Scope of Works
- Hot melt waterproofing
- Cold resin waterproofing
- Glass internal cladding systems
Designed by Uruguayan architect Rafael Viñoly, 20 Fenchurch Street – commonly known as the Walkie-Talkie – is London’s highest public park at 525 ft and one of the most striking new buildings to appear on London’s skyline. At an estimated cost of £200 million, the building has an accessible viewing deck, two restaurants and a sloping sky garden.
Lindner Prater played an integral role in the delivery of this multifaceted skyscraper, meeting the logistical challenges of installing a roofing and waterproofing package for such a complex building.
We were responsible for the inverted roofing system and 2,000 sqm of waterproofing on the ground floor, which helped to form the construction of several huge planters. The majority of materials used were liquid applied Radmat Building Products including ParaFlex and PermaQuik. Glass internal cladding systems were installed over the concrete decks from ground up to the second floor level, and other levels too.
By the nature of its multi-layered top-heavy design, the shape and inventiveness of the building posed many roofing challenges. The roof’s steep angle of 45 degrees meant that installing the waterproofing required precise measurements, an uncompromising approach to health and safety as well as a high level of skill from our delivery team.
The project to deliver the roofing package and waterproofing was completed in 18 months – on time and on budget. Close collaboration throughout the process with Canary Wharf, Land Securities and Crossrail ensured the project was a complete success.
