Waterproofing the Multi-Level Basement of a Luxury London Hotel with Newton

  • 9 Jun 2021

Newton is proud to contribute to the transformation of the unique, Grade I listed Cambridge House in Piccadilly, as it undergoes conversion into one of London’s grandest hotels. The 18,000 square metre scheme includes six adjacent Grade II listed residences, whilst a four-level basement will accommodate a spa as well as the back-of-house and servicing areas. 

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.

The 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 four storeys below ground. 

Buildings 1 and 3 are both benefiting from full Newton CDM System cavity drain membrane waterproofing, which will capture, depressurise and remove any ingressing ground water 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 103-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, the installation of Titan-Pro pump chambers will remove the water.

The Result

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 the installation of our products.

Newton’s CDM System appeared in another London luxury basement project. You can read about that here.
