Combined Basal Drainage & Membrane Protection
Modern landfill design requires a leachate drainage layer up to 500mm thick at the base of the cell. This fills hard won void space with equally hard won primary drainage aggregate.
Geofabrics LFX composite drainage layer
Geofabrics LFX is a composite drainage layer to be used in conjunction with only half the depth of aggregate whilst maintaining the same leachate extraction performance.
LFX provides numerous benefits to landfill engineering:
Reduces use of expensive and scarce primary aggregate
Void saving to allow more efficient and productive use of space
Reduced haulage of construction materials to site – a single truck of LFX can replace up to 90 trucks of aggregate. It also benefits the client and contractor
Using the composite means much lower material, transport and installation costs
The CQA inspection can be carried out in a factory environment
The drainage core has a proven flow rate and has been tested up to 1000kPA allowing for use in the deepest landfills.
