"We were very pleased with the job that Sam and Mike did on raising and stabilizing our pool pump house. Very professional and easy to talk with when voicing any concerns we had about the process. Having had such a good experience, we would most likely contact Adirondack Basement Systems if we have any further issues with sinking concrete. We rate them a 5+ for service and professionalism."
"The crew arrived on the planned date and worked diligently. They were knowledgeable about the issues of an old house and knew exactly what they were doing. They had to carry out the debris (concrete and dirt), and bring in the material and equipment by hand. They were careful to partition off the part of the basement where they worked and keep dust and dirt from going out of the work area. The crew did a great job in making sure the work sites were cleaned up and everything was done right. A truck had to come back 2 days later to finish up the river rock in the outside trench, as they had run out of material. The yard, considering how difficult it was to dig the trench away from the house, was in very good shape. There were tree roots ans shale that made things difficult and required a jackhammer at times. It was a difficult and messy job that they did wonderfully, inside and outside. I have been very pleased with the work and there has been no problems with water or excessive dampness in the basement."

Concrete Mudjacking questions, answered by experts
Yes, expanding foam (also known as polyurethane foam) can lift concrete. This approach, called polyjacking, involves injecting the foam rather than concrete slurry to fill voids and raise the concrete slab back into place. It’s often faster and requires smaller drill holes than traditional mudjacking, though it may come at a higher cost. Some contractors also prefer polyjacking over mudjacking for more damaged and delicate slabs.
A slurry of cement, sand, and water is injected beneath the concrete to lift and stabilize it.
On average, a mudjacking repair lasts between five and 10 years, though it can sometimes last for well beyond a decade under ideal conditions. Its longevity depends heavily on several factors, including the condition of the underlying soil, environmental conditions like freeze/thaw cycles and erosion, and whether the root cause of the sinking, such as drainage issues, is resolved. Because it doesn't always fix the underlying problem of loose soil, mudjacking is often considered a temporary solution. Proper maintenance and evaluation can help extend its lifespan.
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 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.
