POLYGLAS

USES
POLYGLAS with its unique  combination of properties is ideal for use in heavy duty applications such as bridge waterproofing, tunnels, tanking..etc. In fact, anywhere above and below ground where toughness, impact resistance and dimensional stability are required.

OUTSTANDING FEATURES
· Dimensional stability.
· Puncture resistance.
- Robustness.
- Increased resistance to hydraulic pressure.  

GENERAL DATA 

DESCRIPTION
POLYGLAS is a range of modified bitumen membranes which incorporates a special double reinforcement of non woven, spun bond polyester fabric and  a glass fiber mat. This multi-layer construction is positioned within the mass of modified APP bitumen coating. The finished product is a general purpose, high performance waterproofing membrane with added qualities of dimensional stability and robustness. 

STANDARDS
POLYGLAS complies with the requirements and tolerance levels of :
1. The American Society For Testing & Material, ASTM D-6223 Type I or Type II*.
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
POLYGLAS 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 GUIDELINE
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.                         
 * On request product is available to meet the requirements.

Reinforcement

180 gsm nonwoven polyester fabric & 50 gsm of glasfiber matt. Other weights available on request.

FINISHES
POLYGLAS is available in two basic finishes:
- Black smooth finish with polyethylene  surfaces for covered pplications.
- 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.
