Impact Baffle
Precon’s Impact Baffle structure is an outlet-style structure, with an engineered basin and headwall, that 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 and can handle flows up to 3 cubic metres per second. The headwall is also constructed with a unique anchoring system which also acts as a seepage barrier.
The Impact Baffle is easy to handle and install. It is designed to USBR standards and Precon can accommodate many different flanges or pipes, which can be cast directly into the structure. A metal grating is also available.
