Composite Geonet for Drainage
Description
Geocomposites are formed by the bonding of two or more geosynthetics to achieve specific physical properties such as added protection, drainage, or filtration. Transnet geocomposite is produced by flame laminating a non-woven 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. It also acts as a flow channel for fluids while the geotextile filters and separates to keep soil particles and waste out. Therefore the critical element for geocomposites is Transmissivity or flow rate.
Functions
· Primary function depends upon final product
· Drainage
· Separation
· Reinforcement
· Filtration
· Liquid Barrier
· Designed for specialty, critical and or permanent applications
Applications
· Numerous and growing
· Cover systems they inhibit the accumulation of pore-water pressure above the barrier layer by providing a high capacity flow path for the drainage of excess liquids
· Component of gas venting system below the barrier layer to prevent gas build up
· Replacement to granular leachate collection system
· Underneath the primary liner as the leak detection layer
Benefits
· Wide range of product combinations- allows for performance driven product selection
· Drainage capabilities are achieved with drainage geocomposites at costs far less than sand and gravel aggregate systems.
· With the filter, drainage and protection layer being a single unit can be installed rapidly at costs lower than conventional aggregate layers
· Chemical resistance provides long life in harsh environments
· Cost effective replacement to granular drainage systems- cost savings on material, transportation, and installation
· Saves time and natural resources- preserves aggregates resources for structural applications where alternative materials can not be used
