Wayne County's #1 Foundation Crack Repair Experts
Foundation cracks in Wayne County homes almost always come from one of three causes: hydrostatic pressure from saturated clay soil, freeze-thaw cycle expansion, or differential settlement on graded fill. We've sealed thousands of cracks across Detroit, Livonia, Dearborn, Canton, and downriver. Every repair comes with a transferable lifetime warranty.
Polyurethane Injection — $400 to $700 per crack
The right choice for active leaks. Polyurethane foam expands inside the crack, fills every void, and stays flexible — so it moves with the wall instead of cracking out. Most jobs take 1–2 hours. We use this method on roughly 70% of Wayne County cracks.
- Expands 8x to fill micro-voids
- Stays flexible — survives freeze-thaw cycles
- Cures in 30 minutes — basement usable same day
- Backed by lifetime warranty
Epoxy Injection — $500 to $900 per crack
For non-moving structural cracks. Epoxy is rigid and structurally bonds the two sides of the wall back together. We use this on settled-but-stable foundations, garage floors, and post-tension slabs.
Crack Types & What They Mean
- Vertical hairline — concrete shrinkage. Cosmetic. Seal to stop water.
- Diagonal — minor settlement. Monitor if hairline, seal if >1/8".
- Horizontal — STRUCTURAL. Wall is failing under hydrostatic pressure. Needs reinforcement (see bowed wall repair), not just sealing.
- Stair-step in block — differential settlement. Needs underpinning.
Why DIY Crack Sealers Fail
Hardware store crack sealer is hydraulic cement or caulk. Both fail within 18 months in a Wayne County basement. Why? Hydraulic cement is rigid — when the wall moves (and Michigan walls move), it cracks out. Caulk degrades from constant moisture. Professional polyurethane stays flexible AND waterproof for the life of the home.
