Precon’s precast concrete headwalls offer a cost effective alternative to in-situ structures for connecting pipework discharging into open watercourses such as rivers, ditches, ponds and swales. These precast headwalls allow contractors to quickly complete pipe runs without extending time spent in environmentally sensitive areas, and preventing the requirement of using the costly cast in place option. Precon’s headwalls come in standard sizes for 200mm to 600mm diameter pipe and are available to suit most pipe types.
Headwalls can be configured with dissipaters, handrails, grillages and other custom items such as bolt on icd plates, sluice or flap gates. Precast headwalls also control erosion and scour resulting from excessive velocities and turbulences.
