SFA27 D precast concrete headwalls are designed to comply with Sewers for Adoption guidelines for pipework discharging into open watercourses for plastic or clay pipework up to 1800mm and concrete pipework up to 1600mm. SFA27 D concrete headwalls have a backwall height of 2350mm and are manufactured in 2 pieces. We cast the opening in the back wall of our precast 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 precast concrete headwalls. We can also cast pipe openings into the wing walls of our headwalls. We can factory fit all our precast SFA headwalls with Kee Klamp® handrails, Sewers for Adoption specification gratings, flap valves, penstocks and other flow control devices.

All Althon Sewers for Adoption precast headwalls are available with either 300 or 500mm thick toe extensions. If you cannot find the drawing or information you are looking for please contact us. The SFA27 D headwall weighs 8900kg / 4450kg per half.
