LFX – Landfill Basal Drainage Composite

LFX is a multilayer composite that replaces half of the granular blanket in a landfill basal drainage system with a factory manufactured geosynthetic that combines the drainage and membrane protection functions into one easy to lay product.

LFX - Landfill Basal Drainage Composite

LFX composite brings numerous environmental benefits to landfill engineering:

LFX composite brings numerous environmental benefits to landfill engineering:

  • Reduced use of expensive and scarce primary aggregate.
  • Void saving to allow more efficient, productive use of space.
  • Reduced haulage of construction materials to site.

It also benefits the client and contractor as:

  • Using the composite means 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 tested up to 1000kPa allowing for use in the deepest of landfills.

Proven Performance

LFX has been in active use for over a decade and has been proven to provide an effective system for leachate management. The use of this system has provided significant savings to landfill operators: working closely with the Environment Agency and leading designers, GEOfabrics has lead the way in innovation in landfill engineering using geosynthetics
