Althon have a new range of precast concrete headwalls that are designed to suit steep banks or site conditions that have little depth from back to front for installation.

Their new N range of headwalls are manufactured to the same standards as their Sewers for Adoption headwalls and can be used on Section 104 Agreements where the sewers are to be adopted by the local water company.

They cast the opening in the back wall to suit the pipe diameter and material of the pipe being used. Althon can cast multiple pipe openings, elliptical, square or rectangular culvert openings into any of their headwalls. They can also cast pipe openings into the wing walls.
