If you need to use sand or gravel in a project, you might not be sure exactly what kind you need. There are so many different names and appearances associated with both sand and gravel that you might just be overwhelmed. To help clear that up a bit, here's the rundown on some of the most common types of sand and gravel which are used in construction.
- Pit sand: a fairly course variety of sand that often is reddish-orange, and generally used in concretes
- River sand: a much finer sand than pit sand, river sand is whitish-grey and better suited for plastering
- Sea sand: a brownish sand which is poorly suited to construction projects. However, it is a good choice for decoration, as long as you are close enough to a coast that the cost of transportation remains low.
- Artificial sand: a variable type of sand created by man, which has a wide range of possible colors and coarseness. It can be expensive, due to the relative infancy of the technology used and the high cost associated with an artificial sand machine.
- Crushed concrete: an environmentally friendly option that uses recycled concrete which has been reduced to small chunks. It lacks visual appeal, but is cheap and a good choice for a base layer.
- Crushed asphalt: similar to crushed concrete, crushed asphalt is environmentally friendly, cheap, and a satisfying shade of black. It is a good option for a driveway because it's dust-free and won't erode in the rain.
- Limestone: a bright white option that is somewhat messy. Limestone gravel tends to be dusty and erodes when wet.
- Dolomite: another white option which can have hints of grey and blue. It is harder than limestone, but is similarly dusty.
- Slag: a grey rock that is created as a byproduct of steel. It is both porous and packs loosely, which means that it is a good choice for drainage.
- Road Gravel: a very common mottled type of gravel composed of brownish stone. Clay is generally abundant in road gravel, and thus it is very cheap. However, this comes at the cost of being both slick when wet and dusty when dry,
- Pea Gravel: small, round, multicolored rocks which can be used as decorative gravel. A fairly cheap option, pea gravel comes in a variety of shapes, sizes, and colors.
Regardless of what type of sand or gravel you are interested in, it can often be easier to contact a company like Floyd Preston Limited which specializes in stone delivery than to attempt to transport it yourself.
