Concrete Slab and Void Repair in Spokane, WA
Slabs on grade can crack or sink when soil under them washes out or compacts. Contractors may fill voids under the slab with grout or polyurethane foam, or stabilize the slab with piers.
Questions to ask
- Note where the slab is sinking and whether it is near a downspout.
- Ask what material will be injected and how holes are patched.
- Ask what is done about the water source.
Foundation repair cost depends heavily on the method and how many piers or how much wall is involved. The only reliable number is a written estimate after an on-site inspection, so we do not publish prices.
