When choosing a method for concrete leveling, there are two main options, Polyjacking and Mudjacking. While both options will get the job done, some differences are important to how well and how long the repair will last. 

Polyjacking uses high-density polyurethane expanding foam to lift and level concrete slabs. The material and equipment used are very similar to what is used for spray foam insulation; however, the foam used for lifting concrete has a much stronger formulation. The first step in the poly jacking process is to drill small holes in the damaged concrete slab. Once the holes are drilled, high-density foam is sprayed underneath the slab. This foam then expands to fill voids and lift the concrete slab back to its original position. The foam we use can expand up to 7 feet at each injection point and will harden to create a permanent repair for your concrete slab. 

Mudjacking is a method for concrete leveling that uses sand, cement, and other materials to raise and level a slab. The materials are mixed into a slurry and pumped into drilled holes, similar to the process of poly jacking. Mudjacking is best suited for concrete in good condition but no longer level. However, there are many projects where Mudjacking is not the best choice. Mudjacking won’t work for large or heavy slabs and can erode over time due to the organic nature of the slurry. 

This is why our team at Force Masonry Construction uses poly jacking for concrete leveling. Unlike mudjacking, poly jacking won’t degrade over time. It has a high resistance to temperature changes and is a permanent fix for sinking concrete around your home or business.
