Elastomer bituminous waterproofing membrane code should pay attention to several points when going to the manufacturer for inspection, equipment technical status, raw materials (asphalt model, whether there is SBS, tire base cloth), and the laboratory. When choosing materials, consult the salespersons of several manufacturers in person to verify. Don't trust the samples they provide you too much, so you can take the samples they provide to the warehouse of his unit to check whether they are consistent. The selection of materials should be convenient for construction, and the unreasonable proportion of bad coiled materials will lead to problems such as slow construction and many hidden dangers.
The bonding area of the roof waterproofing polymer waterproofing membrane is required to be more than 85%, and the underground waterproofing area is required to be more than 90%, and the bonding layer must be continuous. Using polyurethane glue for lap joints, do not apply cement glue to the lap joints of polymer waterproofing membranes when laying polymer waterproofing membranes, so as not to affect the bonding of the joints. After the polymer waterproof membrane is laid, hard particles and impurities are not allowed in the lower part of the polymer waterproof membrane to avoid damage to the composite membrane.

Elastomer bitumen waterproof coiled material code construction preparation work: the preparation work before the construction of the underground engineering coiled material waterproof layer, the supporting materials, machinery and paving methods and precautions required for the construction are the same as the roofing engineering coiled material waterproof construction. When the groundwater level is high, drainage work should be done to reduce the groundwater level to not less than 30mm below the low elevation of the bottom of the membrane waterproof layer to facilitate the drying of the base layer and the solidification of the adhesive. After the construction is completed, it is still necessary to continue to drain for more than 7 days to allow sufficient curing time for the adhesive.
After the surface of the coil is melted, roll the coil forward immediately, and compact and flatten the coil. The stubble part should be pressed out of molten asphalt. Do not involve air and foreign objects during rolling, and prevent deflection and lift. Drums and creases. Then use a blowtorch and presser to seal the seams evenly and carefully to prevent edge warping. Quality inspection and requirements. The various technical performance indicators of the modified bitumen waterproofing membrane selected should meet the requirements of GB18242-2000, and the product should be accompanied by a quality inspection report for on-site sampling for review and verification or other relevant material quality certification documents. Then ignite the torch to aim at the bottom surface of the coil and the surface of the base layer and heat uniformly at the same time (the nozzle of the torch is about 30cm away from the surface of the coil).
The influence of the roof usage process. In normal use, the asphalt linoleum waterproofing membrane is damaged due to roof repair or other equipment installed on the roof. When the Master’s roof is overhauled, the asphalt felt can easily be stepped on without paying attention to protection. When other equipment is installed on the roof, ordinary waterproofing membranes may be damaged for fixing. The roof is the outer maintenance structure covering the upper layer of the building. Its main function is to protect human production and life from natural dangers. The flexible waterproof material forms a film through a chemical reaction to isolate the building structure from the environmental water and achieve the purpose of waterproofing. Rigid waterproof material improves the impermeability of the concrete base by increasing the density and reducing the porosity. Whether flexible waterproof materials and rigid waterproof materials are good or bad depends on whether the decoration environment is flexible or rigid. The ductility of the flexible waterproof material adapts to slight structural deformation, and is more suitable for the decoration of new and old houses.

The concealed pipe of the upper water pipe is not installed properly, the water pipe is inferior, and the galvanized pipe is rusty and aging, which may cause water leakage. If the water leakage is caused by the rust and aging of the galvanized pipe, the galvanized pipe can only be installed in the leaking place, and the galvanized pipe is easy to be corroded, so it is better to replace all the galvanized pipes. The waterproof layer of the light-body wall in the shower area is not up to meters high, and the light-body wall is easily damp in the damp environment all year round. For the health and safety of the home, it is recommended to knock off the wall tiles and re-waterproof it.
