of which the masonry is composed and the presence and diffusion of any discontinuities on it.<\/p>\n

In this case, the infiltrations generally come from atmospheric precipitations: rain, snow<\/strong>\u00a0that penetrate the walls through cracks and micro-cracks in the plaster, damaged repointing brickworks, metal and wooden carpentry, door and window frames embedded in the masonry, etc.<\/p>\n

The walls frequently exposed to rain can easily moisten and saturate, especially in the presence of the pressure exerted by the wind which can facilitate the penetration of moisture into the wall fabrics.<\/p>\n

In general,\u00a0the effects of pouring rain are closely related to the morphology of the buildings<\/strong>\u00a0and can be accentuated in the presence of any local defects in the external envelope.\u00a0In fact, the plaster does not only have the function of ensuring a uniform coverage of the building, but also the fundamental one, of guaranteeing protection from the effects of pouring rain and meteoric agents in general.\u00a0In the case of porous materials, the protective function of the plaster is fundamental<\/strong>.<\/p>\n

For particularly exposed walls,\u00a0water-repellent plasters and\/or aids capable of inhibiting the transport of water are recommended.\u00a0In any case, the plasters must be able to guarantee a sufficient exchange of steam between the internal part of the wall and the external environment.<\/strong><\/p>\n

The thermal properties (insulation), the influences on condensation processes, damage caused by freeze-thaw cycles, as well as the overall durability of the building itself also depend on the penetration of water into the masonry<\/strong>.\u00a0The phenomena of degradation of bodies and masonry envelopes are in fact closely connected with the possibility of aggressive substances to penetrate the masonry.[\/vc_column_text][\/vc_column][vc_column width=”1\/2″ css=”.vc_custom_1584653763281{padding-left: 0px !important;}”][vc_single_image image=”1211″ img_size=”large” onclick=”zoom” css=”.vc_custom_1584873689278{margin-top: 0px !important;margin-right: 0px !important;margin-bottom: 0px !important;margin-left: 0px !important;padding-top: 0px !important;padding-right: 0px !important;padding-bottom: 0px !important;padding-left: 0px !important;}”][\/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:1616404172436-78071705-dc3b-8″ include=”542,589,592,586″ el_class=”allignBottom”][\/vc_column][\/vc_row][vc_row row_type=”row_full_center_content”][vc_column][vc_custom_heading text=”Products and technologies to use” font_container=”tag:h2|font_size:24px|text_align:left|color:%233c6422|line_height:30px” use_theme_fonts=”yes”][vc_column_text]<\/p>\n

The problems deriving from the permeation humidity can be solved by sealing the existing cracks<\/strong>, with putties, filler products and polymeric sealants and\u00a0by applying\u00a0water-repellent<\/strong>\u00a0(transparent or pigmented)\u00a0treatments and\/or paints<\/strong>\u00a0(or renders).<\/p>\n
