Firestone EPDM Ballasted System

System Benefits Low installation cost Use of large EPDM panels Fewer seams Fast installation Excellent fire rating Superior weathering resistance Large choice of compatible substrates

System Criteria

The Firestone EPDM Ballasted or Inverted System can be applied on any building that can accommodate the extra load of the ballast and where the roof slope does not exceed 1:6.

System Installation

The RubberGard EPDM sheets are loose laid on the substrate. Adjoining sheets are overlapped a minimum of 100 mm and spliced with Firestone QuickSeam Splice Tape. Roof perimeters and penetrations are flashed in accordance with Firestone specifications (pdf 1.598 kB). Once completed, the EPDM membrane is held in place using approved river washed ballast or smooth paving stones, with a minimum weight of 50 kg/m².

Firestone EPDM Inverted System

The Firestone Inverted System is a variation of the conventional Ballasted System and is ideal for roofs with regular traffic and/or in very severe climates. The EPDM sheets are separated from the ballast by a layer of moisture-resistant insulation boards and a geotextile, loose laid on top of the membrane.
