However, for tireless waterproof membranes, if they meet the requirements of GB55030-2022 "General Specification for Waterproofing of Buildings and Municipal Engineering", double-layer construction is required. As we all know, labor costs are relatively expensive at this stage, and if the two layers of waterproof membranes cannot be fully adhered during double-layer construction, there is a greater risk of water leakage.

This puts higher requirements on construction, and it is difficult to improve construction quality and efficiency. Utility Model Content
