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.


Typical precast elements include:

  • Wing Walls

    Wing walls are sloped retaining walls, which are placed at the entrance to a culvert, to allow the soil to incline to the full height in the area.These units are often combined with our head walls and culverts to form the entrance to culvert structures

    Head Walls are used at the entrances to box culverts to retain soil above the entrance. They are cast as thin wall panels or beams, which bear directly on top of the culvert
