How Mudjacking WorksMudjacking
is a process of raising settled concrete slabs by drilling holes
through the slab and pumping a sand/cement mixture under the
slab. This process allows the slab to be "floated"
back to it's original position.
Mudjacking
is commonly referred to as slabjacking, grout pumping, pressure
grouting, and other similar terms, but they all mean the same
thing - raising settled concrete slabs.
Mudjacking
can be performed to raise a wide variety of concrete slabs:
driveways, sidewalks, patios, porches, garage floors, slab
garages, basement floors, slab houses, steps, swimming pool aprons
- the list goes on and on.
Lets
not forget about those pesky rodents that like to dig holes under
the concrete slabs. These voids that are caused from
animals, erosion, or just plain settlement also provide a lovely
home for such critters as ground squirrels, spiders, bees, mice or
rats, and a variety of other pests.

Step 1: A
pattern of 1 1/2 inch diameter
holes are drilled through the sunken slab.
|

Step 2: A
mixture of sand, clay and cement
under the slab. Once the voide is filled, the
slurry becomes pressurized and hydraulically
raises the slab to the desired height.

Step 3:
The holes are then patched
with cement.
