What is the traditional waterproof method?

What new roofing waterproof materials are there? Roof leakage is a common problem in life and the most troublesome thing. How to prevent roof leakage is also one of the most concerned topics. Of course, roof waterproofing is inseparable from roof waterproofing materials, so what new roof waterproofing materials are there? At present, there are three popular new roofing waterproof materials, namely: CH- 108ZYY polymer cement waterproof coating, HG203 waterproof sealing coating and YYA special waterproof and impervious slurry. What new waterproof coatings are there for roofs? New waterproof coating for roof. CH- 108ZYY Polymer Cement Waterproof Coatings Firstly, the first new roof waterproof coating CH- 108ZYY Polymer Cement Waterproof Coatings is introduced. CH- 108ZYY polymer cement (also known as elastic cement) is a two-component waterproof coating based on acrylate synthetic polymer emulsion, with special cement, inorganic curing agent and various additives. It has good film-forming, impermeability and cohesiveness (compared with concrete, brick, stone, ceramic tile, ZYY plastic, color steel roof, airport roof, wood, glass, etc.). ZYY composite waterproof coating is divided into ZYY- 1 ZYY-2 models, of which ZYY- 1 model is mainly used for waterproofing of large deformation building parts. ZYY-2 is mainly used for building waterproofing in long-term immersion environment, such as basement, toilet and bathroom, swimming pool, reservoir, subway, tunnel, garbage disposal site and other projects. Product features: it can also be constructed in a very humid environment and solidified into a film; After the film is formed, it has the characteristics of molecular screening structure that is breathable and impermeable; After construction, cement mortar protective layer or ceramic tile decorative layer is directly made on the surface of waterproof coating, and the interface is firmly bonded.
