Althon can accommodate multiple pipe openings into any of its precast concrete headwalls, as long as there is enough space in the backwall or wingwall to do so.

All of Althon's precast concrete headwalls are made to order allowing clients to choose the size and position the pipe work needs to be.

The company's Headwall Design Service can then be used to find the required headwall then, on request, pricing and design drawings can be provided for the chosen headwall showing more than one pipe opening.
