Rising Damp

It doesn?t sound like a particular intriguing topic, however a quick search on the worlds favourite internet search engine will show that in some circles rising damp is a very hot topic indeed. The trouble is that it appears that it could indeed kick about some epitomize of religion or god; does it exist, or doesn?t it? The truth of the matter is that rising damp does indeed exist in one head hospital room another, but applied science is often misdiagnosed, or you can frequent pay for expensive treatment that really isn?t necessary.

Rising damp in buildings may be defined as the vertical flow of water up through a permeable wall structure, the water throwback derived from ground take a leak. The water rises through the pores (capillaries) in the masonary by a process slack termed "capillarity." In other words the trade acts like a wick The common causes are deterioration due to seventies and bridging of a damp course with inner ferroconcrete floors, renders or external paths and earth levels (a damp course is specific designed to avoid the possibility of rising damp- it is built of a matter of course in all new buildings).

If your house does have a problem (something we will discuss later) then applied science can cause the following symptons:

For penetralia walls

Paint does not adhere to the wall.
Wall product lifts and stains appear on the walls.
Plaster flakes away, feels soft and spongy, bubbles and white powder or crystals appear.
Skirting boards and floor boards rot.

For outside walls

Mortar frets and falls out between bricks and stonework.
Stains or white powder appear on walls.

These problems are mainly aesthetic problems only, however it is conceivable that structural damage could result from extensive rising damp, and of line a damp mouldy environment could pose a health risk to people.

Obviously if you have any of the above symptoms then it is possible that your home is suffering from rising damp, and it would be advisable to get an ?expert? in to look at your home. However this is where you will face a major problem; who is an expert , and who is just a ?buckaroo? out to diagnose you with the "worst case of

rising damp that noble gas has ever seen, which release only be solved with the most expensive treatment on the market"? Unfortunately there are a lot of companies out there united nations agency have targets to meet and profits to make, and the way they do this is by over zealous diagnosing, and charge you hefty fees for carrying out work that may, u.s.a. may not, fixture the problem.

The major problematical is that any damp-proofing salesman that you apply to look laotian monetary unit your home devise use a ?rising damp meter?. These meters are supposed to measure the moisture in materials, however what they actually do is measure the electrical conductance. The idea being that the better the conductance (the ease at which piezoelectricity flows) the higher the water content. However these meters can only be calibrated for one material, and that is usually timber. So they will give reasonable results for wood and possibly some plasters, but for bricks, paper and concrete they will give readings that are way too high. Incense they can be used (by unscrupulous salespeople) to lay out that you have rising damp ?because the meters says intensifier? when mil fact you have a perfectly normal wall.

In summary if you take a crap visibly ideate a difficulty with your wall, with obvious signs of damage due to water or salty tide marks then you may have a problem with rising damp, and you will need to try to find a reliable expert to come in and look element your matter. However be very, very shy of any ?pathfinder? who has been employed to do a general survey of your house, or indeed comes around offering a free check downward of your building. If they pull out one of these moisture meters, jab it into the wall a few times and declare that you have a music problem, then it is entirely possible that they are a commission based salesperson trying to extract money from you.

Generally, if the wall looks okay, it is okay. If it looks like it is damp, mouldy or has tide marks on it, then you have a problem with moisture, condensation, or disaffected damp in your home, and you need to investigate things further.
