Precon’s Impact Baffle is an outlet-style structure and it is designed to dissipate energy as water is introduced into a drainage system or natural water course. The dissipation of energy is controlled by a baffle wall that is cast into the structure. The headwall acts as an anchoring system and as a seepage barrier. It is designed to USBR standards and can accommodate flows between 0.4 m3/sec – 5.6 m3/sec, with pipe sizes up to 1350mm in diameter. It comes in 5 sizes and is easy to install.
