Final Cover Systems in Landfill
The standard components within a final cover system
- An erosion control layer (top soil)
- A protection layer
- A drainage layer
- A barrier layer
- A gas venting layer
- A foundation layer
Design practices vary from site to site and as a result of national regulation and local conditions. State of the art design in landfill engineering has evolved from the use of natural soils to factory manufactured geosynthetics which allow for improvements in safety, reduced environmental impact and economic savings.
GEOfabrics offer geotextile and geocomposite solutions used in the following areas:
HPS geotextiles can provide essential membrane protection and provide a durable trusted solution to designers.
Combined protection and drainage can be achieved using GEOfabrics GPT composites, manufactured from 100% prime grade virgin polymer offering proven durability.
GPT composites can be installed below a capping membrane to provide an effective pathway for control and extraction of landfill gasses.
