Efflock ideal for building in high saline areas
Read more →I gave a talk about Efflock to local builders at a Master Builders Association meeting out at Campbelltown last week. An interesting problem was raised, which I have touched on briefly in a previous blog. A builder at the meeting told me that the soil in the Camden area south west of Sydney is notorious for high salinity. The high salt content presents major problems for standard construction where rising damp can have very damaging effects on brickwork below the DPC or 'Damp Proof Course' level. The DPC is typically located around floor level, meaning that numerous courses of bricks...

Efflorescence on ABC1's Gardening Australia:
Read more →Efflorescence is such a common building defect around Sydney and Australia. Did anyone else see Gardening Australia last night? Above: Check out the efflorescence coming up out of the grout joints from the tile bed on these balconies just next to Costa Georgiadis as he reported from an apartment complex in Redfern, Sydney. There was a fair bit of efflorescence seeping from render as well during the story. Using Efflock is the very best prevention for efflorescence. So simple and very economical.

Recommended Reading: Salt Attack & Rising Damp in Buildings
Read more →This publication is a great reference for builders and for anyone considering building or renovating - particularly for understanding rising damp in older houses. Salt can be an incredibly destructive compound, and understanding how salt damp behaves is the first step in designing a solution to control and prevent salt attack. Efflock is an ideal product to prevent the transport of salt throughout masonry. Efflock is excellent for use in new construction to prevent efflorescence and damp problems in tiled patios and wet areas, but can be used in many different applications such as render and brick mortar. It can sometimes however,...

Efflock to prevent rising damp and salt attack in buildings
Read more →Photograph showing rising damp and subsequent salt attack below DPC level. Rising damp is destructive for buildings. It is well understood that damp very quickly will create rot in structural timbers such as bearers and joists, and therefore a DPC (damp proof course) is provided to prevent rising damp. A modern DPC is typically a black embossed polythene roll that is laid out directly beneath ant-capping, or just below finished ground floor level. Polyethelene underlay (black or orange plastic) serves the same purpose for slab on ground construction. What is not usually considered, is that rising damp can also have destructive consequences...
