If you’re undertaking any type of groundwork or construction, you’ll likely hear the term ‘aggregate’ a lot. There are different types of aggregates that all have their own unique advantages and uses, and you need to make sure you select the right one for your project. This isn’t easy, though, especially if you’re not familiar with aggregates or have ever used them.

To help you figure out which aggregate is best for your job, we’ve put together this simple guide detailing the main types and what they can be used for.


The Different Types Of Aggregates

There are several categories of aggregates, ranging from Type 1 MOT to sand. As mentioned, it’s imperative you choose the right aggregate so that you can complete your project to the highest standard. If you don’t, you risk the finish of your project, and depending on what’s being done, this could be catastrophic.

With this in mind, let’s explore the most common aggregates.



First, we have sand. There are different types of sand, so make sure you pay attention to the type you’re selecting. Generally speaking, sand is ideal for landscaping and gardens, brickwork, and agriculture. It’s also a useful aggregate for bolstering the strength of other materials like concrete.



Gravel is a good aggregate for drainage purposes, as well as creating aesthetically pleasing borders and focal points in a landscaping environment. Like sand, there are different types of gravel, so make sure you choose carefully because not all gravel looks or behaves the same.



Ballast is an exceptionally coarse type of aggregate that is used in concreting and similar applications due to its strength and stability. In fact, as well as being used in footings and foundations, it’s also sometimes used to provide stability for ships and cars!


Type 1 MOT

Type 1 MOT is a type of subbase that is commonly used to fill in areas ready for another layer on top, be it pavement or artificial lawn. Generally speaking, if you have a site to fill, Type 1 MOT is a good aggregate for the job. It’s made of a mixture of rocks and other hard, strong materials, though there are different types so make sure you take care when picking one.



If your work pertains to a garden or a landscape, topsoil is one of the best aggregates. It has a number of favourable factors that make it the ideal choice for those who take pride in their vegetation and plant life. Depending on your budget and your desired finish, you can choose from a range of topsoils, including standard, premium, enriched, and turfing soil.
