三東興業 List of Products and Services

Our company temporarily borrows neighboring private land (such as rice fields, farms, and fallow land) and riverbanks near the Kamisato factory to extract gravel resources buried underground, which are then used as aggregates for concrete products, as well as to produce and sell fine sand for spreading on golf course fairways. We also manufacture natural sand (fine sand) that has been sifted using fine mesh from gravel resources extracted from rivers and other sources. We can also provide larger items such as cobblestones. Please feel free to contact us if you have any requests. 【Features】 ■ High-quality aggregates selected from natural raw stones mainly sourced from the Kanagawa River system ■ Retail options available *For more details, please download the PDF or feel free to contact us.
