How Slabjacking 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. Concrete Jack doesn't just raise and level interior floors; our technicians have successfully raised acres of concrete ranging from kitchen and garage floors to sidewalks and pool decks.
Concrete Jack's slab jacking process is safe to use in all types of environments. It has been used to raise floors inside of basements, garages and kitchens and was even used to raise the floor inside a dining room at a retirement facility, while the residents were eating their meals!
