Why use Contractors for Concrete?

Contractors for Concrete helps you describe the settlement before requesting a repair contractor match. The questions below help you compare the intended result, repair limits, and what happens if lifting is unsuccessful. You can start without choosing a slab-lifting method.

Example brief

Assess a settled walkway panel

Work to discuss
Water collects beside the low panel. Ask about the cause and repair options before choosing a method.
Size and timing
Not sure yet. Confirm during the project discussion.

Questions to take to a contractor

  • What caused the loss of support, and is movement continuing?
  • What finished height, connections to nearby surfaces, and drainage result will the contractor aim for?
  • What material, injection holes, monitoring, and joint or hole repairs are included?

Illustrative request, not a completed project or quote. Your answers replace this example; a contractor confirms the work and price.

What sunken concrete repair projects can you request?

You can request an assessment of a sunken driveway, uneven walkway, settled patio, or slab that may need lifting or replacement.

Movement affecting foundation walls, columns, framing, occupied interiors, or utilities needs an appropriate structural or specialist evaluation. Describe these conditions explicitly rather than treating them as ordinary outdoor slab leveling.

What should you include in your sunken concrete repair request?

Include the affected panels, visible damage, changes over time, water concerns, and previous repairs in your sunken concrete repair request.

  • Identify affected panels and nearby doors, steps, walls, or drains.
  • Describe the low areas, visible cracks, and any changes over time.
  • Note standing water, washout, or suspected leaks without guessing the cause.
  • Include photographs and any prior repair information in your request.

What should you ask before choosing a contractor?

Before choosing a sunken concrete repair contractor, ask what work the price includes, how the project will be handled and what remains your responsibility. Use the same questions for each proposal, and confirm experience, licensing where required, insurance and references.

How might a contractor repair sunken concrete?

A contractor may evaluate lifting, stabilization, or replacement for sunken concrete, depending on the remaining slab and the cause of lost support. Raising a slab alone does not resolve continuing erosion or water movement.

Lifting an intact slab
Cement-based grout or expanding polyurethane foam can be injected beneath a slab to raise it. Ask how the intended finished height and drainage will be monitored.
Stabilizing a void
Filling a void beneath concrete can restore support without deliberately raising the surface. Confirm whether the quote promises support, a change in elevation, or both.
Replacing damaged concrete
Severely cracked or deteriorated panels may need replacement. Ask whether excavation and correction of the base are part of the proposal.
Investigating continued movement
Poorly compacted fill, soil changes, erosion, and leaks can contribute to settlement. Ask what cause is established, suspected, or outside the contractor's assessment.
What happens during professional slab lifting?

Professional slab lifting involves assessing the panels, defining the intended finished height, introducing material beneath the concrete, monitoring movement, and reviewing the finished transitions.

  1. Inspect the panels and investigate suspected support loss.
  2. Establish intended finished heights and drainage.
  3. Plan and drill injection holes.
  4. Introduce material gradually while monitoring the slab and adjacent surfaces.
  5. Close holes and review joints, edges, and door-entry levels.

Hole pattern, material, and achievable result depend on the project. General technical context: ACI RAP 11: Slabjacking and FHWA guidance on slab stabilization. The FHWA document concerns pavement preservation, not residential project specifications.

How does contractor matching work?

Contractors for Concrete checks your project type and ZIP code against the specialties and service areas contractors have submitted. Requests are assigned to one contractor at a time, subject to availability. We help with matching; we do not perform the concrete work.

  1. 01

    Describe your project

    Provide the work, location, timing, and contact details in the request form.

  2. 02

    Check matching availability

    Your submission result shows whether a potential match was found or the request needs further attention. An unmatched request is not a confirmed appointment.

  3. 03

    Discuss and decide

    Confirm that the contractor handles your specific work, review their proposal, and decide whether to hire.

Does sunken concrete always need replacement?

Sunken concrete does not always need replacement. An intact slab may be a candidate for lifting, while severe deterioration or support problems may require a different scope. Ask the contractor to explain why the proposed method fits the condition.

Is concrete leveling the same service as sunken concrete repair?

Concrete leveling is one possible part of sunken concrete repair. A repair may also involve addressing lost support, water movement, or replacing damaged panels, so the request should describe the problem rather than prescribe only a lift.

What can help you prepare before hiring?

The slab-lifting comparison, repair-versus-replacement guide, and repair cost guide can help you discuss repair options and budget with a contractor.
