After the completion of waterproofing, the general contractor shall immediately organize the construction of waterproof protective layer.
After the construction of self-adhesive coiled material, all parts must be fully adhered without hollowing.
At the lap joint of new and old coiled materials, the original coiled material interface shall be cleaned and bonded after being accepted by the supervisor.
The materials shall be sampled and submitted for inspection after mobilization, and can be used only after passing the inspection.
Raw material mobilization inspection and witness sampling retest report 2.
After completion, it shall be reported to the quality supervision station for special acceptance.
Concrete, post cast strip pouring and water stop steel plate shall be implemented in strict accordance with the specifications.
The concrete surface of the basement roof must be calendered as a waterproof base.
The bonding firmness, overlapping length and bonding fullness shall be checked at the overlapping part.
3.
If there is crack water leakage, the crack must be treated before waterproof construction.
The supervision of waterproof construction process shall be carried out in the whole process station.
If it does not meet the requirements, 1:3 cement mortar shall be used for repair and leveling.
2、 Control standards and precautions 1.
(long press the QR code identifying the picture below to buy) ——————-.
The material brand, carcass, thickness and model shall meet the requirements of the contract and specifications.
The post cast strip in the basement can be reserved first, and then the waterproof connection can be made after the post cast strip is closed.
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.
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.
The waterproof unit and the general contractor must hand over the working face.
3、 Record control 1.
During the construction of self-adhesive coiled material, the base surface must be dry, otherwise the coiled material will not be firmly bonded to the base course.
Before waterproof construction, the floating soil and laitance on the concrete roof must be cleaned, and then the surface shall be washed with a water gun, and then the basement roof shall be observed from the basement.
After the waterproof construction is completed and accepted, the working face shall be returned to the general contractor.

2.
If it is found that the base course is not cleaned, uneven, laitance and cracks do not meet the waterproof construction conditions, it shall not be handed over and must be handled by the general contractor.
If the site conditions permit, the waterproof construction shall be started one week after the completion of the basement roof concrete; If the site conditions do not permit, waterproof must be done in the later stage.
The coiled material shall be flat and straight after paving, and the overlapping size shall be correct without distortion.
Structural self waterproofing is an important guarantee for wall waterproofing.
