Traditional construction method of external wall waterproof plugging
If the building is leaking, it means that there is a problem with the treatment of the waterproof layer. There are hard ceramic tiles on the surface of the waterproof layer. The traditional method is to pry the outer tiles, dig out the waterproof layer, rebuild a new waterproof layer, and re-lay the tiles. . Among them, labor costs, material costs, and time spent are very large.
The latest method of external wall waterproof plugging
The traditional concept of waterproofing leaks is to patch up where the leaks are. The latest method of waterproofing leakage is to abandon this traditional concept. If the waterproof layer leaks, do a good job of waterproofing and leakproofing on the outside of the tile. As long as the surface of the tile is waterproofed, the waterproof effect is the same.
