Headwall Design Tool 

Althon have launched a Headwall Design Tool to enable you to specify the headwall you require with associated factory fitted accessories.

We have produced a Headwall Design Request Form where you fill out as much information as possible. We will then send you a CAD & PDF drawing of your chosen headwall and will liaise with you to further refine the design to suit your specific requirements if required.

Headwall accessories include but are not limited to flap valves, penstocks, cascade panels, dissipation blocks, V notch weirs, handrails, gates & ladders.

Headwall Brochure 

Althon have released an updated headwall brochure giving a detailed overview of our range of precast headwalls.

The brochure was produced for the FloodExpo 2019 at which Althon exhibited. The brochure not only gives details on our range of concrete headwalls but also our other products such as flap valves, penstocks and drainage channels.

Precast concrete chamber with factory fitted penstock and actuator 

Althon precast concrete penstock manhole chambers are cast to order to suit any pipe openings and invert levels required. The benefit of using one of our concrete penstock manhole chambers is that we factory fit accessories to the unit prior to delivery to site. We can factory fit the penstock and actuator instead of manually using a spindle and T-Key if required.

For more information on our range of chambers visit the Precast concrete chamber section of our website or call us on 01603 488700

Headwalls with Cascade Panels 

We have recently manufactured a precast concrete headwall complete with a 8.5m long cascade panel for a project in Sunderland.

You can use our Headwall Specifier to find the headwall you require. We can then assist with pricing and design drawings detailing Cascade panels on our headwall drawings in CAD and PDF

Headwalls with Tideflex Valves 

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.
