1、物理性:具有优异的物理力学性能,可抵御结构变形对防水层的影响;
2、可靠性:采用预铺反粘法施工,高分子热熔压敏胶与结构层形成满粘接,避免窜水影响;
3、稳定性:耐化学腐蚀、耐霉菌生长,可抵御复杂环境对防水层的影响;
4、环保性:接缝采用冷粘法施工,安全环保;
5、经济性:可优化防水系统构造,节约隔离层、防水保护层及相应土方开挖外运费用。
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.
