This type of rubber dam has a cross-sectional profile resembling a book; the exterior of the dam body is entirely flat and smooth. It is integrally molded and vulcanized in a single process at the factory, a method that enhances the lateral tension of the dam bag while mitigating vibration and the impact of overflowing water.
The dam bag creates a beautiful visual spectacle during overflow, offering significant aesthetic appeal. Furthermore, the dam bag features a flat surface, and its spine-like structure enables it to collapse completely, forming a flat plane.
