POLYBOND

DESCRIPTION
POLYBOND is an oxidized bitumen waterproofing membrane suitable for application by gas torch or with hot bitumen,  with a special multi-layered design for superior pliability, tensile strength and  workability. The multi-layered design consists of a polyester core coated on both sides with oxidized bitumen. The polyester core gives the membrane high tensile strength, elongation and superior lap joint strength. Properly installed POLYBOND  forms an impervious waterproofing  blanket which accepts normal structural movement without breaking or cracking.  

USES
POLYBOND   maybe used for wide range of waterproofing applications including roofs, reservoirs, basements, tunnels and car parks. 

OUTSTANDING FEATURES
· Excellent cost performance ratio.
· Good resistance to fatigue and tear.
- Outstanding bondability and seam integrity.                                     
- Impact and puncture resistant.     
- Single layer installation reduces costs.                                                           

 

STANDARDS
POLYBOND complies with the requirements of the  tolerance levels of the following standards:
NF P 84314 Type 40 VV (France)
DIN 52131 V60 S4 (West Germany).

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

APPLICATION
POLYBOND 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.

COVERAGE RATE

For flat areas

                          

                             1.13 M2/M2 per layer

For 30 cm. girth flashing

0.35 M2/Mt/ length

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 reheated 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.

FINISHES
Black finish with thin, heat fusible polyethylene film on both surface.             

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