Stonehouse Property Care has waterproofed four impressive underground vaults for service provider KPMG for use as commercial spaces.

The Grade II listed structures lie beneath the streets of central London, a short walk from Smithfield Market and St Paul’s Cathedral. They form part of an impressive below-ground infrastructure network and are each over four metres in height. 

The Newton Cavity Drain Membrane (CDM) system offers the ideal waterproofing solution for historic, listed buildings. Maintainable and robust, the system requires minimal fixings to walls and so avoids damaging the structure. It is a reversible system, which is important for listed buildings that may need to be returned to their original condition in the future.

  • Fitting a 508 mesh membrane to the walls, for a finest plaster finish.
  • Fitting a 508 membrane and Fibran XPS 500-C insulation boards to the floor.

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