Today, I recommend a book for masters who really want to learn waterproof technology: the second edition of indoor water pipe leakage detection technology, which is a real tutorial to systematically learn indoor water pipe leakage detection technology from scratch.
500mm wide double-sided self-adhesive coiled material shall be set at the junction, turning point and internal and external corners of the plane and facade of the additional layer of self-adhesive coiled material, and the plane and facade shall be spread evenly; 5.
Scope of application: Construction of single-sided self-adhesive waterproof coiled material waterproof layer of basement roof.
There shall be no hollowing, cracking and sand returning on the plastered surface of the vertical wall, and the installed water and electricity pipes, flue and other casings must be completed; The plane and facade joints, turning points, internal and external corners, etc.
The construction of protective layer shall be carried out four days after the completion of waterproof construction.
4.
The thickness of self-adhesive coiled material for large surface construction is 3mm, the polyester tire is self-adhesive on one side, and the wet bonding method is adopted for construction, which is required to be fully bonded with the base course; The overlapping length shall not be less than 80mm, and the coiled material at the overlapping part shall be double-sided self-adhesive.

The junction of self-adhesive coiled material and SBS coiled material of side wall must be turned over to the vertical wall for 200mm, and the self-adhesive coiled material and SBS coiled material of vertical wall shall be connected by hot melting method.
The upper opening of the coiled material turned over to the wall must be completely put into the flood tank and fixed firmly.
The base course shall be cleaned by base course treatment, and the base course shall be flat, clean and dry.
Process flow: base course treatment → additional layer of self-adhesive coiled material → large surface construction of self-adhesive coiled material → construction of protective layer.

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.
3.
shall be made into uniform, flat and smooth rounded corners, and the arc radius shall not be less than 50mm; Deal with defective parts and construction joints of concrete; Where it is necessary to close the mouth on the vertical wall, a flood tank shall be reserved; The joint with the side wall elevation coiled material must be cleaned.
The facade of the protective layer adopts perforated brick masonry 120 wall as the protective layer; The plane adopts 50 ~ 70mm thick fine aggregate concrete to slope to the blind ditch.
