Solid Foundation for Grain Storage
URETEK ICR was contacted regarding settlement in two identical 1.5 million bushel grain flat storage buildings. The overall structure dimensions were 600 ft. long by 135 ft. wide with a Quonset style roof . Below the floor of the storage buildings, a tunnel with conveyance system and a series of aeration tunnels were installed to facilitate moisture control and grain transport.

NCFI Polyurethanes and the Geotechnical and Geoenvironmental Business
NCFI Polyurethanes’ TerraThane Product Line Quickly and Quietly Improving Bottom Line for North American Geotechnical and Geoenvironmental Businesses
MOUNT AIRY, NC—The distinctly American company, NCFI Polyurethanes, is known for pioneering innovative, improved, and unique uses for one of their main product offerings: polyurethane foam. Since the company’s scientists and engineers began formulating polyurethane foam back in 1967, other chemical systems companies have been saying, “wonder what they’ll come up with next?” So, it was really more of a “holy cow” moment in the 1990s when NCFI began formulating foam systems for geotechnical uses: highway and roadway repair, bridge approach repair, concrete lifting, leveling and void fill. And it’s no surprise that like all NCFI product lines, TerraThane geotechnical foam is quietly changing the way entire industries work for the better.

Grain Bin Settlement Problems Common to Concrete Foundations Solved with NCFI’s Geotechnical Polyurethane Foam Technology
New Solution Saves Money and Time Preventing Loss of Grain and Equipment Damage
MOUNT AIRY, NC—Soil consolidation and settlement happens. It’s a fact of farm life. Secondary consolidation slowly forces water out of the spaces between soil particles. As this happens, soil particles move close together and settling occurs. Floors drop and become uneven. Newer grain silos and bins are using concrete floors instead of metal, and as secondary consolidation occurs beneath them, depressed or “settled” areas, form within the bin. Grain accumulates in the depressed areas, but cannot be retrieved by the bin sweeper. In fact, the sweeper, a kind of auger that transports grain up from the floor, can become damaged from prolonged exposure to the uneven floor.
This is exactly what Kirk Roberts of CJGeo, a Williamsburg, Virginia-based commercial foundation repair and geotechnical contractor, found when he got the job to repair the foundation of a massive 106-foot diameter grain bin at a poultry processing facility on the Eastern Shore of Maryland. “Once they removed the hundreds of thousands of bushels of grain, we found the floor had dropped some three inches in one section of the bin leaving a large pocket of grain out of reach of the bin sweeper.”
