How It Works

Enter the width, length, and depth of the area you need to fill, then select your chosen aggregate type.

The calculator will work out the total volume in cubic metres (m³) and convert this into tonnes using standard industry density values for each material.

This calculator is intended as a guide only. Quantities are approximate and may vary depending on ground conditions, compaction, moisture content, and the specific material supplied.

We recommend allowing an additional 5–10% to ensure you have sufficient material for your project.
