                非沥青基防水卷材铺设有哪些技巧 


                非沥青基防水卷材在铺设过程中也是有一些技巧的,可以提升工作效率,下面非沥青基高分子自粘防水胶膜带大家一起来了解一下。  

                非沥青防水卷材铺设在底板和侧墙,阴阳角部位加强层铺设完毕后进行,施工顺序为先做承台、基梁、底板,后侧墙,底板从南往北纵向铺设,侧墙自下向上铺设。靠近底板垫层和地连墙面一侧为非粘结面(PE面),与结构外表面密贴面为有隔离□ 面(粘贴面)。  

                侧墙防水层采用机械固定法固定于围护墙表面,固定点距卷材边缘1-2cm,钉距不大于30cm,钉长不得小于30mm,且配合垫片将防水层牢固的固定在基层表面,垫片直径不小于20mm,厚度不小于1mm,底板除阴阳角等特殊部位需要机械固定外,大面防水层〗可直接搭接,相邻两幅卷材的长边采用卷材的自粘层进】行搭接,搭接宽度为100mm。
