The large-scale basement project consists of a 4-storey deep basement located close to the River Thames in Central London.  The proposed subterranean space would offer multiple usage.

This complex project required a waterproofing design which is, able to cope with intermittent/regular hydrostatic pressures created not just by groundwater, but also geographical tidal impacts from the river Thames and potential stress challenges caused by the surrounding infrastructure such as heavily trafficked railway lines in the development’s vicinity.

The scope of the project was to provide a waterproofing solution to a luxurious lake side home.  The new build property will sit within close vicinity of a 400 ft lake.

The property itself being new build, was constructed from a Type B, waterproof reinforced concrete to provide a first form of waterproofing protection, with both Type C, and Type A, waterproofing solutions being incorporated to the structure to provide two forms of protection.  

Delta Registered Installers, South West based, Cannon Clarke Ltd were approached by the main contractor to assist with specifying and installation of suitable waterproofing solution for a pre-formed concrete swimming pool for a residential development.

The main contractor previously had used a render system for waterproofing swimming pools, but on this occasion couldn’t, because of thickness issues. The solution was required to be “flat and true”. The render system previously used would have surpassed the allowed thickness which would have impacted on the tiling process. Tiles are typically installed in swimming pools onto renders and screeds.

The scope of the project was to facilitate a combined waterproofing solution for a 2,000m² luxurious subterranean space which includes a double-level basement that will accommodate a cinema room, spa wing and swimming pool, changing, and screening rooms, servery, storage & laundry wing, plant rooms and other accommodation.

Delta Registered Installers, Knowles were appointed as principal contractor to collaborate with the architects to fulfill the role of Waterproofing Design Specialists in providing a reliable, watertight solution for this £100m project.
