APP Bitumenous membrane (waterproofing material)

APP Modified Bitumen Membrane, short for Atactic Polypropylene Membrane, is a special waterproofing material that is manufactured from Bitumen. They come in rolls. Each roll measures 10 meters by 1 meter and covers an area of 8.7 m². With proper workmanship, the APP membrane is a very efficient and durable waterproofing material used in most constructions.

It is a common waterproofing material used on concrete flat roofs (which are still roofs) or roofs with low pitch. Apart from concrete roofs and low-pitched roofs, other areas of application are concrete gutters, basements and retaining walls.

High-performance torch-on waterproofing plastomeric multi-purpose membranes guaranteeing years of use in cold and hot climates.

APP Modified Bitumen Membrane is a superior, high-performance waterproofing membrane, formulated with select bitumen, modified with APP for greater elasticity, flexibility, and further enhanced with a blend of Polypropylene (PP) for high heat resistance (up to 120 degrees), greater elongation and low temperature flexibility (up to –10 degrees). Hence, it is the cause of optimum adhesion and flexibility of modified bitumen.

The main advantages of our APP membranes include:

• Enhanced bitumen performance by increasing UV resistance
• Increasing flexibility at low temps
• Improving flow resistance at high temps
• Excellent weathering
• Fire resistant properties
• Climate adaptability
