Tenax SD geocomposites with two strands are an effective and inexpensive solution for drainage of landfills, roads, railways and large areas.
The diamond HDPE structure can be factory laminated with one or two separation and filtration geotextiles creating a filtration-drainage-protection system that is compact and easy to install.
Tenax SD geocomposites can be laminated below with an impermeable light geomembrane (SDcu) to integrate the underlying waterproofing. In case of barriers of compacted clay or GCL (Geosynthetic Clay Liner), it helps maintaining a correct level of humidity and keeping the characteristics of materials over time.
There are various types of Tenax SD drainage geocomposites, which differ in flow rate and lamination with one or two geotextiles (SD-1 or SD-2)
SDcu is obtained by laminating a geotextile above and a light impermeable geomembrane below.
