The evidence of rising damp is usually
found by the signs of a damp line appearing on the inside
wall. The result of this rising damp is damage to interior
plaster and wall coverings. It should also be noted
that recent findings by the asthma foundation concluded
that damp rooms can increase the risk of developing
asthma.

Rising damp occurs when water is
allowed to rise vertically through walls by capillary
action and is caused by the breakdown of, bridging of,
or non existence of, a damp proof course (DPC).
|
|
|
Other Causes of damp ingress are:
|
| - Blocked or defective guttering system |
| - High ground levels bridging the DPC |
| - Defective pointing |
| - Faulty flashing on roofs or extensions |
| - Missing roof tiles or slates |
| - Mortar bridging cavity walls |
| - Defective window sills |
| - Un-vented chimney where a fireplace has been blocked
in |

In the case of the absence or failure
of an existing damp proof course one of the simplest
ways, and hence least disruptive ways, of reintroducing
a new damp proof course without major building works,
is the introduction of a chemical damp proof course.

The Cedarcare DPC system is introduced
by the injection of a special siliconate chemical into
a series of bore holes made along the length of the
walls requiring treatment.
|
|
|
Once the treatment has infused into
the fabric of the walls and is allowed to cure, it then
forms an effective barrier against any future possibility
of recurrence of rising damp.

The current system we adopt is:

| - Siliconate injection |
