Bitumat Events: POLYFLAME - APP Modified Waterproofing Membrane

POLYFLAME DESCRIPTION

BITUMAT POLYFLAME is a superior, high performance, prefabricated, modified bitumen membrane consisting of proprietary waterproofing compound, reinforced with spun bonded non-woven polyester mat.

The BITUMAT proprietary waterproofing compound is formulated with select bitumen modified with Attactic Polypropylene (APP) for greater elasticity, flexibility, and further enhanced with a blend of Thermoplastic Polymer (TP) and Elastoplastic Copolymer (EPC) for high heat resistance, greater elongation and low temperature flexibility. The compound is then stabilized with opaque Mineral Stabilizers (MS) for impact resistance, UV resistance and durability.

The superior waterproofing compound is reinforced with a robust, isotropic, spunbonded, non-woven polyester mat for increased strength, toughness and dimensional stability.

The proprietary compound, the unique reinforcement, combined with the famous BITUMAT process technology and rigid quality assurance procedures, yield the most reliable and dependable waterproofing membrane.

POLYFLAME USES

BITUMAT POLYFLAME is a universal, all purpose membrane, excellent in a single layer or multi-layer roofing systems, underground waterproofing, multi-story car parks, pond lining, irrigation canals lining, swimming pools or any structure that requires high performance waterproofing.

FINISHES

BITUMAT POLYFLAME is available in three basic finishes:

Black smooth finish with polyethylene surfaces for covered applications.
Granule surfacing for exposed applications.
Fine sanded upper surface for coated systems.

QUALITY CONTROL

In addition to stringent regular tests by BITUMAT laboratory, our products are tested periodically by Independent Laboratories.

STANDARDS

BITUMAT POLYFLAME complies with the performance requirements and tolerance levels of the listed standards. Some of which modified to better suit the various climatic conditions around the world.

American Society for Testing and Materials, ASTM-D-6222 Type II.
European Union of Technical Agreement (UEAtc)
Canadian General Standard Board (CGSB 37-GP 56M - July 1980).
German Standard DIN 52133.

INSTALLATION TOOLS REQUIRED

Gas torch
Knife
Trowel
Measuring tape
Marking string
Gloves

APPLICATION

BITUMAT POLYFLAME is installed by torch welding method, loose-laid or fully bonded to substrate. When loose-laid, only overlaps are bonded together. Peripheres, protrusions and other flashing details are installed according to specifications.

COVERAGE RATE (Approx.)

(Rate may vary as per site requirement)
Flat areas: 1.15 M2/M2 per layer with 10 cm. side laps and 15 cm. end laps.
Base flashing: 100x35 cm. with 15 cm. end laps, 0.40 M2/ linear Mtr.
Average wastage: 3 - 5 %

TORCHING GUIDELINES

The underside of the membrane should be torched just enough to superficially melt the bitumen. Excessive heating may damage the reinforcement. Overlaps should be re-heated from the top and resealed with a trowel to ensure seam integrity.
For details of installation methods and flashing requirements, consult the relevant BITUMAT Systems Design and Installation Manual.
