Althon manufacture concrete headwalls with cascade panels as an extension to the spillway. Baffle blocks 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.

You can use our Headwall Specifier to find the headwall you require. On request we can provide pricing and design drawings for your chosen headwall with cascade panels
