The new generation polymer-modified APP bituminous waterproofing membrane for roof waterproofing consists of a central non-woven polyester core (180 gsm), impregnated and coated on both sides with a layer of APP (Atactic Polypropylene) polymer-modified bitumen, and finished with heat-fusible polyethene on both surfaces.
Advantages:
- High resistance to positive water & vapour pressure.
- Good dimensional Stability Under tension.
- Good flexibility.
- Can accommodate structural movements.
- High Puncture and fatigue resistance.
- High tensile and tear strengths.
- Resists water-borne chemicals.
- Accommodates structural movements.
Features
- APP (Atactic Polypropylene) Modified Bitumen formulation ensures excellent heat resistance, flexibility, and long-term durability.
- High tensile strength reinforcement (Polyester / Fiberglass) provides superior dimensional stability and resistance to tearing.
- The product’s enhanced UV and weather resistance makes it suitable for Middle Eastern and African climates.
- The torch-applied membrane has strong adhesion, ensuring seamless, fully adhered waterproofing layers.
- Excellent waterproofing performance, creating a continuous, impermeable barrier against water ingress.
- Resistant to ageing, thermal shock, and temperature fluctuations, even under intensive exposure.
- Available in multiple thicknesses (3mm, 4mm) and finishes (Plain, Sanded, Mineral) for various project needs.
- High softening point and low-temperature flexibility, suitable for both hot and cold environments.
- Compatible with concrete, screed, metal, wood, and insulation boards.
Areas of Application
- Roof waterproofing for residential, commercial, and industrial buildings.
- Foundation and substructure waterproofing, protecting against groundwater and soil moisture.
- Basements, retaining walls, and below-grade structures require durable moisture protection.
- Wet areas such as bathrooms, kitchens, balconies, and service rooms.
- Podium slabs, terraces, and planter boxes, where long-term waterproofing is essential.
- Waterproofing for bridges, tunnels, culverts, and other civil engineering structures.
- Car park decks and podium roofs are exposed to constant weather variation.
- Protective membrane layer in multi-layer waterproofing systems, including bituminous coatings and insulation boards.
- Refurbishment of old roofs, providing an additional protective layer over existing waterproofing.
