This is gravel produced from the Hayatsuki River in Namerikawa City, Toyama Prefecture. It is granite with low salt content and good permeability (drainage). Due to the absence of alkali-silica reaction, it does not experience deterioration phenomena such as rusting or cracking when used in cement. The gravel particle size is 5 to 10 mm. It can be used in a wide range of concrete applications, including retail store facilities, public transportation for schools, roads, and sports fields. Shipping costs vary depending on location, method, and quantity, so please consult us first. *For more details, please refer to the PDF document or feel free to contact us.*
