Containment and control can be achieved either by constructing suitable in-ground barriers or using hydraulic measures. Barrier systems often have to cope with both liquid and gaseous contamination. This Report covers design criteria, theory and practice for the full range of physical barriers. Guidance is given relating to in-ground barriers, multi-layer cover systems and liners, the theoretical basis for these systems and appropriate in-situ and laboratory testing and analysis, for design and performance monitoring. Experience with physical containment is reviewed and presented in terms of the efficacy of these techniques, the need for close quality control over materials and installation and how they may be improved. In general, the Report: * reflects 'good practice' and * is applicable to most contaminated land situations including those which do not conform with the classic 'redevelopment' scenario, such as highways and active industrial sites.
