Althon manufacture concrete headwalls with penstocks. We factory fit the penstocks to our precast headwalls ensuring they fit properly every time and reducing installation time on site. Factory fitting penstocks to headwalls means the headwalls do not have to be drilled once on site.

We can fit multiple penstocks to a single headwall and offer penstocks fitted to concrete headwalls in HDPE & stainless steel grade 316L

You can use our Headwall Specifier to find the headwall and penstock combination you need. There you will be able to download datasheets as well as CAD and PDF files.

You can also visit the Precast Headwalls section of our website or the penstocks section
