Slab Foundation Repair in Oklahoma City, OK
Slab foundation repair in Oklahoma City addresses the most common foundation type in the metro — the concrete slab-on-grade poured directly on our shifting clay soil. At OKC Foundation Pros, we lift, level, and stabilize slabs that have settled, heaved, or cracked as the ground beneath them swells and shrinks. If you’re seeing cracks running across the floor, doors that won’t close square, gaps opening between walls and trim, or one room sitting visibly lower than another, we’ll find out why the slab moved and bring it back to level for good.
Why Oklahoma City Slabs Crack and Settle
Most homes across the OKC metro sit on a concrete slab, and that slab is only as stable as the clay underneath it. Our red clay swells when it’s wet and shrinks in drought, so a slab poured on it is constantly being lifted in one spot and dropped in another — the differential movement is exactly what cracks concrete and racks the walls above. Heavy spring storms, long summer droughts, poor drainage, and slow plumbing leaks under the slab all make it worse. Left alone, a small settlement crack widens every wet-dry season. Our repairs follow the structural standards published by the Foundation Performance Association, so the slab is stabilized at the cause, not just patched at the surface.
Our Slab Foundation Repair Process
- Inspection and elevation survey. We measure floor elevations across the slab, map every crack, and check doors, trim, and plumbing to find where and why the concrete has moved.
- Diagnosis and plan. You get a written scope and firm price — whether that’s polyurethane lifting, piering, or both — with no vague “call for a quote.”
- Lift and stabilize. For most settlement we inject high-density polyurethane foam through small ports to raise and re-level the slab; for deeper movement we install concrete or steel piers to reach stable soil. Where a bowing wall is also involved we handle it alongside with bowing wall repair.
- Verification and warranty. We re-measure to confirm the slab is level and stable, seal the injection ports, and hand over a written, transferable warranty.
Slab Foundation Repair Costs in Oklahoma City
Cost depends on how far the slab has moved and which method the repair calls for. Typical OKC ranges:
- Crack sealing and minor leveling: $600–$2,000
- Polyurethane foam lifting (polyjacking): $1,500–$6,000
- Concrete or steel piers: $1,200–$3,000 per pier
- Whole-slab stabilization: $5,000–$15,000+
Acting early almost always costs less, because a slab that’s caught after minor settlement needs far less lifting and fewer piers than one left to drop for years. If the movement is part of a wider structural problem, it’s worth reviewing full foundation repair in the same visit.
Frequently Asked Questions
How do I know if my slab foundation needs repair?
Watch for cracks running across the floor, sloping or uneven floors, doors and windows that stick or won’t latch square, gaps between walls and trim, and cracks in drywall above doorways. Two or more of these together usually means the slab is moving.
What is polyurethane foam lifting?
We drill small ports in the slab and inject an expanding high-density foam underneath. The foam fills voids and raises the concrete back to level. It cures in minutes, the ports are tiny, and you can use the space almost immediately — it’s faster and cleaner than older mudjacking.
Can a leaking pipe under the slab cause damage?
Yes. A slow plumbing leak saturates the clay in one area and causes localized heave or settlement. We check for plumbing-related moisture during the inspection so the repair addresses the real cause.
Do you offer free estimates and a warranty?
Yes. Every inspection and written estimate is free, and our slab repairs come with a transferable warranty that stays with the home if you sell.
Slab Foundation Repair Service Areas
We repair slab foundations across the Oklahoma City metro, including Norman, Edmond, Moore, Midwest City, Yukon, and Mustang.
A settling slab doesn’t stabilize on its own — every wet-dry season widens the cracks and pulls the structure further out of square. OKC Foundation Pros will inspect it free, tell you straight whether it needs action, and bring the slab back to level with work backed in writing. Call now to lock in your free estimate.
