e-Radication wall tanking is a slurry-applied chemical treatment
used for controlling dampness and lateral penetration of moisture.
It is a sealant composed of inorganic chemicals, finely graded
quartz sands and cement. Our operators using high pressure
spraying equipment, apply it to wall and floor surfaces under
pressure in order to seal and tank against moisture ingress.
Areas to
be treated should be totally free from dust, dirt, loose material,
plaster, bitumen, oil, paint, etc. Uneven surfaces should
be levelled and as necessary re-pointed, with a special cement/sand
mixture, which will be specified by us. This light screed
or scratch coat will level up the wall surface, it should
be allowed to cure for at least twenty-four hours before the
tanking mix is applied.
The tanking will remain
soft for about twenty-four hours, so avoid contact during
this time. Where, and if necessary, a second coat can be applied,
once the first one has begun to harden. Treated surfaces may
be rendered after forty-eight hours and will become fully
effective within eight days. It is recommended that the Client's
plastering contractor re-plaster the walls using salt inhibitor,
as per our re-plastering specification issued with every contract.
Fixing instructions can be issued if and when required.

The active ingredient of our waterproofing chemical is a specialised
e-Radication silicone. It complies with the application requirements
set out in the British Standard 3826, Part 1 - Silicone based
water repellents for masonry.
When liberally
applied by spray to the dry porous surface of masonry, the
chemical will render it fully water-repellent immediately,
as soon as the solvent has evaporated. No intermediate curing
or aging is required. A second or third application is usually
necessary.
This treatment
renders a surface water-repellent but does not seal it, and
although the vapor permeability of the substrate is slightly
lowered, a treated surface will still allow the passage of
air and water vapor.
Because the treatment
produces water repellency rather than a complete sealing of
a surface, it will not prevent the penetration of water at
pressure in excess of about 20-lbs./square inch. Penetration
will rely on the porosity of the stone or brick but the water-repellent
effect will extend well below the surface of the substrate.
A treated surface is just detectable if it is immediately
adjacent to an untreated area. In general, it can be stated
that the application of this solution causes little or no
change in the colour of the surface treated.

At the present time, when the heating of a building is of
such vital importance, insulation can play an essential part
in keeping the heat produced within the building. At e-Radication
we have found that the most important part of any building
to insulate is the roofspace. There are many advantages in
roofspace insulation, the main one being a substantial cut
in heat loss through the roof by from 60 to 70 per cent.
The e-Radication
range of fibre insulation material is completely non-combustible.
The material has been given an official spread of flame test
and is now acceptable under Government regulations. It will
not support any form of fungal, bacterial or animal life,
and will last indefinitely. It can be supplied in any size
or thickness
