1.11
Where so designated on the drawings, surfaces shall have a self-adhesive modified bituminous waterproof membrane applied. The waterproof membrane shall be protected by a drainage and protection membrane.
1.12
General
All surfaces shall be prepared, primed and the membrane and drainage sheet, applied strictly in accordance with the current manufacturer technical data sheet.
All work shall be carried out by a pre-qualified contractor, who is well trained in the application of the specific, documented, membrane system.
All materials used in conjunction with the new membrane systems, shall be approved by the membrane supplier.
1.13
Surface Preparation
All surfaces to which the new membrane is to be applied, shall be smooth, clean, dry, and free from irregularities.
Sand / cement fillets, polymer modified, shall be installed at all change in direction of substrate locations (e.g. from horizontal to vertical). With sheet membranes all internal and external corners shall be double detailed in accordance with the manufactures recommendations.
All substrate cracks and surface imperfections are to be filled, sealed and dry prior to membrane application.
1.14
The waterproofing membrane is to incorporate a cross laminated HDPE film. The bitumen compounds used to manufacture the product are to be modified with SBS to promote maximum adhesion to the substrate, and shall exhibit the following properties:

> 180% transverse
Total thickness: / 1.6 mm
Tensile strength (film): / 42 N/mm2 longitudinal / ASTM D882
48 N/mm2 transverse
Tear strength (film): / 340 N/mm longitudinal / ASTM D1004
310 N/mm transverse
Low temperature flexibility: / -15oC
Crack bridging capability: / > 1.5mm / ASTM C836
1.15
The protection and drainage membrane shall comprise a layer of polypropylene geotextile fabric manufactured from a continuous filament yarn and dimpled high density polyethylene (HDPE) membrane. It shall exhibit the following properties:
Compression resistance: / >200 kN/ m2 (20 t/m2) caStud height: / 8 mm
Studs per square metre: / 1860 (approx.)
Air volume between studs: / 5.5 l/ m2 (approx.)
Drainage capacity: / 4.6 l/ m2/ s
Thermal stability: / -40oC to +80oC
