Headwalls
Althon manufacture the largest range of precast concrete headwalls in the UK for pipes, culverts and box culverts.
Precast headwalls are an important part of most SUDS drainage schemes, preventing erosion at the point of discharge into watercourses such as attenuation ponds, detention basins, rivers, ditches and swales.
