How to Choose Between 10mm and 20mm Shingle

When it comes to choosing the right shingle size for your project, it’s important to have a clear understanding of your options. We’re here to guide you through the decision-making process, whether you’re using shingle for decorative purposes, drainage, or any other application.

10mm Shingle

10mm Shingle, also known as ‘Pea Shingle,’ serves multiple purposes and offers versatility in various applications:

  1. Mixing: The small aggregate size with a large surface area makes 10mm shingle an excellent choice for blending with other materials, such as fine concrete.
  2. Drainage, Soakaways, and Pipe Laying: The compact size of 10mm shingle is perfect for drainage, effectively filling small gaps and optimizing the available space.
  3. Decorative: If you’re looking to enhance your garden’s aesthetics, suppress weeds, retain moisture, and protect against frost, 10mm shingle is a visually appealing choice for garden borders.


20mm Shingle

For specific applications like driveways and larger-scale projects, 20mm shingle offers a range of benefits:

  1. Driveways: The larger particle size of 20mm shingle minimizes the risk of it becoming stuck in tires or shoes. This ensures that the shingle stays where it’s meant to, making it an excellent choice for driveways, and it’s also gentler on your pet’s paws.
  2. Easy to Spread: When you need to cover a large area and want to conceal irregularities in the terrain, 20mm shingle is a practical choice. It spreads easily and levels out mounds and valleys effectively.
  3. Drainage, Soakaways, and Pipe Laying: When dealing with substantial drainage applications or supporting heavy pipes and soakaways, our 20mm shingle is the solution you need. Its larger particle size creates an aerated layer, allowing a significant volume of water to fill voids before reaching saturation.


Your choice between 10mm and 20mm shingle should depend on the specific requirements of your project. Whether it’s for decoration, drainage, or other purposes, understanding the distinctive characteristics of each shingle size will help you make an informed decision that suits your needs.
