Althon manufacture concrete headwalls with precast baffle blocks on the spillway. We factory fit the baffle blocks to our precast headwalls ensuring they fit properly every time and reducing installation time on site. Baffle blocks slow down the flow of water discharging from the pipe across the spillway of the headwall before entering the watercourse.  

We can fit baffle blocks to the spillway of a headwall in any arrangement required, space permitting. Usually we supply stepped baffle blocks sized based on the connecting pipe diameter.

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