When it is essential that liquid does not migrate into the tunnel or vice versa – Aquatan is the answer. Our high-quality geomembranes and cuspated drainage membranes have a proven track record.

We have lined major tunnels in South Africa, among them the Drakensberg Scheme Headrace tunnels; the giant machine shafts of the Palmiet Hydro-Electric Scheme and the Huguenot tunnel. On these projects the Geomembrane formed an integral part of the total lining system and Aquatan assisted at the design stage.
