MERCURY FC MINERAL Broof(T2)

Request information

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).

The reinforcement consists in a heavy-duty rot-proof spunbond non-woven polyester fabric reinforced with glass fiber affording great elasticity, tensile strength and tear resistance. This is a "composite” reinforcement that combines the excellent mechanical properties of polyester reinforcements with the extraordinary thermo-dimensional stability typical of glass-fiber fabrics.

These combined properties avoid surface shrinkage and guarantee tensile strength, elongation and tear resistance allowing the membranes to absorb high levels of strain caused by structural movements of the underlying building and make it possible to employ mechanical fasteners to increase wind load resistance of the roofing system and withstand pedestrian traffic and static loads.

Different reinforcements, as well as any other custom configuration of the product may be necessary to the Client, are available prior agreement with General Membrane.
