Challenge

Newton waterproofing solutions are contributing to the transformation of the unique, Grade 1 listed Cambridge House in Piccadilly as it undergoes conversion into one of London's grandest hotels. The 18,000m2 scheme includes six adjacent Grade 2 listed residences, whilst a four-level basement will accommodate a spa as well as the back-of-house and servicing areas. 

In order to deliver a reliable, watertight solution for this £165m project, Newton worked closely with architects PDP London and leading enabling works contractor Deconstruct UK throughout the design and installation. 

Solution

There are three main buildings where extensive excavations are taking place, requiring different waterproofing solutions to cater for the new-build basement areas and existing elements - all up to 4 storeys below ground. 

Buildings 1 and 3 are both benefiting from full Newton Cavity Drain Membrane System waterproofing, which will capture, depressurise and remove any ingressing groundwater via a series of Trojan-Pro pump chambers.

Building 2 utilises numerous products across new-existing structures, including 403 HydroBond and 315 Polymer-Waterbar to the new concrete attenuation tank, which will also be coated internally with the 102-S liquid membrane. 

The same two products were also used alongside the flexible 107F liquid membrane and 106 Flexproof for construction joint waterproofing in areas where the existing brick structure interfaces with a new concrete slab. Finally, Titan-Pro pump chambers are being installed to remove the water. 

Outcome

As of June 2021, the waterproofing installation is underway and on-track on all three buildings, with Newton's site services team delivering an exceptional quality assurance and training service on installing products.
