How Does Slabjacking Work?

1. A series of small diameter holes are drilled in the concrete surface. These holes are strategically placed to maximize the concrete lift. 
   
   
   
   
2. A mixture of sand and cement known as grout, is pumped under the slab. Once any void is filled, the grout becomes pressurized and hydraulically raises the slab to the desired height.
   
   
   
   
3. The holes are then patched with cement.
