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:
