The use of rounded 'pebble' coarse aggregates in major civil engineering projects in the Republic is quite unique. When Escom sited Matlmba Power Station in ElIlsras, an area scarce in conventional aggregate materials, the decision was taken to use the rounded colluvial pebbles for concrete aggregate. Both Escom and the contractors' engineering personnel had to become familiar with the very different characteristics of the stone, but combined efforts made the venture technically and commercially successful.
