Althon have recently supplied a large headwall to accommodate a 1500mm ID pipe factory, fitted with HDPE flap valves and bespoke sections.

For this project we were able to use one of our standard narrow headwalls with two extension pieces cast on the left hand side, to create the angled spillway the customer required.
