Project Focus: Liquid Roofing<br />
A HIGH-FLYING ROOF REFURB<br />
Victoria Ramwell, of Kemper System, discusses the specification and installation<br />
challenges of an intricate roof refurbishment next to Manchester Airport.<br />
The location, access and roof design of a<br />
building during any refurbishment is taken<br />
into consideration during the planning<br />
stages of all projects – but even more so when it<br />
comes to a live, airport environment.<br />
A recent project which presented such challenges<br />
was the Radisson Blu hotel, which is located<br />
within a short walking distance of Manchester<br />
Airport. The building’s 2,800m² roof had proven<br />
problematic for a number of years resulting in<br />
persistent water ingress into a number of the<br />
‘Premium’ guestrooms and corridor areas on the<br />
top floor of the hotel. This meant the project was<br />
time critical to prevent any further issues as well<br />
as potential loss of profit for retailers.<br />
Liquid specification<br />
The height of the building<br />
coupled with its location and<br />
the roof design presented<br />
many challenges for Castle<br />
Contractors NW, who were<br />
awarded the contract to<br />
undertake the roof refurbishment in conjunction<br />
with the architect’s specification.<br />
The cold-applied liquid Kemperol 2K-PUR<br />
waterproofing from Kemper System – which is<br />
solvent free and odourless – was specified and<br />
allowed the installation to progress with minimal<br />
disruption to the day-to-day activities of this busy<br />
commercial hotel, as well as the adjacent<br />
Manchester Airport Terminal 2<br />
building.<br />
Overcoming on-site<br />
challenges<br />
The first challenge was to<br />
remove 2,200 concrete flags<br />
from the roof, each 50mm<br />
thick and weighing approximately 40kg. The flags<br />
covered approximately 40% of the total roof area<br />
and had been used to help prevent the original<br />
EPDM rubber roof covering from lifting in high<br />
winds.<br />
To remove these paving slabs and with Manchester<br />
