The Althon High Capacity Channel Drainage System is a glass reinforced concrete (GRC) channel drainage system available in a range of widths from 150mm to 600mm. We offer a selection of lid units for use in residential, car park through to heavy industrial drainage applications.

The high capacity of the drainage channels enables the installation of long uninterrupted runs without the need for intermediate outfalls. Althon High Capacity Channel Drainage offers considerable reductions in the amount of secondary pipework required. This extra capacity is useful for water storage, the largest drainage channel having a capacity of 412 litres per metre.

The unique trapezoidal shape of the high capacity drainage channel means that water in the channel generates its own flow. Our drainage channel is therefore self-cleansing and can be laid over long lengths without fall.
