There are two different types of gravel which are 10mm and 20mm. 10mm gravel, also known as ‘pea gravel’ is primarily used for decorative purposes and drainage but it’s a versatile product as it can be used in a number of ways such as in mixing. As a small aggregate with a large surface area, 10mm gravel is an ideal aggregate for use in/with other materials such as fine concrete.
It’s also used in drainage, soakaways and pipelaying, as its ideal for drainage as it fills small gaps and makes the most of the area. In terms of aesthetic gravel is pleasing on the eye and will brighten up most gardens – helping to suppress weeds, retain moisture and protect plants against frost.
In general, we suggest that 20mm gravel is best suited for driveways but it also has its other advantages. In terms of driveways, the larger particle size means that it’s much less likely to get stuck in tyres or shoes. This means that it doesn’t get transferred to unwanted areas and stays in place for a longer period of time. It can also be considered pet-friendly as its much kinder on pets paws. 20mm gravel is also much easier to spread across a large area and hide mounds well.
In terms of drainage and pipe laying, 20mm gravel is great for large drainage applications where you need to support a heavy pipe – the larger particle size creates an aerated layer, which allows a large volume of water to fill these voids before saturation.
Crushed concrete is an aggregate composed of clean crushed concrete and brick. The size of this aggregate varies from 75mm down to 40mm.
Sharp sand is typically made from ground rocks and is sometimes referred to as builders sand as its ideal for laying blocks, paving and patios.
Ballast refers to a mixture of sand and gravel that is used to make concrete. Generally, the size of the grains/stones vary from 0.1mm upwards to 20mm.

Topsoil is defined by the top 2-7 inches of soil that has the greatest organic content. Organic matter is what is left after plant roots and leaves.
Building Sand is a finer grade than sharp sand with smaller particles. It’s often mixed with water and cement to make mortar for laying bricks, patio slabs and blocks.
MOT Type 1 is a sub base that is formed using recycled crushed concrete and consists of rubble of varying size. It compacts well to form a solid base which makes it an ideal sub-base.
This sand is used to fill the joints of block paving and paving slabs. By filling the joints with paving sand you keep the structure of the paving rigid and strong.
