What is Wolfin?

The Wolfin membrane itself is a Polyester-PVC compound with no leachable plasticiser. The overall system (membrane, steel profiles, liquid and cast-in details) is made in Germany.

The membrane is always used in conjunction with the profile system and the design philosophy is completely self-sufficient waterproofing.

In addition to the basic Wolfin - Wolfin IB - there are other Wolfin variants that have the Wolfin IB as a basic component.

Wolfin laid to waterproof building built in Sydney suburb of Sans Souci. Ground Floor built 0.5 metres under high-water mark.

The other membrane variants expand the system's useability in more specialised applications. All types have excellent UV and variable temperature behaviour and the technical details are similar to Wolfin IB.

Wolfin complies with AS1530.3 as to heat and fire tests.

• Wolfin IB:
1.5 mm: Standard general purpose membrane - useful for new and retrofit roofing and liquid containment applications - allows most existing failed materials to stay. Colours are light grey or black.

2 mm: The same as above, but stronger for more onerous duty, such as girder tops on transom-top rail bridges or heavy-duty expansion joints. Colour - black.

• Wolfinsteel: This is 24 gge galvanised steel with an 0.8 mm thick layer of Wolfin factory bonded to one side. This is used for terminations (and intermediate fixings where required, such as high walls or long spans) and can be cut and bent to any desired size or shape.

All such details are encapsulated, as are all fixings and are predominantly designed to act in shear. They are also useful for fully integrated cappings and overflashings, and can be decorated (painted) if desired with any good quality acrylic coating. Standard colours are light grey or black.

An underground tank was lined with Wolfin at HMAS Harman Naval base in Canberra. The tank holds water for the cooling system of the base.

• 316L Wolfinsteel: This is the same as the Wolfinsteel above but the steel used is Low-Carbon Stainless Steel. This variant of the Wolfinsteel is used where there are particularly severe corrosion issues.  Black only.

• Wolfin AF 6: An extruded section made of Wolfin IB, which is cast into concrete to form an efficient reglet termination, or intermediate strong point.

• Wolfin M (reinforced - high tensile, low elasticity): The Wolfin IB with a polyester reinforcement embedded into the middle - useful where very high (1600 Nmm2) tensile behaviour is sought and elasticity is less critical. Note, when stressed to reinforcement failure the normal behaviour is a local breakage of the mesh, with no break of the parent membrane - the membrane reverts to its normal elastic state (300%+), reducing consequential risk.

• Wolfin GWSK (reinforced heavy duty self-adhesive): Standard Wolfin IB membrane with a fibreglass reinforcement mesh embedded on one side and coated on that same side with a powerful modified bituminous adhesive. Useful for heavy duty adhered systems where peel and stick is desired and also directly under asphalt. This is the standard membrane for roadworks.

Wolfin was used to line the bathrooms of Australia’s largest backpacker hotel in Sydney. The bathrooms were lined to ceiling height in all cases so that high-pressure water could be used to clean the bathrooms without allowing water penetration. The building is of internal timber construction.

• Wolfin S (standard self-adhesive): Similar to GWSK but with a thinner layer of adhesive backing. Useful for all locations where full bond is required.

• Wolfin Tec E (repair strip): 0.8 thick Wolfin with a powerful adhesive layer - supplied in 165 mm wide x 15 metre long rolls. The adhesive will adhere to any membrane system on the market including EPDM. It will also adhere to steel, concrete & timber.

• Wolfin Corners: Preformed Internal and External corners for a tighter neater look. The Wolfin membrane welds direct to the corners.

• Terostat Fixband : 120mm wide Self-Adhesive tape used to seal Wolfin to wall where render to be applied over. Can only be used in balcony or garden bed or small terrace situations. To be used with Wolfin M and Terokal  914.

Wolfin waterproofed roof of Readers Digest building so that entire roof could be used for extensive rooftop gardens including mature trees and ornamental stream.

• Terokal Alufixband: 120mm wide self-adhesive tape used to seal Wolfin to wall. Can only be used in balcony or garden bed or small terrace situations. To be used with Wolfin M and Terokal  914.

• Terokal 914: High Strength adhesive to be used with Wolfin. Can be used against steel, concrete, timber and all non-porous surfaces.
