Newton waterproofs a Luxury Private Club in Earls Court

  • 20 Mar 2019

Newton Waterproofing Specialist Contractor, Stonehouse Property Care, was recently called on to provide a guaranteed waterproofing solution in the basement of a new build multi-residential and commercial development to house a luxury private residents club.

The Project

The below-ground resident’s clubhouse also includes a luxury subterranean swimming pool.

The Lillie Square development in Earls Court, London will eventually comprise of over 800 multi-million-pound luxury dwellings, stretching from Chelsea football ground to Kensington Olympia. 

Phase 1 of the project required the formation of a watertight basement to house London’s largest private residents club which serves the entire property development.

At an early stage, Newton Specialist Basement Contractor Stonehouse Property Care were consulted to be part of the design team, along with the main contractor Sir Robert McAlpine, to provide a guaranteed waterproofing solution that would comply with the requirements of both BS 8102:2009 and any third-party warranty providers.


The Solution

This clubhouse atrium artists’ impression gives a sense of the scale of the above and below-ground areas.

The solution was to design a combined waterproofing solution using three forms of waterproofing to avoid the risk of any future moisture ingress which would damage the high-quality finishes and disrupt club members.

Stonehouse applied the principle of BS 8102:2009 to create a Grade 3 (habitable) internal environment. This involved external Type A (barrier), and integral water-resistant Type B concrete barrier and a full internal Newton Type C cavity drain system. Stonehouse installed 4 sump chambers, 8 sump pumps and 4 battery back-up systems together with the targeted application of Newton 107F reinforcement at vulnerable positions within the construction.

This Newton system forms the crucial barrier to any risk of water ingress and has an extendable 10 Year Guarantee with independent insurance backing. Stonehouse Property Care will service the pumps annually and provide support if required.

The Type A system was achieved with the Newton HydroBond System utilising Newton 107F cementitious, liquid-applied waterproofing membrane, a Type B concrete barrier, and the Type C internal waterproofing using the Newton CDM System cavity drain waterproofing, installed throughout the basement area of the clubhouse, with four Newton Titan-Pro sump chambers containing dual Newton NP400 pumps, as well as Newton High Water Alarms, Inverters and Battery Back-Up protection creating a truly failsafe system.

The large Newton cavity drain membrane installations were achieved using special Newton MultiPlugs.

Graham Stone, Managing Director, Stonehouse Property Care, Newton Specialist Basement Contractor, comments: “Stonehouse Property Care have worked closely with Newton Waterproofing Systems for almost 20 years, and we wouldn’t want to work with any other waterproofing supplier on such a large scale, luxury new build project as Lillie Square. The quality of their waterproofing materials combined with their on-site installation and technical support means I can confidently specify, install and guarantee a fault-free waterproofing solution, and ultimately provide the best result for the client.”

The Result

Newton Waterproofing and Stonehouse Property Care were able to work with Sir Robert McAlpine from the design stage, making it possible to consider the lifetime performance of the structure as well as the cost in order to design and install thorough waterproofing protection.
