Damp Proofing - Rising Damp
Green Heat Installations
We at Green Heat Installations have a vast knowledge within the
construction industry. All our damp proof technicians are certified
installers and are specialists in the treatment of dampness in buildings.
We will carry out and initial survey free of charge, visually inspecting
the inside and outside of your property as well as taking damp readings
from your walls and floors using the latest technology damp meters
which use radio frequency inside your walls. We can then give you
a report based on our findings and a price for the work needed to
cure your damp problems. We
could go on for hours explaining the different types of damp and
condensation, throw in a few big latin names and confuse the hell
out of you... but we won’t.... so we will keep it simple....
Rising Damp
Moisture from ground water rises through bricks that are under ground
level. If a building has a failed damp proof course then the moisture
and ground salts will travel up the walls with considerable damage
to the internal and external brick work causing plastered walls
to deteriorate, paint to blister and wall paper to peel away from
the wall.
Penetrative Damp
This is classed as any water that finds its way inside though external
walls. There are many causes which include over flowing gutters
or damaged downspout, incorrect fitting of doors and windows, cracks
in external render, porous bricks and weathered mortar joints. Again
this can cause plastered walls to deteriorate, paint to blister
and wall paper to peel away from the wall.
Condensation
Condensation ( moist air ) is caused by two things, the way we live
in our house and poor ventilation. Moist warm air can come from
bathing, cooking, washing, drying clothes and breathing! A family
of four produces on average 65 litres of moisture a week... Warm
moist air turns in to water vapour when it reaches its dew point
usually against cold surfaces like around windows and doors also
on external walls lower down. If left untreated the condensation
can create mould growth, black mildue of fungi which can lead to
serious health problems and has been linked to asthma.
As
you can see from the picture above 35% of a buildings heat loss
is through the walls, wet cold walls not only attract condensation
but do not hold heat as much as a dry wall. Bricks have been tested
in laboratories and found that dry bricks hold heat 50% more than
wet bricks, which leads to greater heat loss through your walls
and higher energy bills!
Thankfully we have a solution for all of your damp needs.....
For the treatment of rising damp we inject your walls with Dryrod’s
invented and patented by Safeguard Europe LTD who have for thirty
years been the foremost innovators and manufacturers of damp treatment
products. The development of the patented dryrod system has taken
over three years of intensive research and the British Board Of
Agrement tests show that Dryrod outperforms competing products.
12mm grooved rods that carry a powerful water-repellent material
are inserted into pre-drilled holes along the mortar line of a building,
once diffused they cure to form a highly effective barrier to damp.
The product will remain effective against rising damp for at least
20 years. Once the affected walls have been injected, if needed,
we use Dryzone damp resistant plaster which is a modern formulation
of breathable damp and salt resistant plaster. Unlike sand and cement
renders it is not destructive to the underlying masonry and forms
a warm surface which will stop condensation forming on the areas
covered.
For the treatment of penetrating damp we use Stormdry masonry protection
cream. Stormdry is a colourless, breathable water repellent treatment
for brick, concrete and stone walls. It is able to penetrate more
deeply into masonry than traditional liquid applied repellents,
providing an effective breathable barrier BBA testing showed that
Stormdry offers 25 years protection against penetrating damp. Studies
carried out by the University of Portsmouth have shown a 29% reduction
in heating energy on houses treated with Stormdry. This fact has
been recognised by the Uk government and energy and carbon savings
have now been independently verified in a further study by Giraffe
Innovation environmental consultants, a copy of which can be found
at www.stormdry.com
Stormdry and Dryzone products are the only damp proof treatment
approved by the BBA and are the best on the market. Even though
other products are cheaper we only use the best and that’s
why all our work is backed up by a 20 year guarantee underwritten
by Specialist Building Guarantee insurance company.
Areas we cover:
Northwich, Middlewich, Winsford, Crewe, Frodsham, Runcorn, Widnes, Chester, St Helens, Liverpool, Wigan, Warrington, Leigh and Manchester.
