Floodgates - Concrete


Floodgates are adjustable gates used to control water flow in flood barriers, reservoir, river, stream, or levee systems. They may be designed to set spillway crest heights in dams, to adjust flow rates in sluices and canals, or they may be designed to stop water flow entirely as part of a levee or storm surge system. Since most of these devices operate by controlling the water surface elevation being stored or routed, they are also known as crest gates.

In the case of flood bypass systems, floodgates sometimes are also used to lower the water levels in a main river or canal channels by allowing more water to flow into a flood bypass or detention basin when the main river or canal is approaching a flood stage.

Our floodgates are designed to be fitted on to concrete culvert or stormwater pipe, they come with a weighted head wall in sizes from 225mm to 450mm. We have recently developed a floodgate suitable for concrete pipes up to 750mm and have proven to be a cost effective solution to protecting any rural or urban application.
