Balcony & Deck Waterproofing in Melbourne

Waterproofing Balconies & Decks In Melbourne

Waterproofing of external wet areas, such as balconies, decks, courtyards and terraces are consistently among the most common recurring problematic areas for both domestic housing and commercial apartment blocks. They are considered a category one (major) building defect among home-owner complaints about defective external wet areas; ranking second highest overall and thus, waterproofing leaking balconies is the need of the hour. By using the qualified waterproofing technicians from Australian Waterproofing Company for deck waterproofing in Melbourne, you can give your project the best chance of a long term waterproofing solution.

We highly recommend that for new external balconies you only use a sheet membrane where possible, especially if it is over a habitable living area. We have repaired, replaced & waterproofed over 600 balconies in Melbourne and surrounding areas. In our years of experience, we have found there has been a common factor to balcony failure. Regardless of applicator or manufacturer, the common dominator was that a liquid membrane was applied for waterproofing leaking balconies in Melbourne. If your waterproofer or tiler cannot install sheet membranes, please give us a call and we can supply and install the best product for your external wet area.

How We Waterproof Balconies

The product we use is 3mm torch on, which is a flexible waterproofing membrane consisting of a mixture of penetration bitumen, modified with Atactic Polypropylene (APP), and reinforced with a layer of non-woven polyester is what we use for balcony waterproofing Melbourne. The underside finishing of the sheet consists of an ultra-thin Polyethylene foil for fast burn and greater adhesion to most sub-straights. The upper surface is finished with a mixture of talcum and sand, this gives a fantastic mechanical finish making it easy to get adhesion for direct sticking tiles or applying a sand and cement screed for creating fall.
