Red Flint Filter Gravel are naturally- occurring, river-washed, glacial deposit products. Their excellent chemical properties - high in silica content and low in soluble calcium, manganese and iron compound - meet AWWA-B100-89 specifications. Precision sizing and uniform grading to close limits meet the rigid spec­i­fi­ca­tions of professional engineers throughout the United States, Canada and overseas.

For over 50 years, Red Flint River sand and gravel have been satisfying the requirements of industrial and municipal users. Red Flint products have been specified and used nationally and internationally because of their high-quality, desirable chemical properties, color and a wide range of precision sizing.

Processing and regular analysis are supervised by registered professional engineers. Pre-shipment analysis is available to be certain of compliance with specifications.

FILTER SAND is graded specifically for use at water filtration plants. It can be used in municipal, industrial or residential ap­pli­ca­tions.

The highly spherical shape of UNCRUSHED GRAVEL promotes good flow and even distribution. Being low in soluble impurities, it will maintain the quality of the treated water, especially in softeners. Three inch layers are recommended in graded support beds.

Our filtration silica sand and gravel offer extremely high pure silica content (>99% SiO2). All gravels are washed, dried and sized using PLC controls for consistency. All gravel verieties meet American Water Works Association B100 Specifications for Granular Filter Media and are NSF certified for Standard 61 – Drinking Water System Components & Materials.
