HOME > SERVICES > RISING DAMP
 
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).
If left unchecked it will rot any floor joists and other interior timber it comes into contact with, culminating in the development of wet rot or dry rot.
- 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.
- Unvented 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 checmical damp proof course.
The Eradicure DPC system is introduced by the injection of a special siliconate checmical 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 the recurrence of rising damp.
