AI Technical Summary
Existing waterproof membranes are prone to problems such as loose joints, punctures, and damage during construction and use, leading to potential water leakage, and they also lack self-repair capabilities.
A water-swellable waterproof membrane was designed, comprising a protective layer, a waterproof layer, and a water-swellable layer. The water-swellable adhesive expands and fills gaps after contact with water. The adhesive is confined to a fixed area by the first and second water-soluble isolation layers and the arched portion to prevent leakage.
It achieves self-sealing overlap, no side leakage, and instant self-repair, improving the waterproof effect, enhancing the bond between the membrane and concrete, and preventing water seepage and puncture damage.
