Problems solved by technology

[0002] The traditional organic waterproof membrane is slowly withdrawing from the stage of history due to its fatal weakness-short lifespan, which cannot last the same life as the building
The organic waterproofing membrane itself is expensive, coupled with refurbishment every 5 or 10 years, it will not only damage the environmental protection, but also greatly increase the cost
[0003] At present, organic waterproofing membranes are expensive, and have poor corrosion resistance and short lifespan. Good economic and social benefits
