Distinctive feature
1. High water-stopping ability with this agent alone
In the case of collapsible ground, conventional polymer additives lacked sufficient water-stopping ability, requiring the use of bentonite in combination. On the other hand, Super Kadeizai has high water-stopping properties, allowing excavation to continue safely even when the soil type changes.
2. Reduction in usage, easy preparation of the solution, no dust generation
Super Kadeizai can reduce the usage of conventional polymer + bentonite by approximately 87%. Additionally, it significantly reduces the large-scale transportation of bentonite and the generation of dust.

How to use
- Add water to the mixer, gradually add the agent, and stir for 5 minutes (do not stir for more than 15 minutes).
- While excavating, inject the mixture into the chamber.
- Adjust the addition amount per 1m³ of water and the injection amount per 1m³ of natural ground based on the soil type and soil discharge conditions, using the table below as a guide.
