Liftech Uses Polyurethane Foam to Level Industrial Freezer in Sub-Zero Temperatures

Harlan Bakery in Denver is one impressive facility, producing enough bagels each day to supply many of the largest retailers in the Denver Metro. Chances are, if you live in Denver and eat bagels, you have been fed by Harlan Bakery. 

Unfortunately, even as well-oiled of a machine that this facility is, sinking concrete can wreak havoc! One of their freezers had a sinking corner, causing their forklift to slide about and create not only an operational slowdown but a safety hazard as well. So Harlan did what thousands of residents and large facilities in Denver do when their concrete is sinking, they called Liftech!

Liftech was able to assess the sinking floor with their state-of-the-art estimating software and come up with a lifting solution to bring up the floor and get their bagels moving fast again. The solution: Inject 730 lbs of polyurethane foam, supplied by NCFI, in the sinking corner, around the perimeter of the walls, and fill the additional voids between the wall and the center of the concrete. The foam fully cures within minutes and will be strong enough to support anything you can think of. The fix also comes with a 5-year warranty provided by Liftech, far more than you would ever get with a new concrete floor.

A major concern was that this freezer was kept sub-zero, and polyurethane foam can have difficulty reacting even just below freezing temperatures. But Liftech uses heated hoses that we’re able to keep the chemical warm enough to lift the floor back to level.

The hoses that Liftech uses for our concrete leveling are over 200 ft long, making them great for reaching floors in large commercial buildings. The trucks can be parked on the perimeter of the building and have minimal equipment to cause disruption to business operations.

So instead of shutting down your facility for a lengthy period of time to remove and replace concrete, just level it with polyurethane foam. Liftech was done in less than 4 hours and had the floor within a half-inch of original grade, up from over 4 inches down! 

And don’t worry bagel lovers, we wore our hairnets.
