Polyurethane foam is great for leveling concrete. As the foam is injected under the concrete, it moves and expands. As the foam expands it fills any holes, cracks, and crevices beneath the concrete slab. Once voids are filled, the foam begins to lift the sunken concrete.
Full Answer
How do I calculate the expansion ratio of polyurethane foam?
Urethane Pour Foam Overview
- This two part liquid, expanding rigid urethane foam is a closed cell, pourable foam, which will resist the absorption of water.
- The densities shown refer to the weight per cubic foot of expanded foam (12" x 12" x 12").
- Once fully cured this foam can be laminated over with any type of polyester, epoxy or vinyl ester resin without melting.
Can expanding foam be used as insulation?
Yes, expanding foam can be used as insulation. Expanding foam can be defined as a two-component mixture composed of two materials that react when mixed. This causes the foam to expand and harden, providing an insulating material.
Can I install polyurethane foam myself?

- Take time to slowly install the foam in order to avoid overflow.
- Don’t try to wipe up spills and mistakes; wait until the foam has dried to scrape it off.
- Carefully inspect older homes before installing insulation to ensure it won’t cause moisture accumulation, which can lead to mold and rot.

How do you lift sagging concrete?
Mud jacking can lift a settled concrete slab by pumping a grout through the concrete and pushing it up from below. The process is sometimes called “slab jacking” or “pressure grouting”. 1 to 1 5/8th inch diameter holes are drilled through the sunken concrete block/slab at strategic locations to maximize lift.

Is PolyLevel better than Mudjacking?
PolyLevel can last indefinitely. It's inorganic, it's not sensitive to water so it won't wash away. Once the PolyLevel foam is injected, it's there to stay. Unlike the material used in mudjacking, the PolyLevel polymer won't break down or disintegrate, avoiding all of the problems of wash our and erosion.
