Willis Building
At the time of construction the Willis Building was the fourth tallest building in the city. Its progressive environmental strategy surpasses statutory carbon reduction targets and meets the highest standards for sustainability. Over 15,000 m3 of concrete was used in its construction.
This 28-storey skyscraper, opposite Lloyd’s in the heart of London’s financial mile, is the new headquarters of the global insurance broker, Willis Group Holdings. Designed by world-renowned architects Foster + Partners, the building won the 2007 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-meter-deep foundations. Xypex Admix C-1000 NF was used to waterproof and protect the below-grade slab and elevator pits. Xypex Concentrate Dry-Pac was then installed in all floor-wall joints followed by a slurry coat application of Xypex Concentrate.
