| Sodium hypochlorite(20ppm) | Normal |
| Seawater | Normal |
| Machine oil | Normal |
Method
All the materials were soaked into each solution for six months after being set up on the slate plate by the B-1 method, and any swelling, cracks, peeling, and holes were subsequently examined.

Pressurized Permeability
| system | The permeability of each material was visually observed |
|---|---|
| A-1 | No permeability |
| B-1 | No permeability |
| No processing | Water penetrated and leaked after pressurized for 5 minutes. |
Method
In accordance with JIS A1404, 491 kPa water pressure was put on the material for one hour and any water leak was observed.
