Preparation | |
Horizontal work | Activator-Primer (Canister) APR01 – Black.Guidance for specification option: Synthetic rubber resin-based primer, developed to provide the necessary preparation of substrates prior to the installation of self-adhesive and torch-applied membranes. The spray application offers improved film thickness speed of application (by up to 50% over roller applied products) and quick drying in a matter of minutes.
SA Bonding Primer.Guidance for specification option: For Self-Adhesive membranes to Concrete. Bauder SA Bonding Primer is a synthetic rubber-based primer applied by a roller or brush. Specially formulated to increase the bond strength of Bauder self-adhesive bitumen membranes to a wide range of substrates, including timber, concrete, brick, metal and most plastics.

Waterproof covering | |
First layer | |
Type | BauderTEC Sprint DUO.Guidance for specification option: Elastomer bitumen self-adhesive underlayer with variable technology for lap sealing. The two side laps of the membrane have differing finishes. On one lap there is a self-adhesive finish, whist the opposite lap has a glass fleece. This allows the membrane to be sealed with either a gas torch or hot air welder.
|
Attachment | Self-adhered. |
Top layer | |
Type | BauderPLANT E 42.Guidance for specification option: Elastomer-bitumen torch on capping sheet with root-resistance according to FLL. The product features a spunbond polyester reinforcement to allow the finished product to cope with structural movement without fracture.

Flashings | Bauder GRP Trim.Guidance for specification option: GRP roof edge trim for use with Bauder bituminous roof systems. Available colours of either grey or black and a choice of profiles to suit the requirements of most projects. Bauder GRP Water Check Trim.Guidance for specification option: GRP water check trim to be used on parapets and perimeter kerbs wider than 200 mm – must not be used on its own as a check kerb. Available in black only. Bauder Aluminium Termination Bar.Guidance for specification option: Natural finish aluminium alternative to a lead counterflashing for use at upstand details to give protection to the top edge of the waterproofing. It should be restricted to use on upstands where a chase cannot be cut into the wall. Bauder GRP Termination Bar.Guidance for specification option: Black glass reinforced plastic (GRP) alternative to a lead counterflashing for use at upstand details to give protection to the top edge of the waterproofing. It should be restricted to use on upstands where a chase cannot be cut into the wall. |
Skirtings and upstands | Bauder LiquiFIBRE Detailing Kit.Guidance for specification option: Fast curing waterproofing resin containing fibre reinforcement that can be used for detailing awkward shapes or inaccessible areas where using LiquiDETAIL is impractical. PMMA-based resin that requires a catalyst and is solvent, isocyanate and halogen free. Bauder LiquiDETAIL.Guidance for specification option: Cold liquid applied fast curing waterproofing resin that can be used on upstands and details. PMMA-based resin that requires the addition of catalyst to trigger curing and is solvent, isocyanate and halogen free. |

|
Ballast | Manufacturer guidanceInsert requirements - Consult Bauder for information. Please refer to Bauder Extensive / Biodiverse / Intensive / Hard Landscape Landscaping systems. Loading over inverted insulation (minimum): Ballast (landscaping) should be installed onto the Bauder WFRL Membrane (Water Flow Reducing Layer) to a minimum depth required to achieve a permanent minimum 80 kg/m² and load which prevents wind uplift and flotation of the insulation in high winds and/or heavy rainfall. |
System accessories | Not required.Bauder lightning conductors.Guidance for specification option: Lightning conductor clips are a specially designed secure clip that allows for movement.
Bauder rainwater outlets.Guidance for specification option: Bauder has a range of insulated or stainless-steel rainwater outlets. The insulated outlets can be used for maintaining thermal continuity at drainage points. Suitable for warm, cold and inverted roof construction, the high thermal value of the rigid foam body prevents condensation from forming on the underside of the outlet. Designed for use when connecting to conventional drainage systems, with excellent flow rate performance and is suitable for both new build and refurbishment projects. Outlets are included in the Bauder waterproofing system guarantee as they are integrated components. Flow rate figures (where applicable) are based on BS EN 12056:3:2000, typically taken using a 35 mm header of water including leaf grille:
Bauder rooflights/ glazing/ ventilation.Guidance for specification option: All these glazing products are fully compatible with the roof waterproofing systems. Consult manufacturer for details and insert requirements.

Water Flow Reducing Layer/ Vapour Permeable Membrane | Bauder JFRI WFRL. Guidance for specification option: Flexible and breathable sheet of polypropylene strands randomly spun-bound together, supplied as part of the JFRI Inverted Insulation system to minimize water flow through and below the insulation, therefore improving thermal performance. Supplied as part of the JFRI Inverted Insulation system to minimize water flow through and below the insulation.
Bauder XPS WFRL. Guidance for specification option: Flexible and breathable geotextile membrane of polypropylene strands randomly spun-bound together, supplied as part of the Bauder XPS GG Inverted Insulation system to minimize water flow through and below the insulation, therefore improving thermal performance. Supplied as part of the XPS GG Inverted Insulation system to minimize water flow through and below the insulation.
