Filter Sand and Gravel

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.
Precision sizing and uniform grading to close limits meet the rigid specifications of professional engineers throughout the word.

Filter Sand is graded specifically for water filtration applications. It can be used in residential, municipal or industrial applications for sediment filtrations.
Our 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.

Advantages:

  • Filter sand is graded specifically for water filtration applications
  • The spherical shape of uncrushed gravel promotes good flow and even distribution
