Althon manufacture concrete headwalls with Tideflex duckbill valves. We factory fit the duckbill valves to our precast headwalls ensuring they fit properly every time and reducing installation time on site. Factory fitting duckbill valves to headwalls means the headwalls do not have to be drilled once on site.
We can fit multiple duckbill valves to a single headwall if required.
You can use our Headwall Specifier to find the headwall you require. We can then assist with pricing and design drawings detailing an appropriate duckbill valve based on pipe diameter.
