ARDEX WPM 1000 Weldable Waterproofing Membrane
ARDEX WPM 1000 Weldable Waterproofing Membrane is a
versatile rubber membrane that can be heat welded. It is suitable for
waterproofing underground tanking, rooftops, decks, undertile, canal and pond
ARDEX WPM 1000 is made up of synthetic rubber with
properties which resist ageing from heat, sunlight and ozone and is heat
weldable. Polypropylene filaments are welded onto both sides of the membrane
for better wetting by water based adhesives. It has excellent gas
impermeability and toughness and remains flexible at low temperatures.
Laps and corners are to be heat formed and/ or welded.
Tiling can be done directly on the membrane after 60 minutes with common ARDEX
tiling adhesives like X77, X56 STS8/ E90, Quickbond/Abalastic, 2 part Optima or
ARDEX requirements for long term warranty necessitate
that the ARDEX WPM 1000 meets these typical technical requirements:

Ozone Resistance to
ASTM D1149 - 7 days
at 40oC in 50pphm ozone No visible cracks
ARDEX WPM 1000 resists tearing, flex cracking, bubbling
and abrasion. It is extremely strong, has a long life and is versatile.
In rolls of nominal 1.4m width and 20m long. Each roll is
packed in polythene wrapper trademarked ARDEX WPM 1000.
ADHESIVES FOR USE WITH ARDEX WPM 1000
ARDEX WA98 - The standard contact brushing, spray grade
and rolling solvent free adhesive for fixing to the substrate. Supplied in 20L
ARDEX WPM 1000 when fixed according to ARDEX instruction
will meet the NZBC requirements of B2.3.1(b) 15 years.
SUBSTRATE SPECIFICATION Plywood & Timber
Substrates must be dry when ARDEX WPM 1000 is applied.
The plywood and timber substructure shall have a maximum moisture content of
20% when ARDEX WPM 1000 is adhered. NOTE: LOSP (Light Organic Solvent
Preservative) treated plywood must NOT be used under ARDEX WPM 1000 in any
circumstances or conditions.
Must be cured for a minimum of 28 days and all curing
compounds removed prior to application. A reduction in cure time can be
achieved by utilising the ARDEX HydrEpoxy System (consult ARDEX Technical
Department for details).
Old Concrete Must be clean from any contaminants prior to
OTHER SUBSTRATE TYPES Fibre cement compressed sheet,
closed cell polyurethane foam, wet wall linings i.e. Gib Aqualine, VillaBoard.
Roll out ARDEX WPM 1000 and cut to the measured length.
Smooth ARDEX WPM 1000 on contact to minimise air entrapment beneath the
membrane. Floor sheets of ARDEX WPM 1000 must extend up the wall at least
150mm. Make sure the ARDEX WPM 1000 is laid tightly into all corners. Wall
sheets of ARDEX WPM 1000 should overlap the 150mm upstand. Weld seams and laps
with the Leister Triac S Hot Air Gun. Roll with a rubber roller to ensure seams
and laps are secure.
Walls, internal corners & transitions
Apply the ARDEX WPM 1000 membrane 1800mm up the walls or
to a height of 150mm above the shower rose. For unenclosed showers the membrane
must extend a minimum of 1500mm out from the shower rose.
ARDEX WPM 1000 is not suitable as a trafficable
surface. ARDEX WPM 1000 is compatible with undertile heating systems. For
electric undertile heating, the wire must be covered with a thin screed prior
to laying the membrane. It is the responsibility of the main building
contractor to ensure all sub-trades likely to be working in the vicinity of the
membrane are aware that a waterproofing membrane has been installed and all
care must be taken to protect the membrane from damage. The tiler must lay
tiles in accordance with best practice guidelines
