Every
30 years or so, something "new" comes along again.
The
technique known as "slabjacking" or "mudjacking," which
originated in the 1930's, has made an important comeback through modern equipment
and innovative techniques.
Mudjacking can reduce repair costs from 50% to 70% over the cost of replacement,
and is gentler to the surrounding environment.
Through
CRC's state-of-the-art volumetric mixers, a cementitious sand slurry
is pumped under pressure through small holes drilled in the concrete
slab. The slurry displaces air pockets, water and water-saturated soil,
leaving the raised concrete on a firm, permanent sub grade.
Lifting settled concrete is done quickly, usually in just a few hours.
Since there is no "break out," there is no concrete to haul
away, no grading, no forms to build, no curing time, no re-landscaping
and no landfill created. The
raised concrete can be walked upon immediately and driven upon in a
few hours. The finished work lasts about the same length of time replacement
concrete would last; several years down the road.
