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...

Some basic facts about everyday building materials you may not know.
Read more →It was pointed out to me yesterday, that to date, my blogs are written in a way that assumes some prior technical knowledge about building. Considerable interest about Efflock is coming from home owners, 'Do-It-Yourselfers', or from people who are interested in including Efflock in their building project, but aren't quite sure how to recommend its use or exactly what it does to the tradesmen they are engaging. So here goes.... Firstly, many people may assume that concrete is waterproof: It makes sense right? You see concrete on bridges, footpaths, driveways and balconies everywhere, so surely water doesn't affect it?? ...

Efflock now available at Skippens!
Read more →Skippens is a family business and has been supplying bulk building materials to the Eastern Suburbs and greater Sydney for over 85 years. One of the most common questions they get is "how do I clean off efflorescence?". Unfortunately we don't have a solution for that, other than a cold chisel. However, Efflock will prevent efflorescence in all your future projects! By simply adding Efflock to the water of all your cementitious building materials, you will prevent efflorescence, reduce mould and algae, and prevent water 'wicking' through those materials. Nothing else has to change, you can keep your favourite mixes...

Efflorescence can be avoided
Read more →Before Efflock, methods to control efflorescence required much complexity and have been flawed in one way or another. In fact, Chapter 9 of 2009 edition of the "Master Builders Association Guide to External Waterproofing" lists the the well adopted methods and highlights each of their disadvantages. In summation it concludes "there really is no way to completely prevent efflorescence"- which is incorrect. Efflorescence is something that is not widely thought about, until it begins to deface a building and starts costing money. It has until very recently been considered a maintenance issue, but that is no longer the case. Builders and tilers are being held liable,...
