Concrete Lifting

Polyurethane foam concrete raising material is injected as a liquid that sets-up as a rigid foam. This foam will NEVER loose density or shrink. This material is lighter than traditional mudjacking material, and requires less holes to install. Even better, the holes are smaller creating a virtually invisible repair!

Mudjacking material is a sand based grout that will not lose its density. Combined with Portland cement this non-organic mixture is pumped under the slab of concrete. Different from organic material, RaiseRite’s slurry will not decompose or breakdown.

The RaiseRite trucks remain parked on the street, while the concrete repair crew maneuvers the equipment to the site requiring repair. The hydraulic mudpump is roughly the size of a riding lawn mower. Armed with many lengths of hose, the mudjacking crew can reach just about anywhere. If you are using polyurethane to repair your concrete, a hose is ran straight from the truck/trailer to the repair site without driving a single piece of equipment on your lawn.

After the concrete is raised with mudjacking material, a foam plug is inserted into the hole, and 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. Foam plugs help RaiseRite patch the holes, and act as a shock absorber, when slabs are affected by the frost cycle.  Holes that are not patched with foam can pop out, when the material and earth under the slab expand from freezing. When concrete is raised with polyurethane foam (FoamJacking), these plugs are not used. The material used for raising the slab replaces the inserted foam plug as a shock absorber.

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.
