ROOFING
Kemperol cures roof ailments at Poole Hospital
Kemper System’s Kemperol
2K-PUR solvent-free and
odourless waterproofing
membrane has been used to
refurbish the roof of Poole Hospital’s
outpatient department, ensuring
that the project avoided any odours
that could become a nuisance to
staff and patients in the unit or the
surrounding wards.
The cold-applied liquid
membrane was installed by
contractor, Hi Tec Roof Systems,
overlaying the existing single ply
membrane on the 480m2 roof.
Despite regular repairs to the
existing roof, the single ply
membrane had failed due to a
number of factors, including the
loosening of mechanical fixings,
damage caused by seagulls and
holes in the membrane caused by
cigarette butts discarded from
above.
The Kemperol 2K-PUR membrane
was selected for the scheme to
ensure minimum disruption at the
hospital as it is completely odourless
throughout the installation process,
required no strip out of the existing
roof substrate, no hot works and no
wait time between applications of
resin.
Explains Steve Mulcock from Hi
Tec Roof Systems: “The outpatient
department at Poole Hospital is
based around a central courtyard
and surrounded on three sides by
seven storeys containing wards. It
was vital, therefore, that we used a
system that would minimise
disruption while providing a durable
solution. The cold-applied liquid
system also helped to ensure we
could handle the awkward shapes
and details of the roof’s quadrangle
layout.”
Hi Tec Roof Systems cleaned and
prepared the roof, applying a
fungicidal wash to completely
remove any contaminants before
applying a Kempertec primer. The
Kemperol 2K-PUR resin was then
applied 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.
Finally, a non-slip maintenance
walkway was created on the
completed membrane using tiles
fabricated from recycles tyres.
Comments Richard Moremon
from Poole Hospital: “The outpatient
department’s location had made it
especially susceptible to wear and
tear and this roof refurbishment has
not only delivered a much more
robust surface but has also
addressed some of those issues,
ensuring that the new Kemperol
membrane will fulfil its expected
BBA service life of at least 25 years.”

The perfect match for roof restoration
When Surrey County
Council needed
assistance to restore the
roof of a historic
former 19th century school
infirmary which has been converted
into a busy youth centre, they
turned to the roofing expertise and
product quality on offer from
Marley Eternit.
The subsequent specification of
Marley Eternit’s handcrafted
Ashdowne clay tiles has ensured that
the newly restored roof maintains
the heritage look and feel of the
previous roof to seamlessly
complement the style of the
important building, as well as
delivering a proven roofing solution
that will perform for decades to
come.
James Bellamy from roofing
contractor, Breyer Group, who
undertook the roofing project for
the council, explains: “Marley Eternit
was approached by Surrey County
Council to carry out a roof survey at
the site in Bisley. The building had
been converted into a youth centre,
acting as an important local amenity
to allow young people to participate
in a variety of activities ranging
from football to cooking and art.
“It is not a listed building, but as
it dates back over a hundred years
the original roof was constructed
with handmade double camber clay
tiles. Unfortunately, over time, the
state of the roof deteriorated and it
has fallen into
disrepair and needed
major remedial work.
While the structure
required a new roof,
the finish also had to
be sympathetic to
the design of the
original building.”
After Marley
Eternit completed
the roofing survey
and provided
samples of the clay
tile, the decision was
taken to select
Ashdowne as the
ideal roofing product
solution to deliver
beauty, character
and warmth and
replicate the building’s original state.
James Bellamy concludes: “The
finished roof looks fantastic and is
truly in keeping with the historic
building. The Ashdowne tiles are an
ideal match for what was in situ
previously. It is very important from
an aesthetic perspective to have the
ability to offer appropriate roofing
solutions for older buildings so we
maintain the look and attractiveness
of buildings constructed long ago.
The Ashdowne clay tile has certainly
achieved this for the Bisley Youth
Centre. New tiles with an aged
appearance were required, and with
Marley Eternit’s help, this is exactly
what we got.”
The Bisley project used the
Ashdowne clay plain tile in
Aylesham Mix colours. The tile
offers a mellow appearance and
granular texture to provide slight
random irregularities, giving each
tile a unique character so every
project has its own singular and
distinctive look. The tiles also offer
excellent environmental credentials
including BES: 6001 and the BRE
Green Guide A+, together with a
complementary range of fittings and
accessories.
