Why We Recommend These Products
The Australian climate is extreme, and can put a lot of stress on structures & products. Thermal and differential movement can cause damage to building components. Also, the harsh sun and frequent downpours can take a toll on the waterproofing system protecting the structure.
That’s why it’s important to choose a waterproofing membrane that has been proven effective, of high quality and durable enough to guarantee the moisture integrity of a building. At Projex Group, we only specify waterproofing solutions that have been tried and tested in the Australian climate with a proven track record of 35 years.
The products we specify are versatile enough to be applied to most building materials including concrete, timber, steel, CFC and masonry. They also exhibit the best-designed self-supporting terminations on the market.
These products are also designed to withstand domestic and industrial chemicals and cope with building movement. Both are durable, UV stable and easy to repair.
