Waterproofing membrane


performance

  The new waterproof material has strong impermeability, high resistance to high and low temperatures, as well as good strength and elongation. It is easy to operate, fast, and easy to master. It is widely used for roof waterproofing of high-end buildings, underground engineering waterproofing, tunnel top waterproofing, and leakage in garbage dumps.


scope of application

  Roads, railways, airports, water conservancy projects, environmental protection projects, electric power projects, waterproof materials, ground leather substrates, etc.
