What Is Geo-Textile Underlay & How Is It Used In Relation To Flat Roofing?

The Geotextile fleece membrane can be used in a number of ways:

1. The Geotextile can be used on top of the rubber membrane to protect it from sharp objects when it is planned to ballast (cover) the membrane with pebbles for fire protection.
2. Where a cement screed is being installed on top of the rubber membrane to provide a hard-wearing surface for slabs or tiles the geotextile can be placed on top of the EPDM to protect it from sharps in the screed.
3. Install the Geotextile fleece directly over the current roofing substrate to help protect the new rubber membrane from any sharps that could puncture the membrane. In this scenario, the rubber membrane cannot be glued in place so it is either secured using Russ strips (A Grid of mechanically fixed bonding strips) or ballasted in position with pebbles or a green roof. This method is only applicable to ClassicBond.
