Three roofs of one of Manchester’s most
iconic office buildings have been refurbished with an overlay of
Kemperol liquid membranes from Kemper System.
Piccadilly Gate is home to various
Government departments including Education, Ofsted and Highways
England.
The 125,000sqft building adjacent to
Manchester Piccadilly Station was refurbished in a £25 million
BREEAM ‘Excellent’ scheme in 2010. Issues with the integrity of
the roof had continually plagued the building with leaks, resulting
in unsightly staining to the suspended ceilings within. Consequently,
the decision was taken to overlay the existing single ply roofing
membranes on levels 10, 4 and 3 with a cold-applied liquid system
from Kemper System.
Roofing contractor, Castle Roofing, was
appointed to carry out the works and selected Kemper System’s
solvent-free Kemperol 2K-PUR as the most appropriate solution for the
level 10 roof.
Explains Mark Atherton from Castle Roofing:
“The level 10 roof is directly above occupied office areas and is
also the location for the building’s air handling plant, so
nuisance odours could potentially have been transferred into the
office areas.
“As a result, we chose to use Kemper
System’s 2K-PUR system, which is solvent-free and odourless, while
still offering high performance and a BBA-accredited 25-year service
life.”
The
level 4 roof is above the building’s record-breaking extra-long
escalators and leaks from two water outlets had caused staining of
the suspended ceiling. This roof was also refurbished as an overlay
system, using Kemper System’s Kemperol V210.
Having
cleaned and prepared the existing roof surface, Castle Contractors
applied a primer before applying the resin in a single wet-on-wet
process in which the resin is first applied to the substrate;
reinforcement fleece is then laid directly on to the wet resin,
immediately followed by more resin on top.
This
ensures complete saturation of the reinforcement fleece. Once cured,
the resin forms a seamless, elastomeric waterproof membrane that
cannot delaminate, is UV stable and bonds directly to the substrate.
For the green roof on level 3, Castle
Roofing carried out the refurbishment in two sections, removing half
the green roof medium and installing Kemperol V210 onto to the
existing surface as an overlay before replacing it and lifting the
second section so that the new roofing membrane could be installed.
The second section was then re-instated, completing the programme.
Comments Jim Fozzard, building manager at
Piccadilly Gate: “We needed a roofing system that could be
installed quickly to prevent any further damage to the building’s
interior, while minimising any disruption to occupiers and
maintaining Piccadilly Gate’s high aesthetic standards.
“Using Kemperol 2K-PUR on the level 10
roof meant that occupiers were not affected by any changes to air
quality, while all three roofs have been overlaid using a seamless
membrane without the use of hot works for a durable solution
requiring no strip out.”
