Stormwater Control

Over the last 15 years, Marshalls Civils and Drainage has been at the forefront of stormwater management innovation in the development of flow control chambers and has introduced a wide range of easy to install pre-formed flow control chambers either as one-piece or sectional chambers complete with a pre-formed base, benching, weir wall, split wall or head wall. The chambers can be pre-fitted with hydrobrake flow control through a Hydro-Brake Optimum™, Hydro-Brake®, non-return flap valve, orifice plate or a combination of these.
