Newton System 500 used to waterproof the British Museum's below ground vaults and arches after a previous system had failed
Waterproofing the British Museum
The project was to install a waterproofing system to the basement vaults of the east residence of the British Museum. This highly sensitive listed structure needed to be waterproofed to a Grade 3 Habitable environment in accordance with BS812:1990
The area was previously waterproofed with a Type A cementitious system which had failed and the artefacts stored in the area were subjected to water damage.
Waterproofing the British Museum with Newton System 500 involved applying Newton 508 Mesh to the vaulted arches and walls with Newton Basedrain installed within a rebate at the wall floor junction. A rendered finish was applied and Newton 508 was laid to the floors with a screed finish. The Basedrain allowed for non pressurised movement of water to the sump and pump system for removal.
17 Listed Vaults (1100 sq metres) of the Museum are now being fully utilised as locker and rest rooms for the staff. All treated areas are now dry and fit for purpose.
The speed of application of the Newton Water Management System meant that the project cycle of the job from start to finish was 7 weeks.
The architects involved preferred the Newton System 500 as this technique was deployed with minimal disruption and was deemed a more sympathetic approach to the listed structure.
