waterproofing. In areas subject to moisture
exposure where additional movement can
occur, uncoupling mats can be used in
conjunction with tanking products to
ensure a combination of waterproofing
and uncoupling can be achieved. When
waterproofing or no priming of the matting
is required, such as with a waterproofed
uncoupling mat, do ensure that the
membrane and liquid coating can interface
with the chosen drain.
While the uncoupling membrane was
originally devised for the installation of
ceramic tiles, uncoupling systems are now
recommended for use when tiling natural
stone on all substrates. Importantly,
uncoupling mattings are recognised by most
floor trade associations related to the tiling
industry as a major benefit. Both the TTA
and the Stone Federation of Great Britain
recognise the value of using these products
and also gives reference to their use in
BS 5385 part 3, 4 and 5.
Non-cavity uncoupling mat systems are
perfect for use in commercial or domestic
environments, with some products actually
capable of accepting loads on floors
immediately following installation, due to
having a condensed profile with almost nocompression. This makes them perfect for
car showrooms, hospitals, and shopping
centres, areas where vehicular traffic is
present, and areas with mosaic tiles.
Relatively new to the UK market, floating
mats are loose laid onto the substrate and
as such provide ‘true’ uncoupling – similar
to the ancient use of sand as a buffer layer
between the tile and substrate.
The use of a floating uncoupling system
seriously reduced preparation time and
project cost – particularly when equipment
such as floor grinders and sanders have to
be purchased or hired in to remove any
laitance on screed which could react to the
adhesive used with bonded mat systems.
Floors often need additional priming before
accepting any cementitious tile adhesive.
Floating systems also take away the
need for the screed to be fully cured,
because any residual moisture in the
substrate is evenly distributed through a
system of channels and then drawn off
through the perforations in the mat via the
grout joints. In this way, substrates that are
still damp are not encapsulated.David Wilson is UK head of technical

Marleypulled out the stops recently to help
a customer complete a roofing project, which
included the supply of its brand new classic
red smooth acme double camber tile before it
had even launched. Marley’s Regional Sales
Director, Andrew Rooke commented: “It
became clear that a soon to be launched Marley product – a new
classic red smooth acme double camber tile – could well be the perfect
answer.” Determined to ensure the customer got the very best service,
Marley subsequently arranged that the required small quantity of the
new product from the trial run was supplied without delay.
