    design.
- **Drainage Systems:** Excellent flow characteristics for effective subsurface drainage.
- **Railway Ballast:** Lightweight alternative for ballast layers, reducing track maintenance.
- **Pipe Bedding:** Provides stable and shock-absorbent support for pipelines.
- **Land Reclamation:** Improves soil aeration and drainage in challenging environments.
