Description

The works comprise the refurbishment and waterproofing of the existing sub-basement areas, including associated builders' works, drainage, mechanical, and electrical installations. The purpose of the project is to provide a fully tanked, dry, and serviceable environment suitable for long-term operational use within a high-security, heritage-listed building.
The scope includes (but is not limited to):
Careful strip-out and preparation of existing finishes to expose the underlying structure.
Installation of a proprietary cavity drain and damp proof membrane system to walls and floors, complete with fixings, plugs, drainage channels, and connection to existing sump pits.
Cleaning and re-commissioning of sump pits, including the supply and installation of new submersible sump pumps, float sensors, discharge pipework, and a new control panel interfaced with the Building Management System (BMS).
Application of cementitious or resin-based tanking to identified areas, in accordance with manufacturer's data sheets and relevant British Standards (e.g. BS 8102:2022 - Protection of Below Ground Structures Against Water Ingress).
Formation of new internal partitions, raised access flooring, ceilings, joinery, and decorations as required to reinstate the area following waterproofing works.
Adjustment, modification, or reinstatement of existing building services affected by the works, including power, lighting, fire detection, and PAVA systems.
Coordination with the Landlord's Facilities Management team and other ongoing building operations to ensure secure access, minimal disruption, and full compliance with Canada House site protocols.
