A blog about Landfill Construction Quality Assurance
European Directives Arguably, the most important European legislation relevant to landfill containment is embodied within the Council Directive of 17 December 1979 on the protection of groundwater against pollution caused by certain dangerous substances (80/68/EEC) (CEC 1979). The Annex to this Directive contains two lists of generic as well as specific compounds or substances. List [...]
The choice of Geosynthetic Clay Liner (GCL) may be a great option when the more normal Compacted Clay Liner (CCL) option is expensive or is not readily available in a region. Read about GCLs here!

However, this very engineering holds dangers for the environment around a landfill, with raised leachate levels, and extra stress on landfill lining membranes.
Leachate drainage layers are necessary in most waste landfill sites to minimise the accumulation of leachate within the site and they reduce the risk of contamination of surrounding ground and groundwater. A cheaper and environmentally preferable option is be the use of scrap vehicle tyres, but is their use permissible and what happens to them [...]
Dense Asphaltic Concrete has been as a Landfill Lining membrane material for many years and although it is not commonly seen in the UK, it is used much more often in Europe, and particularly in Germany. The Dense Asphaltic Concrete is formulated in a manner which ensures both very low permeability and possibly as low as 1 [...]
