Waterproofing is mostly used in roofs, underground buildings, underground parts of buildings, inner rooms and water storage structures that need waterproofing.
According to the different measures and means adopted, it can be divided into two categories: material waterproofing and structural waterproofing.
Material waterproofing is to block the passage of water with building materials, so as to achieve the purpose of waterproofing or increase the ability to resist leakage, such as coiled material waterproofing, coating waterproofing, rigid waterproofing of concrete and cement mortar, clay and lime soil waterproofing, etc.
Structural waterproofing is to take appropriate structural forms to block the passage of water, so as to achieve the purpose of waterproofing, such as water stop, cavity structure and so on.
The main application fields include roof, underground, external wall and indoor of building construction; Municipal projects such as urban roads, bridges and underground spaces; Bridges and tunnels of expressways and high-speed railways; Traffic engineering such as underground railway; Water conservancy projects such as water diversion channels, reservoirs, dams, hydropower stations and water treatment, and so on.
With the progress of society and the development of building technology, the application of building waterproof materials will be extended to more fields.
