What is a Perforated Drainage Trough?
Perforated drainage troughs are a precast concrete system providing an efficient trackside or roadside drainage solution for shallow and deep channel applications.
Traditionally used where the risk of siltation from run off is medium to high and a high hydraulic capacity is required.
Why use a Perforated Drainage Trough?
Much easier than perforated pipes to inspect and maintain – simply lift the cover.
A modular system comprising of trough and riser units of varying heights that are selected to match the individual site requirements. Installation using this modular profile is easier and quicker.
Applications include ballasted track, slab track and tunnel installations.
Can be installed with a geotextile filter membrane if required.
Can be used for track bed protection / sealing applications.
Suitable for pedestrian loading only.
