6.
The supervision of waterproof construction process shall be carried out in the whole process station.
After drying, it is pasted with SBS, with a range of ¢ 330.
8.
Raw material mobilization inspection and witness sampling retest report 2.
The bonding firmness, overlapping length and bonding fullness shall be checked at the overlapping part.
This part is prone to quality problems, so a special scheme shall be made before construction.
Structural self waterproofing is an important guarantee for base plate waterproofing.
3、 Record control 1.
The material brand, carcass, thickness and model shall meet the requirements of the contract and specifications.
Concrete, post cast strip pouring and water stop steel plate shall be implemented in strict accordance with the specifications.
The length of the new and old waterproof joints between the base plate waterproof and the exterior wall facade waterproof shall not be less than 150mm.
After paving, the coiled material shall be flat and straight, and the overlapping size shall be correct without distortion.
The waterproof unit and the general contractor must hand over the working face and form a written handover record.
After completion, it shall be reported to the quality supervision station for special acceptance.
Working face handover form, supervision on-site record and concealed acceptance record 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.
2、 Control standards and precautions 1.
5.
The materials shall be sampled and submitted for inspection after mobilization, and can be used only after passing the inspection; 2.
