Waterproofing is a method by which a surface or item is made resistant to damage by water. It is the treatment of a surface/item using a combination of materials or systems where an impervious barrier is formed to prevent the passage of water entering or escaping in the presence of hydrostatic pressure. The correct selection, installation and application of the specified waterproof membrane system is absolutely critical. We are able to provide our clients a range of superior waterproofing systems for any specific application. APTC Australia supplies waterproofing membrane to trades allied to the construction industry including liquid and bitumen sheet membranes.
