Gravel

Gravel consists of small rocks that are used as aggregate in concrete or paving. This material is also used to create a structural base for a roadway, or to aid in soil drainage. Different types of gravel are also placed around planting beds to serve as decoration and as a form of weed control. A gravel pit that provides this type of small stone will generally not include any type of slabs, or larger stones. Some gravel pits, however, may naturally include metals or minerals that can be mined along with the gravel.
