APP Waterproofing Membrane application & Characteristics
APP uses polyester reinforcement or fiberglass reinforcement as the original source, and APP, APAO, as the modifier, and covers the insulation materials as polyethylene, sands, or gravels. A.P.P. Atactic polypropylene elastomeric type modified membrane is a specially formulated bituminous compound of modified distilled asphalt with selected high-grade visco-elastic polymer and reinforced with the high-quality non-woven polyester conductor.
An APP Waterproofing Membrane is coated with either a sanded or talc top surface finish, while the bottom surface is embossed and protected by a heat-sensitive polythene film. This type of finish for the lower surface has been chosen for two specific purposes.
General-purpose APP waterproofing membrane designed and manufactured for the specific requirements of roofing contractors. The elastomeric modified bitumen polymer (BPP) which is used gives excellent flexibility and workability on any roof. The carrier is a non-woven reinforced polyester giving excellent performance in terms of mechanical resistance. The high dimensional stability is obtained by the insertion of a glass fiber reinforcement inside the polyester itself.
Characteristics for APP waterproofing membrane
• Fine Anti-Water Pressure And Anti-Leakage Property With Water Tightness / Impermeability Effect; Good Tearing Resistance, Puncture Resistance, Weather-Ability, Mold Resistance, Fatigue Resistance, Aging Resistance Property; No Dripping, No Flowing Under Hot Temperature; No Crack Under Cold Temperature With Tight Overlaps/Edges/Ends, No Pollution/Contamination And Environmentally Friendly.
• With high tensile strength, good growth, and self-healing properties to adapt to tight contraction/expansion as well as deformed/cracked substrates, SBS curtains are widely used in waterproof works Of Cold Regions And The Substrates Which Easily Deformed; Whereas APP Waterproofing Membranes Are Widely Used In The Waterproof Works Of High Temperature And Strong Sunshine Regions. It can be easy to work all year round, prevents heat melting Easy work.

• Underpass
• Bridges & Tunnels
• Roof Gardens
• Underground Car Parks
• Medium to large roof slabs
