MERCURY are a range of bituminous waterproofing membranes featuring very good low temperature flexibility and dimensional stability. Due to the compound employed surface protection is advised if employed as upper layer.
MERCURY membranes employ a compound consisting of distilled bitumen modified with high a content of thermoplastic elastomers of the styrene-butadiene-styrene family (SBS) and their excellent quality is mainly highlighted by two indicators: cold flexibility (-20° C) and elasticity.
These two parameters positively affect both resistance to thermal ageing and resistance to cracking of the waterproofing surface, increasing the service life of the roofing system. Thanks to their high resistance to cracking MERCURY membranes are suitable for any climatic zone and for roof systems subjected to significant strains. The excellent cold flexibility guarantees ease of application, an important feature in areas characterized by harsh climates.
Since this compound can be damaged by exposure to UV, it’s suggested to either apply mineral-protected finish MERCURY - or other UV resistant membranes - as upper layer or to use MERCURY membranes under ballast (concrete or gravel-covered pavement).
MERCURY membranes are available with different reinforcements:
- Rot-proof non-woven spun-bond or staple polyester fabric stabilized with fiberglass. These “composite” reinforcements combine the excellent mechanical properties of polyester reinforcements with the extraordinary thermo-dimensional stability typical of glass-fiber and guarantee high levels of performance to the membranes.
- Rot-proof stabilized fiberglass reinforcements offering excellent dimensional stability and avoid unsightly wrinkling of the membranes and shrinkage of the waterproofing surface.
