End Treatments
Heidelberg Materials manufactures headwalls and flared ends for various end treatments, catering to different pipe sizes and sewer lines. These precast structures seamlessly connect to concrete pipes, serving as inlets and outlets for stormwater ponds, culverts under roadways, and approaches.
Flared Ends:
Flared ends connect to concrete pipe as inlets and outlets for storm water ponds and culverts under roadways and approaches. They come in a range of sizes for 300mm–1500mm concrete pipe and have sloped ends. For larger pipe sizes of 1650mm–2100mm pipe, a concrete box bevel with a cast in pipe adaptor is available.
Round grates are also available with and without a gate for pipe and flared ends. Round grates help to keep animals out and prevent debris from entering the storm system.
