The natural choice
for green roofing
With its immense durability and outstanding green credentials, mastic
asphalt is rapidly becoming the logical choice for architects and key
specifiers looking for eco-friendly waterproofing solutions.
Its longevity has always made the material
one of the most cost-effective waterproofing
membranes of its kind and its manufacturers
are constantly striving to lessen the impact
of mastic asphalt on the environment.
Once laid, mastic asphalt promises to last
the design life of the roof, far outperforming
any other membrane on life cycle costs.
Emphasising its outstanding green credentials,
the entire mastic asphalt industry recently set a
precedent for others to follow by achieving the
CarbonZero standard – the first time a whole
industry has managed such a feat.
This means the world-beating waterproofing
solution can comfortably be specified on any
green project, safe in the knowledge it will
minimise the threat of climate change.
Perfect for roof gardens
Highly versatile, mastic asphalt can be laid
over flat, curved or sloped surfaces to offer
outstanding waterproof protection to even
the most ambitious concepts. Once laid, the
membrane promises to outlast the substrate,
often in excess of half a century. At the end of
its design life, it is totally recyclable.
Its seamless application makes it perfect for
roof gardens, paved areas and any other
situation where form must meet function. By
integrating thermal insulation measures, as a
warm roof or inverted, mastic asphalt can also
help architects hit critical U value targets.
Ponding is usually the last thing you need
on a flat roof – but there are exceptions.
With what is claimed to be the UK’s first
ever purpose built roof pond, measuring
20 square metres, mastic asphalt has
again proved its credentials as the
ultimate waterproofing membrane –
with a promise to keep shoppers at
Manchester’s Unicorn Grocery store dry

laid to the roof.
It was applied in three coats, to a total
depth of 30mm, over a glass fibre mat,
which acted as a separating membrane
to the concrete substrate. A further
three coats, with a total thickness of
20mm, were applied to all upstands.
The fully insulated roof was completed
with another isolating membrane, laid
over all mastic asphalt surfaces to the
top of soil level, and followed by 120mm
thick boards of thermal insulation on
both horizontal and vertical surfaces.
