Concrete raising is typically about half the cost of replacing the same concrete. Ultimately, the cost of raising or stabilizing concrete is a direct reflection of how much leveling material the project will require.
After the slab has been raised, the only visible evidence that the concrete has been repaired are the holes. For this reason, polyurethane has gained HUGE popularity because of the nearly invisible 3/8″ or 5/8″ holes that remain after the job is completed. Polyurethane concrete raising process also requires considerably fewer holes than traditional mudjacking.
Foamjection foams are environmentally friendly, consisting of 39-49% renewable and recycled materials. Foamjection foam leaves the smallest carbon footprint of any of the foams in the industry.
A polyurethane hose is ran straight from the truck/trailer to the repair site without driving a single piece of equipment on your lawn.
The hole is patched over with cement. The concrete is ready for use immediately. However, it is recommended to allow the patch material to set-up before use, typically a couple of hours.
Both methods of concrete lifting will achieve the same results. Mudjacking concrete leveling and polyurethane concrete raising will raise and support sunken or unstable concrete slabs by drilling holes and pumping material under the slab.
Settled concrete is commonly a result of poor soil conditions beneath a slab. Polyurethane has become a popular repair method because the injection holes are much smaller and the material is so lightweight compared to traditional mudjacking material, it will not further burden the already weak soil. Mudjacking uses a sand based material that is infused with Portland cement. This slurry is hydraulically pumped under the slab to fill voids and raise the concrete. Mudjacking material weighs on average 100 lbs per cubic foot.
Polyurethane Concrete Raising uses a foam material that is injected under the slab. When the components of this material are mixed, a reaction causes the material to expand. This expanded foam fills any voids beneath the slab and raises concrete. This material will never lose density, is permanent and weighs only about 2 lbs. per cubic foot.
