The mountain sand for golf courses, "White Sand," is refined from weathered granite containing a lot of granite from the mountains of Daskoshi in Iwakuni City at our own factory, and has been developed for use as topdressing sand and base sand for turf. "Mountain sand" does not contain salt like sea sand, and organic matter and fine soil are carefully washed away, making it suitable for use in vegetation. "Mountain sand 2mm" is currently being used at various golf courses in the prefecture as sand for golf course turf and bunker sand. Since it is produced in different grain sizes, the particle size distribution is uniform, and it does not put a load on turf machinery, thus not reducing work efficiency. Additionally, due to its moderate water retention, it is also suitable as topdressing sand for turf during the peak summer season. We offer a lineup of 4mm, 2mm, and 1mm to suit various usage purposes. It is used for turf sand in soccer and baseball fields, sandboxes and ground leveling in schools and parks, as well as for plastering sand, among other applications. 【Mountain Sand Product Lineup】 ■ Sand 4mm ■ Sand 2mm ■ Sand 1mm ■ Fine sand (10mm, 6mm) *For more details, please download the PDF or feel free to contact us.
