POLYFLEX DESCRIPTION
BITUMAT POLYFLEX is a uniquely formulated, prefabricated waterproofing membrane with a special multi-layered design for superior pliability, tensile strength, workability and resistance to elements. The multi-layered design consists of a polyester core coated on both sides with APP modified bitumen. The polyester core gives the membrane high tensile strength, elongation and superior lap joint strength.
USES
BITUMAT POLYFLEX membranes are ideal for a wide range of waterproofing applications including roofs, reservoirs, basements, tunnels and car parks. BITUMAT POLYFLEX may be utilized in exposed and covered applications.
OUTSTANDING FEATURES
- Total impermeability for total waterproofing
- Dimensional stability
- Excellent resistance to aging & weathering
- Outstanding bondability & seam integrity
- Very high resistance to impact & puncture
- Stability at high temperatures & flexibility at low temperatures

FINISHES BITUMAT
POLYFLEX is available in two basic finishes:
- Black smooth finish with polythylene surfaces for covered applications.
- • Coloured granule surfacing for exposed applications.
QUALITY CONTROL
In addition to stringent regular tests by BITUMAT laboratory, our products are tested periodically by Independent Laboratories.
STANDARDS
BITUMAT POLYFLEX - complies with the requirements and tolerance levels of :
- The American Society for Testing & Material ASTM-D-6222 Type I.
- UEAtc (European Union of Technical Agreement).
- MOAT 27 - 1983 and MOAT 30 - 1984.
- CGSB (Canadian General Standards Board) 37-GP56M-July 1980.
INSTALLATION TOLLS REQUIRED
- Gas torch
- Knife
- Trowel
- Measuring tape
- Marking string
- Gloves
APPLICATION
BITUMAT POLYFLEX is installed by torch welding method, loose-laid or fully bonded to substrate. When loose-laid, only laps are bonded together. Peripheres and protusions are sealed 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 re-inforcement. 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.
