Althon can manufacture concrete headwalls with Tideflex duckbill valves. We factory fit the duckbill valves to our precast concrete headwalls ensuring they fit properly and reducing installation time on site. Factory fitting duckbill valves to headwalls also means the headwalls do not have to be drilled on site which has great health and safety benefits.
You can use our Headwall Specifier to find the headwall you require. We can then assist with pricing and design drawings detailing Tideflex valves on our headwall drawings in CAD and PDF
