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.
