Roof waterproofing works generally include roofing coil waterproof, roofing film waterproof, roofing rigid waterproof, tile roofing waterproof, roof joint sealing waterproof. Roof waterproofing is strictly prohibited on rainy days, snowy days and high winds above grade five. The ambient temperature conditions for construction are compatible with the waterproof materials and construction methods used. Once the roof leakage rate was high, the housing function was seriously affected. The leakage problem of the roofed roofs has directly affected people's life, work and study.
In order to solve the problem of leakage of roofs in existing buildings, systematic management and comprehensive prevention and control should be carried out from the aspects of design, construction, materials, management and maintenance of waterproofing works. In order to improve the quality of waterproof projects and eliminate leakage, we should start with construction, strictly control the quality of materials, improve the design level and strengthen management, and take specific measures to carry out comprehensive prevention and control.
Roof waterproof construction should pay attention to the following matters:
1. material selection
In the treatment of roof leakage, we should vigorously promote the application of new waterproof materials. We should first select polymer modified bitumen coils and coatings, synthetic polymer membranes and coatings, elastic plastic sealing materials and new rigid waterproofing materials with advanced technology and excellent performance.
2. roof waterproof design
In the design, waterproofing should be carried out according to the nature of the building, engineering characteristics, importance and function. According to the local maximum and minimum temperature, daily temperature difference, roof slope, waterproof layer form (exposed or non exposed) and the size of the structure, select suitable waterproof material, and determine the corresponding construction plan.
3. construction is the key.
Construction of seepage control works must be carried out by trained professional waterproofing construction teams with professional training, familiar with construction specifications and waterproof material performance and applicable scope. In the construction process, we must strictly abide by the national standards and standards, conscientiously implement the process standards, meticulous and meticulous operation, so as to ensure the quality of the project.
4. strengthening management and maintenance
Regular roofing maintenance, such as taking full clearance of the waterproofing layer before the rainy season and before winter, and finding timely repair of damage, will be of great significance for reducing roof leakage rate, reducing rework, saving expenses and prolonging the service life of waterproof layer.
