Concrete Raising and Leveling

Concrete can start to sink or become uneven when the soil beneath it has started to consolidate or erode. Uneven and cracking concrete creates a tripping hazard that could become dangerous. Denver Foundation Repair & Basement Waterproofing, provides concrete raising , repair, and leveling services for any type of concrete surface.

Raising Concrete With Polyjacking

Foamjacking Before and After

Polyjacking (also known as foam jacking) is a process used for raising concrete slabs, similar to slabjacking or mudjacking, in which small holes are drilled into the concrete slab and polyurethane foam is injected underneath the slab to raise it to the proper level. This method is often faster than the traditional mudjacking methods as it uses a self-expanding and quick setting foam which spreads underneath the concrete slab, filling gaps and holes in the supporting soil, and solidifies after a short amount of time. Our team uses the polyjacking solutions from SafeBasements™ which was developed and tested to maximize the effectiveness of the foam. These products not only save you time but also money when considering other options for concrete leveling.

One question that most homeowners around Denver have about polyjacking is: How long does it last? The short answer to this is that polyjacking is a permanent solution. Because there is no dirt or a mud mixture being used to raise your concrete slab back to the correct level, there is nothing that will erode over time. The benefit of using polyjacking is that the hardened polyurethane solution is completely waterproof and erosion resistant allowing it to support your concrete slab for the rest of its lifetime. However, If the soil conditions underneath the slab continue to deteriorate you may again see sinking underneath your slab. This is the case with almost any concrete lifting method on the market. Unlike other solutions, however, polyjacking expands and compacts the soil beneath it providing a solid footing for the polyurethane foam and allowing it to last longer.

Concrete Repair Process

Because every job is unique, we will go over the specifics of your project before we start. When repairing uneven concrete, the process typically takes a few hours to complete. We begin by cleaning off the damaged area to keep dirt or debris from getting inside during the repair. Next, we drill tiny holes into the top of the surface and inject a special polyurethane foam material through the openings. The polyurethane foam fills up the space beneath the concrete to lift it up, making the surface level once again. The holes we drilled are then filled and patched over. After the repair is done, we will provide you with an estimated time frame the surface will need to dry before you can walk or drive over the concrete.
