[0002] Waterproof membrane is mainly used for building walls, roofs, tunnels, roads, landfills, etc. It is a flexible building material product that can be rolled into a roll to resist the seepage of external rainwater and groundwater. As a leak-free connection between the project foundation and the building, it is the first barrier to waterproofing the entire project and plays a vital role in the entire project.

[0003] Among them, synthetic polymer waterproofing membrane is a composite sheet waterproofing material that is made of synthetic polymer materials as the main raw material and is compounded with synthetic fibers to form two or more layers of rollable composite sheet waterproofing materials.

When making the joints, it is necessary to ensure that the pasting area is flat, dry, clean, and free of oil, dust and other debris. If dust and oil are mixed into the joints, it will inevitably affect the waterproof performance of the joint gaps and leakage will easily occur.

In order to protect the joints from dust absorption, a film is usually applied to the self-adhesive edges or hot melt adhesives for protection. However, when the protective film is removed, the pasting area will still absorb dust, resulting in gaps when the joints are pasted, thereby affecting the waterproof quality of the construction project.
