Althon Precast Headwall with Diffuser Blocks

September 2018

We can produce when required precast headwalls with diffuser blocks on the spillway of the headwall. Diffuser blocks reduce the velocity of water discharging through the connecting pipework into the watercourse.

The precast headwall shown in the photo has horizontal wingwalls, required due to the bank profile on this particular project. We have also factory fitted galvanised steel Kee KlampĀ® handrail to the back and side walls to for the safety of the passing public.

The headwall is shown being lifted by chains and M20 lifting loops to lifting points cast into the spillway of the headwall.
