Polyurethane concrete raising achieves the same results as traditional mudjacking, but with a lightweight material that requires smaller and fewer injection holes. Also known as foam lifting or poly lifting, polyurethane concrete lifting is the latest and greatest concrete repair method available.

Firstly, we believe it’s good for you to know that most concrete raising jobs will take between one to two (1-2) hours—start to finish—and your concrete will be ready for use immediately upon completion!
1. When you level your uneven concrete using poly foam concrete raising techniques, ⅝” injection holes (Size of a dime!) are strategically drilled around the areas where the concrete is sunken and requires lifting.
2. The concrete raising equipment is contained in a truck or trailer, and has a sufficient length of hose to accommodate most locations, the hose is extended to reach the area in need of repair
3. Once everything is prepped and the hose and materials are in place, the polyurethane foam is injected through the holes which fills the space underneath the concrete slab, using the concrete slab itself to drive the foam into the crevices, thereby lifting the concrete back to its original, correct level.
4. Upon completion of leveling the concrete, the injection hole(s) are filled discretely with new cement, allowing you to use your surface immediately.

While mudjacking usually lasts 2-5 years, polyurethane can last much longer if properly maintained. Check here for more information on polyurethane vs. mudjacking repairs.

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. In general terms, concrete raising can cost between $2-$5 per square foot.

For example: a 10 ft. x 10 ft. section, that needs to be raised, figures to 100 square feet. This job would cost somewhere between $200 and $500 to repair. How far the slab is settled, if there are voids present, or if other sections need to be involved in the repair, will determine where in that scale the job would cost.

When our work is completed, it will be your responsibility to caulk the seams of the sections that were repaired, or backfill against any exposed areas to contain the material, and prevent future sinking.

Self-leveling cement caulk can be purchased easily at a home improvement store and works great for sealing joints. Using a silicone based, self-leveling caulk, is recommended. If a crack is very large, to use less material, sand can be used first between the crack, before applying the caulk on top.

Preventing water from going under the slab is key to preserving the repaired slab. Make sure that your downspouts are correctly placed, to assure water runs away from your concrete slabs or foundation.

Taking these suggested steps for preserving your raised concrete is a condition of your RaiseRite warranty.

Solid slabs of concrete can be raise and stabilized. Gravel areas or blacktop are unable to be repaired, and need to be replaced or re-installed to remedy settling issues. Slabs of concrete that are badly cracked may also be too damaged to lift.
