Sinking slab lift

Sample Contractor Quote

Drill injection ports and lift sunken slab area with polyurethane foam. Approx. 220 sq ft. Total: $4,600.

Price Assessment

$4,600 can be reasonable for a defined slab lift, but the quote should explain why the slab sank and how re-settlement is handled.

Possible Red Flags

  • No foam density
  • No cause of voids
  • No drainage correction

Missing Items to Confirm

  • Lift tolerance
  • Foam specification
  • Warranty length
  • Crack repair after lift

Questions to Ask

  • What caused the void?
  • How much lift is expected?
  • What if the slab settles again?
