Can I raise concrete myself?
Lifting a sunken slab may be necessary to level the surface. Hiring a professional service to lift, or jack up, the slab can be costly. You can avoid this expense if you do it yourself with the help of a jacking pump, which can raise the concrete slab to the needed level.

Patching fixes the safety issue without costing much, but the patch is sure to show.
Does foam jacking last?
The polyurethane foam Liftech uses to complete repairs will last indefinitely – through your lifetime and well beyond. It cures within minutes as a solid, impermeable structure that adheres directly to the concrete. It is not susceptible to fracture or failure.

What kind of mixture is used for slab jacking?
A specialized grout mixture is then pumped slowly into the holes. The voids under the concrete fill up and the grout mixture will become pressurized, hydraulically lifting the slab. The mixture varies, but it can contain limestone, sand, cement, fly ash and additives to prevent shrinking.
