Concrete raising is done by pumping
cement grout underneath sunken concrete slabs to restore them to
their original grade. It's as simple as 1-2-3!
1. A pattern of 1 1/2-inch holes are drilled through the slabs.
2. A mixture of limestone and cement
is pumped under the slab, filling the void. The grout becomes pressurized,
hydraulically raising the slab.
3. The holes are then patched with
a top patch cement. Since slabs are not being removed, there is
little mess, no inconvenience or color change. The area can be used
immediately after the slabs are raised.
How much does slabjacking cost?
Slabjacking is usually less than
half the cost of pouring new slabs. However, the savings may be
even greater, since demolition and removal costs are eliminated,
and no landscaping is required.
