Q: Dr yao hello, after the construction of multiple outdoor waterproof engineering, I found the roof through wall pipe part leakage, over time I also groped out a set of governance scheme, just recently encountered a new problem, roof through floor pipe leakage, because the problem is different, I dare not rush to do, to consult

A: well, in fact, roof through floor pipe and wall pipe partial protection measures are basically the same, the cause of leakage is basically the same: in the weak link of external waterproof, especially spread waterproof roll, pipe root joint edge more, it is difficult to do all parts are full stick, once around the problem in the root, from pipe root and structure connection water seepage to the inside.

Q: Yes, the weak link of external waterproof has always been a big problem, it is difficult to solve completely, but since encountered such leakage problem, how also have to properly solve for customers, in order to achieve the purpose of long-term waterproof ah!

A: This kind of problem, if it is not impossible to choose traditional waterproof coil construction, but as I said before, there will still be the pipe root of the connection, and the technical requirements of the construction workers are particularly strict, do not pay attention to, the previous work will be wasted, repair and leakage

Q: Well, yes, then Dr. Yao. If you use modified asphalt rolling materials, how to put an end to such problems?

A: If this material must be selected, I suggest that the coil additional layer shall be at least 500mm, 250mm, plane joint width 250mm, with the original waterproof layer, the old waterproof layer is not less than 100mm, the elevation waterproof layer shall be not less than 200mm, and with the lower waterproof additional layer.

Q: Well, Dr. Yao, If you don't choose waterproof rolls, what is better?

A: I recommend you to choose the roof high elastic waterproof coating brush construction, more convenient and more lasting.

Q: Well, it is Jiagushi's AE-1000 high elastic polymer modified asphalt waterproof coating, can you detail the specific construction plan?

A: Well, The construction process is as follows: 1. Remove the surface layer and insulation layer outside 500mm to the structural surface, Clear the groove around the pipe (the size of the tank is 20 * 30mm); 2. Clean up the debris and dust in the tank, Then fill sealing paste in the tank; 3. Repair the base with plugging king or cement mortar to leveling; 4. Brush 500mm wide roof high elastic waterproof coating additional layer and line mesh cloth for enhanced treatment (250mm, Plar lap width is 250mm); 5. Restore the leveling layer of the roof structure level to the lower part of the original waterproof layer; 6. Brush the roof high elastic waterproof coating and lining the mesh cloth to form and match with the original waterproof layer, The lap width of the new and old waterproof layer shall be 100mm, The facade waterproof layer shall be 200mm above the surface layer and connected with the lower waterproof additional layer, The receiving part of the pipe root facade shall be sealed with sealing paste;, 7. To restore the protective layer and other related structures on the upper layer of the waterproof layer.

Q: Well, thank you, Dr. Yao.I still choose to use the roof high elastic waterproof coating, easier to operate and more at ease.

A: you're welcome.

Q: What material should be used for grouting the waterproof layer?

A: We can use our grouting immortal water, which is heat and aging, and can live the same life as the structure. It is not recommended to solidify with water, because the roof's long-term solidification of ultraviolet light is easy to cause water loss and shrink, and the life pipe is not long.

Q: Know, thank you, Dr. Yao. I'll immediately try your two plans to see which one is more economical and simple.

A: OK, not welcome.
