1. Material preparation and technical quality requirements
① All the waterproof materials in the basement must be waterproof materials approved by the Civil Air Quality Supervision Department and issued with a permit.
② The waterproof materials used in underground waterproofing and toilet waterproofing projects must have a product quality certificate and performance inspection report that have passed the national quality inspection. The variety, specifications, and performance of the materials should meet the current national product standards and design requirements. Unqualified materials must not be used in the project.
③ The waterproof and heat-insulating materials used in roofing projects shall have a product qualification certificate and performance test report. The variety, specifications and performance of the materials shall meet the current national product standards and design requirements.
2.Retesting and quality control of waterproof materials

3. The impervious concrete used in the basement, floor and outdoor wall must be submitted to the material laboratory in advance, and a test report of the proportion must be made and submitted to the supervisor for approval.
4. Technical details and requirements for operating skilled workers
⑴ Before waterproof construction, technical, quality, and management personnel must first be familiar with the design requirements, and fully understand and understand the construction specifications, construction plans, and technical requirements. Knowing it well, the technical and quality acceptance standards are clear.
防水, waterproof engineering is a special control process, operating technical workers must have a special permit for waterproof work, undocumented personnel are not allowed to work.
(3) Before the waterproof construction, the person in charge of the construction technology of the project, the project engineer, must personally carry out the construction plan for the technical management personnel and the foreman, and the technical details must be provided.
