The <strong>waterproofing<\/strong> action of <strong>bituminous membranes<\/strong> on <strong>flat roofs<\/strong> can be compromised by several factors, some of which are described hereafter. These surfaces are subject to <strong>thermal excursions<\/strong> (<strong>freeze-thaw cycles<\/strong>), to the action of bad weather (rain, wind), of UV and to mechanical stresses. All these elements contribute to reduce the effect of the <strong>waterproofing<\/strong> material\u2019s seal, compromising the nature of the coating. This, in turn, can lead to the creation of <strong>cracks<\/strong> and <strong>fractures<\/strong>, thus facilitating the damaging action of the water.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Critical areas of bituminous membranes<\/strong><\/h3>\n\n\n\n<p>When <strong>waterproofing<\/strong> using torched-down <strong>bituminous membranes<\/strong>, butt and side <strong>welds<\/strong> are generally considered the most critical and vulnerable areas. It is also necessary to consider the action of <strong>stagnant water<\/strong>, which contains acidic elements that can corrode the bituminous surface over time. The result is the <strong>detachment<\/strong> of some welding and the formation of <strong>cracks<\/strong> and holes. If the above happens, the <strong>waterproofing<\/strong> loses its uniformity and continuity, and therefore its effectiveness.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Best practices to help prevent damage<\/strong><\/h3>\n\n\n\n<p>Through attentive controls and <strong>periodic maintenances<\/strong> of <strong>flat roofs<\/strong> it is possible to <strong>repair damaged parts<\/strong> of the membranes. Therefore, we can prevent those situations that can damage <strong>waterproof coatings<\/strong>. In fact, we can implement different types of interventions that make the surface of <strong>flat roofs<\/strong> perfectly <strong>waterproofed<\/strong> and <strong>protected<\/strong>. This is possible thanks to the modern technology that offers <strong>innovative and high-performance solutions<\/strong> for these types of applications. These solutions not only protect the <strong>waterproofing<\/strong> function of <strong>bituminous membranes<\/strong>, but also <strong>restore damaged surfaces<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Actions to implement when repairing damaged bituminous membranes<\/strong><\/h3>\n\n\n\n<p>There are many possible cases of intervention for the <strong>repair of damaged bituminous membranes<\/strong>. For example, if it is necessary to <strong>regularize<\/strong> and <strong>renovate the slopes<\/strong> of bituminous substrates, whether they are composed of smooth or <strong>slated bituminous membranes<\/strong>, it is possible to use a <strong>ready-to-use one-component levelling paste<\/strong>. This <strong>levelling paste<\/strong> is <strong>bitumen<\/strong> and <strong>water based<\/strong>, it is easily workable and can also be used for the realization of connecting covings on the wall to floor corners of the roof. The use of <strong>adhesive sealants<\/strong> based on bitumen and high-quality polymers is recommended for the <strong>sealing of overlapping joints<\/strong> in the practice of <strong>cold laying<\/strong> of <strong>polymer- bitumen membranes<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Modern technologies offer innovative products<\/strong><\/h3>\n\n\n\n<p>The new products available in the market allow to effectively <strong>renovate old floors without removing the existing waterproofing<\/strong>. This is a great <strong>advantage in terms of time <\/strong>\u2013 the removal of the old membranes involves additional work which influences the costs \u2013 and in terms of the production of waste materials which must then be disposed of in the appropriate landfills.<\/p>\n\n\n\n<p>In order to <strong>cover the old membranes<\/strong> and <strong>renew the surface of roofs<\/strong>, nowadays we can use <a href=\"https:\/\/www.winklerchimica.com\/en\/portfolio\/one\/\"><strong>bituminous membranes <\/strong>with<strong> highly elastic aqueous emulsions<\/strong> like <strong>Winkler One<\/strong><\/a>. They <strong>resist aging<\/strong>, to <strong>cold-hot cycles<\/strong>, and remain unchanged both at low and high temperatures.<\/p>\n\n\n\n<p>When dealing with<strong> slated membranes<\/strong>, it is recommended to use special <strong>water-based transparent elastomeric liquid membranes<\/strong> (the most advanced techniques in the field of waterproofing do not include solvents), which guarantee<strong> <\/strong>maximum protection for the slated bituminous surface.<\/p>\n\n\n\n<p>In fact, in the above-mentioned situation, it is fundamental not to alter the aesthetic appearance of the roof and to prevent and limit the detachment of slate flakes<\/p>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-default is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1020\" height=\"630\" data-id=\"119080\" src=\"https:\/\/winklerchimica.com\/wp-content\/uploads\/2026\/03\/Winkler-One_Dimensioni_personalizzate_1020x630.webp\" alt=\"\" class=\"wp-image-119080\" srcset=\"https:\/\/winklerchimica.com\/wp-content\/uploads\/2026\/03\/Winkler-One_Dimensioni_personalizzate_1020x630.webp 1020w, https:\/\/winklerchimica.com\/wp-content\/uploads\/2026\/03\/Winkler-One_Dimensioni_personalizzate_1020x630-980x605.webp 980w, https:\/\/winklerchimica.com\/wp-content\/uploads\/2026\/03\/Winkler-One_Dimensioni_personalizzate_1020x630-480x296.webp 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) 1020px, 100vw\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1020\" height=\"630\" data-id=\"119081\" src=\"https:\/\/winklerchimica.com\/wp-content\/uploads\/2026\/03\/Damaged-Bituminous-Membranes_Dimensioni_personalizzate_1020x630.webp\" alt=\"\" class=\"wp-image-119081\" srcset=\"https:\/\/winklerchimica.com\/wp-content\/uploads\/2026\/03\/Damaged-Bituminous-Membranes_Dimensioni_personalizzate_1020x630.webp 1020w, https:\/\/winklerchimica.com\/wp-content\/uploads\/2026\/03\/Damaged-Bituminous-Membranes_Dimensioni_personalizzate_1020x630-980x605.webp 980w, https:\/\/winklerchimica.com\/wp-content\/uploads\/2026\/03\/Damaged-Bituminous-Membranes_Dimensioni_personalizzate_1020x630-480x296.webp 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) 1020px, 100vw\" \/><\/figure>\n<\/figure>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Conclusion: let\u2019s implement a \u201cProtection practice\u201d<\/strong><\/h3>\n\n\n\n<p>The innovative<strong> waterproofing products<\/strong>\u2019<strong> <\/strong>action is not limited to the <strong>protection from water and humidity.<\/strong> They offer performances that bring actual benefits to the economy of buildings.<\/p>\n\n\n\n<p>In <strong>repairing bituminous surfaces<\/strong> on <strong>flat roofs<\/strong>, some <strong>water-based<\/strong> products are <strong>restorative <\/strong>and <strong>protective<\/strong>, formulated with special fillers and additives that give a <a href=\"https:\/\/www.winklerchimica.com\/en\/portfolio\/wingum-plus-h2o\/\"><strong>high reflectivity<\/strong> to sun rays and high submissiveness in the infrared like <strong>Wingum Plus H20 REFLEX<\/strong><\/a>.
