Approved for use on


Balconies, Terraces & Walkways Flat Roofs Green Roofs Inverted Roofs Pitched Roofs Zero Falls Buried Roofs 

For use as a liquid-applied roof waterproofing system on new or existing roofs with limited(1) or pedestrian access(2) in the following specifications:
• exposed warm and cold flat and pitched roofs(1)
• protected warm and cold flat and zero fall roofs (ie covered by pavers or other suitable protection) (1)(2)
• green (extensive) flat, zero fall and pitched roofs(1)(2)
• inverted flat and zero fall roofs(1)(2)
• terraces with anti slip layer (2)
• walkways across roof areas with anti slip layer (2)

(1) Grades approved by the Certificate holder
(2) The advice of the Certificate holder should be consulted on compatibility with the system

Substrate


Concrete Mastic Asphalt Reinforced Bituminous Membranes Single Ply Membranes - EPDM Single Ply Membranes - PVC Single Ply Membranes - TPO Timber 

The system is suitable for use on the following substrates:
• concrete
• asphalt
• plywood(1)
• OSB 3(1)
• reinforced bitumen membranes (including sanded and mineral surfaced felts)
• insulation(1)
• GRP
• single-ply membranes(2)
• previously-coated surfaces(2)
• small areas of metal incidental to the roof, eg pipe upstands
• small areas of plastic-coated metal incidental to the roof(1)

(1) Grades approved by the Certificate holder.
(2) The advice of the Certificate holder should be consulted on compatibility with the system.

Durability


30 Years 

The system will achieve an initial life expectancy of at least 30 years. When fully protected and subjected 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.

Installation Requirements


Installation of the system must be carried out in accordance with the relevant clauses of Liquid Roofing and Waterproofing Association (LRWA) Note 7 – Specifier Guidance for Flat Roof Falls and the Certificate holder’s instructions and this Certificate only by specialist roofing contractors trained and approved by the Certificate holder in accordance with their Installation Manual.

Fire Safety


When tested to DD CEN/TS 1187 : 2012, Test 4, the following flat roof systems achieved a
classification under BS EN 13501-5 : 2016 of BROOF(t4) for roof pitches between 0° and 10° and so are
unrestricted with respect to proximity from a boundary by the documents supporting the national
Building Regulations:
• a flat roof system consisting of primed 18 mm thick orientated strand board, a 0.6 mm thick self-adhesive vapour control layer, a 120 mm thick, foil-faced polyisocyanurate insulation board bonded with a polyurethane adhesive, one coat of Protec Evolve Base Coat Resin at 1.5 ℓ·m-2, a layer of Polymat reinforcement and one coat of Protec Evolve Top Coat Resin at 0.5 ℓ·m-2(1) a flat roof system consisting of primed 18 mm thick orientated strand board, a 0.6 mm thick self-adhesive vapour barrier layer, a 150 mm thick, tissue-faced polyisocyanurate insulation board bonded with a polyurethane adhesive, a 2.0 mm thick self-adhesive carrier membrane, one coat of Protec Evolve Base Coat Resin at 1.5 ℓ·m-2, a layer of Polymat reinforcement and one coat of Protec Evolve Top Coat Resin at 0.5 ℓ·m-2(2)

• a primed 18 mm orientated strand board, a 0.6 mm thick self-adhesive vapour control layer, a 123 mm thick, polyisocyanurate insulation board, including a 3 mm bituminous facing board, bonded with a polyurethane adhesive, one coat of Polyroof Quick Dry Epoxy Primer at 0.10 ℓ∙m–2, one coat of Protec Evolve Base Coat Resin at 1.5 ℓ·m–2, a layer of Polymat reinforcement, one coat of Protec Evolve Base Coat Resin at 0.50 ℓ·m–2, one coat of Protec Evolve Top Coat Resin at 0.50 ℓ m–2 with 0.4 – 0.8 mm quartz sand broadcast at 1.6 kg·m–2 and one layer of graphite grey Low Odour Sealer Coat at 0.20 ℓ·m–2(3).

(1) Fire Test and Classification reports, reference Q100928-1000 and Q100928-1001 respectively, conducted by BRE Global. Report available from the Certificate holder.
(2) Fire Test and Classification reports, references 20410B and 20410B respectively, conducted by Warrington fire. Report available from the Certificate holder.
(3) Fire test and classification reports, references Q100928-1009 and Q100928-1010 respectively, conducted by BRE Global, Report available from the Certificate holder.

A roof incorporating the system will also be unrestricted with respect to proximity from a boundary under the
national Building Regulations in the following circumstances:
• when used in protected or inverted roof specifications including an inorganic covering listed in the Annex of Commission Decision 2000/553/EC,
• irrigated green roofs.

The classification and permissible areas of use of other specifications should be confirmed by reference to the requirements of the documents supporting the national Building Regulations.

In England and Wales, the system, when used in pitches of greater that 70°, excluding upstands,
should not be used on buildings that have a storey at least 18 m above ground level and contain: one or more dwellings, an institution, a room for residential purposes (excluding any room in a hostel, hotel or boarding house), student accommodation, care homes, sheltered housing, hospitals or dormitories in boarding schools.

In Scotland, the system, when used in pitches greater than 70°, excluding upstands, should not be
used on domestic buildings that have a storey more than 11 m above ground level.

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