Inland Pipe 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.

Precast boxes can be designed for various depths and loading conditions including truck, railway and airplane loads. Similar to concrete pipe, precast box culverts are available in unique configurations including mitre bends, wyes, cast-in baffles, and manhole access openings.
