How it works…Raising sinking
concrete is a great alternative to replacement. We use the right equipment to
help minimize the mess and duration of the project. We start
by drilling several 1-1/2” holes in the surface of the sinking concrete.
There is a trivial amount of dust created by the drilling, but much less than
when grinding, cutting, or crushing the concrete. Using a
specialized pump and nozzle, pressurized grout is forced underneath the
concrete, filling any void area and hydraulically raising the slab until it
is level with surrounding areas. The grout hardens, helping prevent future
sinking. When the
concrete is level, the holes are patched and the surface is cleaned. Small
cracks may remain in the concrete, but these can be patched to create a
watertight surface that will help protect against future sinking. Replacing
concrete takes days or even weeks for the old concrete to be removed and the
new concrete to dry and cure. Raised concrete is usually ready for normal use
as soon as the following day. |
