Approved for use on

Biodiverse Blue Roofs Brown Roofs Flat Roofs Green Roofs Inverted Roofs Pitched Roofs Protected Roofs Zero Falls Buried Roofs 

For use on flat, limited or pedestrian access roofs as a waterproofing layer in:
• inverted roof specifications using aggregate ballast on flat roofs, including zero fall roofs with limited access
• protected inverted roof specifications using pavers or other suitable protection on flat roofs, including zero fall roofs with limited or pedestrian access
• green roof (extensive) specifications on flat roofs, including zero fall roofs with limited or pedestrian access, or pitched roofs with limited access
• roof garden (intensive) specifications on flat roofs, including zero fall roofs with limited or pedestrian access
• blue roof specifications.


Brick Concrete Metal Timber 

The membrane will adhere to concrete, brickwork, blockwork, metal, plywood and timber details. Metal should be free from oil, rust, paint or other coatings liable to affect the bond.


25 Years 

The system will achieve an initial life expectancy of at least 25 years.

When fully protected and subject to normal service conditions in an inverted roof specification with an open covering (eg aggregate pavers), the system can provide an effective barrier to the transmission of liquid water and water vapour for the design life of the roof in which it is incorporated.

However, in situations where maintenance or repair of any of the components in the roof structure are necessary (eg protection layer, insulation), the durability of the membrane may be reduced.

An estimation cannot be given for the life of green roof, brown roof, blue roof or roof garden specifications owing to the nature of use. However, under normal circumstances, it should be significantly greater than for open coverings.

Installation Requirements

The system should only be installed by contractors who have been trained and approved by the Certificate holder.

Fire Safety

The membrane, when used in an inverted roof specification including an inorganic covering listed in the Annex of Commission Decision 2000/553/EC, can be considered to be unrestricted under the national Requirements.

In the opinion of the BBA, when used in irrigated roof gardens, brown roofs or green roofs, the use of the membrane can be unrestricted under the national Building Regulations.

The membrane must always be used under a protective surface finish. The fire rating of the roof is dependent on the finish and the insulation used, the designation of which should be confirmed by: England and Wales — test or assessment in accordance with Approved Document B, Appendix A, Clause 1, Scotland — test to conform to Mandatory Standard 2.8, clause 2.8.1, Northern Ireland — test or assessment by a UKAS-accredited laboratory, or an independent consultant with appropriate experience.

If allowed to dry, the plants used may allow flame spread across the roof. This should be taken into consideration when selecting suitable plants for the roof. Appropriate planting irrigation and/or protection should be applied to ensure the overall fire-rating of the roof is not compromised.
