Different construction sites have different requirements for waterproof materials, and the construction methods are also different. Waterproof membrane manufacturers understand that each material has its own advantages and disadvantages. One material cannot cover the whole world, and no material can be used everywhere. Various materials can only complement each other, but they are irreplaceable. Each has its own characteristics. per location.
Roof waterproofing and basement waterproofing have different material requirements, and the difference between bathroom waterproofing and wall waterproofing is even greater. There is also a difference between a pitched roof and a roof with a complex shape, so it is important to be careful about the materials. Let's learn more from Hubei waterproofing membrane manufacturers: The roofing waterproof layer is exposed to nature and has withstood the repeated tests of scorching sun, strong winds, sleet erosion, severe cold and heat, and temperature difference between day and night. Without excellent materials and good protection measures, it is difficult to achieve the required durability due to thermal expansion and cold contraction. Therefore, waterproof materials with high tensile strength, large elongation and good aging resistance should be selected.
Such as polyester tire polymer modified asphalt membrane, EPDM rubber coil, P-type PVC coil (welded joint), one-component polyurethane coating (with protective layer). Why does the waterproof wall leak on the wall?The reason is that some walls are now too thin, mostly lightweight blocks, with a large number of internal and external joints, and the joints between doors and windows and walls are not tightly sealed, allowing rainwater to penetrate through the joints.
The wall waterproof tank and tank are made of membrane material, and only paint is used, which is combined with the exterior wall decoration material. Only sealants can solve the problem of joints where the window frame is installed. The waterproofing layer of underground buildings is soaked in water or very moist soil for many years, and the waterproofing material must have good water resistance. The membrane made of perishable carcass cannot be used, and the base waterproof layer should be made of thick waterproof material with certain puncture resistance. The recommended stack thickness is 6mm 8mm. If a synthetic polymer film is used, the joint should be thermally welded. If the seam is sealed with glue, the glue must have excellent water resistance, otherwise even the best film will not work. Use caution when using waterproof paints.
The main thickness is 2 when used alone5mm, the thickness of the coil composite is 2mm thick. Bathroom waterproofingThere are three main features of bathroom waterproofing. First, it is not affected by the natural climate, the temperature change is small, and the elongation of the material is not high. Second, the area is small, there are many yin and yang corners, and there are many pipes passing through the building. Thirdly, the tile is attached to the waterproof layer of the wall, which has a good affinity with the adhesive. Based on the above three characteristics, we can choose the coil. Only the coating is suitable. Cementitious acrylic paints in the paint are suitable for sticking tiles firmly to them.
In the process of waterproof urban construction of overpasses, more and more reinforced concrete beams and slabs in overpass projects must be waterproofed to prolong their service life. Since the waterproofing layer is paved with high-temperature asphalt concrete pavement, the waterproofing layer must be able to withstand the high temperature of 110°C. Choose self-whitening asphalt coating or modified asphalt membrane.
