Newton provides waterproofing for Grade II Listed vaults under Central London

  • 7 Aug 2019

Newton Specialist Contractor, Stonehouse, was recently called in to waterproof four of the Grade II Listed underground vaults that lie beneath the streets of Central London.

The aim for the project was to turn the four impressive structures, situated just North fo the River Thames, into a completely dry commercial space for the multinational service provider, KPMG.

The Grade II Listed structures are each over 4 metres in height, and form part of an impressive below-ground infrastructure network. 

Newton’s CDM System provides the ideal solution as it is maintainable, requires minimal fixings and therefore avoids damaging the structure, and crucially is deemed as reversible should the structure need to be returned to its original condition in future.

As an experienced contractor, Stonehouse proceeded with an expert installation of a full CDM System to the tricky vaults, including:

– 508 Mesh membrane to the walls, for a direct plaster finish
– 508 membrane and Fibran XPS 500-C insulation boards to the floor
– Basedrain channels to direct any captured water towards two Titan-Pro sump chambers,
each containing two NP400 pumps
– Victron Inverter and a NorthStar battery for reliable back-up power

Stonehouse completed an extremely complex and detailed cavity drain installation with precision, resulting in an exceptionally neat waterproofing system, and proving the benefits of using a specialist waterproofing contractor.

Richard Allen CSRT CSSW, Senior Surveyor at Stonehouse, comments: “In over 30 years in the waterproofing industry this was one of the most complex and physically challenging projects I have been involved with. However, our installation team rose to the challenge and produced a first-class installation of the high-quality Newton products with pinpoint accuracy. We were also well within the program laid down by the main contractor, who stated that they were “impressed by the professionalism and commitment of all of the Stonehouse team on site”. ”
