Althon have recently supplied a large narrow headwall to accommodate two 1200mm ID pipes factory fitted with HDPE flap valves for a project near Glasgow.

For this project they were able to use their standard narrow headwalls with an extension piece cast in the middle to create the width the customer required.

Althon can cast multiple pipe openings into any of their headwalls but if you cannot find a design you are looking for please use their Design Service. You can email them via sales@althon.co.uk or call on 01603 488700.
