The Fatra fully adhered green roof system incorporates Fatrafol 807v PVC waterproofing system bonded directly to the existing failed membrane 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 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.
The Fatra Armour protection mat is installed directly over the PVC membrane to provide protection to the waterproofing system from any sharp edges and pertruding items which might be present in the green roof overlaying finishes
The Fatrafol 807v has a fleece backing which enables the PVC membrane to be fully adhered directly over the existing failed membrane.
The Fatrabond 1215 moisture curing polyurethane adhesive is used to bond the Fatrafol 807v PVC membrane directly to the existing membrane. The Fatrabond adhesive is unaffected by the substrate moisture or inclement weather improving productivity and reducing overall installation programmes.
