Platon P20 Installed
A further update on this major project: The ground workers are now down to level -5 and are nearly ready for the next phase of waterproofing – using Type A and Type C waterproofing systems from Triton.
Ground workers have reached level -5
Down at level -5 and ready to install Type A & C waterproofing systems
We started to report on this major central London project earlier this year (see further down page). It’s a ‘top down’ construction which will eventually comprise five storeys below ground. A further two buildings are planned alongside each with three storey basements. Triton will eventually be supplying 9,500 m2 of Platon P20 cavity drain membrane which are being applied throughout to walls and floor slabs.
To date TT Super and TT Vapour Membrane has been applied to all wall/floor junctions of all earth retaining elevations to the intermediate levels, to reduce the associated risk of water ingress at these critical junctions. The same approach will be used as the lower levels are excavated and constructed.
June 2013:
Triton is supplying concrete waterproofing systems to a major multi-level basement project in central London.
Multi-level basement construction in progress
The basement construction is secant piled walls with BS 8007 concrete reinforced liner walls and slabs.
Triton has so far supplied approximately 9,000 metres of TT Waterstop (a ready to use pre-formed waterstop which swells up to 400%) and TT Swellmastic (a hydro-reactive expansion sealant) to all construction joints within the BS 8007 structure.
TT Admix, an ‘active’ concrete waterproofing admix has been incorporated to waterproof certain twin walls and Triton Colflex, a ready to use Hypalon jointing strip, has been installed to movement joints. Colflex detailing TT057-1(1)
Following construction, Triton will be supplying approximately 9,500 m2 cavity drain membranes to the site.
