How to distinguish the roof waterproof grade
Roof waterproofing grades are mainly the ability of roofing waterproofing. In order to distinguish different grades, it is generally based on the construction process and the selected waterproof material. There are no specific requirements for the specific materials for waterproofing at all levels, as long as the waterproof capacity and the service life can be achieved. Then how should the roof waterproof grade be divided? The following Xiao Bian gave you a brief introduction.
Roof waterproof rating
1, the roof waterproof level 1
Application occasions: buildings that are particularly important or have special requirements for waterproofing;
Waterproof layer reasonable service life: 25 years;
Waterproof layer selection materials: synthetic polymer waterproof membrane, polymer modified asphalt waterproof membrane, metal sheet, synthetic polymer waterproof coating, fine stone concrete, etc.
Fortification requirements: three or more waterproof fortifications.
2, the roof waterproof level 2
Applications: important buildings and high-rise buildings;
Waterproof layer reasonable service life: 15 years;
Waterproof layer selection materials: Polymer modified bitumen waterproof membrane, synthetic polymer waterproof membrane, metal sheet, synthetic polymer waterproof coating, polymer modified asphalt waterproof coating, fine stone concrete, flat tile, linoleum Tiles and other materials;
Arming requirements: two waterproof fortification.
3, roof waterproof level 3
Application: General construction;
Waterproof layer reasonable service life: 10 years;
Waterproof layer selection material: three felt four oil bitumen waterproof membrane, polymer modified bitumen waterproof membrane, synthetic polymer waterproof membrane, metal plate, polymer modified asphalt waterproof coating, synthetic polymer waterproof coating , fine stone concrete, plain tile, linoleum and other materials;
Arming requirements: a waterproof fortification.
How to distinguish the roof waterproof grade
According to the division of waterproof and other energy, the reasonable service life of buildings is different, that is, the length of the repair cycle is different. Therefore, the level of protection for the waterproof layer is also different. Level I is three or more, Level II is two, and Level III is one. This fully reflects the difference in the number of years of service life, the long life cycle, and the use of more waterproof materials. At the same time, it is also related to the material used. For example, Grade III optional three felt and four oil waterproof, polymer modified asphalt paint, plain tile, and linoleum can not be used as a main waterproof layer in the Class I waterproof project.
The above is a brief introduction for Xiaobian. If you want to know more related information, please continue to pay attention to Qijia Consulting. More exciting consultation, please stay tuned.

With the constant improvement of the people environmental protection consciousness, not only requires metope paint, waterborne implementation also requires floor waterborne coating system gradually realize to reduce the negative effect on the environment, but the wear resistance of floor coating system is conventional water-based coating cannot be achieved. To thoroughly solve the technical problems, the company USES advanced technology research and development center, adopt special special water-based epoxy resin and Curing Agent, with special processing technology and the emulsification technology, has developed an excellent environmental performance, has high abrasive resistance and solvent resistance of the waterborne Epoxy Floor Coating System. Waterproof breathable function of the system greatly improves the system applicability of wet subgrade, is all not do the waterproof layer, damp, but at the same time, and have high cleanliness requirements, need to coating epoxy floor coating system places ideal choice.
