Sand and gravel products lay the groundwork for virtually all construction, landscaping, and transportation applications. Specialty sand and gravel products are also responsible for the production of silica (for glass and many other uses) and for products such as filter sands. These aggregates are used in the production of road base, concrete, your favorite golf coarse, and even your car windows.

Sand and gravel deposits found on beaches or in rivers and streams, are mostly quartz (silicon dioxide, SiO2) grains. Weathering of rocks such as granite forms these quartz grains. In the process of weathering, the softer, weaker minerals in granite (such as feldspar) are weathered away. The more resistant quartz eventually is ground down in size, but does not break down chemically. In time
