This development of prestige high rise residential units with underground parking was situated on a disused gas works on highly contaminated ground and over groundwater. The client was concerned to avoid cross contamination of underground aquifers when drilling bored pile. In addition, Thames Water placed restrictions on the amount of water allowed to be discharged into the sewer system.
We met the requirements of the client and ensured an environmentally friendly outcome through the construction of an impressive and effective 800lm cofferdam with sheet pile of up to 20m in length.
We took a highly technical approach to create a waterproof basement structure; using crack inducing and an advanced injection system.
