Shelterbit Garden Membrane

3.5mm Garden APP Bitumen Membrane

Positive vapour barrier

Excellent resistance to pollutants and aging

Good elongation and flexibility

For waterproofing planter boxes garden beds roof gardens

and flower beds

Contains root inhibitor – stops roots from plants damaging

the membrane

 

ARDEX WPM 186 (Shelterbit Garden) is an A.P.P. (Atactic Polypropylene Plastomeric) torch applied modified waterproofing 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 combined reinforcement (fibreglass and polyester) and treated with preventive chemical to stop roots from plants damaging the membrane.

ARDEX WPM 186 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

• Positive vapour barrier

• Excellent resistance to pollutants and aging

• Excellent cold flexibility -5?C

• Maintains shape stability at high temperatures

• High resistance to perforation

• Is rot-proof

• Resists root growth ingress into both the membrane

and the laps

• Good elongation and flexibility

• Heat welded laps provide an homogenous joint

USES

ARDEX WPM 186 has been especially formulated for the

waterproofing of:

• Planter boxes

• Garden beds

• Roof gardens

• Flower beds

• Green covered civil works etc

ARDEX WPM 186 may be installed in a one or multi-layer

system incorporating normal bitumen membranes.

ARDEX WPM 186 always being the top layer.

 

INSTALLATION

The application of ARDEX WPM 186 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 186 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 186 the surface

should be primed with ARDEX WPM 240 (Shelterbit

primer).

Coverage of primer will depend on the porosity of the

substrate.

ARDEX WPM 186 is normally fully bonded to the

prepared substrate with side laps of 10cm and end

laps of 15cm overlaps shall be sealed by torch.

ARDEX WPM 186 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 186 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 186 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 42kg

Rolls per pallet: 23
