Installed 13 years ago at Sasol's Shondoni coal mine near Secunda - and not a block out of place!
When the project engineers specified Terraforce Retaining Walls® in 2012, the challenge was clear: coal dust eliminates any possibility of plant growth, making conventional open-gap retaining walls a long-term liability. The Terraforce® closed-face system was the only logical solution - no gaps, no soil loss, no compromise.
Geofabric reinforced fill for high structures, as well as gravity cut face wall designs for lower wall heights, were submitted, accepted and constructed. The highest walls - at a 70° angle - are situated at the main conveyor feeders to the coal bunkers. In total, 2185m² of Terraforce® L11 blocks were installed.
