Precast concrete is a durable and versatile building material, but parking garages are one of the most demanding applications even for concrete. To combat the corroding effects of chloride-laden water, High offers a true breakthrough: CarbonCast Double Tees, with C-GRID® carbon fiber mesh replacing conventional steel mesh flange reinforcing.

Because C-GRID does not corrode, double tee flange degradation from cracking and spalling is a non-issue. At the same time, pretopped CarbonCast Double Tees can use less concrete cover, reducing weight up to eight percent and reducing embodied energy, superstructure and foundation costs.

CarbonCast can:

• Reduce foundation loads
• Support elements and connectors that can be designed for lighter loads and/or wider bays
• Enable increased clearance under shallower tees or decreased structure heights
• Lower shipping and erection costs
• Require less maintenance and perform better, long-term
• Offer greater crack resistance, superior steel reinforcing protection, and faster fabrication and erection compared to cast-in-place
• Be cast to control drainage and minimize ponding
• Better withstand the abusive forces of man and nature—from wind, acid rain, and road salt to earthquakes and fire
• By using MEGA-TEEs and long spandrels, reduce the number of joints to be maintained
• Maintain its original appearance for years, with no significant discoloration, staining, or surface decay when properly maintained

CarbonCast is an excellent choice in the Mid-Atlantic and Midwest regions, where it withstands wintry weather conditions and coastal climates and can be erected year-round.
