BITEXTENE FLEX/MT SERIES<br />
Product description<br />
BITEXTENE/MT waterproofing membranes are produced by co-extruding a specially formulated elastomeric compound<br />
consisting of a complex dispersion of rubbers and copolymers in selected distilled bitumens with a non-woven continuous<br />
filament stabilized polyester fiber reinforcing mat located midway through the membrane’s thickness and acting in<br />
total synergy with it. The BITEXTENE/MT Series consists of two versions: BITEXTENE FLEX/MT3 and MT4, with thicknesses<br />
of 3 and 4 mm respectively.<br />
Both faces are coated with TEXTENE ® preformed textured polymer fiber film. BITEXTENE FLEX/MT Series membranes<br />
are supplied in strapped rolls, each accompanied by a Quality Control Certificate.<br />
They comply with CE marking requirements where applicable, and contain no asbestos, tar or other dangerous substances.<br />
Recommended uses<br />
BITEXTENE FLEX/MT Series membranes are ideal for all applications calling for excellent bonding to the substrate, as is<br />
needed when waterproofing below-grade walls, vehicular traffic-bearing surfaces, etc.<br />
Compared to ordinary finishes, the TEXTENE ® treatment is cleaner to work with and releases less dust, ensuring low environmental<br />
impact at the installation site. The two textured faces improve membrane torch application, making for faster<br />
installation and more effective adhesion to the substrate.<br />
Membrane suitability for applications where CE marking is required is detailed in the table below.<br />

Methods of application<br />
BITEXTENE FLEX/MT Series membranes are designed for easy torch application after priming, or are secured using<br />
mechanical means. They are also suitable for cold application using ADITHENE adhesive. Waterproofing performance<br />
will depend to a significant extent on application methods. Designed for versatility and ease of application, BITEXTENE<br />
FLEX/MT membranes are laid using standard tools: a propane torch, trowel and cutter. Special care must be taken at<br />
joins, which must be overlapped. Membrane must be laid to allow side laps of 8 to 10 cm and end laps of 12 to 15 cm.<br />
For detailed documentation and guidance in selecting the most appropriate procedures for any job, consult IMPER<br />
ITALIA S.p.A. Technical Services, who will be happy to provide assistance and advice in designing special waterproofing<br />
systems and helping you make the best use of these materials.
