The soil under the concrete slab must be compacted and sufficiently robust; otherwise, the slab will continue to settle. You don’t want to have to continually replace the slab because it keeps sinking. You must address the underlying cause of the issue.
A variety of names for concrete lifting foam are used, including polyjacking, poly-leveling, polyfoam injection, poly-lifting, foam jacking, and slab jacking, among others. All of them are referring to the same thing or mostly the same process.
The following are six advantages of using concrete lifting foam.
After 15 minutes of injecting the foam, you may begin walking or driving on the concrete surface again.
Polyurethane foam injection is a less invasive method of lifting sunken concrete that does not need excavation.
Concrete lifting foam is lightweight and does not contribute to future soil settling, making it an excellent choice for a variety of applications. Polyurethane foam is lightweight, weighing between 2.5 and 4.0 pounds per cubic foot.
Polyurethane foam is non-reactive to soil or moisture, making it an environmentally friendly choice. No dangerous chemicals will be released into the environment, and your lawn will not be poisoned.
It is cost-effective to replace concrete since it entails chipping away at the existing slab, carting away the debris, bringing in concrete trucks, pouring the new concrete, and waiting for the new slab to cure. All of these costs add up quickly in total.
Concrete lifting foam is hydrophobic, which means it repels water. This implies that even when it comes into touch with water, it will continue to harden and remain steady.
