Basement
Waterproofing
The
conversion of a damp basement or
cellar can
be a surprisingly inexpensive method
of dramatically increasing
available living space, and can also significantly
increase the value of a property.
Where
necessary we can also supply and install cavity
drainage membranes. An air gap
is formed between the water resistant membrane
and
the brickwork.
This gap enables the brickwork to effectively breathe
and this in turn balances water vapour pressure.
The membrane can be
fixed to walls and ceilings by means of easy
to fit, sealed fixing plugs.

Timber
Treatment
Building timbers which become damp and
also lack sufficient ventilation are most vulnerable
to attack from dry
rot.
Diseased wood is subsequently robbed of its natural
strength and may be reduced to a frail and brittle
condition. Once established the rot could potentially
spread through adjoining
brickwork or masonry in an effort to infect
further wood.
Unless treated quickly and effectively,
it may eventually cause severe damage.
Cavi - Tie
are able to provide swift, accurate and professional
analysis and advice on what is required to keep
expensive repairs to a minimum. This could mean
the judicial removal
of all affected timber
and wall plaster in the vicinity of the inital
rot outbreak followed by thorough sanitisation
through the use of
a
concentrated fungicidal solution.
Rising
Damp
Rising damp affects a high
proportion of established buildings in the
U.K. to some degree or another.
Walls can become damp from the foundations
upwards if a damp course has been breached
or if no damp course exists.
Rising
damp in buildings can be defined as the vertical
flow of water up through a permeable
wall structure,
the water originating from ground water. The water
rises through the pores (capillaries) in the masonry
by a process loosely termed "capilliarity." In
other words the masonry acts like a wick.

Treatment
of rising damp (known as "damp-proofing" or "dampcoursing")
typically involves the installation of a chemical
DPC using specialist injection equipment.
Firstly,
12mm diameter holes are drilled horizontally into the
mortar joint at 120mm centres and to a depth of 10
- 20 mm from the opposite face.
Secondly,
Cavi - Tie will fill the bore holes with DPC injection
cream using a cartridge gun.
Finally,
Cavi - Tie will cap the resultant holes. N.B. Salt
contaminated plasterwork should be renewed. Please
ask
for our recommended replastering specifications.
All
our Damp and Timber work is covered by our long
