Kemperol membranes put Piccadilly Gate’s roofs back on track
of Kemperol liquid membranes from Kemper System. Piccadilly Gate is home to various Government departments including Education, Ofsted and Highways England. The 125,000sqft building adjacent to Manchester Piccadilly Station was refurbished in a £25 million BREEAM ‘Excellent’ scheme in 2010. Issues with the integrity of the roof had continually plagued the building with leaks, resulting in unsightly staining to the suspended ceilings within.

This ensures complete saturation of the reinforcement fleece. Once cured, the resin forms a seamless, elastomeric waterproof membrane that cannot delaminate, is UV stable and bonds directly to the substrate. For the green roof on level three, Castle

The level four roof is above the building’s record-breaking extra-long escalators and leaks from two water outlets had caused staining of the suspended ceiling. This roof was also refurbished as an overlay system, using Kemper System’s Kemperol V210. Having cleaned and prepared the existing
Roofing carried out the refurbishment in two sections, removing half the green roof medium and installing Kemperol V210 onto to the existing surface as an overlay before replacing it and lifting the second section so that the new roofing membrane could be installed. The second section was then re-instated, completing the programme.
