Do you need to prepare anything before the construction of roofing membrane waterproofing?
Before the construction of the roofing project, the construction unit should organize technical management personnel to review the roofing project drawings, master the construction drawings of the detailed structure and the relevant technical requirements and the actual situation of the project to prepare the construction plan or technical measures of the roofing project. This avoids leaving defects after construction, resulting in rework, while the project is planned according to the construction organization to prevent work omissions, mistakes, reversals affect the quality of the project.
With the construction organization, the next step of construction should be responsible for the technical delivery to the team. Content includes: construction parts, construction sequence, construction process, construction level, nodes set up methods, enhance parts and practices, engineering quality standards, technical measures to ensure quality, finished product protection measures and safety precautions.
Waterproofing of roofing projects must be waterproofing professional team or waterproofing construction, is strictly prohibited without the qualification level certificate of the unit and non-waterproofing professional team or non-waterproofing workers for waterproofing construction of roofing projects, construction units or supervisory companies should carefully check the induction certificate of construction personnel. Construction units should be construction processes, levels of quality self-inspection, self-inspection, self-correction and good construction records, supervision units do a good job of acceptance of each step of the process, acceptance before the next process, level of operation.
Waterproofing materials used in roofing projects should have material quality certification documents, and certification by the designated quality testing department to ensure that its quality meets the requirements of the relevant standards. Waterproofing materials into the construction site should be accompanied by factory inspection reports and factory certificate, and indicate the date of production, batch number, specifications, name. The construction unit shall be required to take samples for review, sample review in strict accordance with the witness sampling system, in the construction unit representative or supervisory unit personnel witnessed by the construction personnel in the field sampling, sent to the laboratory for testing. After passing the re-inspection, submit the re-inspection test report after passing the application in waterproofing projects. Prohibit the use of unqualified waterproofing materials in the project, unqualified materials should be found immediately all withdraw from the construction site.
1) high elasticity: the film elongation at break can reach more than 1000%, suitable for expansion joints and deformation joints, can effectively solve a variety of structures due to stress deformation, expansion cracking, puncture or poor connection and leakage, corrosion and other problems; effective treatment of structural deformation, to ensure that the waterproof effect.
Spray quick-setting rubber asphalt waterproofing coating consists of rubber asphalt emulsion A component and emulsion-breaking agent B component. A component consists of high solids emulsified asphalt and polymer. It will be co-blended modified to form a water-soluble mixture of polymer and emulsified asphalt. component A and component B is sprayed from the two nozzles of the special spraying equipment on site, atomized mix quickly after breaking the emulsion dehydration (within 10 s), coagulation into a film. After efforts, a dense, continuous and complete rubber asphalt coating is formed with high elongation, strong elasticity, excellent durability and waterproof, anti-corrosion, impermeability and protection. A spraying can reach more than 2 mm thickness, fast construction speed, environmental protection.
PVC waterproofing membrane is an excellent green waterproofing materials, with abundant raw materials, renewable use, harmless to human body and the environment and other advantages. Therefore, in the country's "fourteenth five-year plan" proposed "double carbon" goal, the country vigorously advocate emission reduction, PVC waterproofing roll-roofing has been the key promotion products in the field of polymer roll-roofing, in the building waterproofing industry occupies an important position.
PVC is the abbreviation of polyvinyl chloride waterproofing roll-roofing material, is a new type of polymer waterproofing roll-roofing material made of polyvinyl chloride resin and additives such as anti-oxidants and anti-UV. Ltd. production of PVC waterproofing membrane with high tensile strength, high elongation, shrinkage rate is small, low temperature flexibility, long service life, the product performance is stable, convenient construction.
Silicone waterproofing agent construction is generally divided into grass-roots surface cleaning, crack repair, spraying construction three procedures.
