Slabjacking is the general term for lifting a sunken concrete slab by drilling holes and injecting material beneath it to fill the void and raise the concrete back to level.
In depth
Slabjacking is the umbrella category that covers both modern polyurethane injection (polyjacking) and traditional mudjacking. The concept is the same in both cases, pump a lifting material under the slab until it rises, but the material determines the result. Polyurethane foam is lightweight, erosion-resistant, and fast-curing; mudjacking slurry is heavy and slower.
Because slabjacking lifts the existing concrete rather than removing it, it is a fraction of the cost and time of full replacement and preserves the original slab.
How Acme applies it. Acme performs slabjacking exclusively with polyurethane, choosing among several foam formulations to match each slab’s size, load, and soil conditions.

Frequently asked questions
What is the difference between slabjacking and mudjacking?
Mudjacking is one type of slabjacking that uses a heavy cement-and-soil slurry. Slabjacking is the broader term and also includes polyurethane foam injection, which is lighter and longer-lasting.
Can any slab be slabjacked?
Most flatwork, including sidewalks, driveways, patios, and garage and interior floors, can be raised, provided the slab itself is structurally sound and not badly broken up.
