Unlike short-term options like sludge sequestration, PolyLevel is a solution that will last. Under the right conditions, the polyurethane foam jack can last a lifetime. When approaching your project, it is important to address issues that could cause the life of the polyurethane foam lifting process to decrease. We recommend that you find the right contractor to help you balance longevity, costs and ensure that your project is completed to your satisfaction.
Despite these benefits, you may be wondering how long the foam lift lasts. While mud theft usually lasts 2 to 5 years, polyurethane can last much longer if properly maintained. The lifting solution should last as long as the concrete surface. The trick is not only to lift the sunken concrete, but also to remedy the cause of the subsidence.
You can repair a crack or lift a concrete slab a thousand times, but if you do not take care of the cause of the problem, you will continue to repeat yourself as you throw money out the window. Most often, the soil under the slab is weak or lacking. The polyurethane foam that we inject under the slab expands, filling the void, compressing the weak soil and sealing the bottom of the slab against water and moisture. In almost all cases, mud extraction provides better stability and support of concrete in the long term than injections of polyurethane foam.
Since more voids are filled with a natural sand slurry, and because this sand slurry does not harden over time like polyurethane, mud extraction provides more durability and long-term support for concrete. Traditional mud lifting is more messy and does not last as long as mud is often washed and the concrete slab may sink again when the void forms a second time. This results in more concrete being used, as well as an increase in labor to prepare the site for concrete pouring. So it's only natural that you want to know that you can count on Liftech's polyurethane concrete leveling or foundation repair solutions to last for the long haul.
PolyLift or Polyjacking uses high-density geotechnical expandable foam to lift and stabilize concrete slabs. If it helps protect your concrete, the polylift will last longer, providing you with years of concrete support. It takes an expert to find the right places to inject the polyurethane foam, in addition to the right amount. Leveling a concrete slab by using polyurethane foam is quick and not too challenging if you have the right tools% 26 time to get the job done.
Definitely, each method has benefits, but the duration of the repair has more to do with making sure that the original cause of concrete subsidence has been addressed. Firstly, it is lightweight, which makes it a good choice in situations where the weight of concrete would further damage a structure. To repair the problem, contractors can drill a hole in the concrete and inject a filler material to eliminate gaps and raise the surface of the concrete. This can often include adding soil around the slab or adjusting the downspouts to move water away from the concrete.
The lifting of polyurethane concrete leads to a faster and more durable repair, and can reach more areas than mud theft.
