The Fatra fully adhered green roof system incorporates Fatrafol 807v PVC waterproofing system bonded directly to the substrate using the Fatrabond moisture curing adhesive with the Fatra Armour protection layer, Fatra drainage cell, filter fabric and vegetation layer to create the perfect fully adhered green roof system.
The specifications for the different layers will depend on the clients objectives, requirements and project-specific specifications. Fatra provide all components for the green roof projects making it simple and convenient for our approved contractors.
The Fatrafol PVC membranes are tested to FLL standards and are proven to withstand root penetration from the most aggressive roots such as birch and oak trees. No additional protection layers or root resistant coatings are required unlike traditional bitumen and liquid membranes.
Fatrafol membranes are 100% recyclable and can be made using up to 30% recycled materials making Fatra waterproofing membranes the most sustainable and environmentally friendly waterproofing membranes on the market today.
Fatra Armour protection mat is loose laid over the Fatrafol PVC Membrane to protect the membrane from the drainage cell. Installation of Fatra Drainage cell is then installed with a filter fabric applied above the drainage cell prior to the installation of the green roof build up.
The Fatrafol 807v has a 120gsm fleece backing which enables the PVC membrane to be fully adhered directly to the substrate without any primers or extensive preparation.
The Fatrabond 1215 moisture curing polyurethane adhesive is used to bond the Fatrafol 807v PVC membrane directly to the substrate. The Fatrabond 1215 adhesive is unaffected by substrate moisture and inclement weather improving installation programme and productivity.
