Grain Bin Settlement Problems Common to Concrete Foundations Solved with NCFI’s Geotechnical Polyurethane Foam Technology
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.”

MOUNT AIRY, NC—In-ground parking garages in Dallas, TX experience the same thing: erosion of the soil beneath them, and silt infiltration that overwhelms and clogs the drainage system, thus causing more and worse erosion. The keys are catching it early enough, and choosing the right solution to keep it from happening again.
The three-story, in-ground parking garage at McKinney Ave. and Worthington St., the main thoroughfare of the Dallas’ “Uptown” area and home to some of the poshest apartments, business addresses, shopping, hotels, restaurants and bars, had silt and water infiltration, so the owners called in Edens Structural Solutions, Bixby, OK, with 30 years experience of structural lifting and repair. David Edens, company president, says they studied the problem and decided on geotechnical polyurethane foam. “Our solution was to use void-filling TerraThane geotech foam. It’s simple to apply, expands and cures in place, and is an excellent water and air barrier,” says Edens.

NCFI Geotechnical Foam, TerraThane, Helps Contractor Save Chicagoland Apartments With Minimal Disruption to Tenants
MOUNT AIRY, NC—A newly purchased 17-building apartment complex in Rolling Meadows, IL, built in the early 1960s, has seen plenty of tenants make their homes there. When new owners went about making renovations they discovered one 18,000 sq. ft. building suffering from voids in the soil beneath the slabs ranging from five inches to almost two feet in diameter caused by the stratified compacting of the historically hydric wetlands sedimentary soil, and water and sewer main breaks over the years. The voids caused some uneven floors and left the door open for future problems like mold.
