RIVER SAND
RIVER SAND
Sand is a granular material composed of finely divided mineral particles. Sand has various compositions but is defined by its grain size. Sand grains are smaller than gravel and coarser than silt. Sand can also refer to a textural class of soil or soil type; i.e., a soil containing more than 85 percent sand-sized particles by mass.
Rocks erode or weather over a long period of time, mainly by water and wind, and their sediments are transported downstream. These sediments continue to break apart into smaller pieces until they become fine grains of sand. The type of rock the sediment originated from and the intensity of the environment give different compositions of sand.
Sand's many uses require a significant dredging industry, raising environmental concerns over fish depletion, landslides, and flooding.[22] Countries such as China, Indonesia, Malaysia, and Cambodia ban sand exports, citing these issues as a major factor
RIVER GRAVER
RIVER GRAVER
River gravel is a name given to gravel composed of small pieces of rounded stone of various colors, usually no larger than a large coin.It is named for the effect of many years of rounding of the edges of the stones due to a flow of water over it, as often takes place in a river. River gravel is often used in outdoor settings, such as a park walkway.
River gravel is also occasionally used for landscaping purposes and placed by landscape architects in non-traffic areas of high visibility. It may be used with many plants and shrubs because the rounded surfaces ensure rain and other water will soak through to reach the roots for necessary nurture.

RIVER CHIPS
RIVER CHIPS
River rock chip stones are popular in landscaping and decorative projects. They are smooth and rounded, and come in a range of colors, such as brown, grey, and black. River rock chip stones are ideal for creating paths, borders, and water features, and can be used to add a natural and rustic look to outdoor spaces.
Stone chips are the basic components used for macadam road construction, concrete production, asphalt concrete, railroad track ballast, vase filler, aquarium, & home decor.
