建筑防水还要设计吗?不就是一道防水层么。二十年前这么说是对的,想当年中国只有一种纸胎沥青毡(俗称油毡),除此别无可选。凡须做防水的地方,就是三毡四油。博物馆防水三毡四油;厂房防水三毡四油;住宅防水也是三毡四油;水池、厕浴间防水,还是三毡四油。一种防水材料包打天下,所以建筑师无须作防水设计亦未尝不可,而且防水施工有规范,工人师徒相传,操作熟练,不用图纸也能施工。现在不可昔比,防水材料发展很快,有卷材、有涂料,还有刚性防水;有合成高分子、有改性沥青,还有外加剂防水;有液状的、有膏状的,还有粉状的,真是五花八门,品种繁多,使你眼花缭乱,不知选哪种好。
Is building waterproofing designed? Isn’t it a waterproof layer? Twenty years ago it was right to say that there was only one type of asphalt felt for tar (commonly known as linoleum) in China, but there was no alternative. Wherever waterproofing is required, three felts and four oils are used. Museum waterproof three felt four oil; plant waterproof three felt four oil; residential waterproof is also three felt four oil; pool, toilet and bathroom waterproof, or three felt four oil. A kind of waterproof material is used to wrap the world, so architects do not need to make waterproof design, and it is not a bad idea. Besides, there is a standard for waterproof construction. The workers are masters and teachers, skilled in operation, and can work without drawings. Nowadays, unlike in the past, waterproof materials have developed rapidly, with coils, coatings, and rigid waterproof; synthetic polymers, modified asphalt, and additives for waterproofing; liquid, paste-like, and Powdery, really varied, variety, so that you dazzled, I do not know what to choose good.
