Project Value


Kusile Ash Dams is located in Middleburg, Mpumalanga, South Africa with Engineering firm Black & Veatch and Eskom as the Employer with GAST as the supplier & installer of all Geosynthetic related elements.

"Geosynthetics has become the standard solution in relation to environmental protection over the last ten years in South Africa, taking guidance from International Standards and the hard work of organisations like the Geosynthetics Interest Group of South Africa (GIGSA). GAST, as one of a handful of entities specialising in this field, is proud to have been involved with such a significant project, assisting Eskom and various other entities in completing such a challenging project."

The Kusile Geosynthetics project, which is entering it’s closing stages, has been seen as one of the largest and most complex geosynthetic projects in the Southern Hemisphere due the it’s volumes and intricacy, providing an environmentally friendly and secure platform for Kusile Ash and Coal over 6ha of geosynthetic solutions.
Over the past four years, GAST has supplied and installed a significant amount of advanced geosynthetic solutions to help minimize the environmental impact of the power station.
Geomembranes, geotextiles and various drainage layers were required to help create a barrier between the environment and Kusile’s multiple ash dumps and dirty dams.

GAST employed over 50 community members during this project and transferred much needed skills in this specialised field. As new legislation calls for geosynthetics in most environmental protection systems, the Kusile Ash Dumps have provided a much needed springboard for future job creation.

Kusile Power Station project, which has been fraught with delays and various other problems, has experienced much-needed impetus as it moves towards operational status, and will be able to function with a minimal environmental impact with GAST Geosynthetic solutions.
