二层露天平台防水工程施工工艺收集资料

1、谢谢你的观赏二层露天平台防水工程施工工艺收集资料1第二层露天平台防水工程施工工艺，程序须知1 原楼板填缝，各坑洼处抹平。（作用：节约防水材料）2 地脚线位置，开凿凹进2cm。 （柔性防水材料，必须用沙浆覆盖）3 地面除灰尘，沙粒。并且楼面须干燥一天。（增加防水的附着性）4 采用有弹性的沥青油材料，滚涂仔细不留死角。（弹性须适应南非约翰内斯堡的昼夜巨大温差，不发生脆裂）5 在沥青油防水层上，覆盖纤维布。6 在纤维布上再重复滚涂沥青材料一次。（增加强度和防水性能）7 覆盖塑料薄膜膜后。做7 天闭水试验。不漏水，成功防漏后，进入下一步工序。（及时发现并整改，减少更大的损失）8 膜上铺设钢丝网，轻拿轻

2、放，保护好防水层。用沙浆做走水坡面面。保证有5cm 落差。落水口为两110 管。（不积水，雨水流走快速）9 干燥后，在走水坡面上涂刚性聚合物防水剂。（防止砂浆层存水。注意：室内浴室防水只需此道工序）10 铺设地砖，留0.5cm 砖缝。用膨胀性水泥填缝。The first floor open platform waterproof project construction process, program instructions1 original floor seam filling, each place certainly some pits. Function: save (wate

3、rproof material),2 the anchor line position, digging 2cm instead. Flexible waterproofing materials, must (with mortar)3 ground remove dust, sand. And the floors shall be dry. (the adhesion) increased waterproof4 using elastic material, coating of asphalt oil not carefully. Johannesburg, South Africa

4、 (elastic must adapt to the huge difference does not occur embrittlement),5 oil in asphalt waterproof, covering fiber cloth.6 in fiber cloth repeat roll asphalt material. (to increase the intensity and waterproof properties),7 cover plastic membrane. Do 7 days shutting water test. Don't slack, leakproof, after the successful entering the next procedure. Timely discovery and rectification, (reduction greater loss),8 the laying of steel wire, membrane gently with good protection of waterproof. Do everything with mortar don slope. Ensure 5cm ga
