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. The salt cristals shrink in size during the day as they are dried by domestic heating or the sun. At night as the the temprature drops, humidity usually rise and the salts absorb water from within the walls and from the air, causing the them to expand. This process is the reason that damp homes often have loose 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.
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.
