Profile
Precast Concrete Headwalls
Althon specialise in designing and manufacturing precast concrete headwalls and have the most comprehensive precast concrete headwall range in the UK. The headwalls meet all the current water company requirements including Sewers for Adoption guidelines and Severn Trent Water specifications. The headwalls are designed and manufactured to BS EN 15258 & BS EN 13369 standards.
The benefits of using a precast headwall include a faster and safer onsite installation with less risk to the watercourse and environment, as concrete is not being poured at the point of installation. The headwalls can also be supplied with options prefitted at the factory including flap valves, penstocks, handrails, trash screens and safety grilles.
Each headwall can be viewed on the Althon website where a comprehensive selection of CAD and PDF files can be downloaded. The website also features an informative headwall video guide explaining the various headwall configurations and options. To help specifiers select the most appropriate model Althon provide a headwall specification tool on their website.
