Waterproof materials have long been a must in the modern construction industry. The quality of waterproof materials will directly affect the long-term use and quality of the entire building. Therefore, when choosing a waterproof material, it must be carefully selected and needs to be selected from various aspects. Quality assessment, but Xiao Bian suggested that you should first buy waterproof materials, it is best to first determine whether it is suitable for the use of the building, and then to its quality and environmental considerations, in the purchase of waterproof building materials need to pay attention to which process What about the details?
To buy suitable waterproof materials need to pay attention:
First of all, to select materials according to climatic conditions, such as southern rain, waterproof material should use water-resistant materials, such as modified bitumen membrane coil material or water-resistant adhesive adhesive polymer membrane; and the northern cold, especially many In selected regions, high-molecular-weight membranes that are resistant to low temperature, frost heave, and shrinkage should be used.
Secondly, the requirements for waterproof materials for different building parts are not the same, and they must be adjusted according to local conditions. Because of the construction of materials, waterproofing in roofs, walls, underground buildings and toilets can be described as very important in a building.
Since the roofing waterproof layer is exposed to the sun, rain, and rain, it is necessary to choose a waterproof material with high tensile strength, high elongation, and good aging resistance. The leakage of the wall is because the wall is now too thin, mostly light block masonry, a large number of internal and external joints, and then the joints between the doors and windows and the wall, the seal is not strict, rainwater seepage from the seam. Therefore, the wall can not be waterproof waterproof membrane, only with elastic waterproof coating, and the combination of exterior decoration materials.
The waterproof coating in the toilet room is most suitable. The first is because the toilet room is not affected by the natural climate and there is no temperature change, so the requirement for the elongation of the material is not high; the second is because the area is small, there are many yin and yang angles, and the floor pipe is worn. More, the paint can better adapt to the needs of the toilet room; the third is the tile on the waterproof layer of the wall, and the affinity with the adhesive is good, so the paint is the best choice for waterproofing between toilets.
The underground waterproof layer is immersed in water or in a very moist soil for a long time. The waterproof material must have good water resistance, the bottom waterproof layer should be thick, and there must be waterproof material with certain resistance to puncture. If synthetic polymer coils are used, it is best to heat weld joints. The use of adhesive joints, the glue should be excellent water resistance, otherwise no matter how good the coil can not be selected.
In short, in the process of choosing suitable waterproof building materials, we must choose according to the external environment of the building and the actual waterproof performance requirements. Only in this way can we purchase the excellent waterproof material suitable for the building!
