Use

AQUAZIP BARRIER SYSTEM, in compliance with standard UNI 10686 and subsequent Ministerial Decree. M. 20 August 1999, is intended for the remediation of asbestos-containing structures, using products that fix the fibres, embedding them permanently in a polymer matrix, thus preventing their dispersion into the environment.   The standard applies mainly to asbestos-cement flat or corrugated slabs and other similar products.

AQUAZIP BARRIER SYSTEM is specifically designed for application types A, B and C as defined by the regulations:

TYPE A – VISIBLE ENCAPSULANT FOR EXTERIORS: intended for products containing asbestos that remain exposed to the weather and remain visible after treatment.   Typical applications include: cement-asbestos roofing, external corrugated sheets, external filling panels, asbestos-containing fibre cement facade cladding.   After applying the primer, there must be at least two layers of waterproofing membrane in a different colour must be applied to monitor possible consumption of the individual layers;

TYPE B – EXPOSED ENCAPSULANT FOR INTERIORS: used when the item remains visible and is located in interiors not subject to the weather.   These include applications such as: cement-asbestos false ceilings, interior coatings, industrial premises and warehouses with exposed asbestos products.   After applying the primer, there must be at least two layers of waterproofing membrane in a different colour must be applied to monitor possible consumption of the individual layers;

TYPE C – NON-VISUAL ENCAPSULANT: used when the item being treated is subsequently covered by a false ceiling, wall lining or other containment systems. In this case, after treatment the coating is not accessible or visible.   These include applications such as: technical elements placed in cavities, items incorporated into new stratigraphy, coverings intended for overlaying, panels intended to be confined.   In this case, an encapsulation cycle consisting of a single layer of waterproofing membrane can be certified.   This is not the case for AQUAZIP BARRIER SYSTEM, which involves the application of the two membranes described above.

Product benefits

• The permanent encapsulation work represents an effective and sustainable solution that guarantee long-lasting protection with low operating costs and quick application.   The activity can be carried out without compromising the usability of the building with straightforward application procedures.   The system obtained in this way prevents the generation of contaminated waste, minimising exposure to risks for workers and the environment.
• Specifically for the stratigraphy envisaged by the AQUAZIP BARRIER SYSTEM, the use of AQUAZIP BARRIER PRIMER guarantees effective adhesion of the subsequent waterproofing membrane layers to the cement-asbestos substrate.   The properties of AQUAZIP BARRIER allow it to be applied on horizontal, inclined or vertical surfaces, adapting to surface irregularities.   Once dry, the product’s elasticity makes the system adaptable to any vibrations or sudden changes in temperature.   The use of AQUAZIP BARRIER SRI, with a high solar reflectance index (SRI 107 according to ASTM E 1980-11), as the final layer, helps reduce heating due to direct radiation and maintain a cooler temperature indoors.
• AQUAZIP BARRIER and BARRIER SRI, classified according to the PI-MC-IR principles in accordance with EN 1504-2, are suitable for protecting, controlling humidity and increasing the resistivity of concrete structures.
