Geocomposites are formed by bonding two or more geosynthetics to achieve specific physical properties such as added protection, drainage, or filtration.  Not sure if a geocomposite will meet your specifications? Looking for a unique product to solve your drainage problem?  Call us at 609-971-8810 so we can help you select the right materials for your project.

Why use a geocomposite?

  • The filter, drainage and protection layer are a single unit –  can be installed rapidly at a lower cost than conventional aggregate layers
  • Drainage is achieved with drainage geocomposites at costs far less than sand and gravel aggregate systems
  • More cost-effective than granular drainage systems – saves on material, transportation, and installation
  • Performance driven product selection due to wide range of product combinations

Drainage Composite

Drainage composite is produced by flame laminating a nonwoven geotextile on one or both sides of an HDPE biaxial geonet.  The biaxial design of the geonet provides for high flow characteristics in both machine and cross direction.  In addition, it acts as a flow channel for fluids while the geotextile filters and separates to keep soil particles and waste out.  Therefore, the critical design element for geocomposites is transmissivity or flow rate.

Common Applications

  • Landfill cover systems to inhibit accumulation of pore-water pressure above the barrier layer while providing a high capacity flow path for drainage of excess liquids
  • Component of gas venting system below the barrier layer to prevent gas build up
  • Underneath the primary liner as a leak detection layer
  • Interception and conveyance of leachate in landfills


Manufactured by using bonded nonwoven geotextile on one or both sides of an impervious geomembrane, they function together to create a barrier and cushion system.  In reinforcement applications they provide tensile strength as well as increased resistance to puncture, tear, and friction related to sliding.  Heavy weight nonwoven geotextiles act as a drainage media since in plane transmissivity feature can conduct water or leachate away from direct contact with geomembrane.  Call us at 609-971-8810 for more information on the Huesker Canal³® Composite.

Common Applications

  • Canal liners
  • Landfill covers and liners
  • Waste water lagoons

Reinforced Non-Woven Composites

Manufactured using one or more layers of high strength woven in addition to a nonwoven geotextile.  Results in extreme tensile strength as well as puncture resistance.

Common Applications

  • Embankments over soft soils
  • Subgrade reinforcement
  • Asphalt overlay reinforcement
