Howell Slab-jacking
What is Slab-jacking, and how does it work?
Slab-jacking is a proven alternative to concrete replacement dating back to the early 1930's.
Concrete settles for a variety of reasons. The #1 reason is that the base simply was not compacted properly before the concrete was poured. Over time the sub-base simply fails under the weight of the new slab and therefore settles. Slab-jacking is the proven answer. A series of small holes are drilled in the slab through which a grout and cement mix is pumped beneath the concrete slab. The grout under pressure depresses and helps stabilize the sub soil, fills the void and thus raises the slab to its proper grade. After the slab is lifted the holes are filled and patched with new cement.
