High quality polymer concrete and plastic channel drainage systems are available to give you an economical solution to surface water drainage removal.
The channel system is supplied with multiple width and depth options and with a constant level invert or built-in fall to aid in carrying away surface water. A stepped system for increased hydraulic performance can be used to create a channel system with a fall.
Generally the channels come with a galvanised protective edge, although channels are also available with a stainless steel edge should a stainless steel grating be required.
Gratings of varying materials such as composite or ductile iron are also supplied with locking features or with a discreet slot galvanised or stainless steel grating for an easier block paving installation and pleasant aesthetic finish.
Sump units, outlet end caps and other accessories are available to help provide a complete channel drain system.
As well as the polymer concrete channels an alternative option is an interlocking polypropylene heavy duty channel system with ductile iron D400 and F900 gratings.
