The physical aspect of an environment greatly influences the comfort and well-being of those who frequent the space.
Therefore, in addition to investing in the exterior and interior decoration of the house, it is very important that you, as the property owner, be aware of the emergence of some factors that may compromise the beauty and comfort of the residents, such as rising humidity.
You've probably walked into some room and noticed the presence of stained and peeling walls at the bottom of the wall, right?
This problem, in addition to affecting the appearance of the coating, also affects the health of those who frequent the environment, because of the appearance of mold and mildew on the walls.
Therefore, taking appropriate care to prevent the onset of this problem is essential.
Knowing this, we prepared this article with the purpose of explaining to you what rising humidity is and what to do to prevent its onset. Follow the reading!
Rising damp refers to infiltrations that occur because of the capillarity effect of the water present in the soil rising against the force of gravity in the coating.
This is a waterlogging that occurs from the bottom up, since the soil moisture is absorbed by the wall, and in some cases the stain on the surface can reach a height of one meter in relation to the floor. We have witnessed some cases even above one and a half meters above the ground.
The first sign of this problem is the appearance of small bubbles under the paint near the baseboard, which, when neglected, can become larger and contribute to the appearance of mold and mildew. In general, the main responsible for causing moisture in the walls are the materials that were used in the construction.
This is because regardless of the quality of waterproofing, over time, the iron rebars that were used to make the underpinning and the pillars, for example, serve as a guide to direct moisture to the walls. Not to mention that the pores of the brickwork itself serve as “sponges” that absorb soil water.
Because of this, buildings that use materials with a high percentage of porosity tend to absorb more moisture from the soil. Then, consequently, the water suction pressure will be higher and so will the deterioration of the walls.

How to avoid rising damp?
As we have already mentioned, humidity not only impairs the physical appearance of the wall surface, but also damages the building structure and affects the health of those who frequent the environment. To give you an idea, mold is responsible for causing allergic diseases, rhinitis, dry cough, headaches, worsening the health of those with asthma and transmitting bacteria that cause infections.
In more serious cases, it is possible to trigger pneumonia and eye problems in people who live in environments with an incidence of mold. In this way, the spores cause skin and eye irritations, itchy skin and eye allergies. The situation is even worse when the exposed people are the elderly, pregnant women, children, or those who have had an illness that left them with immunodeficiency.
Although moisture problems are common and sooner or later they appear on the walls, it is very important for homeowners to be concerned about seeking alternatives that delay these problems as much as possible. Remember that, when care is taken from the beginning of construction, it is possible to ensure that no infiltration of the walls occurs under any circumstances.
Therefore, if you are going to build your property, be concerned about waterproof the foundation structures that will have direct contact with the ground, such as the baldrame beam and the level brickwork.
In large buildings, it is ideal to use waterproofing agents integral or deep in the concrete of any structure that has contact with the ground, such as blocks of concrete, beams Baldrame and the top basement floor.
In smaller buildings, it is necessary to waterproof materials such as crowning blocks and flat beams. To further prevent soil moisture from passing onto the walls, you can lay a layer of crushed stone on the bottom and sides of the structural elements.
If the moisture from the groundwater reaches the walls, it is ideal to do a deep drainage with the aid of draining trenches. In addition, we recommend that you use gutters and ruffles to avoid creating puddles in the immediate vicinity of your property.
These tips from waterproofing of the materials that maintain contact with the ground are suitable for those who are in the construction phase. Now, if the property is ready and the rising humidity has already indicated its appearance, the ideal is to remove all the wall covering to undergo a new treatment with polymer mortar.
Other tips you can adopt are:
for those of you who are still going to build, prioritize a construction that favors ventilation, adequate insulation, lighting and avoids practices that result in the condensation of water in the soil;
if the property is being built in a humid region, be careful to choose quality materials with less porosity and do the waterproofing of everything that may contribute to humidity;
use a dehumidifier in cloudy periods or when the air conditioner is constantly on;
make use of anti-mildew paints;
carry out preventive maintenance constantly;
keep the environment always ventilated.
How does waterproofing work?
Waterproofing is nothing more than the application of a product waterproof in areas and materials that you want to protect against moisture. But for Get the right choice of the product it is important to take into account the type of the structure and the force of the water pressure, which can be Positive or negative.
In this case, positive pressure occurs when water force is applied directly onto the waterproofing system. Whereas negative pressure is when water pressure is applied in the opposite direction to the waterproofing system.
These were our tips for you to avoid the onset of rising humidity. Although we know that humidity is a constant problem in certain situations, we stress even more the importance of valuing the quality of the materials and carrying out the correct waterproofing and preventive maintenance, in order to keep this problem as far away from your property as possible.
