By proposing multiple repair options for most projects, Concrete Jack leaves you in control of deciding how to balance your organization's priorities such as budget and time.

Whether it is void filling under a curled slab using polyurethane foam, using a soil-based grout to raise and support a sagging floor, or filling large voids with lightweight cellular concrete, Concrete Jack’s crews have the right experience and tools to help maximize operational efficiency of your facility.

Benefits of industrial foam jacking

Concrete Jack's high density polyurethane concrete leveling crew recently raised the settled floor of a data center in Sterling, Virginia.  The settled floor slab, which spanned from a battery storage room into a hallway, including an area under a raised floor, had settled about 3/4 of an inch, causing a door frame to rack.  By injecting polyurethane foam through 5/8" holes, which were drilled using dustless drilling, Concrete Jack was able to raise 250 square feet of flooring in about three hours, from start to finish.  The area was open to continual use during the lifting process.  After completion, the only evidence of a repair being done were three 5/8" spots of fresh concrete, where the injection holes were drilled.

Injected polyurethane foam is an excellent choice for stabilizing joints in floors that have curled or experienced settlement.  The only equipment to enter the work area is a 2" diameter hose bundle, so there is no exhaust or other contaminant introduction.  By using vacuum systems during drilling of the 5/8" injection holes, dust introduction is minimized, as well.  Concrete Jack has multiple densities of foam, however all harden with minutes of injection, so repaired areas can be opened immediately to traffic.  Irrespective of savings from minimizing downtime, leveling industrial floors costs around one third the price of demolition and repour.
