We have been working with homeowners with rising damp issues in Sydney for over 20 years. The most effective method for the treatment of rising damp is installing a chemical damp proof course (DPC). This process is quicker, less costly and intrusive than alternative methods. Other methods often involve removing large sections of brickwork and wall coverings to get to the interior of the walls.
We use products from techdry which include a chemical damp proof cream (silicon-based). This is installed into the mortar and a salt retarder which is used in the render mix. On face bricks with no render, we can also provide salt extraction which involves using the Westox Cocoon System.
Each job is different and we treat them that way. There are variables such as: blocked cavities and higher external ground levels. In all cases, we inspect the cavities using digital cameras to ensure that our DPC installation will not be “bridged out” by a blocked cavity. If there is higher ground on the opposite side of the wall we will then need to implement negative waterproofing membranes.
