If you have found moisture in any interior wall of your house or it has happened to you before and you want to prevent it, in this article we are going to talk about how to repair and prevent its appearance.


Moisture on the interior walls of the home cannot be overlooked and requires that you correct it as soon as possible. To give you an idea, humidity can lead to structural problems, damage the furniture or materials that you have in the room and, in addition, it is also harmful to health.

Types of humidity and their solutions

There are three types of humidity and each requires a different solution:

Capillarity moisture

This type of humidity is caused by a poor insulation the foundation of the house and the start of the walls, so it is possible that a correct drainage has not been made. So, this time, we are talking about the fact that in most cases it is an error during the work.

Therefore, taking into account the aforementioned, this type of humidity comes from the subsoil and rises. It is considered to be difficult fix it since it implies that the foundations and walls must be drained and waterproofed. Does this mean that it is impossible? Absolutely. The option that is currently the most valued in the market is Electro-Físico HS-221, from, which manages to dry 4 times more.

Humitat Stop is the industry benchmark in capillary moisture and its Electro Physical System HS-221 It is considered the best on the market, which does not require work and can be installed by yourself. It is not just any product, but a system that represents a great advance compared to wireless electro-osmosis, since it is transmitted through the walls and not through the air, managing to dry much more than any other product.

The creators of this HS-221 system They are Juan Alberto Viñas, Doctor in Physical Sciences, and Mª del Mar Viñas Pinto, Senior Telecommunications Engineer. From their resumes we are going to highlight the passage of Dr. Juan Alberto Viñas as: Director of the Central Laboratory of Piher SA, Technical Director of Mobba, Technical Director of Epelsa and Technical Director of Ascell-Sensor, all of them companies that have achieved great strides in their areas. And, if we focus on Maria del Mar Viñas, his Master in Metrology from Brunel University (London), Master in Business Administration from ESADE and his work as Hardware Development Engineer at Comelta SA.

Moisture from leaks

As its name indicates, humidity by leaks They are produced by the filtration of water through fissures, joints or cracks, water leaks from walls and roofs, underground currents, internal breaks in water pipes, among others.

The solution It goes through locating and repairing the fault, either sealing the crack in the facade or locating the pipe that is losing water.

Humidity due to condensation

Condensation humidities are the most frequent since it is a contrast of temperatures that make the water go from being steam to condensing in the coldest parts of the house. As you will see, it does not occur in any house, if not it has to do with older houses or in which there is a bad enclosure. Therefore, the most common areas where mold stains appear are near windows, exterior walls and in the corners of them, etc.

The solution It is easier to do a good daily ventilation as a quick measure, then it is necessary to improve the insulation of these areas that face the outside since it will be possible to avoid those drastic changes in temperature that generate water vapor and condensation. Another option, if it happens especially in the area of ​​the windows, is to evaluate the option of putting some windows with thermal bridge break.
