Chengdu factory waterproofing and leak repair company informs business owners that factory leaks can be a severe issue. To prevent factory leaks, it's crucial to select the right waterproof coating. The base layer for waterproofing and leak repair must ensure that the interface with the waterproof materials is free of blisters, sanding, honeycomb structures, wood, paper shreds, mud, small stones, and should not be applied on loose and unstable surfaces.
Firstly, before waterproofing and leak repair in the factory building, it's necessary to identify the leak points and the causes of the leaks. Factory leaks may be due to improper use of waterproofing materials, poor workmanship by the construction crew, or environmental and other natural factors.
Generally, look for leaks from high to low, checking if there are cracks in the factory building's roof; if the waterproofing layer on the roof has aged significantly and lost its waterproofing effectiveness; and if there are blisters in the waterproof membrane. Blisters in the waterproof membrane indicate water has渗入the roof's waterproofing layer, which means the leak issue is quite severe. Additionally, inspect if the roof gutters of the factory building are blocked.

The key is to add a reinforcing layer between the new and old waterproofing layers.

Apply two coats of water-based waterproof paint or transparent waterproof material, ensuring the band width is over 20cm even if only sealing the gaps. This ensures strong adhesion. Waterproof coatings are all penetration bonded, have good elongation, and thus have a long service life.
