The Solution (how it works)

Concrete Jack's skilled technicians are experts at slabjacking, a process that has been around since the 1930's, and which works by injecting grout material under sunken or unsupported concrete to raise it back to its original levels.  After being injected, the grout dries out and hardens to permanently support the affected areas.  Slabjacking works on almost any type of flat concrete, whether it be inside of a house, around a pool, on the top of your front porch or part of your sidewalk or driveway. 

It doesn't take much pressure to raise concrete, our employees are careful and our slabjacking equipment is compact, so we can work in almost any environment safely and effectively. 

The diagrams below show how the slabjacking process works. 

Drill:  Concrete Jack's slabjacking technicians drill strategically-placed holes through the settled concrete.


Pump:  Concrete Jack's custom grout mix is pumped through the holes to fill any voids under the concrete and raise it back up.  Grout is mixed onsite, which allows crews to customize each batch for the application. 


Patch:  Concrete Jack's slabjacking technicians patch the injection holes with cement.  Each of our crew trucks has a wide selection of colored cements, sand and organic materials to match patches to the existing concrete as closely as possible.

Concrete Jack has developed a process to raise some interior floors by injecting grout through the exterior walls below the level of the floor.  Information about this process can be found on Concrete Jack's interior floor repair website, SlabFloorLeveling.com. 

Skinny Machine

Concrete Jack's hydraulically driven pumps can maneauver into and through tight spaces (like this 31 inch gate) with ease.  Additionally, Concrete Jack's crews have multiple lengths of hoses that they can use to gain access to settled concrete that is not easily accessible.
