Concrete Raising / Polyurethane Concrete Raising

Concrete Raising with Acme Concrete Raising & Repair
At Acme Concrete Raising & Repair we only use polyurethane foam injection.  This specialized process has been used to lift sunken concrete for over 20 years. Previously, the use of polyurethane foam injection was mostly limited to Department of Transportation projects involving roads and bridges due to US Patent protection that was in effect until 2003. Since then, the use of polyurethane has been gaining popularity for repairing settled concrete in both residential and commercial applications. It is now the modern method.

Although repair results between polyurethane injections and old “mudjacking” methods may appear similar, there are significant differences. These differences include: repair procedures, concrete raising materials, equipment, and most importantly, short & long-term reliability of completed work.

Acme Concrete Raising & Repair lifts concrete with advanced technology enabling us to perform high-quality, quick, clean repairs that are more cost effective for the long term.

What to Expect When We Lift Concrete With Polyurethane

Our concrete lifting and leveling services are simple yet effective. Research shows our state-of-the-art equipment provides customers the highest quality results possible. Read on to learn more about our process, and enjoy some examples of how Acme’s modern system outperforms mudjacking.

This is how we make revitalizing your sunken concrete quick and efficient:

Acme Concrete Raising & Repair: Polyurethane InjectionTypical Mudjacking
The typical residential project requires a pickup truck and small trailer. The necessary equipment and materials required are located in this single trailer – no heavy construction vehicles are needed. Our concrete lifting foams are located within this enclosed trailer and are ready to use on demand. There is NO manual mixing required. (This saves labor time, saving money.)Most mudjackers use heavy duty construction vehicles. Dump trucks may also be used in mudjacking.
To begin, we create a few small holes in the concrete allowing us to inject the lifting material. Don’t worry, they are small, ⅝” holes, about the size of a dime. Once the holes are placed in strategic locations, special injection ports are installed. The injection ports create a secure, sealed connection between our equipment and the concrete. This unique feature prevents lifting material from leaking or spilling during the concrete raising process. The overall benefit of injection ports is a cleaner, more effective raise.Mudjacking will typically require much larger holes – ranging anywhere from 1” to 2” in diameter. Most mudjackers do not use injection ports. Material spills and leaks can occur and require cleaning.
We then connect advanced, computer controlled equipment to the injection ports and inject a two-part polymer through them. The materials travel laterally beneath the concrete, chemically reacting and expanding to permanently fill all voids while simultaneously raising and leveling the sunken slab.Depending on the contractor, mudjackers pump various wet mixtures below the concrete. Slabs are sometimes “over-raised” to account for future shrinkage.
Following the lifting process, injection ports are removed, leaving a clean repair and neatly maintained work area. Since the bulk of our equipment is trailer mounted and self contained, equipment removal is as simple as rolling up a hose. Also, due to the nature of our clean repair technology, cleaning of equipment or the work itself is extremely minimal.Since the mudjacking repair process can be a bit sloppy at times, mudjackers typically need to wash down the repaired surfaces before material dries. They may also need to wash mud mixers and pumps before material dries and hardens in their equipment.
The material we use to lift and level concrete is fully cured in about 15-minutes after injection. It doesn’t matter what type of structure we raise; a sidewalk, garage floor, driveway, parking lot, etc. When the job is complete, the concrete is free to use without restriction.Some mudjacking slurries can require 24 to 48 hours to fully cure. Normal use of the concrete may need to be avoided for days following a repair.
