Cracked or sunken slab? Get emergency slab repair

A slab that suddenly cracks, sinks, or heaves is not something most homeowners can wait weeks on. It can signal water pooling under a foundation, erosion under a driveway, or a plumbing leak moving soil beneath the concrete. This page is for finding a contractor who responds quickly to that kind of problem, not for browsing general repair options at a slower pace.

Expect the contractor to check for the underlying cause (drainage, tree roots, plumbing, soil settlement) before quoting a fix. Fast response does not mean a rushed patch job: a good crew will still explain whether the fix is mudjacking, polyurethane foam injection, slab replacement, or a partial pour.

  • Same-day or next-day site visits for active hazards (trip risk, water intrusion, structural concern)
  • Temporary safety measures if a full repair has to wait on permits or weather
  • Written explanation of why the slab moved, not just a patch quote

What it costs

Emergency slab work costs more than scheduled repair because of rush scheduling and diagnostic time. The real cost driver is the size of the affected area and whether the fix is surface-level (patching, sealing) or requires lifting/leveling equipment like mudjacking or foam injection. A contractor who has to excavate or address a drainage problem underneath will price higher than one doing a cosmetic patch.

FAQ

How fast can a contractor get to a sunken slab?
Many of the emergency-oriented contractors in this area offer same-day or next-day visits for active hazards like trip points or water pooling, though exact timing depends on their current schedule and the severity you describe.
Is a sunken slab always a foundation problem?
Not always. It can be soil settlement, erosion, a broken drain pipe, or root damage under the slab. A contractor should identify the cause before recommending mudjacking, foam injection, or replacement.
Can a cracked slab be temporarily made safe until full repair?
Yes, many crews will flag trip hazards, cover exposed rebar, or apply a temporary patch if the full repair needs to be scheduled out or wait on weather.
