Headwalls can be used in a number of scenarios. Typically headwalls are used on the outlet of a retention basin to maintain top water level or for a piped discharge point. The apron of the headwall prevents downstream erosion, whilst the up stand retains the earth behind the structure.

Headwalls are designed to prevent the growth of plants around the pipe that may damage or block the flow. Headwalls are often made from precast concrete to ensure durability and long life. Headwalls also include wing walls to direct water flow exiting from the pipe and retain the surrounding earth. All our headwalls can be supplied with an optional trash screen/vermin grate.

Benefits of Headwall Drainage

Headwalls are a low cost solution to prevent the erosion of soil and drainage pipes.
They are built using strong, durable materials so that they last a long time.
They prevent drainage water from damaging the road structure while also providing structural support.
Headwalls direct the flow of water, reducing damaging turbulence and ensuring the efficiency of the pipe.
They act as a marker that indicates a pipe opening, protecting pipes from accidental damage during maintenance.
They help protect pipes from being crushed by the force of the road overhead.
