Decor : The effects of torrential rains on buildings
The DANA, which has affected a large part of our geography in recent days, has caused extensive damage to homes, businesses or public roads, to name a few chaos. But the thing does not end here, since after the torrential rains, one of the most common problems that must be faced is the appearance of the dreaded structural dampness due to the large amount of water that the ground absorbs and passes through. the walls and foundations of buildings.
Due to this situation, from Murprotec they have highlighted the importance of the different humidities that can develop, as well as their most negative effects, both for the structure and for the health of people.
Different types of humidity
Due to the amount of water generated that saturates the land, the dreaded dampness can appear by capillarity -on ground floors- and by lateral seepage -in basements, garages, or parking lots-. Capillarity damp appears because the ground has to absorb a lot of moisture and the walls of buildings –which have a great capacity to absorb underground water– filter the water as if it were a sponge. And it is, in this phase, when the materials in contact with the underground water and with the humid earth let the humidity rise through their walls and capillaries, causing humidity that can reach one and a half meters in height.
Lateral seepage dampness arises when water present on the other side of a wall penetrates into the building through the wall laterally. Therefore, all rooms in direct contact with the earth on which the building is built are very sensitive to suffering from this type of humidity.
It must also be taken into account that a strong thermal contrast between exterior and interior, together with poor or no ventilation, can produce condensation. This phenomenon is generated when an excessive level of water vapor is produced in the environment.
The warning signs
Structural dampness manifests itself in multiple ways: from cracks, to saltpeter on the walls, chips, fungus or mold in upper corners in basements or on window frames and, of course, that characteristic musty smell that surrounds the affected room. .
Faced with these warning signs, it is essential to put yourself in the hands of professionals for a timely diagnosis and, above all, a correct solution that ends the problem at its roots.
The serious consequences of humidity
Humidity in a building can compromise both its stability and the health of those who suffer from it. The process of corrosion and oxidation that water brings with it can cause structural collapse by weakening walls and foundations. But, above all, humidity increases health problems for those affected, affecting even more risk groups such as the elderly, children, immunosuppressed people or pregnant women. The increase in flu processes, respiratory problems such as asthma, bronchitis and pneumonia, allergies and dermatitis, rheumatic conditions and even eye diseases such as chronic rhinitis, are common symptoms when living with humidity.
