5. Leakage problem
So far, leakage is serious in our country, and it is urgent to enhance the quantity of waterproofing.
The keys to solve problem are reasonable design, careful construct and in-time protection.
What’s more, usually the tenet of waterproof uses rigidity and soft waterproof and defends on different coats.
Waterproof material is developed in the directions of higher properties, multifunction with lower pollution.
