7.
After completion, it shall be reported to the quality supervision station for special acceptance.
2、 Control standards and precautions 1.
(long press the QR code identifying the picture below to buy) ——————-.
Structural self waterproofing is an important guarantee for wall waterproofing.
The facade waterproof and base course must be fully bonded without hollowing.
3、 Record control 1.
The waterproof unit and the general contractor must hand over the working face and form a written handover record.
At the lap joint of new and old coiled materials, the original coiled material interface shall be cleaned, and the lap joint can be carried out only after being accepted by the supervisor.
4.
The bonding firmness, overlapping length and bonding fullness shall be checked at the overlapping part.
The supervision of waterproof construction process shall be carried out in the whole process station.
The material brand, carcass, thickness and model shall meet the requirements of the contract and specifications.
5.
Concrete, post cast strip pouring and water stop steel plate shall be implemented in strict accordance with the specifications.
After the completion of vertical wall concrete, the joint with the bottom plate shall be uncovered, and each layer shall be cleaned.
The course covers the leakage detection technology of “tap water pipe, hot water pipe, drainage pipe (sewer), smoke exhaust pipe, air conditioning pipe and wire pipe” – from the basic knowledge of indoor pipe type, material, pressure resistance and pipe fitting connection, to the standard leakage detection process, equipment purchase suggestions, pressure suppression technology, and then to the leakage detector, thermal imaging, endoscope, fluorescence detection method The use technology of water leakage detection instruments and tools such as plugging tester, as well as a large number of experience in dealing with difficult problems on the water leakage detection site, are summarized in this tutorial· The course includes: “8 video courses + 1 paper book + more than 100 course supporting video materials”· In addition to video and paper books, we also provide 6-month technical guidance services.
If there is any damage, it shall be repaired, and the overlapping length shall not be less than 150mm.
The materials shall be sampled and submitted for inspection after mobilization, and can be used only after passing the inspection; In order to ensure full adhesion of facade, cold primer oil shall be sampled on site for compatibility test.
After paving, the coiled material shall be flat and straight, and the overlapping size shall be correct without distortion.
3.
Raw material mobilization inspection and witness sampling retest report 2.
Working face handover list, on-site records and concealed acceptance records today, I recommend a book to masters who really want to learn waterproof technology: the second edition of indoor water pipe leakage detection technology, which starts from scratch in a real sense, Systematically learn the tutorial of indoor water pipe leakage detection technology.

6.
If the basement is not subject to structural acceptance, it shall be reported to the quality supervision station for acceptance of the perceived quality of wall concrete before waterproof construction.
