In landfill engineering, landfill cells and caps are designed in different ways to maximise containment of potential pollutants and to facilitate gas collection for possible energy production..

Landfill lining systems incorporate a range of geosynthetic products including impermeable membranes, protective geotextiles, and drainage geocomposites, to contain the fluids and contaminants that may leach from the waste as well as direct these fluids to collection points for treatment.

Geosynthetic landfill caps utilise impermeable membranes, and a drainage geocomposite to prevent precipitation from penetrating into the landfill body, minimising the generation of leachate in closed facilities. They also utilise a gas collection membrane to enable safe disposal of waste gas.

Sacrificial daily covers can be used to replace the 150mm (minimum) of inert material used to cover each daily input. These covers help odour control and prevent ingress of rainwater and give a valuable saving in void space.

Intermediate re-usable covers are available for applications where the cover is to be left exposed for a longer period than overnight with the same benefits as the sacrificial daily covers.

Temporary capping membranes are also available with a guaranteed 3 year or 5 year life span.

“Brown field” industrial sites that require remediation may also benefit from the use of geosynthetic sealing systems. By using geosynthetic solutions, industrial sites can be redeveloped for new use at a fraction of the cost of soil treatment and decontamination.
