Un-level concrete should be taken care of as soon as possible. Failure to do so could result in the formation of cracks, which could let water seep into your home. Additionally, the un-level surfaces could pose as a tripping hazard to your family and to anyone who visits your home. It’s important to act fast to get these problems taken care of before the damage gets any worse.
Polyjacking VS Mudjacking
Most concrete repair companies in the area will use one of two different techniques to fix and stabilize sinking slabs – polyjacking or mudjacking (slabjacking). Polyjacking makes use of polyurethane materials to help with filling voids underneath a slab and lifting it back up into position. This material is able to provide the necessary support required to keep the slab in place and keep it stable. The technique involves using a two component pump that injects the resin underneath the sinking slab.
The process for polyjacking begins with small holes being drilled into the damaged concrete surface. Next, the resin is injected into the holes. It expands and fills up all the cracks and crevices beneath the slab. After about 15 minute, the material has cured, and the slab can now be walked or driven over once again. The holes in the surface will be patched over so that they match with the surrounding concrete. This technique can be used on: driveways, patios, porches, sidewalks, pool decks, and more.
So, why choose polyjacking over mudjacking? Mudjacking makes use of a cement, mud mixture. It requires larger holes to be drilled into the damaged concrete surface, and the slurry mix isn’t anywhere near as durable or lasting as the polyurethane materials that we use. Polyjacking also requires fewer holes to be drilled into the concrete surface, and the material cures much more quickly.
Concrete Leveling & Raising
Our polyjacking services can be used to raise sinking concrete slabs at your home or business. The process is fairly quick as outlined above, and you will immediately be able to use the slab’s surface again after the foaming material has cured. As a home or business owner, it is important for you to be sure that all of the slabs on your property are level so that nobody trips on them or gets hurt. We do work on all types of surfaces, from pool decks to garage floors, and in all types of areas in between.
Slab Stabilization and Lifting
When you have sunken and un-stable concrete slabs that need to be raised, we make use of AP products, such as the AP lift 430 resin. This material is used to help with compaction, grouting, permeation grouting, stabilizing loose sand and soil underneath slabs, and it also is able to help with lifting large slabs that are sinking into the earth.
This material has many benefits over other slab stabilization techniques and materials since it cures in 15 minutes, is incredibly strong and durable, bonds with soil and concrete, and it is also classified as a closed cell material.
If your home was built on soil that is weak, soggy, or not properly compacted, it can cause your foundation to sink into the earth. When this happens, you may notice a variety of problems in and around your home, such as: windows and doors not opening or closing like they used to, cracks forming on the interior or exterior of the home, certain spots on the first floor of the home no longer feel level, or you may even actually see one or more sides of your home sinking into the earth.
Fortunately, the voids that are underneath your home causing this problem, or the weakened soil situation, can be taken care of with the AP soil series of resins. After the load bearing capacity of the soil has been properly increased through our repair and injection process, your home will be lifted back into place where it needs to be.
