Reserve Silica Corporation is a reliable supplier of quality tan bunker sand, free of contaminants, and meeting the requirements of our unique customer base.

Reserve Silica Corporation owns 402 acres of land where it operates an open pit sand mine and processing plant near Ravensdale, Washington, about 30 miles southeast of Seattle. The operation has existed since the early 1970's. Our sand comes from a deposit laid down over 50 million years ago. It is mined by open pit methods and then transported approximately one mile to our processing plant.

The plant manufactures a special tan bunker sand for the golf course industry, and as a component in the manufacture of concrete block. The sand goes through several processes that include crushing, washing, and screening. The Tan Bunker Sand is specially designed for use in golf course bunkers (both greenside and fairway bunkers). This sand is also used by the block industry for its unique color and sizing.

The plant operates on a campaign basis and has a large stockpile of finished product and two large stockpiles of ore.

Reserve Silica also operates a clean fill dumpsite with two below grade pits. The operation can efficently handle large numbers of customers. More information is available on our dump site information page.
