Concrete slab jacking information

Helping you learn more about concrete restoration and concrete repair.

A process called slab-jacking is a method of concrete repair for when a slab sinks into poorly packed soil, or eroded soil, or some such. Very often, even the best-poured slab will sink into the earth a little, and it’s rarely any problem, but when it sinks so that there is a noticeable difference in its level, something should be done. Someone who performs this service, a “slab-jacker” can save you the money of having to replace the slab. How do they do this? Well, it’s really not all that complicated.

With very little disruption to any landscaping, they pump what amounts to complex sand (it also has gravel and cement as well as just sand) below the sinking slab and it rises in a matter of a few hours back up to the surface, where it is supposed to be, and probably will not sink any further, as the mixture below it is dense and sturdy. The kind of pump used is powerful enough to lift thousands of pounds, so even moving things off the slab is unnecessary.

Much faster, and much easier then tearing it up and relaying a new slab, don’t you think?
