Problems solved by technology

[0002] Waterproof membrane is mainly used in building walls, roofs, tunnels, highways, subways, landfills, etc., to resist external rainwater and groundwater leakage, a flexible building material product that can be rolled into rolls. There is no leakage connection between the engineering foundation and the building. It is the first barrier for the waterproofing of the entire project and plays a vital role in the entire project. According to its main waterproofing materials, it can be divided into asphalt waterproofing materials, polymer modified There are three types of asphalt waterproofing membranes and synthetic polymer waterproofing membranes. Therefore, the traditional asphalt waterproof material has short service life, poor chemical stability and unsatisfactory waterproof effect.
