SOLUTIONS FOR ACCESS TO ENABLE CAPPING OF TAILINGS DAMS AND OPEN PITS

The first challenge in remediation of mine waste storages is often based around access to the site to construct the capping layer. Geofabrics has design strategies that enable the use of TenCate Mirafi® High Strength Geotextiles or Tensar^® Geogrids to enable cap access and create a bearing capacity that can be trafficked with construction plant. Unlike civil engineering solutions, the liquor chemistry must be considered in terms of Geosynthetic performance, as stress-strain behaviour will change if the polymer is impacted by acid or high pH environments.
