4.0mm Combined Reinforced APAO Bitumen Membran

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.

USES

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.

 

 

 

INSTALLATION

The application of ARDEX WPM 126 should be carried

out by an accredited applicator.

Installation shall be strictly in accordance with the

manufacturer’s recommendations.

Acceptable substrates to which ARDEX WPM 126 is to

be installed must be properly prepared prior to

membrane installation.

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.

SAFETY PRECAUTIONS

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.

STORAGE

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.

PACKAGING

Roll size: 1m x 10m

Roll weight: Approximately 40kg

Rolls per pallet: 20
