Marshalls Headwalls

An important part of most SuDS drainage schemes, Headwalls prevent erosion at the point of discharge into a watercourse. These can be attenuation ponds, detention basins, rivers and swales. Made in Britain, Headwalls are a cost-effective alternative to in-situ structures, headwalls can accommodate pipe-work up to and including 900mm pipes and can be pre-fitted with closed coupled and cranked gratings and Hydro-Brakes, Penstock and Non-return flap valves depending upon your application.
