Waterproofing London's Fourth Tallest Building
September 13, 2010
Xypex Admix C-1000 was used to waterproof and protect the below-grade concrete slab and elevator pits of this 28-storey skyscraper. Xypex Concentrate Dry-Pac was then installed in all floor-wall joints followed by a slurry coat application of Xypex Concentrate. Changing the skyline, the Willis Building is the fourth tallest building in London. Its progressive environmental strategy surpasses statutory carbon reduction targets and meets the highest standards for sustainability. Over 15,000 cubic metres of concrete were used in its construction.
Located in the heart of London's financial district, the Willis Building is the new headquarters of the global insurance broker, Willis Group Holdings. Designed by world-renowned architects Foster + Partners, the building won the New City Architecture Award for its unique architectural form and contribution to the streetscape and skyscape of the City of London. The project is significant in both urban and environmental terms. Most of the material from demolition of the previous building was recycled and crushed for use in the 38-metre-deep foundations.
