External Waterproofing system (UV exposed membrane)
1.11
Where so nominated on the drawings, surfaces shall be waterproofed with a water based,
solvent free, liquid applied polyurethane membrane.
The membrane shall meet the requirements of the following standards:
•
AS/NZS 4858:2004 Wet Area Membranes as a Class III membrane
•
AS 3740:2010 Waterproofing of Wet Areas Within Residential Buildings
1.12
General
All surfaces shall be prepared, primed and the 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.
All substrate cracks and surface imperfections are to be filled, sealed and dry prior to membrane
application.
1.14
Priming
The primer is to be compatible with the water based membrane, and provide high bonding and
penetrating properties to porous substrates such as concrete and masonry.
To non-porous substrates, an alternative solvent free, specifically designed compatible primer, is
to be used.

Membrane Junction Systems
All wall to wall and floor to wall junctions, internal and external corners are to incorporate an
elastic, preformed corner and joint band into the membrane system, to accommodate any
movement at these junctions.
Alternatively, apply a compatible polyurethane sealant caulking fillet to these junctions. The
sealant must be fully compatible with the nominated membrane.
1.16
Waterproofing Membrane
The waterproofing membrane is to be water based, solvent free, liquid applied polyurethane.
It shall exhibit the following properties:
Elongation:
> 355%

UV Protection Membrane Top Coat
Where the membrane is to be UV exposed, the membrane layer is to be protected from ‘UV’
deterioration by the application of hard wearing, solvent free polyurethane, foot trafficable
membrane.
2.10
The top coating is to be hard wearing, non-shrinking, flexible, with a non-slip surface, exhibiting
the following properties:
Elongation:
Tensile strength:
Adhesion to concrete:
Shore A hardness:
Colour:
Slip resistance R Rating:
> 80%
> 2.2 MPa
> 1.6 MPa
