If your concrete is
sinking... there is a very good possibility that the concrete slab
was installed on poorly compacted fill dirt. Sub-surface erosion and
shrinking soils are also possibilities. However, as Sarnia and
surrounding area residents you are fortunate enough to have a
concrete leveler in your area, and therefore you should not have
spend thousands of dollars to replace the existing concrete. Sarnia
Paving Stone Ltd. can float a slab back to its original position by
pumping an environmentally friendly sand mixture beneath your slab.
Concrete leveling is a process, which hydraulically lifts your
existing concrete to its original position.
