The humidity in the building is manifested above all if the correct ventilation times of the rooms<\/strong>, foreseen by the building and hygiene regulations in force during the\u00a0construction works, are not respected<\/strong>.\u00a0During these interventions, building materials retain liquids for a long time, especially if the works proceed without respecting the drying times of the previous processing.<\/p>\n

If your home has been built for less than 12 months, residual moisture is very likely.<\/strong><\/p>\n

The main visible phenomena, to check for their presence, are\u00a0mold on the walls and high humidity in the indoor air<\/strong>, often accompanied by an annoying smell.<\/p>\n

Based on documented statistics based on the analysis of hundreds of new homes, made by appropriate and sophisticated instrumental investigations, 80% of them were found to have residual building moisture.<\/p>\n

In renovated houses, this percentage was only 5% (therefore in the remaining 95% of cases the other different types of humidity coexisted up to now coexist).<\/p>\n

There is no immediate remedy for residual moisture from construction works.<\/strong><\/p>\n

The best intervention is to wait for the natural dehumidification of the walls and other artifacts.<\/strong><\/p>\n

In normal conditions, in fact, the residual humidity\u00a0disappears spontaneously by evaporation on the basis of the “drying times”<\/strong>\u00a0which can be calculated, albeit with great approximation, on the basis of the elements recalled in the image.[\/vc_column_text][\/vc_column][vc_column width=”1\/2″][vc_single_image image=”1250″ img_size=”large” alignment=”center” onclick=”zoom”][\/vc_column][\/vc_row][vc_row row_type=”row_full_center_content” margin_top=”30px” margin_bottom=”0″ padding_top=”0″ padding_bottom=”0″][vc_column el_class=”relative”][vc_media_grid element_width=”3″ gap=”15″ item=”289″ grid_id=”vc_gid:1616426419718-6b4dc487-5c52-7″ include=”918,909,912,915″ el_class=”allignBottom”][\/vc_column][\/vc_row][vc_row row_type=”row_full_center_content”][vc_column][vc_column_text]Drainage is a function of a {tooltip}coefficient (p<\/strong>){end-texte}\"\"{end-tooltip}, characteristic for each type of masonry, and of the thickness (s<\/strong>) of the masonry itself (expressed in centimeters).<\/p>\n
