Althon manufacture concrete headwalls with cascade panels as an extension to the spillway. Cascade panels slow down the flow of water discharging from the pipe down the bank before entering the watercourse.  

We have standard size and design cascade panels available for various headwalls and can assist with designs for non-standard applications.

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

You can also visit the Precast Headwalls section of our website.
