Fine Sand and Gravel

Flowmatic Fine Sand and Gravel are naturally occurring, river washed, glacial deposit products. Their excellent chemical properties - high silica content and low soluble calcium, magnesium and iron compounds. Precision sizing and uniform grading to close limits meet the rigid specifications of professional engineers throughout the world.
Flowmatic Fine Sand is graded specifically for water filtration plants. It can be used in municipal, industrial or residential applications for sediment filtration.
Flowmatic Gravel has a highly spherical shape that promotes good flow and even distribution in support beds. Gravel is low in soluble impurities and it will maintain the quality of the treated water, especially in softeners. Three inch layers are recommended in graded support beds.
