Understanding the Different Types of Gravel

Here at Flesherton Concrete Products, one of the products we offer is high-quality gravel. If you’re not involved in the industry, then it may surprise you to learn that there are different types of gravel, each with different applications. Our team wants to help you choose the best supplies for your project, so in this article, we’ll be providing a brief guide to help you understand some of the different types of gravel used in construction.

The term gravel refers to rock fragments that have been rounded and worn by water. The distinctions between the various types of gravel typically involve the size of these fragments, as well as what other materials have been added to the mix. In our experience here at Flesherton Concrete Products, the most common gravel varieties you’ll hear about are A gravel, B gravel, and pea gravel. Also called granular A and B gravel, the first two types differ from pea gravel in that they have additional materials added to the rock, whereas pea gravel contains no such additives. Where A and B gravel differ from each other is that the fragments in B gravel must pass through a 150 mm (just under 6 inches) sieve to earn that label, while A gravel has to pass through a sieve that’s just 26.5 mm (a single inch) in diameter, meaning that the rocks are much smaller. Granular A and B gravel are frequently used for projects such as driveways and parking lots. Pea gravel is made from stones about the size of a pea (where it gets its name) and is extremely durable making it particularly suited to landscaping and other backyard uses such as patios and flower gardens.
