Waste management is a demanding environment for geocomposite drainage systems. Besides the standard waste management drainage requirements, the drainage system must be capable of draining aggressive liquids. 

Needle punched Geotextiles are used extensively in landfill construction. The primary application is when used above and below the geomembrane liner as a protection layer preventing damage occurring during stone placement and filling operations.

Typical applications include:

Basal liner protection
Cap liner protection
Settlement lagoon liner protection
Landfill cap drainage
Liner protection
Landfill gas venting
Leak detection
Groundwater control
Contamination isolation
Swales and drainage ditches
Stormwater containment lagoons
Process water channels
Culvert outfalls
Intermittent drainage channels
Dams

Design Considerations:

Embankment slope angle
Length
Hydrology
Drainage
Substrate conditions
Flow
Depth of fill (waste)
Type of fill (waste)
Leachate/gas volumes
Soil conditions
Water table
