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.

Once an area is waterproofed, we can either render directly on to the CDM or provide a ‘dry line’ plaster finish.

Where there is not a gravity fed option, the Cavity Drain Membrane system is supported by a pumped system.

Many architects now recommend the installation of a water collection channel, pictured right, which can be bedded into a preformed channel at the floor/wall angle. Holes in the channel wall allows water to ingress at this point to drain away to a sump. Rodding eyes are available to allow maintenance and inspection.
