Mudjacking or slabjacking is a concrete repair process involving lifting concrete from below the surface. The concrete raising process involves drilling holes, approximately 1 5/8″ in diameter, through the top surface of the concrete. Material is then injected into the holes using a hydraulic pump. Once the void space below is filled, the lifting process is initiated until the desired height or pitch is achieved. After the slabs are lifted, the holes are patched, the surface washed down, and the process is complete.

Polyurethane Foam Jacking

Foam Jacking, similar to Mudjacking is performed by drilling 5/8″ holes through the surface of the concrete slab. A high-density polyurethane foam is then injected beneath the surface where it expands and hardens to lift slabs and fill voids. The expanded foam is very strong and long lasting. As with mudjacking, the drill holes are then filled and patched, but are less noticeable than traditional mudjacking holes.

Void Filling

Empty space which exists under a slab of concrete is called a “void.” Voids can occur over time from erosion, washout, back-fill settlement or animal/pest intrusion. You may notice a void when you step on your concrete, hear hollow-like sounds, or visibly see an obvious void along the edge of a slab.

Void Filling is accomplished in similar fashion to mudjacking. However, the goal is to fill and support beneath the slab rather than raise it. During the void filling process, holes are drilled through the top surfaces of the concrete slab and material is pumped beneath the slab until back pressure is achieved allowing for an adequate fill beneath the surface. Often times, the surrounding area will need to be back-filled to buildup the surrounding area to prevent future, subsequent voids.


Caulking is the process of sealing joints and cracks. Caulking concrete surface joints and cracks is recommended as a maintenance issue to provide protection from water and pest intrusion.

The caulking process involves
1) Removing Surface Debris
2) Clean cracks using a broom or leaf blower
3) Fill the crack with a polyurethane concrete caulk/sealer
