Althon manufacture concrete headwalls with flap valves. We factory fit the flap valves to our precast headwalls ensuring they fit properly every time and reducing installation time on site. Factory fitting flap valves to headwalls means the headwalls do not have to be drilled once on site.
We can fit multiple flap valves to a single headwall and offer flap valves fitted to concrete headwalls in HDPE and cast iron.
You can use our Headwall Specifier to find the headwall and flap valve combination you need. There you will be able to download datasheets as well as CAD and PDF files.
