Althon’s N20 range of precast headwalls are suited for installation where you have steep banks or little depth from back to front for installation
Our N20 range headwalls are manufactured to the same standards as our Sewers for Adoption headwalls and can be used on Section 104 Agreements where the sewers are to be adopted by the local water company.
There are three sizes of the N Range concrete outfall structures available, catering for pipe sizes up to and including 1500mm. Each size of N headwall comes with three depths of toe and five back wall heights with a wing wall profile of approx. 1:3 to suit most applications.
N20 precast concrete outfalls are cast to suit the diameter and type of pipe being used and can be provided with fixings cast in at the time of manufacture to accommodate gratings, trash screens, flap valves, penstocks, ladders, Kee Klamp® handrails and flow and depth monitoring equipment.
