PolyLevel® is installed in a simple 4-step concrete lifting process that results in a safe, secure and level concrete slab. Step 1: Small 5/8-in. holes are bored through the sunken slab. Step 2: An injector port is installed in each hole. Step 3: High-density foam is injected into the port, whereupon it expands and lifts the slab. Step 4: With the port removed, the holes are cleaned and patched with cement.
Mud jacking involves pumping a mortar-based mixture of "mud" or "slurry" underneath a settling slab. This injected material is a mixture of water, soil, sand and Portland cement that cures to become a solid, stable fill.
