| 随着我国建筑业的发展，防水材料与防水施工技术也相继发展，材料标准和施工规程规范的修制定工作也越来越规范。因此，与国外同行的技术交流也日益增多，国外的先进技术和经验，频频为我国防水行业所应用。 With the development of China's construction industry, the waterproof materials and waterproof construction techniques have also been developed, and the construction work of material standards and construction regulations is becoming more and more standardized. Therefore, the technical communication with foreign counterparts is also increasing, and the advanced technology and experience abroad are frequently used in China's waterproof industry. 一、日本的防水工程设计与施工 I. design and construction of waterproof engineering in Japan 中国建筑方案设计与施工图设计均由业主委托专业设计院所设计，在施工图完成后进行招投标，其中防水材料的选用、防水构造的设计均在设计图中明确。而日本工程招投标实行国际惯例，以设计事务所设计的方案作为招投标基本文件。方案图中，设计师对需要防水的部位提出了防水要求，但没有具体构造及选材。施工图是在投标人中标后，由总承包商根据业主招标方案进行设计，确定具体材料的选用及构造。施工图设计过程中，专项工艺由总承包商进行二次招投标，以完成工程实施详图，确定专项工艺的技术、材料及构造，其中防水工程就是通过二次招标过程来确定的。这样的防水设计具有很强的针对和设计施工的同一性。 China architectural design and construction drawing design are designed by owner entrust professional design institutes, after completion of the construction drawing for bidding, including the selection of waterproof material, waterproof structure design are clear in the drawings. And the Japanese engineering bidding practice international practice, design the design of the design of the plan as the basic documents. In the plan diagram, the designer made waterproof requirements for the parts that needed to be waterproof, but there was no specific construction or selection. The construction drawing is designed by the general contractor according to the owner's bidding plan after winning the bid, and determines the selection and construction of the specific material. In the process of the construction drawing design, special process conducted by the general contractor bidding, to complete the project implementation details, to determine the special process technology, material and structure, the waterproof engineering is through the second bidding process to determine. Such waterproof design has a strong identity for design and construction. 1、日本的防水工程造价和结算 1. Japan's waterproofing project cost and settlement 总包招标时，以总造价的10%左右预计防水工程造价，包括建筑物的屋面、地下、卫生间防水等。总包方在施工图设计阶段对防水工程招标时，从技术上由总包方提出要求，投标人根据各自技术特点提供方案，造价上总包方以投标时的10%总造价作为控制依据。由于业主的监督和总包方对工程质量的责任心，通常防水造价能够控制在10%左右，不会有大幅度的下降。防水施工企业与总承包商签订承包协议后，严格按照合同施工及根据合同约定支付工程款。不存在催讨工程款问题。 When the total package is tendered, it is estimated that the cost of waterproofing works will be estimated at about 10% of the total cost, including the roof of the building, the underground, the bathroom and so on. The total package party of waterproof engineering bidding in construction drawing design stage, from the technical request, by the contractor on the bidder to provide solutions based on the characteristics of each technology, cost 10% of the total package party to bid on the total cost control as the basis. Due to the owner's supervision and the total contractor's responsibility for the quality of the project, the waterproof cost can be controlled at about 10%, and there will be no significant decline. After signing the contract agreement with the general contractor, the waterproof construction enterprise shall pay the project money strictly in accordance with the contract construction and the contract agreement. There is no question of asking for a project. 2、日本的防水工程保证、保修期 2. Japan's waterproof engineering guarantee and warranty period 日本没有防水工程保证期这么一说，也没有对防水工程规定保修年限。日本企业很注重信誉，对待工程都是精益求精，各工种严格按照设计及工艺要求认真施工，通常不会出现渗漏现象。但由于防水质量的保证涉及多方面因素，责任很难确定。一旦出现渗漏，由防水施工企业进行修补，费用由总承包商承担，因此不存在保修金问题。 There is no guarantee period for waterproofing in Japan, and there is no guarantee period for waterproof works. Japanese companies pay close attention to the credibility, treat the project all the best, each work is strict according to the design and the process demands serious construction, usually does not have the leakage phenomenon. But because the guarantee of waterproof quality involves many factors, it is difficult to determine the responsibility. Once the leakage occurs, the waterproof construction enterprise shall be repaired and the expenses shall be borne by the general contractor, so there shall be no warranty issues. 在日本还有一种情况就是总承包商或业主要求对防水质量进行合同保证，那么防水工程企业在施工报价时，增加20%-30%的风险金，保修期为3-5年，一旦出现渗漏，由防水施工企业进行免费修补。 In Japan there is a kind of situation is general contractor or owner requires a contract to ensure quality of waterproof, waterproof engineering companies in the construction price, increased by 20% - 30% of the risk fee, the warranty period for 3 to 5 years, once appear leakage, repair free of charge by waterproof construction enterprises. 3、日本的防水施工企业资质要求 3. Qualification requirements of Japanese waterproof construction enterprises 日本对防水施工企业没有资质要求。防水工程企业作为普通企业进行注册营业，由国土交通省颁发许可证。信誉是一个企业的生命，为了承接到更多的工程，防水工程企业必须有一个很好的社会信誉如果完工的防水工程经常渗漏，需要返工，那么这个施工企业的生存就存在问题了。以后在社会上就接不到工程了。 Japan has no qualifications for waterproof construction enterprises. Waterproofing engineering enterprises shall be registered as ordinary enterprises and shall be issued by the ministry of land and transport. Credibility is the life of an enterprise, in order to carry on to the more engineering, waterproof construction enterprises must have a good social reputation if completion of waterproof engineering seepage, often need to rework, so the construction enterprise survival problems. In the future, we won't be able to get the project. 为了使企业能承接复杂和重要的防水工程，企业必须配有高等级的注册建筑师和工程师等技术人员，有专门的设计部门进行防水工程设计，操作工人也是相对固定的。一切配备都是由企业自己决定。 In order to make the waterproof construction enterprises can undertake complex and important, enterprises must be equipped with first-class registered architects and engineers and other technical personnel, have special waterproof engineering design department, operating workers is relatively fixed. All the equipment is decided by the enterprise itself. 二、（BUR）沥青屋面系统 2. (BUR) asphalt roofing system 沥青屋面系统在欧美和日本，仍具有竞争力。主要是，一个维护良好的热施工叠层屋面系统，可以使用20年或更长。另外，在严酷的气候条件下，BUR系统总的质量要比单层屋面系统大得多，因而BUR系统抗风揭性好，不易被风吹起、不易被物体刺破同时，BUR系统中层与层之间通过液体沥青结合在一起，形成一个整体，在完工的屋面中，实际上不存在任何接缝，也就消除了接缝这一薄弱环节。 The asphalt roofing system is still competitive in Europe, America and Japan. Mainly, a well-maintained thermal construction laminated roof system can be used for 20 years or more. In addition, in the harsh climate conditions, BUR system overall quality are much larger than single roof system, thus good wind jie BUR system, not easily by the wind, not easily be object to Pierce at the same time, BUR system between middle and layer through liquid asphalt together, form a whole, in the completion of roofing, actually there is no juncture, also eliminates the seam the weak links. 此外，当沥青直接涂在结构混凝土屋面板上或涂在保温屋面板上时，可认为整个屋面是一个全粘系统，而这种全粘系统的一大好处，是能分布建筑物受到的应力(如风荷载、振动和弯曲)。热沥青施工，采用现代的设备控制沥青温度、粘度以及烟气的排放，既能保护环境，又能提高施工质量。 In addition, when the asphalt coating on the structural concrete roof board directly or coated on the BaoWenWu panel, the entire roof can be thought of as a whole glue system, and the great thing about this whole stick system, is the ability to buildings by stress (wind load, vibration and bending). The construction of hot asphalt, using modern equipment to control the asphalt temperature, viscosity and the emission of flue gas, can both protect the environment and improve the construction quality. 三、匈牙利的防水工程 Iii. Waterproof engineering in Hungary 匈牙利防水技术人员享承欧洲人的严谨作风，注重细节，训练有素，工法熟练，结合不同部位，运用多种材料构成系统防水，值得学习和借鉴。 Hungary waterproof technology personnel at europeans rigorous style of work, pay attention to details, well trained, can skilled, combining with the different parts, using a variety of waterproof material composition system, worth learning and using for reference. 1、屋面防水 1. Roofing waterproof 选用PVC卷材，分为暴露型和非暴露型。全部采用机械固定，接缝采用热风焊接施工工艺。施工技术非常讲究，所有阴阳角、女儿墙、落水孔、排气管等部位，都做附加层上下层卷材搭接，卷材的直角都剪成圆角所有接缝处全部用密封胶封边非上人屋面部分的维修道和避雷线支撑点下面都用双层增强做法，避免磨损造成渗漏。 PVC rolls are used to be classified as exposed and non-exposed. All adopt mechanical fixation, the joints adopt hot wind welding construction technology. Construction technology is very exquisite, all Angle, parapet, down hole of Yin and Yang, the exhaust pipe and other parts, do additional layer on the lower layer coil lap, coil right Angle are cut into rounded all the seams with sealant sealing side of master cheng yen roof part maintenance and ground wire points below with double strength, avoid wear and tear caused by leakage. 2、天台的种植屋面的构造 2. The structure of roof planting roof 其构造层次由上而下分别为4mm厚铝箔胎SBS 改性沥青防水卷材隔气防水层、岩棉保温层、PVC防水卷材耐根防水层、HDPE排水板、聚醋无纺布隔土层、种植土及植物，用聚苯保温板做找坡通过排水板使水汇集到集水口，经过内天沟把水排出。 The top-down construction level respectively 4 mm thick aluminum foil tire SBS modified asphalt waterproof coiled material gas insulation waterproof layer, rock wool insulation layer, PVC waterproofing materials resistant to root the waterproof layer, HDPE drainage plate, vinegar non-woven every soil layer, soil and plant, made from polystyrene insulation board for slope through drain the water to set shuikou, after installed in the water. 3、地下室顶板种植屋面 3. Basement roof planting roof 选用改性沥青耐根防水卷材双层施工，阴阳角全部做加强层搭接边都剪成，避免出现搭接处太厚现象所有因施工破损的卷材，根据破损面的大小，用四角剪成圆形的卷材片补好，再做第二层 卷材铺设卷材时，先用喷枪将大面积热熔粘好，留出搭接边再专门进行第二次热熔，同时用压辊将搭接边熔化的沥青挤出封边，做工精细。 Choose resistance of modified asphalt waterproofing double-layer construction, strengthening layer overlapping edge Angle all of Yin and Yang are cut into, avoid taking it too thick phenomenon is all because of construction damage of coil, according to the broken surface size, with four corners cut into circular coil mended, do the second floor Laying coil, coil use spray gun first large area hot melt glue, set aside lap to specialise in a second hot melt, at the same time with the roller will lap melting bitumen sealing side, fine workmanship. 4、门窗边框 4. Window frame 所有门窗框与结构墙结合的内外缝隙，全部采用0.8mm厚的三元乙丙卷材裁成的条型泛水粘贴，做到门窗框与结构墙结合的内外缝隙不透水气，以达到良好的防水、节能效果。 All door window frame and structure combination of inside and outside wall, are all made of 0.8 mm thick epdm coiled material cut into strip the water paste, door window frame and structure combination of inside and outside wall impermeable gas, in order to achieve a good waterproof, energy saving effect. 5、外飘走廊和外墙 5. Outer corridors and outer walls 外飘走廊和外墙用0.8mm厚的三元乙丙卷材外贴防水，走廊上用排水板导水到落水口外墙用高强度岩棉保温，外抹1cm~2cm厚的聚合物水泥砂浆，作防水层。 Flare corridor and exterior use 0.8 mm thick epdm coiled material waterproof is stuck outside, the corridor with drain water to the water inlet guide walls with high strength rock wool insulation, wipe out 1 cm ~ 2 cm thick polymer cement mortar, waterproof layer. 四、德国的道桥防水 4. The German road bridge is waterproof 德国的道桥绝大部分是混凝土的，所有的混凝土基面都不做砂浆保护层，基层混凝土的强度为C40，直接用环氧树脂处理和环氧砂浆修补，上面采用单层5mm的APP聚醋胎道桥卷材热熔施工，然后再铺装沥青路面，沥青层分上下两层，下层95%是采用浇注沥青，5%是沥青混凝土，上层可以是浇注沥青或摊铺沥青。在欧洲，当全部采用摊铺沥青施工时，防水采用两层SBS道桥卷材波兰、瑞士采用一层道桥卷材，欧洲其他国家主要采用SBS道桥卷材配合摊铺沥青施工（占95%），70%以上的混凝土层采用环氧树脂做封闭底涂。 German bridge, for the most part is concrete, do all of the concrete base mortar layer, the strength of the concrete at the grass-roots level to C40, with epoxy resin and epoxy mortar directly repair, using single 5 mm above the APP together vinegar tire bridge coil, hot melt construction and paving of asphalt pavement, asphalt layer consists of two layers, the lower is 95% by pouring asphalt, 5% of asphalt concrete, the upper pouring asphalt or paving asphalt. In Europe, when construction are all made of paving asphalt, SBS waterproof adopts two layers of road and bridge USES a layer of bridge coil coil Poland, Switzerland, the rest of Europe mainly adopts the SBS bridge coil with paving asphalt construction (95%), more than 70% of the concrete floor adopts closed bottom coating epoxy resin. 德国很少采用涂料作为道桥防水，因为涂料厚度难以保证，所以，防水涂料如环氧改性聚氨醋主要作为细部节点的防水，但其价格比较高。德国所有的桥梁，无论荷载多少，其防水要求都一样。在施工现场，每500m2耐需要检测粘结性能，工程验收也有严格的现场程序。为了更好地保证工程质量，德国最近正在改进施工方式，如要求卷材施工必须实行机械铺设等等。 Germany rarely used as road and bridge waterproof coating, because the thickness of the coating is difficult to guarantee, therefore, waterproof coating, such as epoxy modified polyurethane vinegar mainly as detail node waterproof, but its price is quite high. All the Bridges in Germany, no matter how much the load, their waterproof requirements are the same. In the construction site, every 500m2 need to detect the bond performance, and the construction inspection has strict on-site procedures. In order to better guarantee the quality of the project, Germany has recently improved its construction methods, such as requiring the construction of rolling materials to be carried out mechanically. 五、国际防水行业发展趋势种植屋面 5. Development trend of international waterproof industry planting roof 1、种植屋面 1. Planting roof 可以通过滤除尘埃来缓解空气污染状况可以湿润干燥的城市空气可以吸附噪音并减少噪声的反射在冬天起到保温作用而夏天起到降温作用，同时避免人口稠密地区“ 热岛效应” 的产生。种植屋面近几年在西欧、美、日等国悄然兴起，方兴未艾，迅速增长。 Can alleviate air pollution by dust filter can be wet, dry air in cities can absorb the reflection noise and reduce the noise insulation effect in winter and summer cooling effect, at the same time avoid the densely populated areas "heat island effect". Planting roof in Western Europe, the United States, Japan and other countries quietly emerged in recent years. 种植屋面一般包括种植层、排水和过滤层、分离层、防水阻根层、保湿层、蒸汽阻拦层、基层等，其中最重要的是防水层，它应兼有防水和阻止植物根穿透的功能。种植屋面常用的防水卷材主要包括改性沥青、PVC、OCB、TPO以及EPDM等。由于种植屋面荷载重、要求使用寿命长、不易维修等因素，国外采用叠层改性沥青防水层较多，但是，沥青基防水卷材阻根性较差，需要采取阻根剂、铝箔、铜蒸气等手段解决这一问题。PVC、OCB、TPO以及EPDM防水卷材只要具有较大的厚度，也可用于种植屋面单层铺设，或者铺在有沥青卷材作为下层防水的上面，组成多层防水。 Planting roof generally including planting, drainage and filtration layer, separating layer, waterproof resistance root, moisturizing, steam blocking layer, and at the grass-roots level, the most important of these is the waterproof layer, it should be both waterproof and prevent the function of plant root penetration. The main waterproof rolling materials used in planting roof include modified asphalt, PVC, OCB, TPO and EPDM. Because of planting roof load, requires the use of long life, not easy maintenance etc., using laminated modified asphalt waterproof layer is more abroad, however, poor root resistance of asphalt waterproofing materials, need to take root and corrosion inhibitor, aluminum foil, copper vapor and other means to solve this problem. PVC, OCB, TPO and EPDM waterproofing materials as long as have a larger thickness, also can be used in planting roofing monolayer laid, or on the asphalt coil as the top of the lower waterproof, composed of multi-layer waterproof. 种植屋面用卷材的阻根性能，是一个重要指标，但是，真正起到阻根作用的不仅仅是卷材本身，还有一个重要的环节就是卷材的搭接缝部分。 Planting roof with the coil resistance performance, is an important index, but the real is not only a coil itself, with the function of root resistance is another important aspect of lap seam part of the coil. 植物的根系生长，有一个向下的力，如果向下碰到阻力，那么，植物的根系就会向四周平行伸展。实际证明，阻根失败，有植物根系直接穿透卷材的，也有通过搭接缝穿过卷材的，所以说，卷材的搭接缝部分牢固与否，也直接关系到阻根成功与否。PVC、OCB和TPO防水卷材，由于它们是热风焊接，搭接缝与卷材形成一个整体，阻根性能就比较可靠。防水卷材虽然具有阻根性及耐腐烂等特点，但是如果接缝采用的粘结材料不合适，也很难保证阻根性能。 The root growth of the plant has a downward force, and if the resistance is encountered downward, the root of the plant will be stretched out in parallel. Show the actual resistance root failure, is plant roots directly through the coil, also have through lap seam through the coil, so to speak, lap seam part of the coil is firm or not, is directly related to drag a success. PVC, OCB and TPO waterproof rolling materials, because they are hot wind welding, the joint seam and the coil forming a whole, the resistance root performance is more reliable. Although the waterproof rolling materials have the characteristics of resistance and rot, it is difficult to guarantee the resistance to the resistance if the bonding materials are not suitable. 但是，任何卷材要作为种植屋面防水阻根材料使用，都必须通过有关实验室的测试，检测合格的才能采用。 However, any of the materials to be used as the root material for planting roofing waterproofing resister must pass the test of the relevant laboratory, and the qualified can be used. 在欧洲不采用刚性防水耐根穿刺，因为刚性防水虽然有很好的耐根穿刺效果，但刚性防水层没有延伸性，不能保证整体不出现开裂。 In Europe, rigid waterproof and resistant root puncture is not adopted, because the rigid waterproof layer has very good resistance to root puncture, but the rigid waterproof layer has no extension and can not guarantee the whole not to crack. 2、冷屋面高反射屋面 The cold roof reflects the roof 近年来，节能、环保，高反射冷屋面技术已经引起了广泛的注意，在2007年的美国屋面工程协会办的屋面工程展上可以发现，冷屋面涂料遍地开花，许多企业推出了冷屋面涂料，喷涂于传统屋面的外表，大部分是白色或浅色，降低屋面对阳光红外部分热量的吸收，降低屋面温度，达到节能的目的。 In recent years, energy saving, environmental protection, high reflection cold roof technology has caused wide attention, in 2007, the American association for the roofing construction of roof engineering show can be found that cold roof coating blossom everywhere, many enterprises launched cold roof coating, spray painting traditional roofing appearance, mostly white or light color, reduce the roof to sunlight part of heat infrared absorption, drop roofing temperature, achieve the goal of energy saving. 美国政府实验室的现场实验表明，一些新的冷屋面可以为住宅业主提供明显的节能效益，夏天冷负荷最高可降低20%。 Laboratory experiments in the us government have shown that some new cold roofing can provide significant energy saving benefits for residential owners, with a maximum cooling load of 20 per cent in summer. 实际上，节能只是冷屋面技术优点的一个方面，还可节省屋面的维护费用和延长屋面的使用寿命。 In fact, energy saving is only one aspect of the technical advantages of cold roofing. It can also save the maintenance cost of roof and prolong the service life of roof. 冷屋面通常是浅颜色的，对于平屋面或低坡屋面的商业建筑来说是可以接受的，但是对于住宅业主来说，他们喜欢的陡坡屋面是深色调的。 Cool roof is usually a light color, for commercial building to the roof or low slope roof is acceptable, but for home owners, they like to struggle up the steep slope of the roof is brunet attune. 目前，制造商已经开发出用于屋面材料的深色染料，不同的是这种颜料不是吸收而是反射太阳光，现已用于金属屋面涂料、粘土瓦、混凝土瓦和各种色调的沥青瓦的矿物粒料中，最近，公司利用3M公司开发出的深色矿物粒料推出了具有反射功能的沥青瓦，蓝灰色，反射率可达25%。 At present, manufacturers have developed the dark dye for roofing materials, the difference is this kind of paint is not absorbed but reflect sunlight, is now used for coating of metal roofing, clay tile, concrete, tile and all kinds of color of mineral aggregate of asphalt shingle, recently, the use of 3 m company developed dark mineral aggregate introduced with functions of reflection of asphalt shingle, blue gray, the reflectivity of 25%. 3M的反射彩砂对比试验证明，在高温照射下，普通砂的背面温度65.5℃，反射砂的背面温度58.3℃，降低温度7.2℃。 3 m reflective sand texture contrast test has been proved that under the irradiation of high temperature, the back of the ordinary sand temperature 65.5 ℃, reflection on the back of sand temperature 58.3 ℃, reduce the temperature of 7.2 ℃. 3、改性沥青防水卷材在欧洲的应用趋势 3. Application trend of modified asphalt waterproof rolling materials in Europe 在欧洲玻纤胎基主要用于保护层和氧化沥青卷材，SBS和APP改性沥青卷材99%采用聚醋胎。欧洲通常采用双层防水，氧化沥青玻纤胎卷材用于基层，表面采用聚醋胎改性沥青卷材，发展趋势是SBS卷材比例越来越大，APP逐渐减少。在欧洲，最上层暴露的改性沥青卷材的表面，一定是片岩或者是颗粒矿物粒料，主要就是为了抵抗紫外侵袭，提高卷材的耐老化能力，延长卷材的使用寿命。 In Europe, the fiberglass matrix is mainly used for protection layer and oxidized asphalt rolling materials, and 99% of the modified asphalt materials of SBS and APP are used to get polyacetous ones. Europe usually adopts double layer waterproof, oxidized bituminous fiberglass tire coil for the base level, and the surface is used to modify the asphalt rolling materials. The development trend is that the proportion of SBS is larger and larger, and the APP gradually decreases. In Europe, the top exposed on the surface of the modified asphalt coiled material and must be schist or mineral aggregate particles, mainly is to resist uv, improve the ageing resistance ability of coil, prolong the service life of coiled material. 4、太阳能屋面 Solar roofing 在欧洲，尤其在德国，政府和老百姓的环保意识都非常强。家庭很少用空调，规模不大的宾馆也都不使用空调，当地环境气候是一个原因。由于对环保的重视，近年来德国太阳能屋面应用越来越多。为了保护环境，使用绿色能源，德国的老百姓只要有条件，就在自家建造太阳能屋面，发电自用。德国政府也非常支持民间太阳能发电，对民间太阳能发的电，可以并人国家电网，用电按规定交纳电费，多余的电国家以双倍的价格收购。 In Europe, especially in Germany, the government and people are very environmentally conscious. The family rarely USES air conditioning, and the small hotels do not use air conditioning. The local climate is one reason. Due to the importance of environmental protection, more and more solar roof applications have been applied in Germany in recent years. In order to protect the environment and use green energy, the German people will build solar roofs and generate electricity from their homes as soon as possible. Folk solar power, the German government is very supportive of folk solar electricity, can and state grid, power in accordance with the provisions, pay the electricity bills, excess electricity state takeover at double the price. 德国最近计划出台新的可再生能源法，以促进可再生能源的发展，提高其利用比例。使德国2030 年50%的能源消费来自风能、水能和太阳能等可再生能源。 Germany has recently proposed new renewable energy laws to boost renewable energy and increase its use. By 2030, 50% of Germany's energy consumption will come from renewable sources such as wind, water and solar. 六、结语： Vi. Conclusion: 国际上目前产品开发和应用的主体是围绕世界性问题，比如节约能源、环境保护、节约资源、节省劳力、施工简便、安全高效等为新产品发展的方向。比如，太阳能屋面在德国的启动、TPO卷材的高速增长、自粘卷材的多样化发展、冷屋面系统的兴起、屋面垫层的重量轻和防滑要求变化等等，充分体现了这些理念。其中一个重要因素就是政府的重视和支持。 International product development and application of the main body is currently around the world, such as energy saving, environmental protection, resource saving, labor saving, construction convenient, safe and effective for new product development direction. Solar roof started in Germany, TPO, for example, rapid growth of the coil, the coil of diversified development, the rise of the cold roofing system, roofing mat layer of light weight and anti-slip requirements change, etc., fully embodies the concept. One important factor is the importance and support of the government. 欧美的防水材料产品和防水施工技术，确实要比我国的现有水平要高。但是，关键的还是欧美企业员工的敬业精神和对工作的认真态度。虽然目前国际上的防水材料产品品种我国基本上都有了，产品标准和施工规程规范我国也基本上都有了，但是，好的材料是不是都认真地按照规定去施工了，是不是都按照规定选材了，这是最关键的。 The waterproof material product and waterproof construction technology in Europe and America are indeed higher than the current level of our country. However, the key is the employee's dedication and serious attitude towards work. Although the current international waterproof material products basically have in China, the product standard and construction procedure specification also basically had in our country, but the good material is seriously to construction according to the regulation, whether all materials in accordance with the relevant provisions, it is the key. 从国外的防水设计和防水工法，以及系列产品的开发，都能充分体现国外人严谨、周到、认真、负责的工作态度和工作作风。对照我国目前的行业情况，与国际相比，还是有较大的差距，值得我们深思。 From abroad waterproof design and waterproof work method, and the development of series product, can fully reflect foreign person rigorous, considerate, serious, responsible work attitude and work style. Compared with the current industry situation in China, there is still a large gap compared with international, which deserves our deep thinking. |
