G.Tex manufactures Geonets by an extrusion method from High Density Polyethylene (HDPE). The overlaying parallel strands that make up the Geonet create flow channels which are useful especially in drainage applications. 


G.Tex Geonets can also be laminated at G.Tex to a nonwoven geotextile layer (either on one side or both sides) to form a Geocomposite product. The properties of both the Geonet core (such as structure, weight, thickness, etc...) and the geotextile (such as permeability, apparent opening size, etc...) can be varied to meet site-specific filtration and transmissivity performance requirements. 


Drainage application benefits:

  • High-volume flow paths

  • Cost-effective replacement for natural resources

  • Lightweight and easy to handle

  • Quick and easy to install

  • Lower haulage, material & installation costs

  • Reduced environmental impact 


Geocomposites are normally used as drainage layers for water, leachate and gas conveyance in landfills as well as numerous other applications. Landfill liner and cover systems always consist of large spatial areas with slopes ranging from almost flat to as high as 30% (18 degrees). Even steeper slopes are encountered but to a much lesser extent. 


The interface-shear strength and the internal adhesion strength (i.e. lamination strength) of drainage Geocomposites are an important consideration for many designs.
