　　1、技能(neng)預備：屋(wu)面工(gong)(gong)(gong)(gong)程(cheng)(cheng)(cheng)施(shi)(shi)(shi)工(gong)(gong)(gong)(gong)前，施(shi)(shi)(shi)工(gong)(gong)(gong)(gong)單位應(ying)組織技能(neng)管理人員會審屋(wu)面工(gong)(gong)(gong)(gong)程(cheng)(cheng)(cheng)圖紙，掌(zhang)握(wo)施(shi)(shi)(shi)工(gong)(gong)(gong)(gong)圖中的細部結構及有關技能(neng)要求(qiu)并(bing)根據工(gong)(gong)(gong)(gong)程(cheng)(cheng)(cheng)的實際(ji)情(qing)況編制屋(wu)面工(gong)(gong)(gong)(gong)程(cheng)(cheng)(cheng)的施(shi)(shi)(shi)工(gong)(gong)(gong)(gong)方(fang)案或(huo)技能(neng)措施(shi)(shi)(shi)。這樣防(fang)止施(shi)(shi)(shi)工(gong)(gong)(gong)(gong)后留下缺點，形成返(fan)工(gong)(gong)(gong)(gong)，一起工(gong)(gong)(gong)(gong)程(cheng)(cheng)(cheng)根據施(shi)(shi)(shi)工(gong)(gong)(gong)(gong)組織有計劃地打(da)開施(shi)(shi)(shi)工(gong)(gong)(gong)(gong)，防(fang)止作(zuo)業遺漏、紊亂、倒置影(ying)響工(gong)(gong)(gong)(gong)程(cheng)(cheng)(cheng)質量。

　　2、施工要求：屋面工程的防水必須由防水專業隊伍或防水工施工，禁止沒有資質等級證書的單位和非防水專業隊伍或非防水工進行屋面工程的防水施工，建設單位或監理公司應認真地檢查施工人員的上崗證。施工中施工單位應按施工工序、層次進行質量的自檢、自查、自糾并且做好施工記錄，監理單位做好每步工序的驗收作業，驗收合格后方可進行下道工序、層次的作業。
　　3、防水材料質量(liang)：屋(wu)(wu)面工程(cheng)所選用的防水材料應有(you)(you)材料質量(liang)證明文件，并經指(zhi)定(ding)質量(liang)檢測部分(fen)認證，確保(bao)其質量(liang)契(qi)合《屋(wu)(wu)面工程(cheng)技(ji)能規(gui)(gui)范(fan)》（GB50207—94）或國家有(you)(you)關(guan)規(gui)(gui)范(fan)的要求。防水材料進入施(shi)工現(xian)(xian)場(chang)后(hou)應附有(you)(you)出廠查(cha)驗(yan)(yan)報(bao)告(gao)單(dan)(dan)及出廠合格(ge)證，并注明生產日期(qi)、批號、規(gui)(gui)格(ge)、名(ming)稱。施(shi)工單(dan)(dan)位(wei)應按規(gui)(gui)定(ding)取樣(yang)復檢，取樣(yang)復檢嚴厲依照(zhao)見(jian)證取樣(yang)送樣(yang)準則，在(zai)建設單(dan)(dan)位(wei)代表或監(jian)理單(dan)(dan)位(wei)人員見(jian)證下，由施(shi)工人員在(zai)現(xian)(xian)場(chang)抽(chou)樣(yang)，送到實(shi)驗(yan)(yan)室進行實(shi)驗(yan)(yan)。經復檢合格(ge)，提交復檢實(shi)驗(yan)(yan)報(bao)告(gao)合格(ge)單(dan)(dan)后(hou)方可(ke)在(zai)防水工程(cheng)中(zhong)使(shi)用。

　　4、環境要求：為了保證施工操作以及卷材鋪貼的質量，宜在+50C~+350C氣溫下施工；高聚物改性瀝青以及高分子防水卷材不宜在負溫以下施工，熱熔法鋪貼卷材可以在-100C以上的氣溫條件下施工，這種卷材耐低溫，在負溫下不易被凍壞。雨、雪、霜、霧，或大氣濕度過大，以及大風天氣均不宜露天作業，否則應采取相應的技能措施。
　　5、排(pai)水斜(xie)(xie)(xie)度(du)(du)：平屋面的(de)排(pai)水斜(xie)(xie)(xie)度(du)(du)為2%~3%，當斜(xie)(xie)(xie)度(du)(du)小(xiao)于等于2%時(shi)，宜選用材料找坡(po)；當斜(xie)(xie)(xie)度(du)(du)大于3%時(shi)，宜選用結構找坡(po)。天溝(gou)、檐溝(gou)的(de)縱向斜(xie)(xie)(xie)度(du)(du)不(bu)該小(xiao)于1%，溝(gou)底落差(cha)不(bu)得超越200mm。水落口周圍(wei)直徑500mm范(fan)圍(wei)內斜(xie)(xie)(xie)度(du)(du)不(bu)該小(xiao)于5%。
