"My first contact with Mount Valley Foundations was with Carlton Cisson. He was prompt, professional and provided details of what needed to be done with a drawing explaining all and a quote right on the spot. Every time I reached out to Carton after that first meeting regarding the task at hand, scheduling the work or just to answer questions...Carlton responded quickly. For anyone that might possibly be needing foundation work of any kind, I highly recommend Carlton Cission as the first point of contact. Shaun Dixon, Alex Hernandez, Milton Martin and Dre Nesbitt were the team assigned to replacing the entire foundation of the wedding venue restroom I hired Mount Valley for (from the interior floor to the dirt on the ground beneath...literally). 100% rotten through by years of undetected moisture from inadequate airflow and dehumidification. Shaun (the forman) was in constant communication with me throughout the entire process of rebuilding. He didn't just explain in words, he took time to visually point out the areas this construction would be addressing and what I should expect. Shaun was clear and concise in describing what was being done and answering all of my questions (which was many). The entire process, including the work ethic of this 4-man team, was conducted in a very professional manner. A grusome task, while keeping a friendly, personable demeanor throughout. Hoping I never have to have such foundation work ever done again, but will certainly call Mount Valley again, if I do!"

"Jeremy and Austin were pleasant, engaging, hardworking, and competent workers for HydroHelp911. They arrived on Monday and started working immediately. They had to remove wet insulation, rotted floor joists, and replace piers and add jacks. They showed me pictures of their work in progress and asked me if I had questions and explained the answers clearly. They installed a French Drain and added a vapor barrier. Even though the time allotted to complete all their jobs was 10 days, they completed everything in 6 days and cleaned up everything from my yard. I would recommend this company for the thoroughness of work done and for the early completion of the job."

Concrete Leveling FAQs, answered by experts

Most houses are expected to settle over time, but foundation sinking of more than a few inches or uneven sinking of more than an inch for every 20 feet is cause for concern. Any significant or uneven sinking should be assessed by a professional to determine the cause and perform any necessary repairs. 

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.

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.

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.
