Shelterbit 120 Membrane

2.5mm Combined Reinforced APP Bitumen

ARDEX WPM 120 (Shelterbit Fibrepol 120) 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 combined reinforcement carrier.

 

ARDEX WPM 120 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 to -5?C • Excellent elongation • Heat welded laps provide homogenous joint • Prefabricated membrane • Good elastic memory Combined reinforcement carrier • High mechanical characteristics • High puncture resistance • Will not decay USES ARDEX WPM 120 is used as a base and or mid layer in multi-layer tanking membrane systems in horizontal or vertical applications also for waterproofing balconies terraces and roofs. ARDEX WPM 120 membrane is a sandwich membrane and must be protected from UV.

 

INSTALLATION

The application of ARDEX WPM 120 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 120

is installed must be properly prepared prior to

membranes 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 120 the 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 120 is normally fully bonded to the

prepared substrate with side laps of 100mm and end

laps of 150mmm.

Overlaps shall be sealed by torch.

ARDEX WPM 120 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 specifications from ARDEX Australia Pty Ltd.

SAFETY PRECAUTIONS

ARDEX WPM 120 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 120 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 15m

Roll weight: 43.5kg

Rolls per pallet: 23
