/ Concrete Raising

The Basics of Raising Concrete


Companies have been raising and leveling sunken concrete as an alternative to concrete replacement for nearly 80 years. The older method, referred to as “mudjacking”, uses various materials (depending on the contractor) including sand, limestone slurries or mortar mixtures pumped through several large holes drilled in the concrete slab. This method lifts the concrete and fills the voids. Although “mudjacking” has been around for a long time, it has many limitations.

Modern Concrete Raising:  Polyurethane Foam Injection

Once protected by US Patent, an advanced method of concrete raising using polyurethane foam injection was reserved primarily for Department of Transportation projects. This technology has now become available as a superior solution in raising sunken concrete for every industrial, commercial and residential application imaginable. Raising sunken concrete with polyurethane foam injection is fast, clean and it outperforms older methods and materials on many levels.

Lifting Sunken Concrete:  The ACME Advantage

Acme Concrete Raising & Repair uses only modern technology. Polyurethane foam injection permanently raises and levels sunken concrete structures. Made from recycled material, a two-part polyurethane is injected through small holes strategically placed in the structure.

Still in liquid form, the polyurethane flows easily between the concrete slab and existing subbase. Immediately following injection, a chemical reaction takes place creating a dense, closed cell foam that expands and lifts the slab back to its original position. During the expansion process, the foam fills all voided areas and creates a new, permanent subbase in about 15-minutes. This new subbase is impervious to numerous environmental factors such as freeze, thaw, water intrusion, washout or cracking.
