Guidance for specification option:

• Setting out: Loose lay insulation directly on to the filter fleece over the waterproofing to brick pattern with staggered joints. Minimize cutting and avoid small pieces at perimeters and penetrations. Dependent upon the total thickness required, it may be necessary to construct the insulation using two layers of board. The manufacturer/supplier can advise on the available combination options.
• Joints: Butt together.
• 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.
• Additional loading at perimeters: On high buildings in more exposed areas, wind uplift may be a problem and in these instances paving slab ballast must be considered. Paving slabs should be a minimum of 50 mm thick. The slabs should be laid on paving slab supports of minimum 175 mm diameter (or equivalent base area).
• All final details must to be confirmed with Bauder before proceeding.

Guidance for specification option:

Important note: To be used on parapets and perimeter kerbs over 200 mm in width – must not be used on its own as a check kerb.

• Product: Bauder GRP Trim Angle
• Length: 3 m
• Face depth: - 100/60 Angle: 60 mm - 150/75 Angle: 75 mm
• Fixing arm: - 100/60 Angle: 100 mm - 150/75 Angle: 150 mm   

Installation:

- Carrier Membrane (where applicable):

- Apply the specified primer to the detail and dress the carrier membrane up and over the perimeter detail. Please refer to Bauder standard detail drawings.

Setting out: The new trim must cover any open joint, which may exist between the kerb and the top of the wall by a distance of minimum 20 mm.The trims must be bedded in Bauder LiquiPASTE and mechanically fixed with corrosion resistant flush headed screws. Fasteners: Screw fasteners of type appropriate to kerb or deck substrate. Nail fixing is not permitted.

Fixing: 30 mm from ends and at 300 mm (maximum) centres, stagger fixed. In high wind risk areas or above 10m high, fixing centres are to be at no more than 150 mm Corner pieces: Purpose made to suit orientation of trim. Completion: Contact surfaces: Clean with Bauder PMMA Cleaner to remove dust or any other contamination from the trim surface. Mask off the top of the trim recess.

- Waterproofing:

Dress the full Bauder LiquiDETAIL system over the trim to its full extent and past the edge of the downward facing edge. Once the system has cured, the excess is to be trimmed off to a neat finish.

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.

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.
