Drainage Geocomposite
Draintube

Draintube is a new geocomposite consisting of two laminated layers of non-woven geotextile with perforated corrugated pipe in between. It combines both performance of geotextile filtration and protection characteristics with high drainage, transmissivity and hydrostatic pressure relief capacity. Various grade of geotextile, sizes of pipe and pipe spacing of up to 4 pipes per meter width are available to match discharge requirement.

Applications are to divert groundwater from wall and foundation, to collect bio-gas and to replace traditional granular drainage layer up to 900 mm. It comes in 3.98 m width x 75 m length roll, with connection accessory, and very simple to deploy.
