POLYFLEX

DESCRIPTION
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 modified bitumen. The polyester core gives the membrane high tensile strength, elongation and superior lap joint strength.

USES
POLYFLEX membranes are ideal for a wide range of waterproofing applications including roofs, reservoirs, basements, tunnels and car parks. POLYFLEX may be utilized in exposed and covered applications.

OUTSTANDING FEATURES
· Dimensional impermiability
· Excellent resistance to aging & weathering
- Outstanding bond ability & seam integrity.
- Very high resistance to impact & puncture.

Roll length	10 mt.
Roll width	1 mt.
Thickness	3, 4, 5, mm
Reinforcement	Nonwoven polyester fabric. .

FINISHES
POLYFLEX is available in two basic finishes:
- Black smooth finish with polyethylene surfaces for covered pplications.
- Coloured granule surfacing for exposed applications.

QUALITY CONTROL
In addition to stringent regular tests by BITUMAT laboratory, our products are tested periodically by Bureau Veritas, SOCOTEC, Paris, France.

STANDARDS
POLYFLEX complies with the requirements and tolerance levels of :
1. The American Societty For Testing & Material ASTM D-6222 Type I
2.UEAtc (European Union of Technical Agreement).
3.MOAT 27-1983 and MOAT 30-1984.
4 .CGSB (Canadian General Standards Board) 37-GP56M-July 1980. .

INSTALLATION TOOLS REQUIRED
Gas torch, Knife, Trowel, Measuring tape, Marking string, Gloves.

APPLICATION
POLYFLEX is installed by torch welding method, loose-laid or fully bonded to substrate. When loose-laid, only laps are bonded together. Peripheries and protrusions are sealed according to specifications.

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 Design and Installation Manual.
