FREQUENTLY ASKED QUESTIONS FROM OUR CLIENTS:

What is ELECTROOSMOSIS?

Electroosmosis – an osmosis that involves the onset of flow due to the application of an external electric field. It depends on the shape and the sort of the closed system. It is the motion of polar liquid through a membrane or other porous structure. Electric fields cause migration of ionic species, and the mass transport is further affected by diffusion and convective flow. Ion transport can in turn drag solvent species along, which affects the system's fluid dynamics and the electric field.

What is a capillary damp?

Old buildings' walls usually don't have any insulation, neither vertical nor horizontal, and if they do, it often needs fixing. This problem concerns also some new buildings, due to construction problems that lead to repeated walls damp. The vertical and horizontal insulation prevents the walls from absorbing water from the ground. If the insulation needs fixing (or there's no insulation at all), the water enters into the porous structure of material. The number of the capillaries depends on the material, for example, the capillaries can make up to 25% of brick's weight. As a consequence, in case of contact with water, the wall becomes like "a sponge" absorbing the water. This phenomenon is called capillary damp.

What are the alternative methods to remove the capillary damp?

Some popular ways:

Damp proofing injection – putting the chemicals into the holes made in the walls (each of 10-15 cm); the substances are being absorbed by walls and create the insulation. The most important disadvantage of this method is a difficulty to generate a perfect insulation, especially if the walls are very humid and thick. If the level of the damp is important, the capillaries are usually filled with water and there's no possibility to put the chemicals into them. Moreover, there is no guarantee of such an insulation, and it does not include any pre-drainage.

Cutting damp – cutting foundations:

a). Putting in stainless brass (e.i. corrugated iron), using an air-drill (up to 40 cm of thickness) or a percussive hammer.

b. Cutting brick walls manually, by forging the bricks (up to 60 cm).

c) Mechanical cutting (horizontal cutting of the wall, by using a saw, or an electric chainsaw, or a liquid with quartz sand under the pressure of 35 MPa.).

Each of above described methods involve a lot of works, and, as a consequence, a huge cost.

Furthermore, if there are problems with the horizontal insulation, we must cut all the inside walls, too. As a consequence, we have to be careful because of all the installations in the building (gas, water). Additionally, this method is limited: if there are stones in the wall that we want to cut, the cost of all the operation increases; if there are metal elements – it will be impossible to proceed at all.

All the above mentioned methods have some other disadvantages. The injections and the cutting don't actually dry up the building – we just cut off the water source, and keep the humidity that already exists inside the walls. Moisture will disappear naturally, but it takes time and does not protect the building from mould and fusty smell. In addition to this, all those methods are invasive (there is a mechanical interference in the structure of walls), which influences the stability of the building, and also requires a lot of fixing and repairing.

Why is the cordless elecroosmosis worth choosing?

The cordless electroosmosis system dries up the walls and after that, there is no possibility of renewed dump (the capillaries are being closed so that the insulation is created and "replaced"). Additionally, this method is far less expensive than the traditional methods.

How can the cordless electroosmosis system replace the insulation?

The cordless electroosmosis system, emitting the electromagnetic waves of a suitable form, intensity and frequency, regularly pushes the water from the walls into the ground and makes the capillary damp impossible.

What is the price of the devices?

The number and the price of the devices necessary for your building's drainage, is established individually by our consultant after a professional evaluation of: the size of the building/room, thickness of the walls, humidity level, salinity, materials, etc. We prepare a special evaluation document on your request.

Is the electroosmosis system safe for people and animals?

Yes. The analyses and the Hygiene Certificate prove that the system has no harmful influence on people's health and environment (despite the electric field).

Can the electroosmosis system dry up the walls under the ground?

The system dries up the walls to the ground level. The effectiveness of the drainage of the outside walls depends on local circumstances, e.i. the level of underground water, the thickness of the walls, the materials, the insulation, etc. The inside walls of cellars are being dried up without any vertical insulation, if there is no hydrostatic pressure.
