Our Filter Sand and Gravel are naturally occurring, river washed, glacial deposited products. Their excellent chemical properties are high in silica content and low in soluble calcium, magnesium and iron compounds. Filter Sand is graded specifically for water filtration applications. It can be used in residential, municipal or industrial applications for sediment filtrations.
