APP Waterproofing Membrane - FAQs

An A.P.P Waterproofing Membrane is a special waterproofing material made from Bitumen commonly used on concrete flat roofs or roofs with a low pitch.

APP Waterproofing Membranes are packaged in rolls. Each roll weighs between 30kg to 50kg, measures 10 meters by 1 meter and covers an average area of 8.7 m² (considering that they overlap). Their thickness ranges between 3mm and 5mm. They can either be plain which means they have no granule coating or with granules which means they have a mineral finish.

APP Waterproofing Membranes are used for waterproofing of low sloped roofs, (also commonly referred to as flat roofs), basements, retaining walls, and concrete gutters.

No, the APP waterproofing membranes covered roofs are not trafficable. Should you need to have heavy traffic on these roofs, then they should be covered with interlocking tiles.

Unlike the APP waterproofing membranes, most liquid waterproofing chemicals do not perform well when exposed to direct sunlight. Liquid waterproofing chemicals are therefore mostly recommended for internal use such as bathrooms and kitchen areas that will not be exposed to the harsh UV Rays.
