  When salt attack hurts! - Scarborough Beach, Western Australia.

  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...

  Salinity in Australia - a big problem that builders need to consider.

  The Master Builders Association meeting held in Maitland last week had a very entertaining and informative guest speaker from the NSW Department of Primary Industries. The topic was urban salinity. Salt from the soil can have a very destructive and catastrophic effect on masonry in buildings. Salt is drawn up into masonry with rising damp, and over many years with wet and dry cycles, more and more salt is deposited into the point of evaporation, typically in brickwork or stonework below damp proof course [DPC] level. The pressure exerted by crystallising salt can exceed 200MPa, whilst the tensile resistant strength...
