  Trapping moisture with a secondary membrane

  The popular approach to controlling efflorescence on tiled balconies, is to provide a secondary membrane directly beneath the tiles. Another approach is to bond the tile bed directly to the substrate and install a single membrane on top. Both of these methods are popular and can be effective in controlling efflorescence from the tile bed, but there are pit-falls. Firstly, efflorescence is also known to release from tile adhesive and grout, which are both located above the membrane. Secondly, these methods trap all the moisture in the tile bed under an impervious membrane. Moisture in the tile bed concrete mix...

  Save building costs with Efflock

  Secondary membranes to control efflorescence are no longer necessary! Efflock is added to concrete mixes such as tile beds and grout to make them water resistant throughout the entire material. Without water able to enter these materials, efflorescence cannot occur. The labour and time savings are also a huge advantage. Please browse through our website to learn more.

  Save building costs with Efflock

      Secondary membranes to control efflorescence are now obsolete and no longer required. Efflock added to concrete mixes such as tile beds and grout bulk impregnates the entire material to make them water repellant . Without water able to freely penetrate these materials, efflorescence cannot occur. The labour and cost savings are a big advantage, and bad weather is less of a worry with construction times. Tiles can even be wet-bedded using the Efflock system. Efflock is also ideal to mix with tile adhesive and grout which are also known sources of efflorescence. Installing a secondary membrane over tile...

  Efflock test with salt water samples

  We've put Efflock to the test with exactly what you should not do to concrete! Pictured are two samples of 4 sand: 1 cement each made with 140mls of straight sea water from Coogee Bay off the coast of Sydney. They have been cured and placed in a dish of water to test their water repellency. In the foreground is the Efflock sample. Even with salt water in the concrete mix there is clearly no wicking effect! Without water able to dissolve salts and free lime, efflorescence cannot occur.
