are a highly recognized dealer, distributor and supplier of Polymer Modified Waterproofing Membranes (SBS/APP) of high quality to ensure the total satisfaction of customers.APP Membranes
(Properties of Bitumen molecules are enhanced by coating them with APP Polymer like increasing the Softening point, cold flexibility etc)
We offer APP Modified Waterproofing Membranes, which are produced with APP compound. The APP compound is a blend of distilled bitumen, a blend of Polypropylene Polymers and selected Filler. The excellent quality of this compound has the beneficial properties of low cold flexibility and high heat stability. These properties directly influence the aging resistance of the product thus extending the life expectancy of the system. The membranes are highly suitable for most geographical locations and use in high performing insulated roof systems. Because of the compounds excellent heat (stability this membrane is highly suitable for summer conditions or warmer climates. The reinforcement used in these membranes is a heavy weight non-woven spun bond polyester.
Membranes with excellent dimensional stability will check it from failure even in high thermally stressed roofing systems. The reinforcement has high mechanical characteristics ( tensile strength, elongation at tear resistance) which give the following advantages of the membranes.
SBS Membranes (Self adhesive membranes)
- The ability to absorb high stress due to structural movement.
- Excellent tear resistance
- High static indentation resistance which is necessary in roofs gardens and reservoirs.
- High resistance to foot traffic which maintains the aesthetic appearance of the roof.
( SBS polymer is mixed to increase the intermolecular adhesive property of the bitumen.)
SBS Membranes are widely used in the basement for their superior quality and adaptation to take site abuse by their self healing property. It is comparatively expensive membrane compared to APP membrane. Our company never compromise with quality of product and always strive to supply and deals with the best. These products are procured from highly reputed company and is consists of blend of distilled bitumen modified with SBS elastomeric thermoplastic polymers and selected fillers.
The excellent quality of this compound has the beneficial properties of low cold flexibility and Moderate heat stability. Its excellent self healing and high adhesive properties, makes it very suitable. Also these properties directly influence the aging resistance of the product thus extending the life expectancy of the system.
The top surface of SBS membranes are laminated with cross laminated plastic film and also with PVC film. These surface finishes are recommended for specific application. In certain varieties of SBS membranes, in higher thickness uses polyester mat as reinforcement and it also provides excellent dimensional stability to the membranes, which will avoid shrinkage in systems subject to high stress.Application
The membranes should be used to a clean, smooth and dry substrate which has been treated with a fast drying bituminous primer. Application of APP membranes will generally be achieved by heating the underside of the product with a suitable torch appliance with side laps of 10 cm and end laps of minimum 15 cm. SBS self adhesive membranes are laid over a coat of primer with 70mm overlaps. Care should be taken to ensure a perfect seal on the laps. The application of membranes should always be carried out by trained, competent and approved installers. The contractors should always work in accordance with the manufacturer's instructions and specifications.
