Damp walls, mould, ventilation and drainage should all be addressed before structural problems occur.

Damp Guard Australia specialised in repairing rising damp in existing building structures after testing overseas products and methods practiced in Europe in the mid 70’s. The methods of silicone impregnation to the base of masonry walls were a more cost effective and structurally sounder than the old methods of removal and replacement of a row of bricks or mortar.

These systems of silicone impregnation were also tested by the CSIRO in Highett and reported by the Salt Damp Research Committee in 1978. A ‘Code of Practice’ was later approved by the Housing Industries Association and currently accepted by the Australian Institute of Water Proofing. A copy can be viewed on this site.

Other methods of treating rising damp, such as electro-osmosis, gravity feed and pastes were found wanting as there was no guarantee that full penetration of the water proofing product had created a 100% new damp proof course. To ensure full penetration of products a level of pressure is required to expel excess moisture and filled the masonry with the water proof solution. The pressure injection methods will create a new damp proof course at least 120mm thick. This compares to the original which is only one mortar course thick, or just 12mm, a tenth of the thickness.

In Australia, the buildings are relatively new by world standards and there is usually some form of original damp course installed during initial construction. Most common was sheets of roofing slate, which becomes soft and permeable, and a bitumen /sand mix which had a dark colour. This later mix was often weak and over time failed to be effective. A lot depended on the quality of workmanship at the time of construction. Post 1950, water proofing admixtures became popular but were often mixed weak and again failed over time.
