Inferior geo-composite membranes which should both provide a low permeability membrane to cap a landfill and replace drainage stone otherwise needed above the low permeability layer are being offered which don’t do the job. It is essential to drain the interface and prevent development of a slip plane at the membrane on even quite gentle landfill slopes, but slip failures are inevitable if inadequate geo-composites are used. Find out how to avoid this pitfall.

Landfill engineers are increasingly preoccupied with building landfills which will capture as much landfill gas as possible and use that gas optimally to generate renewable energy. However, this very engineering holds dangers for the environment around a landfill, with raised leachate levels, and extra stress on landfill lining membranes.

Landfills nowadays each contain huge amounts of organic materials and hold a huge potential to pollute the local groundwater for generations in the containment systems upon which their design is based fail to function as intended. The engineering of a landfill is no different to other engineered structures, in fact in many ways, especially due [...]

One of the most common locations for landfills are worked out quarries and quarries suitable for landfill are an increasingly valuable resource for this reason. In a growing number of cases suitable sites include rare geological exposures of mineral bearing rock, or strata of regional importance which need to be kept exposed after landfilling for [...]
