Characteristics
ANTI-ROOT is a prefabricated membrane based on a particular bituminous compound reinforced with non-woven spunbond polyester filaments. The waterproofing compound obtained through the complete homogenization of bitumen distillate with saturated elastomeric and plastomeric polymers is added with “Preventol B2” by Bayer, a synthetic product made with phenoxylate fatty acid polyglycol ester.

It offers:

• resistance to U.V. radiation
• resistance to temperature change
• resistance to O3
• resistance to chemical corrosion (acids and salts)
• waterproof seal
• good adhesion when heated to all supports
• resistance to creep
• resistance to the chemical and mechanical action of roots

Reinforcement

Composed of non-woven spunbond polyester filaments offers:

• high mechanical characteristics
• imputrescibility, elasticity and flexibility
• good isotropy
• resistance to attack by chemical and bacterial agents.

Methods of application

• The membrane is usually applied by heating the bituminous blend using a gas burner or hot air guns in special cases.
• Always use the individual protection devices specified by law.
• Never use these systems on heat-sensitive supports or insulation.
• Scrupulously respect the recommendations and warnings for use provided on the product’s technical data sheet.
• The waterproofing system and the products recommended can be modified as required by the roof’s constructive type and size (please consult our Technical Assistance Service).
• Conduct regular maintenance on the roof in order to remove detritus, mud, grass, etc., and to keep the operation of the waterproofing system and accessories (drains, TV antennas, air-conditioning systems, etc.) under control.
• Whenever there is reason to believe that the element to be waterproofed has traces of residual humidity (e.g. during renovations of existing roof coverings, applications after abundant rainfall), vents should be positioned in such way as to permit its elimination.

Finishing

The upperside of ANTI-ROOT is finished with a special inorganic and extremely fine release material which is uniformly spread and calibrated in order to prevent the roll from sticking to itself providing anti-slip features for applications on sloping surfaces.

The ideal melting point of the waterproofing compound is visible anytime from the burn-off printed and embossed polyethylene surface film which protects the underside. This also allows for vapor diffusion control thus preventing the formation of blisters whenever the membrane is laid with semi-adherence or independently.
