Slab lifting and settlement correction
Tier A · 26 towns covered
Polyurethane foam lifting for driveways, garage floors, patios, and pool decks that have dropped.
This comes up often enough around here that most local contractors have a settled way of handling it.
Signs that bring this up
- A driveway or walkway section sitting lower than its neighbour
- A trip hazard that has appeared at a joint
- A garage floor sloping the wrong way
- A pool deck or patio that has dropped at one corner
What a contractor will do
Polyurethane foam is injected beneath the slab, expands, and lifts it back to level. Far less disruptive than replacement, and usable the same day.
$1,000 – $4,000 — typical range, not a quote. What your home needs can only be settled by a registered contractor who comes out and looks at it.
