BIM modelling for ballasted roof systems

With a loose laid system, a suitable ballast layer ensures that the EPDM roof covering is held in place. This type of roof system can only be applied if the entire construction of the building is designed to accept the extra weight of the ballast layer.


RESITRIX® is the only flat roof membrane manufactured using a unique combination of high-quality polymer-modified bitumen and synthetic rubber EPDM. A successful and advantageous combination because thanks to the polymer bitumen layer on the underside, the material can be used over almost any surface. The re-inforced EPDM core ensures a long life expectancy of more than 50 years (SKZ study).

    HERTALAN® EPDM Membranes

    HERTALAN® EPDM systems offer many advantages over traditional flat roofing systems. EPDM is the synthetic variant of a natural rubber type and therefore has unique product properties. This makes EPDM ideally suited for sealing flat and slightly sloping roofs.

    ✓ Proven life expectancy of more than 50 years
    ✓ Suitable for many different types of roof structures
    ✓ Environmentally friendly product
