Althon manufacture concrete headwalls with multiple pipe openings. We can cast more than one pipe opening into any of our headwalls. The only restriction is the space on the headwall for more than one pipe opening. Pipe openings can be set at any invert level anywhere on the back wall of the headwall. We can also cast openings into the side wing walls of a headwall.

Being able to cast several openings into one headwall means that you can have more than one pipe discharging out of a single precast headwall unit.

If you would like to specify a headwall with multiple pipe opening please fill out our Headwall Design Request Form and we will email you back CAD and PDF drawings.
