Moorgate Exchange is an exciting 235,000 ft² development in the City of London. This speculative development has two roof level plant floors and a two-story basement. The architect designed a large rectangular block, with a roof line that is dominated by angled tops that allow for roof gardens on six different levels.

The original piled design was changed to a raft across the whole site, due to its close proximity to the Crossrail tunnels and Moorgate Underground Station, which sites directly beneath the site. The change in design allowed for an extra 300 mm of headroom in the basement. This Skanska project is an excellent example of how Xypex Admix can be used to simplify the production process of waterproofing and concreting, as this can be achieved simultaneously. One of the key influences for the decision making process of adopting the Xypex system as the waterproofing strategy was the total cost savings that was acheived through the whole package. In addition, the site attendance and QA procedures that were implemented assisted the smooth running of the waterproofing for this project. The entire basement is cast utilizing Xypex Admix and the joints sealed using Xypex Concentrate.

Illuminating proof of Xypex permanence and its ability to enhance the durability of concrete structures was clearly evident in a recent test performed by BCRC Pty Ltd (durability consultants) of the precast Cronulla Marina jetty in Sydney, where jetty slabs are exposed to a severe marine environment. Xypex Admix C-2000 NF had been originally blended into the concrete of this jetty in 1994 with superior results. However, the recent test (19 years later) revealed an even more extraordinary Xypex performance: chloride diffusion rates were 92% lower; steel wire reinforcing showed no corrosion; and a projected service life of 129 years – all positive indicators of Xypex’s long-term performance and durability enhancing ability in concrete.
