"They were wonderful! The best price of the 4 contractors we contacted. The only contractor that understood our desire to reuse the existing bricks. They arrived promptly, worked hard all day and left the area as clean as they found it. I highly recommend this company and would hire them again in a minute!"

Concrete Leveling questions, answered by experts

A good slump height really depends on the project, but there is a use for nearly all slump levels. For example, low slumps are best in projects that require structure, such as curbs and roads. High slumps often require additional reinforcement, but they flow more freely into hard-to-reach spaces.

Address drainage issues, avoid heavy loads, and seal cracks to prevent future settling.

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.

Mudjacking typically takes 24 to 72 hours (one to three days) to dry and cure completely before you can resume normal use. The exact time can vary depending on the size of the project. Because the slurry mixture contains cement, it must fully harden to ensure that added weight from walking, furniture, or vehicles won't shift the concrete slab. A professional contractor can advise you on when the surface is safe to use. For comparison, if you use polyjacking instead, the polyurethane foam can dry in just a few minutes, but it's best to wait about an hour before use.

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