房屋滲漏是建筑工程中的主要質量通病之一，外墻易產生滲漏的部位主要有門窗與外墻交接部位滲水、散水坡滲水、外墻預埋件根部滲水、變形縫部位滲水、外墻鑲貼飾面塊材滲漏、鋁合金門窗的滲漏。外墻滲漏的大部分原因，多為施工措施不當及施工工藝不到位所產生的后果。下面濟南專業防水公司給大家介紹幾種預防外墻滲漏的方法。
1、變形縫內嚴禁掉入砌茬、砂漿和其他雜物，縫內應保持干凈、貫通，按規范要求填油麻絲外加蓋鍍鋅鐵板。密閉鍍鋅蓋板的制作應符合變形縫工作構造要求，確保沉降、伸縮的正常性。安裝蓋板必須整潔、平整、牢固，接頭處必須是順水方向壓接密實。
Do not fall into the puzzle within Deformation stubble, mortar and other debris should be kept clean and the seam, through, according to specifications flax oil to fill the outer stamped galvanized iron. Sealed cover made of galvanized movement joint work should be consistent with structural requirements to ensure the settlement, retractable normal sex. Install the cover must be clean, smooth, firm, joints must be sailing direction crimp dense.
2、鋁合金窗框的下擋應設排水孔，窗框陰角密封膠應嵌實封閉。榫接、螺釘等處都應仔細嵌上耐候膠。毛刷條玻璃嵌條、固定牢固，安裝到位，無短頭、缺角、離位現象，耐候膠應光滑平整，粗細均勻無氣泡。窗扇與窗框搭接嚴密，關閉后應無縫隙，不透氣不透亮不滲水。
Under the aluminum window frames blocked drainage holes should be located, sash overcast corner sealant should be caulked closed. Mortise, screws, etc. should be carefully embedded on weathering plastic. Brush strip of glass moldings, fixed firmly in place, no short head, chipping, off-site phenomenon, weathering plastic should be smooth, uniform thickness, no bubbles. Lap sash and frame tight, there should be no gap closed, airtight not translucent impermeable.
3、外墻框架結構柱與砌體圍護結構間的連接，必須按設計及施工規范要求，在混凝土柱中預埋砌體錨固鋼筋;在砌體結構施工前，柱與砌塊必須澆透水，吸水飽滿。砌筑時，砌體與柱間必須用同標號的砌筑砂漿填塞飽滿，不得出現先砌磚后鉤縫的現象。在結構梁面砌筑砌體時，必須座漿飽滿。
Connection columns and masonry exterior frame structure between the envelope must be according to the design and construction specifications, embedded in masonry anchor reinforced concrete column; masonry structure before construction, column and block must be irrigated water full. When masonry must be packed full with the same label mortar between masonry and columns may not appear after the first brick hook sewn phenomenon. When masonry masonry surface structural beams must seat pulp full.
4、窗臺施工時室外應低于室內20mm，做成順水坡。窗楣設置滴水槽，或做成鷹嘴。室外窗臺飾面層應嚴格控制水泥砂漿的水灰比，抹灰前充分濕潤基層，并涂刷素漿結合層，薄厚均勻一致，抹灰抹壓密實，下框企口嵌灰飽滿密實、壓嚴。
When windowsill construction should be below indoor outdoor 20mm, made ??sailing slope. Window lintel set drip, or make olecranon. Outdoor windowsill facing layer of cement mortar should be strictly controlled water-cement ratio, fully wet grass before plastering and brushing prime pulp binding layer, thickness uniform, plastering TROWELING dense, gray inlay under the tongue and groove box full of dense, press Yan.
5、散水坡的基底應夯實或采用中砂、爐渣的材料，墊層應采用碎石混凝土，防止不均勻沉降造成散水坡開裂。散水坡應從墊層到找平層和面層與墻身勒腳斷開，防止建筑物沉降時破化散水結構的整體性。且要按房屋建筑軸線設置溫度縫，防止因溫度變化造成散水坡伸縮而損壞散水坡。
Bulk water slope of the base should be compacted or use sand, slag materials, concrete gravel cushion should be used to prevent bulk water caused by uneven settlement slope cracking. Bulk water slope should cushion the leveling layer and the surface layer and the wall plinth disconnected, to prevent breaking the integrity of the bulk water structure when building settlement. And set the temperature according to the axis of housing construction joints, prevent bulk water due to temperature changes caused by damage to the slope stretching bulk water slope.
