Sand Gravel Sediment

1998-3-23 · ABOUT SAND. Sand, along with gravel, silt and clay are collectively known as sediment, and are produced by the mechanical and chemical breakdown of rocks.Once disaggregated from the original source rock, this material is then eroded and transported by either wind, water or ice, often ending up at the deposits of rivers or lakes, as sand dunes, or ultimately as sediment in the sea.

Whatever your requirements, you 'll find the perfect service-oriented solution to match your specific needs with our help.We are here for your questions anytime 24/7, welcome your consultation.
