Technical dehumidification
After a flood, it is essential to carry out an accurate assessment of the humidity level present in walls, attics and floors.
The first operational step is to remove all standing water. This operation can be done with pumps or water aspirators, depending on the quantity of water present. AND important to act promptly to prevent water from penetrating further into the structures.
Once the water has been removed, with the support of a technician, core drilling can be carried out in the walls to investigate the presence of water and identify which areas require intervention.
To dehumidify, the room must be well ventilated to accelerate the evaporation of residual humidity. The actions to be carried out depend on the location of the room in question which may be underground or above ground. The controlled opening of doors and windows, together with the use of fans, dehumidifiers and heating systems, helps reduce the level of humidity in the air and on surfaces.
Dehumidifiers are fundamental tools at this stage. There are different types of dehumidifiers: condensation and absorption, which can be chosen based on the severity of the flooding and the size of the room to be treated. These devices absorb moisture from the air, speeding up the drying process.
It is essential that any type of action to be carried out within the premises takes place with the support from qualified technicians.
During the dehumidification process, it is necessary to monitor humidity levels and the condition of surfaces. The process can take several days or weeks depending on the extent of damage to the premises.
Extraction of water and sludge from technological systems
In the video, the importance of extracting water and sludge from technological systems as a crucial post-flooding phase is underlined. The electrical systems they are particularly vulnerable to water damage.
The first step is to disconnect the electrical system and then proceed with the physical elimination of stagnant water, for which tools such as rigid cannulae with syringes or silicone tubes are used. Once the water and mud have been eliminated, it is important to carry out a thorough check of the systems to identify any damage to the electrical or hydraulic components with the support of qualified operators.
Verification with thermography
There thermography it is a non-invasive technique, used to check the presence of residual humidity inside building structures after flooding. Through the use of thermal imaging cameras, it is possible to identify hidden areas where water may have infiltrated and stagnated, causing potential long-term damage. Thermographic images highlight surface temperature differences, allowing you to visualize the distribution of humidity within walls, attics and floors.
This method is particularly useful for identifying accumulations of water not visible to the naked eye, thus avoiding invasive and destructive interventions.
Dry cleaning of surfaces
There dry cleaning of surfaces represents one of the essential phases in post-flooding sanitation, especially for those materials that cannot be treated with water or other liquids.
The use of brushes is recommended to remove dust, mud and solid debris from surfaces without introducing additional water into the structures. Dry cleaning is particularly useful for treating reinforced concrete structures that may be damaged by water reaching the reinforcement.
