Excellent cold flexibility to -35?C Excellent elongation Used as a high performance multi-layer tanking membrane in horizontal and vertical applications Also used for waterproofing balconies terraces and roofs
ARDEX WPM 126 is an APAO (Amorphous Poly Alpha Olefin) plastomeric type modified bitumen membrane consisting of a specially formulated bituminous compound of distilled asphalt modified with selected high grade visco-elastic polymers and reinforced with a combined reinforcement (polyester and fibreglass).
ARDEX WPM 126 is coated with either a sanded or talc top surface finish while the bottom surface is embossed and protected by a heat sensitive polythene film. This type of finish for the lower surface has been chosen for two specific purposes.
1. To act as a temperature gauge during application. When the film melts it shows that the compound is at the correct temperature.
2. The embossing is to allow the gases to rapidly escape when heated to its correct installation temperature avoiding possible problems of bubbling and blistering.

ARDEX WPM 126 is used as a high performance
multi-layer tanking membrane in horizontal or vertical
applications also for waterproofing balconies terraces
and roofs. This product is particualry suitable for
extreme cold conditions. ARDEX ARDEX WPM 126
membrane is a sandwich membrane and must be
protected from UV.
ARDEX WPM 126 is also available as a fibre backed
membrane for bonding to substrates and in a slate
mineral finish for exposed conditions.
The application of ARDEX WPM 126 should be carried
out by an accredited applicator.
Installation shall be strictly in accordance with the
Acceptable substrates to which ARDEX WPM 126 is to
be installed must be properly prepared prior to
All surfaces must be dry clean smooth free of sharp
edges loose or foreign materials oil grease and other
materials which may damage the membrane.
Prior to the application of ARDEX WPM 126 base
substrate surfaces should be primed with ARDEX WPM
240 (Shelterbit Primer). Coverage of primer will depend
on the porosity of the substrate.
ARDEX WPM 126 is normally fully bonded to the
prepared substrate with side laps of 100mm and end
laps of 150mm. Overlaps shall be sealed by torch.
ARDEX WPM 126 may be used in various combinations
to produce a variety of specifications tailored to suit the
individual waterproofing need.
The exact specification will depend on functional and
economic requirements. Advice should be sought for
suitable specification from ARDEX Australia Pty Ltd.
ARDEX WPM 126 is hazardous; non-dangerous goods.
However during installation exercise caution when working
with open flame. Examine all surfaces to which the flame
has been applied for smoldering or burning conditions.
Do not use open flame on or near highly combustible
materials. Follow all local fire codes.
All rolls of ARDEX WPM 126 should be stored in a
covered area protected against sunlight and UV
radiation. Rolls should be stored in a vertical position on
a smooth floor so as not to damage the edges.
Roll size: 1m x 10m
Roll weight: Approximately 40kg
Rolls per pallet: 20
