Here at electro-os (Damp Proofing Spain) we are continuing with our commitment to the environment, our electro osmotic systems are totally free of chemicals.

Spanish houses

Are the walls in your house in Spain suffering from the effects of damp? Have you bought an older property in Spain with plaster coming off the walls and the paint peeling? Is your house cold? Are you beginning to notice damp in your new house after only three or four years? Do you need help in resolving the issue of rising damp in Spain?

Spanish building methods

Looking at Spanish houses both old and new it is apparent that the building materials vary greatly, from piedra y barro (stones and mud), to modern ladrillo (biscuit fired ceramic bricks). In some older homes there may be a mixture of all of these materials and more, as some of the older houses were not so much built as “grew over a period of many years”. This makes the problem worse and treatment of rising damp more difficult as injection systems as efficient as they are back home, run into some problems here, due to the often lack of information about the structure and materials used during the "growth" of the house . in many houses the fact that the floors of the buildings are laid directly on the ground make elecro osmosis the only way to deal with the problem without having to almost demolish and rebuild your home.

How do we fix the problem?

Electro Osmotic rising damp and desalination treatment

Using the technology known as Electro-osmotic damp proofing a small voltage is applied between two electrodes. A series of platinum plated anodes are placed in the wall to be damp proofed. These are connected via a small power supply to an earthed conductor. The process forces the water in the walls to be drawn towards the cathode (the earthed conductor) and prevents more water from rising through the walls. The water as it withdraws from the structure carries with it the majority of the salts deposited within the structure during the active damp "sweating", that occurs normally from the walls and in severe cases from the floors. The salts or "salitre" deposited inside the walls are what cause the biggest problem, i.e. the paint and in more extreme cases the Yeso, cement or even tiles or stone cladding.falling and floors lifting due to the destructive effects of the deposited salts.

These salts apart from being corrosive (not good if your home has a steel reinforced concrete structure) act like frost and ice do in the UK. The salts deposited within the walls shrink when conditions are drier allowing more salts to come out of the walls and swell when conditions are more humid, normally at night, causing the wall covering to “blow” and become loose.
Some systems, injection for example, can stop water from rising up the walls but have no effect on the salts already within the walls and if not installed below floor level (as we do in the UK), prevent the water which normally escapes through the walls to build up under the floor causing the floor tiles to lift and the build up of unpleasant smells within your home.
Another error made usually during renovation of older buildings is installing an under floor membrane, often plastic or tar based sheet, to prevent damp rising through the floors. If the water cannot escape through the floors it will look for another way out and usually the only way out left is through the walls. A house with 100mtr2 floor area will have approx 10mts2 of wall area. The water that used to evaporate through 100mts2 now has to escape through 10mts2, causing the rising damp problem to be 10 times worse than before the reform. We have seen many homes where the owners cannot understand why after a very expensive and time consuming reform using all the best materials and builders available their beautiful home is wet, smelly and decaying at a speed they cannot understand.

All the problems listed above are easily dealt with using our system

Due to the ease of installation, the system can be installed from either side of the walls and normally requires two to three days to complete. Disruption is minimal.

What is Electro osmosis?

Electro-osmosis is a process that has a history of almost two hundred years. Discovered in the early18th century by a German scientist, it was discovered that water was moved from a positive anode to a negative cathode when a current was applied. The current, (for the boffins), used by our systems is approx 5-10volts and 20mA. Annual consumption is usually less than 1KWH costing less than 10 cents.

Electro-osmotic damp proofing systems do not affect pacemakers, mobile phones or any household electrical appliances. Being totally free of all chemicals, they are also ecologically friendly. The total lack of toxic, or in fact any chemicals, means that the possibility of an animal, pet or worse a child, suffering from chemical poisoning, can never exist.

The end result of a treated house is a greener more comfortable home that requires far less maintenance, (one ton of carbon dioxide gas is released into the atmosphere for every ton of Portland cement manufactured) and less heating (Butane: 1 bottle produces approx 26kg CO2). The problem of black mould is also endemic in most properties that suffer damp problems. This can result in a serious health risk. This infamous mould is a contributing factor to illnesses such as asthma and bronchitis. According to the CDC (Centre of Disease Control), this mould is responsible for aggravating over "100 kinds of lung disorder." All electro-osmotic damp proofing systems supplied and installed by Electro-Os (Damp Proofing Spain) consists of industrial grade titanium wire with platinum plated anodes. These systems have been installed in over 90,000 properties worldwide over the last 40 years and as the materials are virtually indestructible all installations carry a 30-year guarantee.

What does it cost?

Because the system is so quick and easy to install this is reflected in the price The price for walls up to 1 meter thick is 50€ per linear meter, so to work out a quote simply measure the perimeter of the building plus nternal support walls and multiply by 50€ to give you a price.

Electro-Os (Damp Proofing Spain) is situated in Castell de Ferro, in the province of Granada. It is a British company owned by people who have worked in Spain for twenty years. Specializing in the treatment of damp so often found in Spanish homes, particularly older, village houses since 1995. Electro-Os (Damp Proofing Spain) can treat your home to maximum effect with minimal disruption. The system works on all types of properties, irrespective of age or structure type. It is immediately effective. It permanently guards against the dangers of rising damp, and is guaranteed for 30 years.

Although based in Granada, Electro-Os (Damp Proofing Spain) will travel throughout Spain. Our multi-lingual staff are always available to help and a written quotation can be provided.

Advice is always available. Our experience of 20 years in spain working with the local builders, arquitects and of course the materials used in construction here we believe is a valuable resource to be used by all, so if you have problems give us a call for free and informed advice.
