Dehumidify your home: know the cause of the humidity to find the best solution

The internal environment of a home can be compromised by the presence of humidity and mold.
This problem does not only concern the aesthetic aspect of the interior, but goes much further, damaging the structure of the building itself and making the environment less healthy.
There are different types of humidity.

Rising damp and condensation: how to combat them

It can be about rising humidity which occurs when moisture from the ground penetrates the walls of the ground or basement floors, often due to a lack of adequate protective barriers at the base of the structure or the deterioration of these barriers over time.

Another typology is thecondensation humidity which occurs when the internal heat of the rooms meets cold surfaces, causing the formation of condensation and, consequently, the proliferation of mould. This situation can be aggravated by excessive thermal insulation and inadequate or absent ventilation.

Mold in the home: how it forms and how to resolve it

The presence of mold within a domestic environment constitutes a serious health riskas it promotes the growth of bacteria that release allergens harmful to the respiratory tract.
Mold manifests itself with dark, black or gray spots and with the deterioration of paint or plaster.

How to solve mold in your home

These signs can originate especially in humid and poorly ventilated areas such as kitchens and bathrooms where internal humidity tends to accumulate.

Rising damp, condensation damp and mould: what is the relationship between them

L’rising humidity acts as a contributing factor to increased humidity in the air. This happens when the humidity present in the ground penetrates the walls, rising through the capillary system of the walls to the ground floor. Once it reaches a certain height, it can no longer go back up and therefore manifests itself within the environments, increasing the humidity rate of the air.

Relationship between condensation, rising humidity and mould

Moisture trapped inside walls tends to cool them, reducing their temperature. Especially during the winter months, this phenomenon leads to the accumulation of humidity on the cold surface of the walls. The consequence is the surface condensation formationwhich creates ideal conditions for the development of mold.

Thus, rising humidity and condensation work together to create an environment conducive to the proliferation of mould, highlighting the importance of addressing and solving problems related to humidity in homes.

How to sanitize a house with rising damp in the walls and mould

First of all, it is important to understand that a wall affected by capillary rise has two significant effects.
First, it contributes to increase the humidity inside the house through the process of evaporation, secondly, it turns out to be colder compared to a dry wall.

Since high air humidity and low wall temperature are two of the main factors that favor the formation of mold, it is clear that the dehumidification process of walls has a positive impact on mold prevention.
A dry wall, in fact, does not release significant quantities of humidity into the internal environment and maintains a higher temperature than a damp wall.

Given these considerations, it is clear that tackling the problem of rising damp can at the same time combat or even prevent the appearance of mould.

Eliminate humidity in the house: what to do when it comes from the ground?

To effectively deal with rising humidity from the ground, one method used is mechanical cutting of the wallor the practice of directly cutting into the masonry to insert insulating panels. This approach, widely used in the past, was abandoned as it appeared invasive and he could compromising the structural stability of the building.

Another common technique is using chemical injections in walls to create a horizontal barrier using special resins. Although this method can be effective in the short term, it can present problems over time. Micro-cracks present in the masonry or caused by the action of atmospheric agents can compromise the effectiveness of the resin, making it vulnerable to erosion and reducing its ability to block humidity.

How to eliminate humidity in the house

Some alternative systems involve the application of plastic, wood or tile coverings to cover rising damp. However, such treatments do not really solve the problem, as the wall still remains damp. An aesthetic change occurs, but the internal conditions remain unchanged.

If you want real dehumidification of the masonry, you need to resort to advanced technologies based on the inversion of the electrical potential of the wall. These systems work by dehumidifying the masonry, inducing moisture molecules to flow back towards the ground, significantly and lastingly decreasing the level of humidity present in the wall.
