As long as it is a national standard waterproof material, any enterprise and brand are similar. If used in the right place according to the instructions, it can be guaranteed for 5 years after construction.

The key to waterproof is the quality of the building. If it is constructed with national standard materials, water leakage can be avoided. Once the water leaks, it must be repaired every 3-5 years. It doesn't matter which material or brand you use, because you can't buy materials that really solve the problem completely in the market.

The country stipulates that the warranty period of waterproofing is five years, so what the market needs is materials with a five-year warranty and the lowest price. Only materials that meet this demand can sell well and enter the mass market, that is, materials that ordinary people can buy.

Is there any material that can solve the water leakage problem once and for all? The answer is yes, but it is expensive and belongs to minority consumption. You can't buy it in the market. What you can buy is a flicker, and you need to buy it through special channels.
