How to get rid of the increased moisture? This is one of the most frequently asked questions when it comes to thermal insulation and living comfort. We often consider that every phenomenon related to humidity is the same as another but this is not the case, in fact there are different types and in this guide we will explain how to prevent and eliminate it permanently.
One of the most dangerous phenomena that can occur in your home is increased humidity. This kind of phenomenon, in fact, destructively affects the walls and, if not acted upon as quickly as possible, risks causing them to rot first from the inside and then from the outside. Given the danger of this phenomenon, let’s get acquainted better with increased humidity and, first of all, how to treat this problem. Let’s Begin!

High humidity: what is it and how is it formed?
With the name of increased humidity, we mean that the phenomenon of moisture affecting the walls is not waterproof due to problems caused by rainwater and aquifer rise, but not only: this type of moisture can also be caused by accidental problems such as pipe rupture.
High humidity is mainly caused by the passage of water from the floor to floors and walls, which is why the most affected areas are usually basements, basements and the ground floor. This type of moisture results from the presence of water that rises on the walls and carries with it crystals of mineral salts that are then responsible for the aesthetic damage to the wall.
Old houses are the most susceptible to this type of moisture as in the past we did not have the foresight to create waterproof walls capable of insulating the house from the cold, but we thought only of building the house. On the other hand, new homes are less susceptible to this phenomenon, especially if proper thermal insulation is done in different rooms of the building.
How do you recognize the presence of increased humidity?
Here are some symptoms that should make us think about the presence of moisture:
- Mold: forms in the lower area of the walls and the color is usually yellow-green, both shape and color differ from mold that occurs instead on the ceiling (usually black and speckled)
- Plaster crumbling and detachment: due to the water salts crystallizing, the grout begins to swell and eventually peels off
- Floor, Furniture and Wall Problems: When the phenomenon continues to appear, the floor and furniture tend to be damp and therefore easily deteriorate.
It is good to keep in mind that this type of moisture, unfortunately, does not always show these problems immediately, and this is because the water that rises first runs inside the walls and only after months or even years do you start to see mold spots on the wall.
2 things not to do if you notice problems with high humidity!
- change plasters with more porous materials;
- mask the problem with products that only temporarily eliminate moisture, without acting properly inside the walls, such as sprays or soothing treatments;
Effects of high humidity
Before going to see in detail what are the best solutions for high humidity, it is necessary to focus on the damage to the walls and what happens if it is not stopped properly in time.
One of the most famous damage caused by this type of wet infiltration is the rotting of bricks, mortar and plaster of which the wall is made. When bricks and plaster disintegrate, it causes not only an aesthetic problem, but also the house becomes colder in winter and warmer in summer, due to which the thermal insulation of the house is compromised.
When increased moisture lurks inside the walls either in winter or summer (perhaps due to the heat that builds up on the walls) it begins to evaporate, causing condensation to form inside the room. In this way, not only does the environment and the air you breathe become damp, but over time condensation deposits on the walls lead to the formation of mold and the consequent decrease in the health of the air.
Structural problems caused by high humidity
- Wet spots and circles
- peeling paint
- Swelling and detachment of the plaster
- the presence of mold
- Salt blooms in water
Damage from high humidity results not only from structural and aesthetic problems but also from economic problems. Indeed, when there are problems with moisture on the walls, heat dissipation increases with increased consumption of gas or electricity for heating rooms, as well as damage to furniture in the rooms.
In addition to economic and structural damage, there is also the so-called static damage , the latter implying the weakening of the walls and their subsequent deterioration. These problems are due to all the mineral salts in the soil that dissolve in water and then rise inside the walls subject to high humidity.
The ascent process in the initial stage usually does not reach the ceilings, but reaches the wall to a certain height (usually halfway). The area in which moisture is expressed most often is called the water line or the area of evaporation.
Get rid of the increased moisture by thermal insulation: the solution and prevention
To prevent high humidity, the first thing to do is to intervene underground with a screed and selected sheaths, as well as pumps that properly drain excess water from under the house. However, this intervention alone is not enough, to properly prevent the humidity from rising, it is necessary to work with thermal insulation .
Water lift pump for liquid disposal under the house
A water lift pump is the solution or preventative measure to remove excess water that rises from an aquifer. A lift pump is a device that allows you to get rid of excess water under the house and make it flow into a special well or tank.
Usually in basements such as garages and basements this work should be done before going to build the property. If it does not, then it is necessary to try to overcome this problem through the use of electric pumps that are able to properly draw out the excess water that is formed in the primary area of the house and which tends to flow back under it properly. floors, which then also reach the walls, resulting in high humidity.
The installation of water lift pumps or submersible pumps is very useful when there are floods, heavy rains and weather phenomena that lead to an increase in the underlying aquifer. Installing the pump is not an easy task, so it is necessary to rely on a professional who can perform the intervention in the optimal way. Indeed, only a professional can assess the pump pressure, connection height, type of water and the proper system of water flow under the house.
Installation of panels against increased humidity: the correct procedure
When the rising moisture has already destroyed the walls, it is necessary to do various works to make the walls clean, dry and also free of any mold. Before doing the thermal insulation of the walls, if you encounter problems with high humidity, it is necessary to restore the wall by eliminating the problems inside that have deteriorated the plaster and paint.
Therefore, before taking action to carry out proper thermal insulation, it is necessary to remove all parts of the plaster that have been damaged. Once you have removed the damaged plaster and paint, you should proceed to properly reconfigure the wall, for this you will need the adhesive first.
This product makes plaster stick better. Choose an alkaline and heat-resistant plaster, this way the wall will maintain its health and will not again cause problems with mold.
Once the grout has been restyled, you can also choose to apply an alkaline anti-mold paint, which allows you to better remove both condensation and increased moisture.
Having properly restored the condition of the walls, you can then proceed to the thermal insulation of the house and thereby resist the increased moisture in a final and permanent way.
To do the correct insulation, you should choose a natural product that is able to remove moisture as much as possible. Among the best cork boards, this is actually an insulator that allows you to retain moisture without releasing it later inside the wall. Since we are going to recreate a counter wall to get rid of the increased moisture, the advice is to buy duplex boards like the ones available in our store that include gypsum board combined with cork board.
To buy the correct number of cork and gypsum duplex boards, remember to take measurements of the walls that need to be reconstructed, once the measurements are made, you can proceed with the purchase and of course the thermal insulation work.
But be careful, do not forget that in addition to double cork and plasterboard sheets, it is also necessary to take the necessary for fixing them to the wall. For this you will need aluminum guides, in addition to straight guides and you will also need corner guides to connect the walls. Finally, you will also need screws, mounting stoppers, paper tape, anti-mold alkaline paint, thin and always alkaline white grout. Don’t worry: if you need advice or pointers, our team of experts is available to advise you on and assemble the product best suited to your needs, absolutely free of charge.
Permanently High Humidity In 6 Steps, Here’s How!
- Start building the structure with aluminum guides, clamped in height and all around the walls, then horizontal to create a complete and resistant structure, remembering to assemble everything leaving an inch from the wall. Once the guides are properly fixed thanks to the use of screws for the aluminum guides, you can proceed to insert the boards
- The panels should be placed inside the aluminum guides, and should be installed from the bottom up, for good stability you will also need to use nails to secure the inner casing and insulating material. It is normal for the cork tape to face inward, while the plasterboard area faces the outside
- All plasterboard fixed, check that there are no spaces and if instead you find “holes” between one board and another you can use gauze and lime to be able to make the plasterboard wall more uniform
- Once you have the monolithic walls, you should start making the plaster, before applying it, however, it is recommended to put some mesh rack to make the structure more linear
- After installing the gypsum holder grids, you can start kneading and then apply a layer of thin breathable gypsum, alkanine and white to the plasterboard
- Finally, after the plaster has dried properly, it will be possible to complete the task with a porous and anti-mold coating
All this work, once done in areas or rather in rooms affected by high humidity, allows not only to have a home less humid and free from the described problems, but also warmer in winter and cooler in summer.
As we said earlier, in fact, high humidity is a problem that leads to deterioration of the walls and damage to the insulation of rooms and the entire house. When you suffer this damage, the house becomes wetter and cooler and therefore more is spent heating or cooling the house.
Thanks to the thermal insulation in rooms affected by humidity, you will be able to have an environment with a constant temperature, so you will not have to spend excessively to warm them or to cool the environment all year round.
