At Acme Concrete Raising & Repair we only use polyurethane foam injection to level and raise concrete throughout the Chicago area. We specialize in the concrete foam jacking method because it is proven to be faster, cleaner, cheaper and longer-lasting.
Although concrete raising results between polyurethane foam injections and old “mudjacking” methods may appear similar, there are significant differences between polyurethane and mudjacking methods. From the repair process to the materials and equipment used, foam jacking proves to be a far superior and sustainable repair method in the long term.
If you have an uneven sidewalk, driveway, or patio, contact the experts at Acme Concrete today for a foam injection quote. We’ll get your concrete slab repaired and level in no time at all!
As Chicagoland’s first contractor to focus specifically on raising sunken concrete with polyurethane foam, we developed the Smart Lift System to provide our customers with the Ultimate Solution for Settled Concrete! The simple yet advanced foam injection technology allows Acme Concrete to raise sunken concrete with a three-step process:
Small ⅝ inch diameter holes are strategically drilled through the sunken concrete and temporary injection ports are installed.
Next, specially formulated polyurethane is injected through the injection ports to raise the concrete back to its original position.
The injection ports are removed and the holes are patched. Since the polyurethane cures in about 15-minutes, the raised concrete is ready for immediate use.
Check out the video above to see just how quick and simple it is to level a sidewalk with our superior polyurethane foam concrete lifting equipment.
Our professional concrete lifting and leveling services are simple yet effective. Research shows our state-of-the-art foam jacking equipment provides customers the highest quality results possible. Even better is our commitment to Health, Saftey & the Environment! See below to learn more about our process of revitalizing sunken concrete and how Acme’s modern, quick and efficient poly foam injection method outperforms mudjacking.
|Acme Concrete Raising & Repair: Polyurethane Injection||Typical Mudjacking|
Modern Poly Foam Equipment UsedPolyurethane foam concrete lifting projects typically require a small box truck or pickup truck & small trailer. The required poly foam equipment and materials are located in this single vehicle – no heavy construction trucks or equipment are needed. Our concrete lifting foams are centrally located and ready to use on demand. There is no manual mixing required, saving labor and time.
Most mudjackers use heavy duty construction vehicles. Dump trucks may also be used in mudjacking.
Small Holes for Less Invasive Concrete LiftingTo begin, we create a few small holes (about the size of a dime) in the concrete allowing us to inject the polyurethane foam lifting material. Once the holes are placed in strategic locations, special injection ports are installed creating a secure, sealed connection between our lifting equipment and the concrete. This unique feature prevents the poly foam 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 causing a messy work area and require cleaning.
Polyurethane Slab Lifting ProcessWe then connect advanced, computer-controlled equipment to the injection ports and inject a two-part polymer. The materials travel laterally beneath the concrete, reacting and expanding to permanently fill voids while simultaneously raising and leveling the sunken concrete. The polyurethane slab lifting process is quite simple.
Depending on the contractor, mudjackers pump various wet mixtures below the concrete. (every mudjacker uses their own "recipe") Slabs are sometimes “over-raised” to account for future shrinkage.
Clean & Fast Equipment RemovalFollowing the lifting process, injection ports are removed, leaving a clean repair and neatly maintained work area. Since the bulk of our poly foam injection equipment is remote and self-contained, equipment removal is as simple as rolling up a hose. And 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 clogs up their equipment.
Ready to Use Quickly After InjectionThe poly foam jacking 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.
