TORCHBOND

DESCRIPTION
TORCHBOND is prefabricated waterproofing membrane with a special mult-layered design for outstanding pliability, tensile strength and resistance to elements. The multi-layerd design consists of glass fiber core coated on both sides with bitumen. The bitumen is catalytically air blown asphalt. The glasfibre core gives the membrane high tensile strength and dimensional stability. TORCHBOND combines the proven waterproofing quality of bitumen and the sureness and simplicity of torch-on application. Properly installed TORCHBOND form an impervious flexible and waterproof blanket which accepts normal structural movement without breaking or cracking.

USES
BITUMAT TORCHBOND membranes may be used for a 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                                                      
TORCHBOND 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
TORCHBOND 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.
