Does anybody have a sure-fire remedy for getting rid of dampness on internal walls.?

The Cypriots, along with others in Turkey do not include a DPC ( damp proof course ) in the construction of houses here.

I've heard of people who have had remedial work done by a UK registered company which has cost up to £10,000 and the dampness has returned even after a few months. Any ideas out there?

There was a thread on this recently titled... 'cyprus rust'



You could have a look through that.

Hi Bernie

Please email info@surecyprus.com, they guarantee the damp will not return on the areas treated. The internal damp needs to be treated from the outside first. Give Yasin a call, he has plenty of experience. Yasin 0533 855 5658

Website http://www.surecyprus.com - see the section on damp.

Good luck!

Please read my husbands posting message 11, be careful of anybody selling miracle cures for damp, we had to excavate to find the cause, treating the symptoms of damp on walls is not a long term solution, and yes to do the job properly will cost thousands.

Rowlo

Makes sense to me usually no need for all the expense. The word "Damp" scares a lot of people when a lot of the time its condensation due to lack of ventilation or put in a couple of air bricks to allow the building to breathe.

E-mail me your contact details and a list of your services when you get chance.

IMHO, No point in trying to fix a damp problem when its damp weather as what ever you use wont key properly to a damp wall. Do it in the summer. Paint the house, seal the teraces, mastic where the outside scirting board meets the terace, mastic any screws that are in the bottom of the patio doors etc... Probably wont cure it but will help.

I think we had a lively discussion on this subject a few years ago on bogaz info site. Its all due to dampness coming up and can affect the inside and the outside walls up to about one metre high. The water rises upwards due to what is known as "capillary effect" in physics and the effect of gravity versus capillary cancel each other out at one metre high, hence it cannot rise any more.

So no solution will work unless you cut out the water moving upwards. Normally the builders use bitumen paper under the walls at floor level to stop the water rising. This is what we did with my house 20 years ago and I did not have such a problem except where I had balconies, verandas and so on. We found out that when it rains the water seeps through the fillings between the floor tiles and through the skirting starts moving upwards on the walls. We had to remove the tiles and seal the floor up to one meter wide around the walls and then retile the floors. That cost me some money because the other half wanted good quality marbles instead of the old cheap stuff.

So ladies, this is your chance to go for better quality

Rowlo, see you are a joiner by trade..... who exactly are the "fly by nights" and "idiots"?

Sure is a fully registered TRNC company with years of experience dealing in these matters, many happy customers living in damp free properties. Good luck with your company.

I read somewhere that you can insert small electrodes into the wall just above the ground at regular intervals and then apply say -12 volts dc to repel the water. The more technical people will know that water (H2O) splits into (H) and (OH) ions and the negative electrodes in the wall repels the similarly negative (OH) ions and thus keeps the wall free from dampness.

It should work but I have not tried it.

There are products on the market that are white/brown/aluminum colored strips that after drilling larger holes in either the top or bottom of aluminum window frames can be fitted over the holes. These strips are a sliding design that can be left open allowing a small amount of air circulation that helps reduce damp. They can also be purchased with a mesh fitting inside to reduce the chances of bugs entering. I haven’t seen them around in any of the Yapi markets but some of the window manufactures may stock them. If not, bring a few over from the UK if you are based there, care of B&Q or similar outlets. They are a couple of quid each and take minutes to fit.

Hi Ismet,



We had the system you are referring to in msg 18 put in to a property in England 10 years ago. It is called electro osmosis. It is as good as any other system but a little more expensive than the usual silicone barrier injection type. My frined who lives in Tenerife had it installed about 5 years ago and she has reported 85% success.

elko,



sounds like you are referring to Osmosis, my daughter had this treatment done to her old house in uk, worked brilliantly. Not aware of anyone here doing this treatment though.

Msg 16 Elko I was always led to believe that damp rising up the wall was caused by atmospheric pressure, ie, at sea level we have 1 bar of pressure (14.7psi) this is what causes the damp to rise to about 1 metre. In most cases the damp is caused by the terraces, if you have these sealed every year at the end of September or begining of October this should eleviate your damp problems.

Hutch (msg. 24),

I am afraid the atmospheric pressure plays no part in this. You have the atmospheric pressure all over the wall, hence there is no way it can push up the damp upwards.

If you put one end of a glass tube into water and you vacuum the air from the other end i.e. if you remove the atmospheric pressure from the other end, then the water will be pushed up to about ten metres by the atmospheric pressure. In case of mercury which is much heavier than water, it rises only 760 mm.

The capillary effect is something different.

Msgs. 22 and 23,

I googled Electro Osmosis and you are right. However in my view it is a bad choice because osmosis is not involved in this process at all. I rather call it electro damp proofing.

The principle of osmosis is this: if you have two solutions, one denser than the other separated with a thin membrane (potatoes are used in schools for this demonstration), the molecules move faster in the lighter solution because there are fewer obstacles or objects for collisions. So molecules from both sides hit the membrane but the lighter solution side hit the membrane with faster molecules and thus have a greater impact on the membrane and hence as a net result more water flows from the lighter solution to the denser one. In time the density of the two solutions equal each other.

just for completeness. Reverse Osmosis is used in water distillation i.e. great pressure is applied to the denser side and thus more water passes the membrane towards the clean water side. In other words under pressure it works in reverse.

Thanks to all of you for your advice on damp, your experiences and the remedies. I am currently undertaking a lot of research into this before I make a decision on a course of action.

Bernie,

Suffering badly from rising damp throughout my new house, I had all my floors excavated, removing tiles, wet sand cement etc inside, and down to the foundation pillars outside; and found some very interesting things about the way they build houses out here. I also have a full set of photographs of the cause and effect.



Contact me off the board if you want a chat about the remedy and what it really costs to have the job done properly rather than patching over the symptoms on the walls, only to have them (as my neighbour has found out) reappear again.



best regards

There are no miracle cures..they only hide the problem..electrolosi.....usins low voiltage and titaniuom wire..i.reverse ommosis is used in uk on old buildings works... chemical injections...and as described earlier dig it out and re do probably most reliable...single course blocks dont help either...N Norman

Cleared my loose plaster off 15 months ago, keep removing new loose deposit with brush at intervals , leave exposed to breathe as it takes ages to leech out the salts , ventilate the villa and put wall units and ornaments in front of damaged area to hide it , job done !
