"Workers not sure about techniques to make 90 degree turns. Used hammer chisels instead of concrete saw for cuts. Made uneven appearance in existing driveway concrete. It will blend over time. Still waiting for City Inspection which is not Company's fault."

"They didn't end up doing the work. They were really high on what they wanted to do. Other people who looked at the porch said that it was not causing an issue with any water intrusion and that there doesn't seem to be any signs on the posts that this could have been recent, it could have been long ago. So no work was done. It was a front porch that had just the level concrete on one side was dipping just a little bit. I think they were going to pump it up from underneath or something like that to level it out. I would say that their response time and their professionalism of getting the quote to us on a timely manner was good. The quote was high and yet the work was not necessary according to other quotes. They should be honest to say when repairs are necessary and when they are not. The guy who showed up was nice and professional and was on time. There was a decent response time."

"Work done involved removing an old asphalt driveway that was cracked and bulging upwards from large tree roots, removing these tree roots, and installing a new concrete replacement driveway. Owner and contractor, Ezequiel Tejeda, provided a written contract and a very reasonable charge for these services. Despite several unforseen and some personal setbacks (truck breakdown, a LOT MORE TREE ROOTS than expected, flat tire, concrete supplier arriving 3 hrs. late), Mr. Tejeda kept the work moving forward to ensure that the buyer would have a driveway completely installed by the verbally agreed upon completion timeline. Mr. Tejeda, his righthand man, Rene, were true professional craftsmen who obviously took pride in providing the client with a top quality finished product that met or exceeded expectations. Mr. Tejeda explained each step of the process as work progressed, the products being used, and why those products had been chosen. The client's approval was sought before proceeding. All workers put in extended hours each day to get the job done in a timely manner, worked hard, and kept the work area and surrounding yard and neighborhood clean and free of trash. Overall a positive experience with an honest, reliable, hardworking contractor and a crew of top quality professional craftsmen. Would hire again. Recommended to others."

Concrete Mudjacking questions, answered by experts

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

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.

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.

There is no real alternative to underpinning, although mudjacking and polyjacking are other repair methods that can add support from underneath your foundation. Rather than placing supportive piers under your structure, these involve pumping a material under your slab to lift a sunken section back into its original position. Polyjacking, in particular, is sometimes a suitable solution for stabilization issues under slab foundations, but underpinning is often accepted as the best and most permanent solution.

Mudjacking typically takes 24 to 72 hours (one to three days) to dry and cure completely before you can resume normal use. The total drying time can vary depending on the size of the project. Because the slurry mixture contains cement, it needs to harden fully to prevent the concrete slab from shifting under added weight. You should avoid walking on the concrete or placing heavy items like furniture or vehicles on the surface until it has fully set. Your concrete contractor can provide a precise timeline. As a point of comparison, if you opt for polyjacking, the polyurethane foam can dry in minutes, but it's recommended to wait about an hour before use.
