"We chose American Waterworks to complete the PolyLevel process on our concrete Gazebo floor. The floor had subdivided into multiple sections and heights. We appreciate American Waterworks' professionalism and workmanship!!"
"Our project was to lift and balance a garage floor and long driveway using foam. Marc, Ben and Andrew showed up on time, did a thorough job, explaining the process every inch of the way. They did what was contracted for plus a bit. The cleanup was everything I could have asked for. We were told exactly what possible problems to watch for and what to do about them. A very good experience and a good warranty."
"The estimate was in our budget range and included a narrow sidewalk to our back fence gate. Total square footage was just under 500 square feet which made a nice front patio area. The workmanship was top notch and we have had many compliments from neighbors and friends."
Concrete Mudjacking questions, answered by experts
Polyjacking can be a permanent solution to sunken concrete if you also address the underlying issue—like poor drainage—at the same time. The polyurethane material itself can last as long as or even outlast the concrete you’re lifting it with. Your sunken concrete issue will likely return if you don’t couple polyjacking with proper drainage to prevent future soil movement and sinking.
A slurry of cement, sand, and water is injected beneath the concrete to lift and stabilize it.
Charges correlate with surface size, settlement depth, and access, often yielding significant savings over concrete replacement.
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.
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.
