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.

Side-hill retaining walls refer primarily to fill-walls built partway down the sides of an existing slope or embankment. They are encountered in roadway and rail widening projects as well as site development but usually in steep terrain. This article provides an overview of the problems, failure mechanisms, investigation approaches, analysis tools and wall type alternatives for these structures. Click through to read the article!
According to Silicon Valley’s MercuryNews.com, a [very lucky] worker suffered minor injuries when the crane he was opperating toppled down an embankment. The accident apparently occured on a CALTRANS project as the crane was lifting a 10,000-lb pile when a "wood retaining wall" gave way. It sounds like they were constructing a soldier pile lagging wall with steel h-pile soldiers and wood lagging. (Photo by Donna Jones/Sentinel)
