Where so designated on the drawings, surfaces shall be waterproofed with a high performance,
two-layer torch on, reinforced, polymer-bitumen waterproofing membrane system with the top
layer also root resistant.
The membrane system is to be overlaid with a dimpled protection and drainage membrane in
high density extruded polyethylene with continuous filament yarn geo-textile.
1.12
General
All surfaces shall be prepared, membrane applied strictly in accordance with the current supplier
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 system, shall be approved by the
membrane supplier.
1.13
Surface Preparation
All membrane substrate surfaces shall be smooth, clean, dry, in a sound state and free from
irregularities and any contamination.
Polymer modified sand / cement fillets shall be installed at all change in direction substrate
locations (e.g. from horizontal to vertical). With sheet membranes all internal and external
corners shall be double detailed in accordance with the manufacture’s recommendations.
All substrate cracks and surface imperfections are to be filled, sealed and dry prior to membrane
application.
