About Drainage Geocomposite
Drainage geocomposite combines a polymer drainage core with geotextile filters: the core provides continuous drainage channels while the fabric admits water but blocks soil and waste fines that would clog the channels.
At only a few millimetres thick it can replace a 300 mm gravel drainage layer, greatly reducing load on the liner below and shortening construction time. Transmissivity must be verified at the design normal stress.

Frequently Asked Questions
Two-rib or three-dimensional?
Three-dimensional cores carry higher normal stress and give higher transmissivity—used for landfill leachate and closure drainage. Two-rib suits lighter road and slope drainage.
Can it replace gravel?
Yes where the design confirms transmissivity at the actual normal stress, long-term anti-clogging performance, and a reliable connection to the collection pipe system.
