CHARTER SQUARE STAINES

Charter Square revives a neglected stretch of high street in Staines-Upon-Thames as part of a wider mixed-use masterplan. This first phase contributes 260 of the homes which are accommodated in a cluster building, complete with a communal garden at fourth floor, roof terraces, gym and concierge. 

FIS were pleased to support London Square and Carey London with the design and supply of the sub-structure waterproofing. The development was identified as lying in a flood zone, therefore extra protection was needed to ensure the waterproof line of defence extended to above the line of risk. The basement structure largely consisted of carpark, however there were grade 3 zones including highly critical UKPN switch rooms.

FIS designed the waterproofing using Maxiprufe 2000 bentonite membrane and Hydrocrete Watertight Concrete admixture, to provide two lines of defence where required.
