Non-asphalt-based reactive pre-packaged polymer self-adhesive film waterproofing membrane

Non-asphalt-based reactive pre-packaged polymer self-adhesive film waterproofing membrane is specially developed for underground and tunnel engineering. It can be pre-laid with post-cast concrete structure to form a strong anti-bonding waterproof membrane. The coil is a polymer self-adhesive waterproofing material in which a resin-based polymer (EVA, LDPE, HDPF, ECB, etc.) is used as a main waterproof material, and a polymer waterproof substrate is coated with a self-adhesive film. The self-adhesive layer of the coil self-adhesive layer and the anti-environmental protection layer have self-healing function. After reacting with the liquid concrete slurry, the gap between the waterproof layer and the concrete structure is formed, and the hidden danger between the layers is eliminated, which can effectively improve the waterproof system. reliability.
