A one-piece reinforced concrete headwall available in a standard width of 1375mm and a height of 2035mm. Particularly suitable for steep embankments. Due to the relatively narrow footprint of the unit (back to front) it is advisable to fit suitable brackets to attach ground anchors. The unit can accommodate PCC pipes up to 750mm I.D. and plastic pipes up to 750mm I.D. Stainless steel sockets are provided for the attachment of gratings. Lifting points are cast in to each wingwall for safe handling using Althon lifting clutches. Galvanised mild steel angle can be fitted to the side walls in order to fit stoplogs and the back wall can be extended horizontally through the fitting of side wall extensions if required.

We cast the opening in the back wall of our headwalls to suit the pipe diameter and material of the pipe being used. We can cast multiple pipe openings, elliptical, square or rectangular culvert openings into any of our headwalls. We can also cast pipe openings into the wing walls of our headwalls.
