The testing device for production of building waterproofing membranes reads the difference between the distances before and after stretching through a laser transmitter and a laser receiver, and then obtains the anti-stretching effect of the building waterproofing membrane. At the same time, water can be sprayed to the top of the building waterproofing membrane through a water inlet pipe and an atomizing nozzle, and its waterproofing effect can be obtained by observing whether the anhydrous copper sulfate plate changes color, thereby realizing the simultaneous detection of its stretching and waterproofing.
