It doesn't seem like a particularly fascinating subject, nevertheless, a quick search on the world's preferred web online search engine will reveal that in some circles rising damp is an extremely hot subject undoubtedly. The problem is that it appears that it could undoubtedly be some kind of faith or god; does it exist, or doesn't it? The truth of the matter is that rising damp does certainly exist in one kind or another, however, it is typically misdiagnosed, or you can typically spend for costly treatment that really isn't necessary.
Increasing moisture in structures may be defined as the vertical flow of water up through a permeable wall structure, the water is derived from groundwater. The water increases through the pores (blood vessels) in the masonry by a procedure loosely described as "capillarity." In other words, the masonry imitates a wick The common causes are degeneration due to age and bridging of a wet course with internal concrete floors, renders or external courses, and earth levels (a wet course is particularly designed to avoid the possibility of rising damp- it is developed of a matter of course in all new buildings).
If your house does have an issue (something we will discuss later on) then it can cause the following symptoms:
For within walls
The paint does not stick to the wall.
Wallpaper lifts and discolorations appear on the walls
Plaster flakes away feel soft and spongy, bubbles and white powder or crystals appear.
Skirting boards and flooring boards rot.
For outdoor walls.
Mortar worries and falls out in between bricks and stonework.
Spots or white powder appear on walls.
These problems are primarily visual problems just, nevertheless, it is imaginable that structural damage might arise from comprehensive increasing moist, and of course, a moist moldy environment might pose a health threat to people.
Clearly, if you have any of the above symptoms then it is possible that your house is struggling with rising damp, and it would be recommended to get a 'professional' in to take a look at your house. However, this is where you will deal with a major problem; who is a professional, and who is simply a 'cowboy' out to identify you with the "worst case of rising moist that he has ever seen, which can just be resolved with the most expensive treatment on the marketplace"? There are a lot of companies out there who have targets to meet and earnings to make, and the method they do this is by overzealous detecting, and charge you substantial charges for carrying out work that may, or might not, fix the issue.
The significant issue is that any damp-proofing salesperson that you utilize to take a look at your house will utilize an 'increasing moist meter'. These meters are supposed to measure the moisture in products, however, what they in fact do is measure the electrical conductance. The concept is that the better the conductance (the ease at which electrical energy flows) the higher the water material. However these meters can just be adjusted for one product, and that is usually timber. They will give reasonable results for wood and possibly some plasters, however for bricks, wallpaper, and concrete they will provide readings that are way too high. Thus they can be used (by unethical salesmen) to indicate that you have to rise moist "since the meters say so" when in fact you have a completely regular wall.
In summary, if you can noticeably see an issue with your wall, with apparent signs of damage due to water or salty tide marks then you may have a problem with rising moist, and you will require to look for a trusted professional to come in and take a look at your issue. Be extremely, extremely cautious of any 'specialist' who has actually been employed to do a basic study of your home, or certainly comes around providing a complimentary check-up of your building. If they take out one of these moisture meters, jab it into the wall a few times and declare that you have a significant issue, then it is entirely possible that they are a commission-based sales representative attempting to extract cash from you.
Generally, if the wall looks okay, it is fine. If it appears like it is damp, moldy, or has tide marks on it, then you have a problem with moisture, condensation, or increasing moisture in your home, and you need to examine things even more.
