Arizona Repair Masons is the leading contractor for underpinning in the State of Arizona for several years now; and have helped thousands stabilize and raise their sunken foundations. However, there are times when there are structures that needs to be stabilized and or lifted and helical piers are not a viable option because the structure is not capable of the point stresses that are involved with piering. By driving an injection pipe deep below the surface and then pumping various types of grout, the soil itself can be stabilized and even be made stiffer and denser.
Or are you preplexed about sink holes and unstable soils. Arizona Repair Masons has been performing this technique for years now. The process is similar in practice to slabjacking, however instead of grouting only under the slab or filling the hole we drive the tube to a predetermined depth, and pressure grout the weak soils making them more stable. This also can be beneficial to fill voids in very rocky soils that traditional piering may not be suitable for.
In order for this type of repair to be effective deep soil testing must be done by a competent soils testing engineer. An effective grouting plan can then be designed that will take into effect the various layers of soil and their densities to avoid injecting on top of loose soil and exacerbating the problem by adding weight on top of the incompetent soil.
We have successfully grouted pavements, building slabs, bridge approach slabs, house floors, pools and other simliar types of infrastructure. Our crew is talanted, hard working, and careful. As you run into soil problems of any type, please call and challenge us to bring you the right soultion to each problem.
