Boxes

Heidelberg Materials produces a range of precast box culverts that can be used for a variety of horizontal and vertical applications. Primarily intended for use as a horizontal conduit where headroom is limited, precast boxes can significantly cut the costs by reducing or eliminating formwork, dewatering, traffic control and curing when compared to cast-in-place concrete.

Heidelberg Materials Manufactures Precast Boxes To Meet The Following Standards:

ASTM C1433 Standard Specification for Precast Reinforced Concrete Box Sections for Culverts, Storm Drains, and Sewers
CSA S6-06 Canadian Highway Bridge Design Code
