Geocomposites

Landfill & Contaminated Land

Isolation of wastes and the associated collection of leachate and landfill gas have led to a significant use of geosynthetics, not least because of the increasing costs and thickness of mineral layers.

Geosynthetics are not only easier to install but provide a more consistent, quality solution and they can be engineered to provide the appropriate in-service properties.

Protexia geocomposites for the containment of contaminated land are the natural evolution of the technology.
