產品特點
1、物理性：具有優異的物理力學性能，可抵御結構變形對防水層的影響；
2、可靠性：采用預鋪反粘法施工，高分子熱熔壓敏膠與結構層形成滿粘接，避免竄水影響；
3、穩定性：耐化學腐蝕、耐霉菌生長，可抵御復雜環境對防水層的影響；
4、環保性：接縫采用冷粘法施工，安全環保；
5、經濟性：可優化防水系統構造，節約隔離層、防水保護層及相應土方開挖外運費用。
1. Physical property: the product has excellent performance of physical and mechanical properties, which can resist to shrinkage deformation and cracking of the substratum.
2. Reliability: pre-applied installation before concrete pouring method can form fully and continuous bonding with construction substratum to avoid water flowing between interlayers.
3. Stability: it has excellent resistant performance of chemical and mould corrosion, which can withstand to influence of complex environment.
4. Environmental conservation: it is applied by self-adhesive construction method which is efficiency and environment-friendly.
5. Economic efficiency: the product application can optimize construction layers system, which can save the isolation layer, concrete protective cover, and reduce soil excavation and outward transport cost.
