What is polyjacking?
A type of polyurethane that reacts and expands to ensure there is no void between concrete slabs and also raise them, is called polyjack. It is primarily made from recycled materials and is moisture and decay resistant. Polyjacking is done by injecting polyurethane into concrete. It will flow under the slab and fill all the voids and gaps and eventually harden. To inject the polyurethane, you have to drill holes in the concrete which must be eventually patches up after the procedure is complete. Depending on the place where you are applying and purpose of the concrete slabs, you must choose the formula of the polyurethane accordingly. There are different types of products available. The application affects the choice of products.
It is important to make sure that the right amount of polyurethane is inserted underneath the concrete so that the level is raised perfectly. This is a great method of leveling concrete slabs without too much hassles. There are different qualities of polyurethane used for polyjacking and once you make the right choice, you can rest assured that your concrete slab will be raised in the right height. Also, it will not get dampened over the time.
