Physics tells us that in order for water molecules to rise by capillarity through the walls, all their negative poles must be oriented upwards or in the direction of the capillary.

The principle of electro-physical drying consists of sending electromagnetic waves. The waves disperse the molecules of the water that are rising through the walls, rejecting them, and gravity forces the water back down below the foundations of the building.

Obviously, the better the transmission of these electromagnetic waves inside the walls and floors, the more efficient the drying system will be.

Optimizing the waves transmission

With a frequency spectrometer we analyzed the transmission of waves through the walls which lead us to choose the transmission that showed maximum efficiency—that of sound frequencies.

The transmission of sound frequency through walls and wet floors is 12 times better than transmission through the air.

Additionally, we found that these waves are transmitted better by thick walls than by thin partitions, which leads us to choose the place of installation of the equipment in a thick, wet wall close to the ground.

Normally it should be placed 20 to 50cm from the floor to avoid damage when sweeping or vacuuming the area.

Choosing the right equipment

To choose the right equipment it is important to know the length and width of the ground floor or basement of the building.

If the length is less than twice the width, then we choose the equipment by looking at the m2 of the characteristics table.

For example, for a lower level with a length of 12m and a width of 8m, reference would be made to 12x8 = 96m2 of surface, since 12 is less than twice 8

Looking at the table of technical characteristics of the equipment, we deduce that the appropriate equipment is the HH-221a that covers up to 100m2.

Right equipment for an elongated ground floor

If it were the case of an elongated lower level of 16m long and 5m wide, in that case 16 is greater than twice the width, and the equipment should be chosen by the radius of action, taking half the longest length that would be with radius 8m corresponding to the HS-221b.

In most cases it is best to place the equipment on a support wall, even if it is not in the center of the level, because being thick, the transmission through the walls and floors is optimal, effectively covering all the walls of that level, although they are in different rooms.

Our system does not transmit just by air, but by the interior of walls and floors, reaching more easily to places with humidity and consequently drying in the most efficient way possible.

It is of vital importance that it is fixed to the support wall without intermediate layers of ceramics, marble, partitions, polystyrene, plastic, wood, etc. since this way the transmission to the interior of the wall is unimpeded.

Taking into account these installation precautions, it is possible to dry a whole ground floor in less than 4 months if the walls are brick or concrete blocks. However, if the walls are very old and thick (70cm) and made with stones, sand, earth, and some cement, the drying process is usually less than 9 months, as has been proven in old houses.
