How is the waterproof grade divided Introduction to the selection of waterproof materials

Roof waterproofing grade, mainly the ability of roof waterproofing, to distinguish the grades, generally according to the construction process and the selection of waterproof materials.

There are no clear requirements for the specific materials of waterproofing at all levels, as long as the waterproof capacity and service life are reached.

The specific requirements for the waterproof level of the roof are shown below

1. Roof waterproof grade 1:

Applications: Buildings of special importance or with special requirements for waterproofing;

Reasonable service life of waterproof layer: 25 years;

Materials for waterproof layer: synthetic polymer waterproofing membrane, polymer modified asphalt waterproofing membrane, metal plate, synthetic polymer waterproof coating, fine stone concrete and other materials should be selected;

Fortification requirements: three or more waterproof fortifications.

2. Roof waterproof grade 2:

Applications: Important buildings and high-rise buildings;

Reasonable service life of waterproof layer: 15 years;

Materials for waterproof layer: polymer modified asphalt waterproofing membrane, synthetic polymer waterproofing membrane, metal plate, synthetic polymer waterproof coating, polymer modified asphalt waterproof coating, fine stone concrete, flat tile, linoleum tile and other materials should be selected;

Fortification requirements: two waterproof fortifications.

3. Roof waterproof grade 3:

Applications: General construction;

Reasonable service life of waterproof layer: 10 years;

Materials for waterproof layer: it is advisable to choose three felt and four oil asphalt waterproofing membranes, polymer modified asphalt waterproofing membranes, synthetic polymer waterproofing membranes, metal plates, polymer modified asphalt waterproofing coatings, synthetic polymer waterproof coatings, fine stone concrete, flat tiles, linoleum tiles and other materials;

Fortification requirements: a waterproof fortification.

Do it according to the normal basement waterproofing specification!

1. The level of waterproof protection function, including building waterproof grade, instrument waterproof and dustproof grade, is mainly determined according to the nature, importance, functional requirements, building structure characteristics and durability of the waterproof layer.

2. The following situations are comprehensively considered when dividing the waterproof level: after leakage, it will cause huge losses, until the person's **; Leakage can cause significant economic losses; After leakage, it will cause general economic losses; After leakage, it will affect the appearance.

3. The waterproof grade of the building should be determined by the designer according to the nature, importance, and functional requirements of the building when designing the waterproof, and then the waterproof material should be selected according to the waterproof grade and the durability of the waterproof layer.

Waterproof grade division: waterproof grade of roofing engineering, grade: three or more waterproof fortifications, reasonable service life of waterproof layer 25 years.

Grade: two waterproof fortifications, the reasonable service life of the waterproof layer is 15 years. Level:

A waterproof fortification, the reasonable service life of the waterproof layer is 10 years. The waterproof grade includes the waterproof grade of the building and the waterproof and dustproof grade of the instrumentation. It is mainly determined according to the nature of the building, its importance, the functional requirements for use, the characteristics of the building structure and the durability of the waterproof layer.

What are the precautions for waterproof construction:

1. The quality of waterproof materials is the key.

There are a wide range of waterproof products on the market in China, in addition to the general-purpose and soft type, there are also familiar JS, K11, GS and other products. Although these products are good, you must choose the best products when purchasing, so as not to affect the quality of the project.

2. The waterproof foundation should be properly disposed of.

When carrying out waterproof construction, we must do a good job of foundation treatment, especially in places where the water consumption is relatively large and humid, and the waterproof layer must be high and complete, so that there will be no leakage and other problems.

3. The waterproof layer should be protected after decoration.

After the waterproofing is done, it is necessary to do a good job of protecting the finished product to prevent man-made damage, such as: personnel must wear slippers when entering and exiting, do not pile up sundries on the site, and do not block the shooting.
