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

September 27, 2012 rockman 2

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.
