Newton Specialist Basement Contractor A P Gooch Ltd were commissioned by the client to provide a robust cellar waterproofing system to protect the Grade II Listed vaults and upgrade them for use to store a sophisticated wine management system and stock of quality wines.
As the vaults were listed, a sympathetic waterproofing system need to be specified and installed. A P Gooch Ltd waterproofed the vaults with the Newton System 500 Cavity Drain Membrane System in accordance with BS8102:2009 Code of Practice for the Protection of Below Ground Structures Against Water from the Ground.
The vaulted basement areas of this project had no previous forms of waterproofing protection and were unfit even for storage. Newton 508 Cavity Drain Membrane was mechanically fixed to all vaults with Newton NuSeal Plugs. The NuSeal Plugs were wrapped in Newton Waterseal Rope forming a waterproof seal with the membrane but also offering a secondary fixing point for the timber battens to be applied. Once the treated timber battens were applied into the heads of the NuSeal fixing plugs, plasterboard was applied to the battens.
The floor area was newly formed reinforced concrete with a rebate formed around the perimeter and around the walls built of their own foundations. A 100mm x 80mm deep channel was gunned out and the Newton Basedrain installed within the rebate. Newton 520 Cavity drain membrane was installed onto the new RC Slab and a 65mm screed applied on top.
All water that entered the building now a clear method of reaching the Newton Titan Pro Sump Pump system to be mechanically removed from the vaults. Once the Newton System 500 Cavity Drain membrane system was installed, the high quality wine rack and management system was installed to house the clients wine collection.
The wine racks and system could be installed quickly without the need for extensive drying out times as is the case with cementitious type Type A tanking systems.
The battening technique also allowed the client to mechanically fix shelving units and humidity control systems back to the battens without compromising the waterproofing system.
