Perfect Finish Coating secures over one million square
metres of waterproofi ng orders for World Expo 2020
The World Expo 2020 will be held in
Dubai, in the United Arab Emirates,
between October 20, 2020 and April
10, 2021. The Expo site, will cover
a total of 438 hectares and will be
located close to the Dubai World Central airport.
The master plan, designed by the American
fi rm HOK, is organised around a central plaza,
entitled Al Wasl (meaning “the connection”
in Arabic language). The plaza is enclosed by
three large pavilions which comprise themed
districts: opportunity, mobility and sustainability
– these form the ethos of the Expo 2020 site.
AFC was awarded a $600 million contract to
build the three main theme districts at the Dubai
Expo 2020 site, part of over $3 billion worth of
construction contracts issued in 2017.
The themed districts will house a total of
136 pavilions which will be used by participating
countries, non-governmental organisations
and commercial partners, the districts and the
buildings within them will have a fl oor area of
Perfect Finish Coatings (PFC) secured its
fi rst project on the Expo 2020 site with the
substructure waterproofi ng of the project star mall
with Laing O’Rourkes in early 2017.
PFC secured the substructure waterproofi ng
on the three themed districts, which was over

700,000m2 of bitumen felt membrane by BASF.
The company was able to secure the project

PFC has been able to successfully complete
the works on programme in under 15 months.
Daniel Van Dok, partner and general
manager of PFC, said: “The project was of
great success and showcased the capabilities
of PFC on being able to complete a job of
this colossal size, whilst still meeting a tight
programme. We had over 150 men on the
project and were installing over 2,500m2 of
membrane on a daily basis.
“We had to deliver a container of material
every other day to site, whilst working in 10
locations, some during summer months of 49
plus degree heat.
“Due to our successful completion of the
substructure waterproofing, in April 2018,
the main contractor awarded PFC the roofing
and podium waterproofing works, which
amounts to over 320,000m2 of membrane
During the last year, PFC has secured many
other projects on the expo site and has secured
orders of over 1,000,000 m2, the equivalent to
over 140 football pitches.

areas needed replacing.
Sampling also tested for moisture in the
roof, identifying both the leaks and interstitial
condensation. It was also discovered that the
metal decks were incorrectly laid, so rain water
sat in troughs causing internal rusting. Provision
was made in the tender process to cover deck
replacement or repair so there were no additional
costs to the school.
Once the metal decks were repaired, the roofi ng
contractors installed a new SIGnature metal lined
Vapour Control Layer (VCL), torch bonded to the
repaired metal deck.
Replacement membranes were required for the
roof of the combined large hall, dining room and
kitchen roof, partly pitched at 20 degrees, and that
of the smaller boiler room.
A SIGnature touch
The other two roofs in the project, over
classrooms, were overlaid with a new membrane
– SIGnature Elastomeric Torch-On System
– without the existing build-up having to be
removed. Although leaking, the roof build-up was
otherwise in good condition, so another type of
overlay became an option.
The boiler room roof had a top surface of
limestone chippings on top of two layers of
bituminous underlay. Beneath this was a fi breboard
insulation laid over a VCL; and another bituminous
membrane. The VCL was laid directly onto a
profi le metal deck providing the roof structure.
Stripping the roof away revealed water sitting in
the deck troughs, which had rusted through due to
apparent failure of the waterproof layer.
Ian Harmer, director of fi nance and corporate
services for Abbey Multi Academy Trust, which
owns and operates Lightcliffe Academy, said:
“We fi nd the approach of SIG both welcoming
and refreshing as they were always prepared to be
fl exible, looking at all times to work with the Trust
to meet our changing needs and requirements.
“They were always professional in their
approach and were very proactive in the way in
which they managed the project, much of which
was carried out in a live school environment.”
