Mobile Lift Pit with Wolfin IB Membrame from Projex Group

The Brisbane Airport Corporation, as part of its ongoing commitment to maintaining and improving the Domestic Terminal Precinct, is currently undertaking upgrade works at the Common User Satellite. In any multi-storey building lifts are usually required and the Common User Satellite is no exception.

The builder faced a major problem when it came to the construction of the lift over-run pit because the base of the pit would be 300 mm below the high tide mark.

To overcome this the lift pit was formed and poured at a casting area within the airport grounds. When the concrete had cured sufficiently to lift, the unit was placed on a preformed sheet of Wolfin IB membrane that had been covered with 5 mm Projex Shockmat to avoid damage to the membrane when the pit was placed onto it. When the pit was in place on the Wolfin membrane, the outer face of the walls were lined with Wolfin GWSK and the two Wolfin materials were married together. The "bagged" pre-cast lift pit was then placed onto a heavy duty trailer and hoisted into place at low tide with the use of a 200 tonne crane.

The Wolfin was chosen because of its proven ability to withstand oil-based chemicals of the type found around airports and its ability to withstand regular immersion and dry cycles.

The Wolfin and Shockmat were installed by Caps Beta Pty Ltd.
