Renzo Piano involved RIW in the design process for this iconic building on London’s South Bank.
The mixed-use, 1016ft tall ‘vertical city’ will be the tallest building in Western Europe and is therefore in need of a solid basement waterproofing strategy. The site sits in a low-risk area with regards to the water table, and watertight concrete provides significant protection against water ingress. However, the depth of the basement means that additional waterproofing assurance is needed to completely seal the plant rooms.
Another requirement was to enhance the traditional ventilated drained cavity design, to ensure water ingress through deep-piled walls was contained within a channel behind a blockwork lining wall.
RIW Toughseal was specified and used as a chemically resistant and waterproof coating to plant room floors within the basement, to protect adjacent rooms from water damage.
RIW Toughseal was the ideal membrane to be applied within the channel behind the blockwork lining wall, where limited access restricted working space.
