The bituminous LARIX SELF-ADHESIVE membranes are the arrival point of the latest generation of membranes denominated “composite”. These membranes are so defined because thanks to new manufacturing technologies it is possible to produce materials with differentiated waterproofing mass, which allow the optimal utilization of each components properties, satisfying the different requirements. The production process avails itself of three different compound types, manufactured in separate dissolvers and sent to the respective areas of application on the production line. The first session allows the impregnation of the reinforcement which is a continuous single strand polyester using a particular compound suitable in saturating all its porosities, providing compatibility and promoting the elasticity or plasticity properties of the different applied compounds be they on the top or bottom surface. During the second session a different compound is applied on the top surface depending on the destination of use of the membrane. During the third session a particular compound with excellent self adhesive properties is applied on the lower surface, the thickness of which is calibrated.

The LARIX SELF-ADHESIVE membranes are capable of resolving specific application and functional requirements and present numerous and important advantages, such as ease of application with consequential savings on time and the possibility to apply the material on surfaces which are not suitable to open flame. Therefore LARIX SELF-ADHESIVE is insuperable in the waterproofing of wood structures, insulation panels which are heat sensitive, panel decks and refurbishment of historical roofs. Furthermore LARIX SELF-ADHESIVE can be used and allows the waterproofing of particular roof details (ex. bandaging of plastic tubes, etc.) and the possibility to also apply with the traditional application method ofopen flame or hot air, obtaining an exceptional level of adhesion.

LARIX SELF-ADHESIVE guarantees a perfect level of adhesion to the application surface, providing the system with an excellent level of wind uplift resistance and allowing accidental infiltrations to be traced. LARIX SELF-ADHESIVE has a continuous single strand composite woven non woven polyester reinforcement with high mechanical characteristics. The lower face of LARIX SELF-ADHESIVE is protected with a removable silicon release film. The upper face is protected with sand.

Fields of use

LARIX SELF-ADHESIVE with its innovative characteristics is indicated to waterproof a wide range of works, both civil and industrial. LARIX SELFADHESIVE shows its peculiarity in those applications where it is not suggestible to use open flame, for example on heat sensitive insulation panels (polystyrene), wooden roofs, metal decks and for all under roof shingle applications.

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.
