Gravel
Gravel, also known as shingle, is a loose building material made of rock fragments, mostly rounded and varied in size. It is widely used in the construction industry for laying foundations, roofing works, driveways, and roads. Gravel can also be mixed with sand to create concrete for road construction. To lay gravel on the soil you need to make preparations, such as deciding on the type of gravel, and calculating how much gravel you need.
