What is Mudjacking or Slabjacking?

Actually, they are terms that are used interchangeably for a system of raising concrete that got it’s start in the late 1920’s. Of course, it has greatly changed since then. Although the methods have changed, the results are still the same – level concrete.

Mudjacking & Slabjacking

How does it work?

1. Small holes are drilled into the slab where it has settled.

2. A slurry substance is hydraulically pumped through the holes to fill any voids, and the hydraulic pumping causes the slab to raise back to it’s original level.

3. The holes are cleaned out and patched with a cement-based mixture.


What are the advantages of mudjacking vs. replacing concrete?

Raising concrete is typically half or less of the cost of replacing.

Under normal conditions you can use the concrete right away instead of dealing with the inconvenience of waiting for a new slab to cure.

The lawn is not damaged by raising the concrete as it would be with preparing to pour a new slab.

The slabs will all still have the same color as opposed to having some new slabs and some old slabs that will not match.

If you pour new concrete – it is just a matter of time before it cracks and settles again.
