Now is the time when we start to hose down the patio furniture, put new plants out, and stock up on charcoal. The best time to enjoy your home is during the warmest months when you can sit outside with your friends and family and admire your beautiful surroundings. Sometimes, the annual tidy up leads to an ugly discovery — unlevel concrete. Hopefully, you discover an unlevel concrete slab when you brush away a collection of dead leaves and not when your child hits it with their bike and falls off.
Luckily, leveling concrete is quicker and easier than ever before with the PolyLevel polymer injection process. Before the end of the day, you’ll have forgotten that horrible safety hazard was even there.
Signs of Concrete Settling
Usually, when there is a huge chunk of settled concrete around your house, you will recognize it without any help. Below are a few clues just in case you aren’t sure what you’re looking at:
- Sinking concrete steps or sidewalks
- Cracked, bumpy, and uneven driveways or patios
- Cracking and sinking sections of slabs
- Washout of soils under concrete slabs
- Repeated cracking of concrete slabs
A Better Method
In the past, concrete was leveled by contractors who relied upon mudjacking, aka slab jacking, concrete lifting, concrete raising, grout pumping and slab leveling. This method entailed pumping grout or heavy concrete slurry under the settled slab to raise it and hope it wouldn’t continue to settle in future months or years.
The PolyLevel Difference
The best method now is to use PolyLevel, a polymer injection which takes the traditional mudjacking concept and fuses it with modern and innovative technology to lift concrete slabs to a level position. This method uses much less weight and disruption than the mudjacking or slab jacking process. Besides actually fixing the issue, Polylevel has a variety of added benefits such as environmentally safe, affordable, waterproof (to prevent future erosion), quick, no mess, and a permanent solution.
The Process in Four Easy Steps:
- Tiny 5/8 in. holes are bored through the sunken concrete.
- Injector port is installed in each hole.
- Foam is injected into the port to lift the slab.
- Port is removed and the holes are cleaned and patched with new cement.
This is an extremely unique and innovative solution. Polyurethane foam very lightweight, yet sturdy — it has the lifting force of 6000 lbs. per sq. ft. and has an expanding quality that allows it to fill in every little area to keep your slab level for life. The foam begins to expand immediately and within minutes it will begin to harden, reaching 90 percent of its final strength in under 20 minutes (so by the end of the day you can park your car or know your kids are safe riding their bikes on it).
Once the foam is hardened and cured, it will not absorb water or alter in dimension over time and is a completely inert material, meaning that it will not leech harmful chemicals into your soil. As well as not ruining your soil through chemical leakage, the foam is so light that it fills the loose soil so well that it will not erode or shift over time like a traditional slurry fill would.
