FORT LUPTON, CO—An unfortunate inlet line break at one of Anadarko Petroleum’s hydraulic fracturing stations in Weld County, Colorado just north of Denver, allowed injection fluid to wash out the end of the pumping station and get beneath the concrete slab foundation causing erosion. The voids created beneath the slabs were from three inches to five inches and left the slab floor uneven. The general contractor for the station, Open Range Services, initially thought to use the legacy method of mudjacking, or pressure grouting: pouring a thick grout of mixed concrete and other aggregates into the void, or backfill, but the “mud” is heavy which can affect the surrounding soil, time consuming, and difficult to apply and clean, and backfilling would have required the costly process of ripping out the slab and replacing it. Instead, they contacted Pro Foundation Technology, based in Kansas City, MO, to learn more about a contemporary technology called “foamjacking” or “polyjacking,” which uses lighter weightgeotechnical polyurethane foam instead of grout.

New Solution Saves Money and Time Preventing Loss of Grain and Equipment DamageMOUNT 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.”

U.S. Forestry Service Saves Thousands with Use of TerraThane Geotechnical Foam by NCFI Polyurethanes at Seneca Rocks Discovery CenterMOUNT AIRY, NC— Seneca Rocks Discovery Center, the visitor’s center for the eastern U.S.’s most popular rock-climbing destination located in Pendleton County, WV, had a growing problem common to concrete slab foundations: erosion of the soil beneath the slabs created voids that left areas of the center with uneven spots and settled anywhere from one-to three inches. That led to cracks in interior walls, uneven floors, and trip hazards for the thousands of visitors to the area’s most popular scenic attraction. Seneca Rocks is a striking 900 ft peak that features over 375 mapped climbing routes varying in degree of difficulty from easier 5.0 to the hardest 5.13, and attracts climbers from around the world.

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.

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.
