Problems solved by technology

[0002] Three-felt four-oil and waterproof membrane are currently widely used building waterproof materials, but the construction of three-felt four-oil is complicated, and it causes serious pollution to the environment and high cost. Although there are many types of membranes, they are limited to covering waterproofing. For some complex parts or corner parts, it is not easy to construct, and it is not resistant to aging and has poor permeability
