Sunken Slab Repair in Ann Arbor, MI
Sunken slab repair means raising a concrete panel that has dropped below its neighbors due to soil loss or erosion underneath. Water pooling near your foundation, a garage floor that dips toward the drain, or a front stoop that has pulled away from the house — these are sunken slab problems. We fill the void beneath the slab and bring it back to grade without tearing out and replacing the concrete. That saves significant time and usually most of the cost.

How It Works
Our Process for Sunken Slab Repair
- 1
Void Assessment
We probe beneath the slab to map where soil has washed out and how large the void is before we touch anything.
- 2
Lift Port Drilling
Small holes are drilled through the slab at calculated points so we can reach the void without unnecessary damage to the surface.
- 3
Material Injection
We pump a stabilizing fill material under controlled pressure, which fills the void and gradually lifts the slab back to target grade.
- 4
Port Patching and Grade Check
Drill holes are patched flush, final elevation is verified with a level, and we confirm water will drain away from the structure.
Ann Arbor Context
Why this matters in Ann Arbor
Ann Arbor's clay-heavy soils shrink in dry summers and swell in wet springs, which gradually pulls support away from slabs. Properties near the Huron River corridor or in low-lying neighborhoods see this accelerated by seasonal drainage patterns.
Straight Talk
About pricing & scope
Scope depends on how many slabs have dropped, how deep the void runs, and whether the surrounding soil is still stable. A slab that has cracked badly during settling may need partial replacement rather than lifting.
