Althon manufacture concrete headwalls with precast dissipation blocks on the spillway. We factory fit the dissipation blocks to our precast headwalls ensuring they fit properly every time and reducing installation time on site. Dissipation blocks slow down the flow of water discharging from the pipe across the spillway of the headwall before entering the watercourse.
We can fit dissipation blocks to the spillway of a headwall in any arrangement required, space permitting.
You can use our Headwall Specifier to find the headwall you require. On request we can the provide pricing and design drawings for your chosen headwall with dissipation blocks.
