The roof is exposed for a long time, directly corroded by sunlight, snow and rain, and the temperature changes greatly in severe winter and hot summer.

① Roofing: The roof is exposed for a long time, directly corroded by sunlight, snow and rain, and the temperature changes greatly in severe winter and hot summer. The roof panel will expand and contract during day and night. Therefore, materials with good aging resistance, certain extensibility and high heat resistance should be selected. . Such as mineral grain, polyester tire modified asphalt coil, EPDM sheet or asphalt felt. To
② Underground: According to the long-term damp condition and difficult maintenance of underground engineering, but the temperature difference is small, a combination of rigid and flexible multiple fortifications should be used. In addition to rigid waterproof additives, it should also be used with good mold and corrosion resistance. Long-life flexible materials. When waterproofing the cushion, puncture-resistant materials should also be used, such as glass fiber with a thickness of 3mm or 4mm, polyester tire modified asphalt coil, glass cloth linoleum, etc.; when using high For molecular waterproofing substrates, adhesives with good water resistance must be used, and the thickness of the substrates should not be less than 1.5mm; when using waterproof coatings, materials that form fast and do not produce re-emulsification, such as polyurethane and silicone rubber waterproof coatings Etc., its thickness should not be less than 2.5mm. To
③ Toilet and bath room: Generally, the area of the toilet and bath room is small, there are many yin and yang angles, and there are many kinds of floor-piercing pipes, and the construction of coils and sheets is difficult. Waterproof coatings should be used. The coating can form an overall seamless film. Affected by the uneven shape of the base surface, such as JS composite waterproof coating, neoprene latex asphalt coating, polyurethane waterproof coating, etc. For pipes that pass through the floor, sealing paste or water-swelling rubber strips can be used.
