It is a flexible building material product that can resist leakage from external rainwater and groundwater. As a leak-free connection between the engineering foundation and the building, waterproof membrane plays a vital role in the entire project.

[0003] When overlapping the joints of waterproofing membranes, skilled workers are required to operate, especially EPDM waterproofing membranes, which have many joints. Poor joints will cause water leakage. At present, when splicing waterproofing membranes, it is necessary to fold the upper waterproofing membrane, brush industrial glue on the upper surface of the lower waterproofing membrane, and then adhere the upper waterproofing membrane and flatten it to drive out bubbles. When folding the waterproofing membrane, a tool is used to brush a thin layer of glue on the upper waterproofing membrane to temporarily fix the folded membrane. Since the membrane is usually long, it is necessary to dip and brush glue, which affects the convenience of laying the membrane.

The overlapping portions at two locations are arranged to facilitate determining the width of brushing glue. There is no need to measure the overlapping width with a tape measure, which can improve the overlapping efficiency.

[0026] The paving layer 107 is configured as a butyl rubber glue adhesive layer, and the thickness range of the paving layer 107 is configured to be 2±0.5 mm.
