Precast concrete headwall.
Designed to connect pipe work discharging into open water courses.
Marshalls Civils & Drainage has developed an offsite precast concrete solution headwall system designed to connect pipe work discharging into open water courses, that offers a cost effective alternative to in-situ structures for connecting discharge from pipework into open watercourses. Precast headwalls drainage controls erosion and scour resulting from excessive velocities and turbulence and prevent adjacent soil from sloughing into the watercourse opening.
The headwalls can accommodate pipe-work up to and including 900 mm and can be pre-fitted with closed coupled and cranked gratings, with three sizes available; each with various height options. Bespoke precast Headwall options are also available.
Marshalls Civils & Drainage concrete headwalls pre-fitted options include Hydro-Brakes®, Penstocks and Non-return Flap Valves depending upon application.
Maintenance is low with only an annual check required. If needed, clean with water and some mild detergent to any exposed surfaces to main appearance. As with all concrete products, they will weather and natural coverage helps them blend into their environment.
