Types of Aggregates Everyone Should Know

Aggregates have been a crucial element of construction for hundreds of years. 

From large-scale builds to domestic and DIY projects, aggregates are commonly used in almost any construction or landscaping project you can think of. They are commonly used to set up foundations and top decorative layers for various kinds of projects. No matter where you go, you will likely be surrounded by structures built using different types of aggregates.

However, how do you choose the right aggregate for your project? 

Fortunately, aggregates come in a variety of sizes and textures with many other characteristics that can help you decide what type of project they are best suited for. 

In this blog, we will examine some popular types of aggregates alongside their uses to help you make the right choice for your next project.

Let’s begin!

1) Sand

Sand is a widely used aggregate that is suitable for many different applications. As sand can vary in structure and colour there are various types of sand available, each with its own uses.  

Sharp sand or coarse sand can be used for slab laying, screeding, concrete, plastering and rendering. Building sand or Soft Sand can be used for mortar or lime mortar. Sand fill is an inexpensive material that is used for filling trenches, utilities and, depending on its stone content, for pipe and cable laying. Sand is also used in the production of glass.

With its incredible versatility, sand is a useful aggregate that provides strength and stability to all types of outdoor construction and landscaping projects.

2) Gravel

Gravel is a type of loose aggregate. It can be made from larger pieces of crushed or broken stone giving it an angular appearance. In comparison, natural gravel is made from stones that are weathered or eroded, so they are generally more rounded.

Gravel can come in many shapes and sizes from as small as 4mm to much larger stones of 200mm. This makes it suitable for many uses. Due to its sturdy nature, gravel is a building material that is used in areas of high traffic such as driveways, roads and pathways. 

Alongside sand, gravel also plays an important role in the production of concrete. The larger stones are also used for soakaways to fill gabion baskets. Gravel is a durable and versatile material well-suited for many types of projects. 

3) Crushed Stone

Crushed stone is stone that has been extracted, crushed into smaller fragments, graded and then used for various construction applications. 

Some common types of crushed stone include crushed gravel, MOT Type 1, granite and slate. 

From commercial builds to residential projects, crushed stone is a popular choice. Its high durability makes it ideal for long-term projects such as roads, driveways and building foundations.  

4) Sub-base

Sub-base aggregates can be primary or made of crushed stone or recycled materials and act as the foundation layer for various types of projects.

Sub-base aggregates form the base layer of many structures and help with even load distribution and drainage. 

By providing stability and support, sub-base aggregates prevent the settling or shifting of the upper layers of many structures, to preserve their structural integrity.

5) Topsoil

Topsoil is an aggregate consisting of the uppermost layer of the soil. When Topsoil aggregates are combined with fertiliser, they become an ideal material for plant growth.

6) Carrstone

Carrstone is a type of sandstone that is commonly used in construction. Its distinct rusty brown colour makes this aggregate a functional choice for projects.

Carrstone provides strength and a striking visual element. Its durability and porous nature make it especially useful in the construction of various structures. Carrstone Straights can be used for anything from deep fill to garden rockeries while Carrstone Fines for subbase, capping layers and driveways as they compact down so well.

Carrstone aggregates are used in large construction, landscaping and garden features to improve the functionality and appearance of outdoor spaces.
