Case Study - Central Middlesex Hospital
- Client: Bouygues/Brent Hospital Trust
- Location: Park Royal
The Private Finance Initiative (PFI) was introduced in 1993 by the
Conservatives, the aim of which was to encourage private
investment in major public buildings. Since PFI began, 27 new
acute hospitals have been completed and 41 are due to open by
2013. One of these is Central Middlesex Hospital.
Building of Central Middlesex Hospital began in mid 2004 for
completion in early 2006. The huge building required an inverted
roof system that performed to the criteria requested by both the PFI
contractor and the client, gave all the relevant guarantees and was
still cost effective.
Liquid Plastics' seamless, cold applied Inverted Roof System was
specified. This consists of a Decothane waterproof layer, which is
guaranteed to last for at least 20 years, 120mm insulation and a
Liquid Plastics' Filtration Layer. The system can then be overlaid
with pavers to create durable walkways.
As the system is completely cold applied, this eliminates the risk of
fire normally associated with traditional roof applications.
Furthermore, because the waterproof layer is completely seamless
it is free from potentially weak areas such as joints where early
failure can occur. This is particularly important in inverted roof
situations where the waterproof layer is below the surface and not
easily reachable should problems occur.
