Unibar F by Winkler was chosen for the protection and waterproofing of the floors and walls. <\/p>\n<p><!-- divi:heading {\"level\":3} --><\/p>\n<h3 class=\"wp-block-heading\"><strong>The challenge of modern rainfall and Parabiago\u2019s innovative solution<\/strong><\/h3>\n<p><!-- \/divi:heading --><\/p>\n<p>Recent <strong>meteorological events <\/strong>have drastically altered their characteristics and predictability. Unfortunately, flooding is now a frequent occurrence, even in city centres, particularly near waterways that overflow due to severe weather. <\/p>\n<p><a href=\"https:\/\/www.comune.parabiago.mi.it\/\" target=\"_blank\" rel=\"noopener\">municipality of Parabiago<\/a><strong> <\/strong>To combat this escalating problem, the municipality of Parabiago has implemented a significant intervention to minimise its effects: the construction of a 10,000 cubic metre underground accumulation tank. This tank, located beneath a car park, serves to temporarily store rainwater that the sewage network cannot handle during heavy downpours, thereby preventing network overload. Once the adverse weather subsides, a pumping system activates, releasing the accumulated water into the sewage network downstream for proper purification.\n<\/p>\n<p><!-- divi:heading {\"level\":3} --><\/p>\n<h3 class=\"wp-block-heading\"><strong>Unibar F: the ideal waterproofing for a cyclically used structure<\/strong><\/h3>\n<p><!-- \/divi:heading --><\/p>\n<p>The tank has a footprint of 1500 m\u00b2 and is 8 meters deep, and is completely underground. This tank, therefore, will fill and empty cyclically, and it was essential to protect the concrete structure from the effects of water and humidity, to always guarantee its integrity.<br \/>Having to work with a thin layer of material, we chose to propose the UNIBAR F product by Winkler, the two-component, water-breathable epoxy finish, suitable for protecting concrete floors and plinths, even those subject to moisture and without a vapour barrier. Unibar F, in fact, despite being a breathable product, creates a surface with good resistance to diluted acid, alkaline and saline solutions.  <\/p>\n<p>For this implementation, two coats of gray Unibar F were applied with a roller for a total consumption of 400\/500 g\/m\u00b2, covering not only the floors but also the walls and pillars. With this application, perfect waterproofing of the tank was achieved, allowing for a high speed of installation with consequent savings in labor costs. Like all the products in the Winkler range, Unibar F is also solvent-free and ensures very low emissions, in perfect line with the Winkler-Safe philosophy which involves the creation of systems and products with excellent technical performance that also take human health into account and the environment.   <\/p>\n<p><strong>Useful tips for Unibar F application<\/strong><\/p>\n<p>For optimal results when applying Unibar F, ensure the surfaces are clean and free from loose particles, anti-adherent substances, and oils. Perform thorough sandblasting, sanding, shot peening, or milling. The surface must have a tear resistance of at least 1.5 N\/mm\u00b2. To reduce future soiling and enhance the product\u2019s durability, we recommend applying the transparent topcoats WINMAT (matt) or WINGLOSS (gloss).   <\/p>\n<p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=&#8221;1_3,1_3,1_3&#8243; _builder_version=&#8221;4.27.5&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221; theme_builder_area=&#8221;post_content&#8221;][et_pb_column type=&#8221;1_3&#8243; _builder_version=&#8221;4.27.5&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221; theme_builder_area=&#8221;post_content&#8221;][et_pb_image src=&#8221;https:\/\/winklerchimica.com\/wp-content\/uploads\/2026\/01\/IMPERMEABILIZZARE-E-PROTEGGERE-IL-CALCESTRUZZO-A-PARABIAGO-galleria.webp&#8221; title_text=&#8221;WATERPROOF-AND-PROTECT-CONCRETE-IN-PARABIAGO-gallery&#8221; _builder_version=&#8221;4.27.5&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221; theme_builder_area=&#8221;post_content&#8221;][\/et_pb_image][\/et_pb_column][et_pb_column type=&#8221;1_3&#8243; _builder_version=&#8221;4.27.5&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221; theme_builder_area=&#8221;post_content&#8221;][et_pb_image src=&#8221;https:\/\/winklerchimica.com\/wp-content\/uploads\/2026\/01\/IMPERMEABILIZZARE-E-PROTEGGERE-IL-CALCESTRUZZO-PARABIAGO-galleria.webp&#8221; title_text=&#8221;WATERPROOF-AND-PROTECT-CONCRETE-IN-PARABIAGO-gallery&#8221; _builder_version=&#8221;4.27.5&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221; theme_builder_area=&#8221;post_content&#8221;][\/et_pb_image][\/et_pb_column][et_pb_column type=&#8221;1_3&#8243; _builder_version=&#8221;4.27.5&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221; theme_builder_area=&#8221;post_content&#8221;][et_pb_image src=&#8221;https:\/\/winklerchimica.com\/wp-content\/uploads\/2026\/01\/IMPERMEABILIZZARE-E-PROTEGGERE-IL-CALCESTRUZZO-galleria.webp&#8221; title_text=&#8221;WATERPROOF-PROTECT-THE-CONCRETE-tunnel&#8221; _builder_version=&#8221;4.27.5&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221; theme_builder_area=&#8221;post_content&#8221;][\/et_pb_image][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=&#8221;4.27.5&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221; theme_builder_area=&#8221;post_content&#8221;][et_pb_column type=&#8221;4_4&#8243; _builder_version=&#8221;4.27.5&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221; theme_builder_area=&#8221;post_content&#8221;][et_pb_image src=&#8221;https:\/\/winklerchimica.com\/wp-content\/uploads\/2026\/01\/IMPERMEABILIZZARE-PROTEGGERE-IL-CALCESTRUZZO-galleria.webp&#8221; title_text=&#8221;WATERPROOF-PROTECT-THE-CONCRETE-tunnel&#8221; _builder_version=&#8221;4.27.5&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221; theme_builder_area=&#8221;post_content&#8221;][\/et_pb_image][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=&#8221;4.27.5&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221; theme_builder_area=&#8221;post_content&#8221;][et_pb_column type=&#8221;4_4&#8243; _builder_version=&#8221;4.27.5&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221; theme_builder_area=&#8221;post_content&#8221;][et_pb_text _builder_version=&#8221;4.27.5&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221; theme_builder_area=&#8221;post_content&#8221;]<\/p>\n<h2 class=\"wp-block-heading has-luminous-vivid-orange-color has-text-color has-link-color\"><span class=\"ez-toc-section\" id=\"FAQ\"><\/span>FAQ<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>&nbsp;<\/p>\n<h4 class=\"wp-block-heading has-medium-font-size\">What product is used to waterproof large concrete structures?<\/h4>\n<p>For large tanks, two-component epoxy finishes like Unibar F are used.
