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. Crack injection is commonly used across Detroit, Livonia, Dearborn, Canton, and downriver communities. Every repair comes with a written contractor warranty terms.
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. Common professional methods 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 contractor-specific warranty terms
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. Common professional methods 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 hydraulic cement and caulk can fail when they are used on a moving or actively leaking crack. Hydraulic cement is rigid, while many sealants degrade under repeated moisture and freeze-thaw movement. Professional polyurethane remains flexible, but the correct material depends on whether the crack is structural, moving, or carrying water.
