The cause of damp is often apparent from the symptoms that various types of damp present; however, this is not always the case. The “musty” scent, fungus, or damp spots that occur within the home are usually signs of damp. Condensation is the most common form of condensation found in American homes. In our homes, a lack of “breathability” and a build-up of water vapour not only causes rot, damp, and structural collapse, but it also contributes to sick building syndrome. It’s also been attributed to an increase in asthma and allergies. Rising Damp – In a nutshell, this is water absorbed from the ground by capillary action. It is only a concern if a building lacks a Damp Proof Course (D.P.C), as is typical in older buildings (pre-1930), or if the D.P.C is bridged or impaired. Due to gravity and capillary powers, rising damp only rises about 1 metre above ground level. The most common treatment for rising damp is to inject a chemical D.P.C. This may be required in a variety of areas and may be required both internally and externally on occasion.Do you want to learn more? view here
The guarantee duration for this form of job varies, but it is typically between 20 and 30 years. Water entering through the roof or walls is known as penetrating damp. Water spills into a structure due to a flaw, such as around a chimney stack or windows. Missing roof tiles or a lack of mortar between brick courses are examples of this. Check for leaking or missing drainpipes, which can cause water to soak all the way through the wall. Internally, this form of problem is often revealed by the presence of isolated damp patches. How do I get rid of penetrating damp? – In some situations, these internal problems can be solved by making necessary external fixes, such as re-pointing. Internally, however, if this issue becomes more common, it will result in higher moisture content in plaster work, decorative finishes, and the home as a whole. This will necessitate a more long-term approach.
