Wolfin waterproofs Canberra.

The history of waterproofing in the Canberra region has many failures amongst the different waterproofing systems used. Most of the problems occur because of the wide variance in daily temperatures - where a rooftop can experience -10°C in the early morning and +45°C that same afternoon. Most membrane systems become brittle with such treatment and ultimately break down.

Accordingly when the refurbishment of Scarborough House in the suburb of Woden was planned the architects, MGT Canberra, specified the Wolfin system for the waterproofing of the roof.

In addition to the thermal movements the architects were concerned over the treatment of the cold joints on the roof between the existing roof slab and the new concrete "wings" put in place to increase the roof by just under 50%.

Wolfin S membrane was specified so that the membrane would be bonded to the roof - rather than loose-laid - and a wearing slab was poured over the top of the membrane. The edges of the membrane were welded direct to Wolfinsteel - Wolfins steel system with membrane already bonded to it - in such a way that the system was not reliant on any sealant. The Wolfinsteel was mechanically fastened to the substrate and the fixings were covered in membrane. The Wolfin System is designed to withstand constant variations of temperature without being stressed. The cold joints and other areas of movement concern were treated as expansion joints utilising the Wolfinsteel and unreinforced Wolfin membrane.

Scarborough House belongs to Indigenous Business Australia and the building will be tenanted by the Department of Health and Ageing. The builder for the project was Baulderstone Hornibrook.

On completion of the project the client received a single-point warranty on both materials and labour from Wolfin Membranes Australia.

The Wolfin was installed by S.A Sealants of Canberra, experienced licensed Wolfin applicators.
