Uneven Concrete Slabs? PolyLEVEL to the rescue

Wednesday, July 9th, 2014 by Cassandra Santiago

As a young girl, I can recall consistently tripping over uneven sidewalks on the way to the park or scraping my knees from running around an uneven patio. Concrete slab settlement not only does damage to small knees, but can be an eyesore in and around your home. I used to think that this mismatch in concrete was due to earthquakes or some other natural disaster, but the cause is simple and quite common. Slab settlement is the movement that a concrete slab experiences when the soil below it can no longer support its weight. Soil changes and these changes result in uneven concrete.

What are the options?

The old fashioned way of mudjacking occurs by drilling a bunch of holes throughout the concrete slabs. Cement "mud" is pumped beneath the slab into these holes to raise the concrete. Unfortunately, this method can become quite messy. Mudjacking holes are about the size of a soda can, and when drilled every 2 feet, can really damage the look of the concrete. Sometimes the cement mud or slurry can splatter everywhere and is nearly impossible to clean. The cement slurry is heavy (more weight, more soil settlement) and takes a few days to cure, meaning that you cannot walk or drive on it until it is cured.

Concrete Replacement

Replacing the concrete is pretty self-explanatory, but is expensive, disruptive, and not a great solution. When your concrete settles, the problem was never the actual concrete, it was the soil underneath the slab that was causing the problem. If you put new concrete on the old soil, it is only a matter of time before the slabs settle again! Also, concrete replacement requires big heavy tools which can damage your property, lawn, and landscaping. Additionally, the new concrete will likely not match your old concrete, and we all like to match!

PolyLEVEL uses high-density polymers, rather than mud or slurry, to raise slabs back to an even level. This is done by drilling smalls that are smaller than a penny (and definitely smaller than a soda can) and injecting the polymers into the voids to raise the concrete. The polyurethane expands to lift and stabilize the concrete. PolyLEVEL is the best solution to your concrete because it uses less holes than other options, is lightweight, takes almost no time to cure, is waterproof, reduces trip hazards, and is environmentally friendly!
