Hillsborough County Florida is using a mix of expanding polyurethane foam and conventional cement grout as a more cost effective means of filling sinkholes. Officials say the mix uses 30 to 40% less grout adding up to a 30% cost savings. The article in the Tampa Tribune did not indicate the contractor or product name that they are using but apparently several agencies in California and other states are using the same material.

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.

Posh Dallas Parking Center Saves Millions with TerraThane Geotechnical Polyurethane Foam by NCFI
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.
