PRODUCT DESCRIPTION

ARDEX WPM 122 is an A.P.P. (Atactic Polypropylene

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 high quality non-woven 300g polyester carrier. ARDEX

WPM 122 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.

FEATURES AND BENEFITS

A.P.P. modified compound

• Excellent cold flexibility -10?C

• Excellent elongation

• Heat welded laps provide a homogenous joint

• Prefabricated membrane

• Good elastic memory

• Resistance to aggressive chemicals

Heavyweight non-woven polyester

• High mechanical characteristics

• High puncture resistance

• Good elongation

• Will not decay

USES

ARDEX WPM 122 has been specifically engineered

using a heavy weight non-woven carrier for heavy-duty

applications particularly as a membrane under hot

melt asphalt or bitumen.

Typical uses are:

• Bridge decks

• Car parks

• Road-ways

• Viaducts

ARDEX WPM 122 is a sandwich membrane and must be

protected from UV radiation.

INSTALLATION

The application of ARDEX WPM 122 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 122

systems are 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 122 the surface

should be primed with ARDEX WPM 240 (Shelterbit

primer). Coverage of primer will depend on the porosity

of the substrate.

ARDEX WPM 122 is fully bonded to the prepared

substrate with side laps of 10cm and end laps of 15cm.

Overlaps shall be sealed by torch.

ARDEX WPM 122 is used as a single layer membrane

system which is normally installed prior to the installation

of toppings road base or hot melt asphalt or bitumen.

Application of toppings may be applied on completion.

Road base may be installed directly to the membrane

without an extra protection layer.

The asphalt should be applied as soon as possible after

the ARDEX WPM 122 membrane has been installed.

ARDEX recommend applying a minimum 50mm

compacted overlay for carpark areas. The topping

should be applied in two layers at a temperature of

between 120-150?C.

The exact specification will depend on functional and

economic requirements. Advice should be sought for

suitable specifications from ARDEX Australia Pty Ltd.

SAFETY PRECAUTIONS

ARDEX WPM 122 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 smouldering 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 122 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.
