"Liffel Concrete provides excellent service. Job strategy was clearly communicated before the work was bid and the bid clearly listed all work. All items were completed on time and pricing was competitive. The finished product is excellent, more like what you might see in a grocery store than in a shop. The floor is very flat with a nice, smooth troweled finish. I recommend Liffel Concrete."

Concrete Mudjacking FAQs, answered by experts

Most states and municipalities don’t require concrete mudjacking companies to carry a specific license, but they usually need to have a general contractor’s license, and they should be fully insured. The only exception is if the mudjacking company provides foundation repairs as well, or if it offers mudjacking for home foundations. In that case, they will typically need a foundation repair contractor’s license. You can check state requirements and then use Angi’s license lookup tool to confirm that a company is properly licensed to provide mudjacking services in your area.

Mudjacking restores level surfaces, prevents further damage, and is more cost-effective than a full replacement.

Pros often use mudjacking or polyurethane foam injection to level a sunken concrete patio. Both methods lift the slab by filling voids beneath it. After properly compacting the soil beneath it to prevent future settling, the concrete may need to be removed and re-poured for severe sinking.

Many contractors offer warranties for their work. Confirm terms before starting the project.

Generally speaking, push piers—or steel piers—are the best option for underpinning, as they reach down to solid bedrock to find support for your foundation rather than relying on soil, which could be subject to the same issues as the soil directly below your foundation. However, the best underpinning method for your home depends on your location, how far down the bedrock is, and the type of soil in your area. Helical piers are usually the best option for sandy soil or in areas where the bedrock is too deep to use steel piers.
