for stabilizing and lifting concrete slab foundations that have settled or cracked due to weak soil.
What Are Slab Piers?
Slab piers are steel foundation support systems designed specifically for homes or buildings with slab-on-grade foundations. Unlike traditional piers that attach to footing structures, slab piers are driven through small holes in the slab itself to reach stable soil beneath. Once installed, they transfer the weight of the slab to deeper, more reliable ground.
When Are Slab Piers Used?
Slab piers are used when a concrete floor slab is settling unevenly or cracking due to:
- Soil erosion or compaction beneath the slab
- Expansive clay soil that shifts with moisture changes
- Poor site preparation or improper grading
- Hydrostatic pressure or plumbing leaks below the slab
How Slab Piers Work
- Small holes are cored through the interior slab in affected areas
- High-strength steel piers are hydraulically driven through the holes to load-bearing soil
- Adjustable brackets connect the pier to the underside of the slab
- The slab is gently lifted and stabilized using hydraulic jacks
- Holes are patched and leveled with concrete for a seamless finish
Advantages of Slab Piers
- Non-invasive: Minimal disruption to flooring and interior finishes
- Targeted Solution: Installed only where support is needed
- Permanent Fix: Eliminates future sinking caused by unstable soil
- Clean & Fast: No large excavation or heavy demolition required
- Safe Lift: Controlled leveling minimizes damage to walls and finishes
Slab Piers vs. Other Pier Systems
Slab piers are uniquely designed for slab-on-grade foundations. Push piers and helical piers are excellent for deep footing foundations, but they require exterior access and do not work as effectively when there’s no crawl space or traditional footing. Slab piers provide direct interior support where other systems fall short.
Where Slab Piers Are Commonly Installed
- Homes with concrete slab floors (no crawl space or basement)
- Warehouses, commercial spaces, and garages
- Interior concrete floors with visible cracking or slope
- Older homes built on expansive or fill soils
