The result is operating conditions subjected to\u00a0positive hydrostatic thrust (thrust)<\/strong>\u00a0and\u00a0negative hydrostatic thrust (counter thrust)<\/strong>\u00a0.<\/p>\n

In the following images:
\nThe condition of\u00a0\u00a0positive hydrostatic thrust\u00a0<\/strong>\u00a0(upthrust),<\/strong>\u00a0occurs when the liquid exerts pressure directly on the coating, which is then compressed on the support: images A and B;
\nThe condition of\u00a0\u00a0negative hydrostatic thrust (counter-thrust),<\/strong>\u00a0\u00a0occurs when the liquid exerts pressure at the coating adhesion interface exerting pressure aimed at detaching the coating from the support: images C and D.<\/p>\n

To fully achieve the performance of osmotic cementitious waterproofing, especially in counterthrust, the porosity of the support (which in concrete is equal to approximately 200,000,000 \/ m\u00b2), is a resource that must be “opened” to osmotic diffusion![\/vc_column_text][\/vc_column][\/vc_row][vc_row row_type=”row_full_center_content” margin_top=”0″ padding_top=”0″][vc_column width=”1\/3″][vc_single_image image=”91″ img_size=”full” alignment=”center” css_animation=”bottom-to-top”][\/vc_column][vc_column width=”1\/3″][vc_single_image image=”92″ img_size=”full” alignment=”center” css_animation=”bottom-to-top”][\/vc_column][vc_column width=”1\/3″][vc_single_image image=”93″ img_size=”full” alignment=”center” css_animation=”bottom-to-top”][\/vc_column][\/vc_row][vc_row row_type=”row_full_center_content” class=”gruppoBtns”][vc_column width=”1\/4″][vc_button title=”History” color=”custom” button_custom_color=”#00a5cc” position=”center” link=”url:https%3A%2F%2Fwww.osmocem.com%2Ftechnology%2Fhistory%2F|title:History||”][\/vc_column][vc_column width=”1\/4″][vc_button title=”Adhesion mechanisms” color=”custom” button_custom_color=”#00a5cc” position=”center” link=”url:https%3A%2F%2Fwww.osmocem.com%2Ftechnology%2Fadhesion-mechanisms%2F|title:Adhesion%20mechanisms||”][\/vc_column][vc_column width=”1\/4″][vc_button title=”Practical advice” color=”custom” button_custom_color=”#00a5cc” position=”center” link=”url:https%3A%2F%2Fwww.osmocem.com%2Ftechnology%2Fpractical-advice%2F|title:Practical%20advice||”][\/vc_column][vc_column width=”1\/4″][vc_button title=”Complete line” color=”custom” button_custom_color=”#00a5cc” position=”center” link=”url:https%3A%2F%2Fwww.osmocem.com%2Ftechnology%2Fcomplete-line%2F|title:Complete%20line||”][\/vc_column][\/vc_row]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
