Measures taken from building materials and structures to prevent water from penetrating into certain parts of the building. Waterproof is mostly used in roofs, underground buildings, underground parts of buildings, and interior rooms and water storage structures that need to be waterproofed.
The construction and application of building waterproof materials is the key to selecting the right waterproof materials
Different parts of the building should choose the corresponding waterproof material for construction. The waterproof material of the building is different according to the choice of different parts. Some parts are suitable for waterproofing membranes, and some parts are suitable for waterproof coatings. Waterproof requirements are also different. Each type of waterproof material has its own strengths and weaknesses. One material cannot cover the world. There is no material that is good for any place. Various materials can only complement each other and cannot be replaced. Each has its own abilities. Roofing and basement waterproofing require different material properties, and the waterproofing of the bathroom is more different from the waterproofing of the wall. Slope roofs, roofs with complex shapes, and metal sheet base roofs are also different, and material selection should be carefully considered.
1. The roof waterproof layer is exposed to nature, exposed to hot sunlight, strong winds, rain and snow erosion, severe cold and scorching temperature, and repeated expansion and contraction of the temperature difference between day and night, without good material properties and good protection Measures, it is difficult to achieve the required durability. Therefore, a waterproof material with high tensile strength, high elongation and good aging resistance should be selected.
2. The reason why the wall leaks is due to the fact that the wall is too thin, mostly made of light block masonry, with a large number of internal and external joints, and the joints between doors and windows and the wall are not tightly sealed, and rainwater seeps through the joints. Coiled materials cannot be used for wall waterproofing, only waterproof coatings, and combined with exterior decoration materials. Only sealing paste can solve the problem of window installation seams.
3. Waterproof materials for underground construction. The underground waterproof layer is immersed in water or very humid soil for many years. The waterproof material must have good water resistance.
4. There are three characteristics of the waterproof of the toilet and bathroom. First, it is not affected by natural climate, temperature changes are not there, and the elongation rate of the material is not high; the second is small area, many yin and yang corners, and more pipes through the floor; third, the tile is attached to the waterproof layer of the wall for bonding Good agent affinity. According to the above three characteristics, coiled materials cannot be used, only waterproof coatings are most suitable.
