When you see a sinking concrete slab, or a cracked driveway, you might think you’re in for costly concrete replacements. However, you might have the option to repair your concrete driveway instead of completely replacing it.
There are a few different methods for concrete repairs today, so it’s important to understand your options. One option for lifting concrete slabs is known as mudjacking. This is a fairly inexpensive process where a slurry of mud and concrete is pumped under the sinking concrete in order to support and lift the slab. Another option is a similar process known as polyjacking. Instead of a concrete mixture, polyjacking uses high-density polyurethane foam to fill voids and raise concrete.
While this type of repair can be cost-effective, making it enticing for homeowners, it isn’t a permanent solution. In most cases, this process is a band-aid for a few years, at most. The main cause for sinking concrete is unstable soil, and mudjacking only adds to that problem. Because mudjacking uses a concrete mixture, it can put additional stress on the compromised soil due to the added weight.
Due to the nature of mudjacking, there can be chunks of concrete that make it difficult to fill all gaps and voids beneath the slab. Leaving voids can result in further problems. Concrete is a porous surface, meaning that moisture can pass through the concrete. The materials used in mudjacking aren’t waterproof, and are subject to shrinkage, erosion, and material breakdown.
Since the process of polyjacking uses polyurethane foam instead of concrete, you never have to worry about adding unnecessary weight. This engineered foam can withstand all types of weather conditions, provides strength and stability to the soil, and is water-resistant.
Another benefit to using polyurethane foam is that there’s less time needed to cure. Polyjacking is a fairly quick and simple process, since the foam sets up almost immediately.
