Roof waterproofing is crucial in construction projects because it directly affects the durability and service life of the building. Effective roof waterproofing can prevent rain and moisture from penetrating into the building, avoid structural corrosion, mold growth and damage to the indoor environment, protect building materials, ensure the safety and comfort of the living or working environment, and thus reduce maintenance costs and repair costs. Therefore, roof waterproofing is a key link in ensuring building quality and living environment.
