In actual application, building waterproofing membranes will come into contact with some exposed steel bar heads and other sharp objects on the foundation ground. If the nail rod tearing test of the building waterproofing membrane fails, it will cause sharp objects such as steel bar heads to easily pierce the membrane, causing the membrane to rupture and leak, and lose its waterproofing effect.
