Project: Lining of run-off canal
Liner Specification: 2,0mm HDPE
Size: 3 900m²
Contractor: Fraser Alexander Construction (Pty) Ltd
The trapezoidal canal running near the Brakspruit Shaft on the Marikana Mine required lining to prevent seepage from the canal entering the shaft area.
A 2,0mm thick HDPE geomembrane was used as the primary liner. This was then covered with a heavy duty geotextile. This geotextile was used as a protection layer for the installation of the ArmorFlex concrete blocks. The canal is 350 meters in length and provides a watertight and durable canal at the mine.
