Will this ensure that no leakage occurs for the next five years or more?"},"content":{"rendered":"<p class=\"wp-block-paragraph\">Answer:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">After the roof waterproofing work is completed, a trial run is conducted first; this is a necessary procedure, but it still cannot ensure that no water leakage will occur in the next five years or more, because:<br><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">(1) PU itself is a waterproof material; when it gets wet, it acts like water being poured into a plastic bucket; of course, it cannot leak water. The key factor in ensuring that the roof remains waterproof for a long time is the quality of the construction work on corners, joints, cracks in the floor, around pipes, and other critical areas; these defects cannot be revealed in a short period of time; they must be exposed over a period of time through testing by sun, rain, and earthquakes before the true nature can be revealed.<br>(2) The long-term quality and performance of PU waterproof coatings depend on whether the thickness is sufficient, the formulation is appropriate, the primer is applied properly, and the quality of the material is good (not using inferior materials to make up for shortcomings). These factors cannot be observed in a matter of days of trial and error.<br>(3) Ensuring that the PU waterproofing has a lifespan of more than five years requires not only the determination of the brand, name, thickness, and construction specifications before the contract is awarded, but also the supervision during the construction process. Relying solely on a few days of water-logging tests is meaningless.<\/p>","protected":false},"excerpt":{"rendered":"<p>\u7b54\uff1a \u5c4b\u9802\u9632\u6c34\u65bd\u4f5c\u5b8c\u7562\u5148\u884c\u8a66\u6c34\uff0c\u9019\u662f\u5fc5\u8981\u7684\u624b\u7e8c\uff0c\u4f46\u4ecd\u7136\u7121\u6cd5\u78ba\u4fdd\u65e5\u5f8c\u4e94\u5e74\u4ee5\u4e0a\u4e0d\u518d\u767c\u751f\u6f0f\u6c34\u73fe\u8c61\uff0c\u56e0\u70ba\uff1a (1) P [&hellip;]<\/p>\n","protected":false},"author":4,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[24],"tags":[70],"class_list":["post-8890","post","type-post","status-publish","format-standard","hentry","category-100qa","tag-qa"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.daisin.com.tw\/en\/wp-json\/wp\/v2\/posts\/8890","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.daisin.com.tw\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.daisin.com.tw\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.daisin.com.tw\/en\/wp-json\/wp\/v2\/users\/4"}],"replies":[{"embeddable":true,"href":"https:\/\/www.daisin.com.tw\/en\/wp-json\/wp\/v2\/comments?post=8890"}],"version-history":[{"count":0,"href":"https:\/\/www.daisin.com.tw\/en\/wp-json\/wp\/v2\/posts\/8890\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.daisin.com.tw\/en\/wp-json\/wp\/v2\/media?parent=8890"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.daisin.com.tw\/en\/wp-json\/wp\/v2\/categories?post=8890"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.daisin.com.tw\/en\/wp-json\/wp\/v2\/tags?post=8890"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
