However, just two years after moving in, the terrace began leaking, necessitating a comprehensive waterproofing renovation.<\/p>\n<p><img decoding=\"async\" alt=\"image\" src=\"https:\/\/www.anjuparts.com\/wp-content\/uploads\/2025\/11\/v2-799a47f8bd621dfa890e31bac044a193_720w-1.webp\"><\/p>\n<p>With guidance from a recommended professional, I followed a method that promises leak-free performance for up to 20 years. The process involved multiple steps: First, remove any existing waterproofing and insulation to expose the concrete structure. If there are pipes or electrical conduits, apply a leveling layer with a slope toward the drainage outlet to protect them during construction.<\/p>\n<p><img decoding=\"async\" alt=\"image\" src=\"https:\/\/www.anjuparts.com\/wp-content\/uploads\/2025\/11\/v2-286e280c4f67ec2b9fdee1ff6287f7ad_720w-1.webp\"><\/p>\n<p>Next, address\u7ec6\u8282 at wall corners using polyester fabric and white waterproof mortar for a three-coat application to prevent cracking. Create slopes in corners to avoid water accumulation.<\/p>\n<p><img decoding=\"async\" alt=\"image\" src=\"https:\/\/www.anjuparts.com\/wp-content\/uploads\/2025\/11\/v2-9d7003ead222ed6cfe278845ba63148b_720w-1.webp\"><img decoding=\"async\" alt=\"image\" src=\"https:\/\/www.anjuparts.com\/wp-content\/uploads\/2025\/11\/v2-6691d5ecb34fa0fb5eeca73f5da8d147_720w-1.webp\"><\/p>\n<p>Then, apply a cold primer evenly and let it dry for at least 4 hours before using rubberized asphalt coating on high-risk areas like wall roots and corners for enhanced protection.<\/p>\n<p><img decoding=\"async\" alt=\"image\" src=\"https:\/\/www.anjuparts.com\/wp-content\/uploads\/2025\/11\/v2-3f9eb45bf127f0f532eae6d5a45a22c6_720w-1.webp\"><\/p>\n<p>For waterproof membrane installation, start with an additional layer in critical zones using a heat-welding method with over 20cm width to meet standards. Fully adhere and weld the membrane with 10cm overlaps, followed by a 24-hour water test for leaks.<\/p>\n<p><img decoding=\"async\" alt=\"image\" src=\"https:\/\/www.anjuparts.com\/wp-content\/uploads\/2025\/11\/v2-adf3392e7dc08f6c267f4c7af8cfb2df_720w-1.webp\"><\/p>\n<p>Add insulation: use an air gap for non-walkable areas and 5cm thick extruded polystyrene boards for terraces. Finish with a cement mortar protective layer, leveling with a slope, and install tiles or wooden flooring.<\/p>\n<p><img decoding=\"async\" alt=\"image\" src=\"https:\/\/www.anjuparts.com\/wp-content\/uploads\/2025\/11\/v2-5453572cf1c577833d9285347fe05feb_720w-1.webp\"><img decoding=\"async\" alt=\"image\" src=\"https:\/\/www.anjuparts.com\/wp-content\/uploads\/2025\/11\/v2-1899092b7ba92ad5212e1d305e348ea4_720w-1.webp\"><img decoding=\"async\" alt=\"image\" src=\"https:\/\/www.anjuparts.com\/wp-content\/uploads\/2025\/11\/v2-ffd384066bb674942cadb0136068b30d_720w-1.webp\"><\/p>\n<p>This approach has proven reliable over five years, with expectations of lasting two decades, and costs around 110 per square meter, making it a cost-effective solution.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Expert Guide to Waterproofing Top-Floor Terraces: Step-by-Step Process for 20-Year Leak Protection and Durability in Apartment Renovations<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[1880,1878,1876,1855,1877,1879,1873,1875,1872,1874],"class_list":["post-3933","post","type-post","status-publish","format-standard","hentry","category-uncategorized","tag-apartment-maintenance","tag-cost-effective-solution","tag-diy-renovation-guide","tag-leak-prevention","tag-long-term-durability","tag-step-by-step-process","tag-terrace-waterproofing","tag-thermal-insulation","tag-top-floor-apartment","tag-waterproof-membrane-installation"],"_links":{"self":[{"href":"https:\/\/www.anjuparts.com\/index.php\/wp-json\/wp\/v2\/posts\/3933","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.anjuparts.com\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.anjuparts.com\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.anjuparts.com\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.anjuparts.com\/index.php\/wp-json\/wp\/v2\/comments?post=3933"}],"version-history":[{"count":0,"href":"https:\/\/www.anjuparts.com\/index.php\/wp-json\/wp\/v2\/posts\/3933\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.anjuparts.com\/index.php\/wp-json\/wp\/v2\/media?parent=3933"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.anjuparts.com\/index.php\/wp-json\/wp\/v2\/categories?post=3933"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.anjuparts.com\/index.php\/wp-json\/wp\/v2\/tags?post=3933"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
