In Catalonia and the Balearic Islands, where climatic conditions can vary significantly depending on the area, choosing between <strong>waterproofing with asphalt sheeting or with a liquid product<\/strong> can make a difference in the durability and efficiency of the work. In this article, we explain the differences, advantages and ideal applications of each system, to help you make the best decision according to your project.<\/p>\n\n<p><\/p>\n\n<h4 class=\"wp-block-heading\">What is asphalt sheet waterproofing?<\/h4>\n\n<p><\/p>\n\n<p><strong>Asphalt sheets<\/strong> are prefabricated materials formed by a base of asphalt modified with polymers and reinforced with stabilization reinforcements. These sheets are supplied in rolls and are generally applied by flame welding or special adhesives.<\/p>\n\n<p><\/p>\n\n<h5 class=\"wp-block-heading\">Advantages of asphalt sheeting:<\/h5>\n\n<p><\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>High mechanical resistance<\/strong> : ideal for walkable roofs or areas with moderate traffic.<\/li>\n\n\n\n<li><strong>Guaranteed durability<\/strong> : can last up to 20-25 years if installed correctly.<\/li>\n\n\n\n<li><strong>Resistant to structural expansions<\/strong> .<\/li>\n\n\n\n<li><strong>Economical on large flat surfaces<\/strong> .<\/li>\n<\/ul>\n\n<p><\/p>\n\n<h5 class=\"wp-block-heading\">Common applications:<\/h5>\n\n<p><\/p>\n\n<ul class=\"wp-block-list\">\n<li>Walkable and non-walkable flat roofs.<\/li>\n\n\n\n<li>Community terraces.<\/li>\n\n\n\n<li>Floors with anti-puncture membrane for extra protection.<\/li>\n\n\n\n<li><strong>Waterproofing of roofs<\/strong> in residential or commercial buildings.<\/li>\n<\/ul>\n\n<p><\/p>\n\n<p>Want to see real examples? At <a href=\"https:\/\/www.impera.cat\">IMPERA.cat<\/a> , you can find recent projects with asphalt sheeting on industrial roofs in <strong>Girona<\/strong> , <strong>Barcelona<\/strong> and <strong>the Balearic Islands.<\/strong><\/p>\n\n<p><\/p>\n\n<h4 class=\"wp-block-heading\">What is liquid waterproofing?<\/h4>\n\n<p><\/p>\n\n<p><strong>Liquid waterproofing<\/strong> consists of applying a fluid coating (usually made of polyurethane, epoxy or acrylic resins) that forms a continuous and flexible membrane once it dries.<\/p>\n\n<p><\/p>\n\n<h5 class=\"wp-block-heading\">Advantages of liquid waterproofing:<\/h5>\n\n<p><\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>Application on irregular surfaces<\/strong> or with many construction details.<\/li>\n\n\n\n<li><strong>It leaves no joints or joints<\/strong> , which reduces the risk of leaks.<\/li>\n\n\n\n<li><strong>Ideal for occasional repairs or rehabilitation of old roofs<\/strong> .<\/li>\n\n\n\n<li><strong>Thickness reduction<\/strong> : provides protection without raising the level of the pavement too much.<\/li>\n<\/ul>\n\n<p><\/p>\n\n<h5 class=\"wp-block-heading\">Common applications:<\/h5>\n\n<p><\/p>\n\n<ul class=\"wp-block-list\">\n<li>Roofs with complex geometries.<\/li>\n\n\n\n<li>Interior patios, balconies and galleries.<\/li>\n\n\n\n<li>Reservoirs, canals, areas with permanent water.<\/li>\n\n\n\n<li><strong>One-off interventions<\/strong> to repair local leaks or leaks.<\/li>\n<\/ul>\n\n<p><\/p>\n\n<p>At <a href=\"https:\/\/impera.cat\/en\/\"><strong>IMPERA.cat<\/strong><\/a> , we offer approved liquid systems for quick actions on <strong>terraces of private homes<\/strong> or <strong>roofs of companies<\/strong> with minimal interruptions.<\/p>\n\n<p><\/p>\n\n<h4 class=\"wp-block-heading\">How to choose the best waterproofing system?<\/h4>\n\n<p><\/p>\n\n<p>Each project has its own particularities. The most important thing is to assess:<\/p>\n\n<p><\/p>\n\n<ol class=\"wp-block-list\">\n<li><strong>Surface type<\/strong> : flat, inclined, irregular.<\/li>\n\n\n\n<li><strong>Use of the area<\/strong> : passable or not passable.<\/li>\n\n\n\n<li><strong>Climate<\/strong> : in coastal areas such as the Costa Brava or the Balearic Islands, salinity can affect the durability of materials.<\/li>\n\n\n\n<li><strong>Speed \u200b\u200bof execution<\/strong> : liquid systems are ideal when you need to act quickly.<\/li>\n\n\n\n<li><strong>Overall cost and maintenance<\/strong> : Sheets may be cheaper for large surfaces, but liquids can reduce maintenance costs in the long term.<\/li>\n<\/ol>\n\n<p><\/p>\n\n<p>That is why at <strong>IMPERA<\/strong> we personally advise each client, offering a <strong>professional diagnosis and a tailored proposal<\/strong> . Our technical team works in both <strong>Catalonia and the Balearic Islands<\/strong> , adapting each project to local conditions.<\/p>\n\n<p><\/p>\n\n<h4 class=\"wp-block-heading\">What does the regulation say?<\/h4>\n\n<p><\/p>\n\n<p>According to the <a href=\"https:\/\/www.codigotecnico.org\/\">CTE (Technical Building Code)<\/a> , waterproofing systems must guarantee the tightness of roofs throughout their useful life. It is also indicated that it is necessary to choose systems with CE marking, test certifications and predictive maintenance according to the intended use.<\/p>\n\n<p>At IMPERA we only work with <strong>certified products and approved systems<\/strong> , such as <strong>polyurethane resins and SBS sheets with fiberglass or polyester reinforcement<\/strong> , thus guaranteeing the highest quality in each intervention.<\/p>\n\n<p><\/p>\n\n<h4 class=\"wp-block-heading\">Practical cases in Catalonia and the Balearic Islands<\/h4>\n\n<p><\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>Waterproofing a roof in Girona<\/strong> with double-layer asphalt sheeting, with incorporated thermal insulation.<\/li>\n\n\n\n<li><strong>Renovation of a roof in Ibiza<\/strong> with a two-component polyurethane liquid system applied with a non-slip finish, ideal for withstanding salinity and the marine climate.<\/li>\n\n\n\n<li><strong>Emergency action in Barcelona<\/strong> for leaks in an attic: intervention within 24 hours with a liquid system with integrated fiber.<\/li>\n<\/ul>\n\n<p><\/p>\n\n<p>These types of cases allow us to demonstrate that there is no universally best system, but rather an ideal system for each situation.<\/p>\n\n<p><\/p>\n\n<h4 class=\"wp-block-heading\">Service throughout the territory<\/h4>\n\n<p><\/p>\n\n<p>Many companies only work in small areas, but at IMPERA we offer comprehensive services <strong>throughout Catalonia and the Balearic Islands<\/strong> , both for <strong>individuals, companies<\/strong> and <strong>neighborhood communities<\/strong> . We work quickly and with minimal impact for the client.<\/p>\n\n<p><\/p>\n\n<h4 class=\"wp-block-heading\">Asphalt or liquid sheet?<\/h4>\n\n<p><\/p>\n\n<p>It depends on your project. If you need a robust solution, with high resistance and quick application on large flat surfaces, asphalt sheeting may be the best option. If, on the other hand, you have a complex space, you need to act quickly or a one-time repair is required, liquid waterproofing will provide you with more flexibility and tightness.<\/p>\n\n<p><\/p>\n\n<p>In all cases, the most important thing is to have specialized professionals who know how to adapt the system to your specific case.<\/p>\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>When it comes to protecting a building from moisture and leaks, the choice of waterproofing system is key.
