In the mining industry there are facilities like heap leach pads and tailing dams which are of great concern if hazardous material stored in them leaks to surface and ground waters. Geosynthetics are used as barrier systems in these applications either alone or together with other more conventional options like clay or asphalt liners. Windavar with experience of installation projects up to 800,000 m², is a reliable partner when considering the use of geosynthetics in these mining process applications. They can also provide solutions to stability problems in haul roads.
