Rising Damp
Any masonry structure unprotected by a properly installed
Damp Proof Course is prey to rising damp. Moisture will rise by
capillary action (a suction phenomenon arising at the boundary
between moisture and a small tube, crack or other tiny, enclosed
passageway) through the pores of the masonry, seeking a means of
evaporation. The moisture will continue to rise until it reaches a
height, where unless no evaporation is possible, gravity takes over
and pulls it down again. This height is seldom more than 1.20m.
However, it is often misdiagnosed by unscrupulous or inexperienced
builders. Make sure the problem is not – for example - leaking
guttering, faulty or leaking plumbing or condensation caused by
inadequate ventilation.
Tanking
Lateral penetrating damp in below ground situations can be resolved
for both old properties and new buildings using Sovereign Hey’di
Tanking Systems. Both Hey’di K11 and Hey’di Special Systems have
been proved highly effective against extreme water pressures
throughout the world.
On new builds consideration should be given to the possibility of
any future defects and the feasibility of external rectification.
Incorporating external drainage to permanently remove any head of
water is recommended at the design stage.
Tanking systems are applied to ether the positive pressure side or
the negative side of a substrate. Positive tanking pressure is
achieved when the hydrostatic water pressure is pushing the tanking
onto the substrate. Negative tanking pressure is where the tanking
system is applied to the other side of a wall and the hydrostatic
water pressure will try to push the tanking off the substrate.
Successful tanking on the
negative side is difficult and requires a more comprehensive
specification.
When tanking existing basements internally then products such as
asphalt, self adhesive membranes or liquid applied membranes all
require a supporting vertical brick or block work lining wall, which
is normally backfilled with sand/cement mix and a minimum 50mm
sand/cement floor screed. Such systems incur space penalties unlike
the Sovereign System, which can be applied direct to the substrate
with a final thickness of less than 5mm without the
necessity of a supporting backfilled
wall. The treatment can be applied to both walls and floors.
Tanking is the creation of a watertight envelope. If there is
hydrostatic water pressure present or possible high water table in
the future, then the floor must also be tanked to complete the
watertight integrity.
If continuity is not achieved, or where different systems cannot be
tied effectively together, then the system will remain vulnerable to
possible water ingress.
Where
continuity has not been achieved, e.g., for commercial reasons at
the client’s instruction, then this should be unambiguously
identified for future reference. We would recommend identifying such
areas as ‘sectional tanking’ with liability restricted to those
areas actually tanked.
Information on the SOVEREIGN Protection Scheme AC Plastering offer
on our work.
SOVEREIGN is the market leader in the field of chemical damp proof
coursing treatments.
This reputation has been gained for the quality of its products and
also for the support and care offered under the Sovereign Protection
Scheme Guarantee. Since 1976 over half a million satisfied property
owners are testimony to the effectiveness of the Scheme.
Sovereign Protection Scheme Guarantees are used by Local
Authorities, Housing Associations, Building Societies and Banks, as
well as many thousands of householders.
Flexibility is available with the choice of 10, 20 or 30 year
Protection Scheme Guarantees for timber and damp proof courses and
the introduction of a 10 year Guarantee for façade treatment.
Sovereign Protection Scheme Guarantees are offered by AC Plastering
Services Ltd who have been vetted by Sovereign. Only when Sovereign
are satisfied that we are capable of carrying out work to a
consistently high standard do they allow us as contractors to apply
to become Sovereign Approved Contractors. Regular site visits ensure
that standards of workmanship and customer care are maintained.
Sovereign even believe that even the most conscientious and
meticulous contractor may not be available to service his
guarantee due to circumstances beyond his control. In this
event Sovereign intervene.
Once the Sovereign Protection Scheme Guarantee has been issued the
property is covered against a recurrence of the original problem for
the full term of the Guarantee.
This cover is initially supplied by the AC Plastering, however, if
we were no longer in business, Sovereign will arrange for the
necessary re-treatment to be carried out by another Sovereign
Approved Contractor.
All work will be completed to Sovereign Specifications at all times.
