This prestigious hotel called on the best
The Lanesborough on Hyde Park Corner, Knightsbridge is one of the most luxurious hotels in the capital. However, this 5-star hotel was not always the haunt of royalty, the rich and famous that it is today, and in fact it began life as a hospital in 1844 before closing in the 1970s. It was eventually refurbished and reopened as a hotel in 1991.
Current owners, the Oetker Collection have carried out an extensive renovation project throughout 2014 and The Lanesborough reopened its doors in Spring 2015 as London’s finest residence.
An innovative treatment is required
Simon Johns, Peter Cox Senior Surveyor said: “We feel immensely privileged to have been asked to work on one of the finest hotels in the country and to have had a glimpse of the fabulous renovation”
According to the hotel website: the renovation has honoured the building’s architectural heritage as one of London’s most revered Regency landmarks and embodies the signature style that has become synonymous with The Lanesborough, whilst incorporating the latest in contemporary luxury and technological innovations.
Simon explains that Peter Cox was asked to provide a water proof render system on three lift pits of the hotel, two service lifts and one public lift, where water had been found. Under usual circumstances these conditions would have treated with a ‘sandwich’ render system which would see the walls being plastered, water proofed and then plastered again.
“Following a pre contract meeting with the client and lift engineers we discovered that if we used this system we would reduce the size of the pits making the existing lift gear unusable,” said Simon. “The waterproofing was just 35mm thick but it made all the difference and so we had to come up with an alternative that met the original brief but without compromising the operation of the lifts.”
Peter Cox experts redesigned the system which meant contractors had to cut a channel into all the floor/joist junctions – which is the weakest part of the lift. This then meant the Peter Cox team could apply Vandex Unimortar at the wall / floor junction, a special material that is applied in layers in one working cycle. Due to its composition, based on cement and quartz with graded grain size distribution and selected additives, it is resistant to abrasion and capable of taking strong mechanical wear.
Simon said: “Instead of the original waterproof system we applied two coats of Vandex Super Water Proof system to all walls and the floor of each pit – this was instead of the ‘sandwich’ system and saved valuable millimetres which would not compromise the operation of the lifts.”
Top notch service
Vandex Super is in-depth crystalline active waterproofing slurry specifically formulated for waterproofing concrete. The active components of Vandex Super penetrate into concrete and form insoluble crystalline complexes. These crystals block the capillaries and minor shrinkage cracks in the concrete – preventing further water ingress.
Simon adds: “This was a particularly satisfying project as Peter Cox was asked to complete the job where others had failed to deliver a service. Our expertise and knowledge meant that we were able to find a solution which played a small, but important part in the renovation of this prestigious hotel.”
