1、施工准备
1.1防水材料选用和准备
1.1.1一般选用高强度、低延伸的防水卷材，应结合工程的实际情况，选用3㎜厚的Ⅱ类拉力≥400N、延伸率≥5%的黄麻胎体SBS改性沥青防水卷材。
节点附加层应选用氯丁橡胶改性沥青防水涂料，要求固体含量≥43%，延伸≥4.5㎜，耐热度为80℃时5h无流淌、起泡。
密封材料选用SBS改性沥弹性密封膏，粘结性≥15㎜，耐热度下垂≤4㎜。
1.1.2防水材料的质量要求
所用的SBS卷材改性沥青防水卷材、氯丁橡胶改性沥青防水涂料、SBS改性沥青弹性密封膏等均必须有出厂合格

1, construction preparation
1.1 Selection and preparation of waterproof materials
1.1.1 General use of high strength, low extension of the waterproofing membrane, the project should be combined with the actual situation, using 3 mm thick, Class Ⅱ pull ≥ 400N, elongation ≥ 5% of the jute matrix SBS modified bitumen membrane.
Node should use an additional layer of neoprene modified asphalt waterproofing coating, required solid content ≥ 43%, extension of ≥ 4.5 mm, heat degree is 80 ℃, 5h free flowing, bubbling.
SBS modified asphalt sealing material used flexible sealant, bonding of ≥ 15 mm, ≤ 4 mm ptosis degree heat.
1.1.2 Water quality requirements of materials
Membrane used in SBS modified bitumen membrane, chloroprene rubber modified asphalt waterproofing coating, SBS modified bitumen flexible sealant Dengjun must have factory qualified
