Parking Structure

A 50-year parking garage you can believe in

For years, architects, engineers and parking consultants have looked to precast double tee parking decks as a superior alternative to cast-in-place decks. Precast double tees offer unmatched consistency, erection speed and long-term durability in addition to aesthetic flexibility, fire resistance, low maintenance and high overall value.

George Washington Auto Park, Winchester, VA, includes 140,000 square feet of CarbonCast Double Tees.

Parking structures represent one of the most demanding applications for concrete
They’re exposed to the elements 24 hours a day, seven days a week. They’re expected to support hundreds or even thousands of vehicles—including heavyweight SUVs. They face a barrage of corrosive agents such as salt used to clear roads from winter precipitation and chloride-laden air and moisture along coastlines. Although corrosion isn’t a problem everywhere, it has the potential to be a garage owner’s worst nightmare.

CarbonCast® Double Tees from AltusGroup can eliminate worries. By replacing welded wire mesh in the flange with non-corrosive C-GRID, garage owners do not have to worry about the potential for concrete degradation, cracking or spalling

At the same time, CarbonCast Double Tees can use less concrete cover in their flanges—reducing weight up to 8%, which reduces embodied energy and associated greenhouse gas emissions.


The Ballantyne Parking Deck, Charlotte, NC, is 753,000 sq. ft. and features CarbonCast Double Tees.
