How to use building waterproof materials correctly and reasonably

As long as there is a place for construction projects there must be waterproof materials,
waterproof coatings
more kinds, according to different waterproof
coatings
performance used in the building is also exquisite, today for you to briefly describe how to correctly and reasonably use building waterproof materials?
the correct choice and rational use of building waterproof materials
waterproof materials due to variety and performance, so each has different advantages and disadvantages. Also have the corresponding scope of application and requirements, especially the promotion and use of new waterproof materials, but also should master this side of the knowledge. The correct selection and rational use of building waterproof materials, is the key to improve the quality of waterproofing, but also the premise of design and construction, for this reason should pay attention to the following points:
1. the performance and characteristics of materials
building waterproof materials can be divided into flexible and rigid two categories. Flexible waterproof material stretch strength, large elongation, small quality, convenient construction, but the operating technology requirements are more stringent, puncture resistance and anti-aging performance is not as good as rigid materials . The same flexible materials, coils for factory production. Thick and uniform, relatively stable quality, simple construction process, high efficiency, but more equipment, seams easy to disloddy, complex surface and uneven grass-roots construction is difficult. The performance and characteristics of waterproof coatings are the opposite of theirs. The same is the coil, synthetic polymer coil, polymer modified asphalt coil and asphalt coil also have different advantages and disadvantages. It can be seen that when selecting waterproof materials, we must pay attention to their properties and characteristics.
2. Building functions and external environmental requirements
After understanding the performance and characteristics of various types of waterproof materials, should also be based on the structure type of the building, waterproof construction form and the outside climate of the node site (including temperature, humidity, acid rain, ultraviolet light, etc.), the structure of the building (whole or assembled) and span, roof slope, ground deformation and waterproof layer exposure and other materials to determine the appropriate.
. Construction conditions and market prices
the selection of waterproof materials, should also take into account the construction conditions and market price factors. For example, synthetic polymer waterproof coils can be divided into elastomers, plastic bodies and reinforced synthetic fibers three categories, not only different materials, but also greatly different performance; At the same time, consideration should also be given to the actual use of the selected materials locally; Construction conditions such as binders and construction processes that are matched with synthetic polymer waterproof coils should also be taken into account. The above waterproof coils as an example put forward the requirements of material selection, the same waterproof coatings, sealing materials also have many varieties, but also a variety of technical indicators, but the requirements of material selection and the above-mentioned basic same. In addition to the above points, the selection material should further consider whether the waterproof layer can adapt to the deformation of the grass roots.
