100% indoors under 100% controlled conditions

To truly accelerate construction, greater control over the manufacture of prestressed precast concrete and precast concrete bridge components is required. At DECAST we are 100% indoors under 100% controlled conditions.

In order to determine the type of precast concrete bridge to use, span required is the determining factor. Smallest to largest span, the options are box culverts, DE-SPAN®, then bridge girders
