- Podium decks.
- Balconies with pedestrian access.
- Walkways.
Suitable substrates:
- Concrete.

Description
ParaFlex FD is a three component unsaturated polyester resin waterproofing system reinforced with a polyester fleece reinforcement that determines the breaking strength and elongation at break and provides for even layer thickness.
Features and benefits:
- With the correct primers, ParaFlex FD adheres to almost any substrate and the attachments are made permanently waterproof.
- Combination with most bitumen and plastic roof sealing sheeting is also excellent.
- BBA certified.
- Resistant to roots in conformity with DIN EN 13948 (FLL guidelines).
- Resistant to spreading fire and radiant heat, as specified in DIN 4102-7.
- Fireproof as defined by BS 476-3, 2004.
- Durability: Exposed applications should achieve an initial life expectancy of at least 35 years. When fully protected and subject to normal service conditions in an inverted roof specification with an open covering (e.g. 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.
- Properties in relation to fire, buried applications: when used with one of the surface finishes detailed in Part iii of Table A5 of Appendix A of Approved Document B of the Building Regulations (England and Wales) or Technical Booklet E, Table 4.6, Part iv of the Building Regulations (Northern Ireland), would be deemed to be of designation AA.
- Resistance to wind uplift: The system will resist the effects of any likely wind suction acting on the roof.
- Resistance to foot traffic: The system can accept, without damage, the limited foot traffic and light concentrated loads associated with installation and maintenance operations. However, reasonable care should be taken to avoid puncture by sharp objects or concentrated loads. For areas of pedestrian access such as balconies and walkways, an anti-slip finish is applied.
- Curing time: With hardener and accelerator: Rainproof after 20 minutes. Walkable after 30 minutes.

Preparation | |
Horizontal work | EshaFlex SA Primer.Guidance for specification option: A solvent based cold applied bituminous primer for use with Esha SA roofing felts and Esha Universal SA on metal, concrete, stone or timber. EshaPrimer.Guidance for specification option: A quick drying black bitumen priming solution designed to penetrate and seal a variety of porous surfaces including masonry, concrete, cementitious screed/renders, existing bituminous waterproofing and structural steelwork. EshaPrimer creates a base seal and improves the adhesion of bituminous waterproofing solutions. Red Primer.Guidance for specification option: Designed for use with self adhesive SBS modified bitumen roofing membranes and is intended for use on concrete and various porous substrates to aid initial and long term adhesion of the membrane particularly when application is taking place at the lower end of the temperature range (+5°C) for these membranes. |
Skirtings and vertical work | EshaFlex SA Primer.EshaPrimer.Red Primer. |
Air and vapour control layer | AluBase XL.Guidance for specification option: A self-adhesive bituminous waterproofing membrane that forms a barrier against vapour and gases. EshaBase Alu.Guidance for specification option: EshaBase Alu is a torch applied aluminium cored vapour barrier for bituminous roofing-systems. EshaBase SA Alu 3 mm.Guidance for specification option: A self-adhesive SBS modified Vapour Barrier for bituminous roofing system. EshaBase SA Alu 4.2 mm.Guidance for specification option: A self-adhesive SBS modified Vapour Barrier for bituminous roofing system. EshaBase SA Sand.Guidance for specification option: A self-adhesive SBS modified Vapour Barrier for bituminous roofing system. |
Insulation | |
Type | ProTherm Mineral Wool.ProTherm Mineral Wool Tapered.ProTherm PIR Adhered.Guidance for specification option: A rigid Polyisocyanurate (PIR) foam insulation for use in single ply roofing-systems on suitable surfaces. ProTherm PIR Adhered Tapered.Guidance for specification option: A rigid Polyisocyanurate (PIR) foam tapered insulation for use in single ply roofing-systems on suitable surfaces.
