Check out the photo of these concrete pavers. They are adjacent to the beach shower at Scarborough Beach in Perth. Pavers in the splash zone have been eroded from salt attack, presumably from swimmers rinsing sand and salt from the beach.
I was in Perth to visit local stores and to compete in the Australian Surf Lifesaving Titles, and I made the mistake of walking across these pavers in bare feet! The bits of gravel were particularly uncomfortable.
Efflock is ideal for concrete block and paving manufacturers. Efflock prevents salt attack, as well as efflorescence and algae growth. Best of all, Efflock drastically helps to retain concrete colours.
