Standard Precast Concrete Headwalls Video

Althon standard range precast concrete headwalls can accommodate pipework up 2100mm. We can cast in multiple pipe openings into our headwalls if required. As standard we will cast in the openings 100-150mm above the spillway of the headwall. However we are able to cast in the opening for the connecting pipe or pipes anywhere on the backwall of the headwall or in the wingwalls (sidewalls). Drainage pipes discharging into open watercourses should be fitted with a concrete headwalls. Althon precast concrete headwalls are fast and easy to install.

All of our precast headwalls can be factory fitted with accessories such as outfall safety grilles, Kee Klamp® handrails, flap valves and penstocks. We are also able to provide additional precast elements on our headwalls such as diffuser blocks, stepped baffle blocks, extended spillways with cascade panels and in some instances precast steps. We are happy to help design a precast concrete outfall headwall with you to suit your site specific requirements.

Althon have the largest range of precast headwalls with associated accessories available in the UK. If you cannot find the headwall you are looking for please get in touch with us and we will be happy to assist. We are constantly uploading new drawings to our website and new precast headwalls to our range and we are confident we will be able to provide the headwall you require.
