Throughout the United States and the rest of the world, there are many companies whose main purpose is to provide sand and gravel to businesses and homeowners in the local area. One or more quarries are the source of base material and the products are transported to a central location, such as the Riverside sand and gravel firm. An S&G firm is highly capital-intensive, since heavy equipment of various types is required to remove the raw material from the ground and load it into trucks or other vehicles. At the central facility, there is need for additional equipment to clean, size and store the product. Usually delivery trucks are necessary to get retail products to the consumers.
Sands are graded by color, size and purpose. The particles can range in color from white to dark. They can be coarse or as fine as sugar. Some labels which have been attached to various grades include "remix", "crushed limestone", "concrete", "white brick", "mason" and "cushion sand".
Gravel is categorized by size. It ranges from particle-sized to pebble-sized. A sand and gravel firm will often sort and store gravel by size of individual units. This is done by sizing screens which allow the individual units to drop into bins or areas depending upon the size of particles.
There are many uses for the rock particles. Many areas in the United States and the rest of the world as well use the small rocks as the coating for roadways. The surface may be periodically covered with a layer of small rock fragments, especially in rural areas. Grooming of road surfaces is a matter of running a road grader with a blade to move the fragments into a more even layer.
Another major use for rock particles, regardless of the size, is in the production of concrete. It is fairly common for S&G companies to also distribute concrete to contractors, homeowners and others. The wet concrete mix is carried to the customer's site where it is poured or shoveled into place and leveled.
S&G facilities are required to comply with state and local regulations in order to protect the neighbors. Some of the considerations include hours of operation, noise and traffic congestion caused by trucks. There may be requirements about the distance of the plant or quarry from neighbors. There may be restrictions about locating the plant near a recreational area.
The location of the quarries is an issue to humans who live nearby, but it can also affect the wildlife in the area. There may be limited hours of operation to reduce noise stress for birds and animals. Pollution of nearby water is another consideration.
Delivery of products is another part of the services provided by an S&G company. Rock particles are heavy. Even a single cubic yard can weigh 3K pounds. The customer might need three yards, five yards or even more, depending upon the size of the project.
