Description

Fatrafol 807/V, 810 and 810/V - PVC-P Waterproofing Sheet Membranes are roof waterproofing membranes with polyester reinforcement backing.

Scope

1. Fatrafol 807/V, 810 and 810/V - PVC-P Waterproofing Sheet Membranes have been appraised as roof waterproofing membranes on buildings within the following scope:

• the scope limitations of NZBC Acceptable Solution E2/AS1, Paragraph 1.1; or,
• the scope limitations of NZBC Acceptable Solution E2/AS1, Paragraph 1.1 with regards to building height and floor plan area when subject to specific structural design; and,
• with substrates of plywood or suspended concrete slab; and,
• with minimum falls for roofs of 1:30; and,
• situated in NZS 3604 Wind Zones up to, and including, Extra High.

2. Fatrafol 807/V, 810 and 810/V - PVC-P Waterproofing Sheet Membranes have also been appraised as roof waterproofing membranes on buildings within the following scope:

• subject to specific structural and weathertightness design; and,
• with substrates of plywood, suspended concrete slab or structural steel decking sheets; and,
• situated in specific design wind pressures up to a maximum design differential ultimate limit state (ULS) of 6 kPa; and,
• with the weathertightness design of junctions for each specific structure being the responsibility of the building designer.

3. Roofs waterproofed with Fatrafol 807/V, 810 and 810/V - PVC-P Waterproofing Sheet Membranes must be designed and constructed in accordance with the following limitations:

• nominally flat or pitched roofs constructed to drain water to gutters and drainage outlets complying with the NZBC; and,
• no integral roof gardens and no downpipes directly discharging to the roof.

4. The design and construction of the substrate and movement and control joints is specific to each building, and therefore is the responsibility of the building designer and building contractor and is outside the scope of this Appraisal.

5. The membranes must be installed by Fatra Australia Pty Ltd approved applicators.
