EPDM WATERPROOFING MEMBRANES - Rollgum One, Top, Geo, Life, Face In, Face Out, Stick

The EPDM waterproofing membranes from Rollgum are manufactured from a terpolymer elastomer widely used for waterproofing due to its excellent performance against atmospheric agents, acids and alkalis, ultraviolet rays, ozone, and more.

The combination of materials that make up the rubber compound is fed into an extruder, which heats the mixture to approximately 85ºC. This allows the material to be molded and stretched using rollers, with pressure adjusted to meet the required width and thickness parameters of the resulting membranes. Subsequently, the membranes undergo a vulcanization process, during which a chemical reaction breaks the double bonds in the material, granting it enhanced resistance and flexibility.

This process enables the material to reach an elastic deformation of over 400%, allowing it to adapt to the shapes and contours of the surface to be waterproofed and to accommodate thermal expansion and contraction movements.
