One of the first clues that a slab is shifting shows up inside the house. Maybe the floor feels off when you walk across it, or a door that used to swing fine now sticks in the frame. These changes usually mean the concrete isn’t sitting on solid ground anymore, and slab foundation repair may be needed to keep the structure stable.
The fix depends on the cause. Small voids under the slab can often be filled, while bigger problems call for steel piers to carry the weight. Knowing which method fits your situation helps you plan the right repair.
What Are the Most Common Slab Foundation Issues?
The most common signs of slab problems include:
- Slanted floors or walls
- Cracks in the drywall or ceiling
- Doors or windows that stick
- Gaps around baseboards or between walls and ceilings
All of these signs point to one of two major problems: either there’s a void under the slab, or the foundation has settled or cracked. Let’s look at how we fix both.
How Do We Repair Voids or Depressions?
If your slab has low spots or dips, it’s likely due to empty space under the concrete. We call these voids. At KC Pier, our top fix for this issue is polyjacking.
Polyjacking involves injecting a high-density polyurethane foam beneath the slab. The foam expands and lifts the concrete, filling the space and leveling the surface.
Benefits of Polyjacking:
- Fast and clean process
- Minimal disruption
- Long-lasting results
- Eco-friendly material
Key Takeaway: If your slab has dropped in places but isn’t cracked, polyjacking may be all you need to level and stabilize it.

What If My Slab is Cracked or Settled?
When the slab itself has cracked or dropped due to soil movement, we take a different approach. In these cases, we install concentrically loaded piers, strong steel supports driven deep into the ground until they reach stable soil.
These piers lift and hold the structure in place. We space them according to engineering guidelines and back them with a lifetime warranty.
Why Choose Concentric Piers?
- Works for serious settling
- Holds heavy loads
- Permanent solution
- Includes engineering-based layout
How Much Does Slab Foundation Repair Cost?
Each home or building is different. That’s why we start with a free consultation to assess the damage and recommend the right repair.
Costs depend on:
- Size and location of the issue
- Type of repair (polyjacking vs. piers)
- Number of piers needed
- Accessibility of the work area
Pro Tip: Fixing a problem early can save thousands. Small voids cost far less to fix than widespread settling.
