Case Study The Royal Household Kensington Palace
Harrison Waterproofing is an authorised and recommended installer for the two leading methods of internal waterproofing systems in Britain.
Where the water pressure is particularly high, where noise and dust are likely to cause concern or where it’s required to retain the existing features of a building, we generally recommend a Cavity Drain Membrane (CDM) system, to control damp or water ingress.
With a CDM system any moisture is allowed to pass through the masonry. Thereafter it’s controlled by the use of a waterproof, ‘eggbox’ design, High Density Poly Ethylene membrane, attached to the masonry.
This system was used by us when we worked on a waterproofing project for Kensington Palace, preventing the flow of water through the walls in the underground vaults.
