Concast’s box culverts are rectangular (or square) shaped sections that are generally combined to form under passes, conducting streams, pathways and drains under embankments or roads. They are generally delivered to site in 2 m long sections, and joined together to form passage ways through the structure above them. They are designed to withstand the vertical and horizontal pressures from the earth and other superimposed loads, and are available in sizes up to 3.6m high and 6m long.
