The PURTOP range is a series of continuous, one/ two-component, polyurea-based membranes without solvents, suitable for application on various types of substrate.
Membranes from the PURTOP range are formed by means of a highly reactive, solvent-free chemical reaction. This reaction ensures that, once the two components come into contact with the substrate, they create a waterproofing membrane in just a few seconds.
PURTOP membranes set to foot traffic and become waterproof immediately and, within a concise space of time, they develop their full performance characteristics.
Exceptional mechanical properties, elongation at failure of more than 300% and excellent resistance to aggressive agents are just some of the certified characteristics of this product. PURTOP membranes also carry CE marking as being compliant with EN 1504-2 (“Concrete surface protection systems”).
PURTOP membranes are the result of research work carried out in the Mapei R&D laboratories and are manufactured in the Mapei facilities around the world in compliance with the most stringent safety standards and the most strict testing protocols regarding environmental sustainability.
It is a well-known fact that, in urban areas, the local temperature rises due to the high density of buildings and traffic and the fewer or total lack of green areas, parks and open spaces helping mitigate this phenomenon. The technological solution to counteract this phenomenon is based on two types of roof:
- green roof > garden roofs that help mitigate the effect of atmospheric pollution while, at the same time, improving the overall appearance of buildings and providing a more pleasant landscape;
- cool roof > flat roofs with special high reflectance and high emissivity finishes which, apart from improving the level of comfort inside buildings, help reduce the temperature of the surface of the roof.
Membranes from the PURTOP range may be used to great effect on both types of roof, as they are certified as being resistant to root penetration (in compliance with the European Standard CEN/TS 14416).
