Concrete Leveling Products

Leveling sunken concrete can involve a wide range of techniques and materials

What happens when a concrete slab sinks or settles? Whether sunken concrete occurs in a patio, sidewalk, garage, warehouse or elsewhere, it's usually important to correct this structural problem as soon as possible. There are a number of ways to do this.

It's important to choose a cost-effective concrete repair technique that provides lasting results

Knowing the difference between concrete repair techniques is key to making the best decision for you and your home.

Whether you're an engineer, a homeowner, a real estate agent or a factory foreman, the questions you ask about concrete leveling are likely to be the same: How much does concrete leveling cost? How long will it take? How soon will I be able to use my (patio, sidewalk, driveway, etc.) after the repair? Is the repair permanent?

Most of the concrete leveling techniques result in permanent repairs, but other factors can be quite different, as you'll see.

• Concrete replacement qualifies as the old-school repair. Instead of attempting to raise a sunken slab, the slab is partially or completely demolished and then replaced with new concrete. Concrete replacement has the disadvantage of taking a long time. Erecting forms, installing proper reinforcement, pouring the concrete, and waiting for the new work to harden and cure can take several days or more.
• Mud jacking goes by other names, such as slab jacking and grout pumping. This concrete leveling product is a slurry of liquid grout (which can include dirt, Portland cement and sand) that is pumped under a sunken slab to force it upwards by hydraulic pressure. Large holes are drilled in a sunken slab to provide clearance for the pumping nozzle. Care must be taken to prevent messy spillage through gaps and cracks. Once mudjacking is complete, the surface shouldn't see heavy use until the grout mixture has hardened.
• PolyLevel® is sometimes mistakenly referred to as slab jacking. This concrete leveling product is a two-part foam engineered to expand immediately upon injection beneath a settled slab. Injection holes are much smaller than those required for mud jacking. In action, PolyLevel® expands to many times its original volume, forcing the sunken concrete back to its original level. Within a matter of minutes, the expanded polymer hardens and reaches 90% or more of its final strength. This makes it possible for the restored surface to regain full functionality right away.
• Re-leveling grout is sometimes used to "skim-coat" sunken concrete as an alternative to slab raising. The settled slab is simply left in place, and fresh grout or (in some cases) concrete is placed over the old surface. Problems with grout releveling include poor adhesion to the old concrete (which can cause the new material to crack or detach), unattractive appearance and added weight, which can cause further sinking action.
• Concrete grinding is a leveling technique that grinds away protruding edges and corners, primarily on concrete sidewalks where slab sections have settled or heaved. This repair sometimes has to be repeated, as slab sections continue to move up or down. It also gives the repair area a strange faceted appearance.
