WHAT IS CAPILLARY RISING DAMP?

WHAT CAUSES IT IN THE WALLS OF BUILDINGS?

The rotation of the Earth and its electrical, magnetic, geological and chemical characteristics create natural electromagnetic fields in certain geographical areas where buildings are constructed.

These electromagnetic fields induce electric charges in walls. The charges are very weak, but combined with the electric charges resulting from the circulation of water in the capillary system (zeta potential) and over a period of time they are the cause of rising damp in walls. The result is more or less evident depending on the type of material, its porosity, mineral salt content, etc.

To understand what happens in the capillary system of materials, which comprises bipolar molecules of water, and capillaries, you need to know that the system behaves like a cylindrical electrical condenser. Different concentrations of charges are observed depending on the level of the layers of water molecules and capillaries.

In the case of capillary rising damp, the electromotive force (emf) is oriented along the red arrow that is causing the water molecules in the capillaries up the wall.(see diagram)

The action of the Mur-Tronic process modifies the electrical charges in the air by neutralizing the force along the arrow in green, which prevents water molecules from migrating up the wall. (see diagram) It consists of sending very weak electromagnetic signals to the capillary system, thereby constantly modifying the polarity of the layers separating the charges in the capillaries. The surface tension of water and the angle of the meniscus in the capillaries is changed.

This principle makes it possible to neutralise the links between the H2O and salt ions and to lower the surface tension of the water which is high because of hydrogen bridges. This result is achieved using very little energy, contrary to the principle of electro-osmosis, which requires a greater input of energy.

The movement of water towards the top of the wall is halted i.e. the osmotic pressure is thus destroyed and the walls dry out, even in very damp environments.

It is easy to see that the process does not merely mask the effects of the rising damp, as is often the case with the chemical and other methods used over the past decades, but deals with the cause, i.e. the electrical characteristics of the soil and the chemical components of the walls.
