  31. To partially repair a roof leak, after removing the covering layer around the leak, I found that the water accumulated in the foamed cement was flowing down into the recess where the cover was removed.

  32. If there is partial leakage in the roof during renovation of the roof, but the pipes are complex and the thick waterproof and thermal insulation layer is up to 10 centimeters deep; if all the pipes are removed, the project will be very large and the waste generated will be difficult to remove; is it possible to use the back-to-back leakage prevention method and directly install the ceiling on the top floor?<\/a><\/li>\n\n\n\n
  33. The roof has water seepage at the tile fixing area. If the tile fixing is removed for partial renovation, it would take a lot of time and labor. Is it possible to use a simpler pouring method to achieve the effect of permanently stopping the leakage?<\/a><\/li>\n\n\n\n
