Roofing team rises to tower challenge

BRIGGSAMASCO has revealed details of its work to install a weathertight solution to three huge towers for a luxury high-rise project in Manchester city centre.

The Oxygen development is located in the city’s New Islington district, with the ‘vertical neighbourhood’ comprising a 32, 16 and 10-storey tower.

The scheme, designed by Jon Matthews Architects on behalf of Property Alliance Group, comprises 12 townhouses, 361 apartments, and seven penthouses.

For the towers’ waterproofing, BriggsAmasco was selected by main contractor Russell WBHO to supply a system comprising an IKO Permatec hot-applied, self-sealing membrane, as well as a rigid insulation board.

To counteract the threat of wind uplift, the firm installed a dense level of ballast and 63mm paving slabs as a finish for each roof.

Each tower was linked by a lift and a stair core, with both containing over runs. These were sealed by BriggsAmasco using an IKO system featuring a self-adhesive vapour control layer and a self-adhesive underlay with a torch-on capsheet. Teams also installed the IKO Permatec hot-melt membrane to a groundfloor podium which surrounds each tower.
