Loose laid (and suitably ballasted).

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.

Not required.

Bauder 100/60 GRP Trim Angle.

Guidance for specification option:

GRP roof edge trim for use with Bauder Cold Applied Liquid Waterproofing systems where the system is terminated at perimeter details, such as drip edges, watercheck kerbs or parapets.

• Length: 3 m.
• Face depth: 60 mm.
• Fixing arm: 100 mm.

Note: The trim may be used either way round as required.

• Thickness: 2 mm.
• Colour: Black.

Installation:

• The trims must be bedded in Bauder LiquiPASTE and mechanically fixed with corrosion resistant flush headed screws.
• Fixings centres must be no greater than 300 mm with fixings within 50 mm of the ends. In high wind risk areas or above 10 m high, fixing centres are to be at no more than 150 mm.
• 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 reinforced Bauder LiquiTEC System is to be dressed 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.
