Use Our Aggregate Calculator to Order Just the Right Amount

Calculating the required amount of gravel for your project is a straightforward process. Begin by measuring the length, width, and depth of the area you intend to cover with gravel. Make sure to use consistent units of measurement, such as feet or meters. Next, multiply these dimensions to calculate the volume of gravel needed, typically in cubic units, like cubic feet or cubic meters. For a more convenient and precise calculation, you can utilise an aggregate calculator like the one provided by Castleton Turf. This tool allows you to input your measurements and instantly receive accurate quantities of gravel, ensuring your project planning is both efficient and reliable.

The coverage of 1 tonne of gravel largely depends on the thickness of the gravel layer you intend to spread. On average, a tonne of gravel can cover an area of about 10 to 12 square meters (approximately 108 to 129 square feet) when applied at a depth of around 2.5 centimetres (1 inch). However, if you’re aiming for a different thickness or working with varying types of gravel, it’s advisable to use an aggregate calculator to determine the precise coverage for your specific project. This ensures that you have the right amount of gravel to complete your landscaping or construction task effectively.

Underneath your gravel, it’s often recommended to lay a layer of landscaping fabric or a geotextile membrane. This barrier serves several purposes, including preventing weed growth by blocking sunlight and hindering weed roots from penetrating the surface. It also helps maintain the gravel’s stability by keeping it separate from the underlying soil. Additionally, a well-placed membrane helps with drainage, allowing rainwater to pass through while reducing the risk of soil erosion. When planning your project, consider using the appropriate underlay material to create a stable, weed-free, and aesthetically pleasing gravel surface.
