Openings in our rectangular concrete headwalls are cast to suit the pipe material and diameter being used on site. We can also cast the opening to a specified invert level if required. Our rectangular precast headwalls can be factory fitted with a range of accessories such as flap valves, penstocks, Kee Klamp® handrails as well as trash screens and outfall safety grilles.
