How Much 40mm Limestone Do You Need?

Each bulk bag contains approximately one cubic yard of 40mm limestone. Enter your project length, width and desired stone depth below to estimate the number of bulk bags required.

40mm Limestone Coverage Guide

One cubic yard of limestone provides approximately the following coverage at different depths:

For practical ordering, allow approximately 100 sq. ft. per bulk bag at a 3-inch depth. As a larger decorative stone, 40mm limestone may require sufficient depth to achieve a consistent finished appearance.

Landscaping with 40mm Limestone Rock

40mm limestone is a popular option for landscaping projects where a larger decorative stone is desired. Its angular shape and natural grey colouring complement garden beds, retaining wall landscapes, patios and other outdoor features.

The larger rock size creates a bold finish, particularly in wider garden beds, rock gardens and landscape borders. It can also be used to create decorative contrast with smaller aggregates, mulch and planted areas.

For decorative ground cover, prepare and level the area before spreading the limestone evenly. Appropriate ground preparation or landscape fabric can help reduce soil mixing and simplify maintenance.

For engineered drainage, erosion control, driveways or structural base applications, confirm the required aggregate grading and specifications before installation. Decorative limestone is not automatically interchangeable with compactable road crush or engineered base material.

20mm vs. 40mm Limestone

Both 20mm and 40mm limestone are natural crushed stone products, but they create different decorative finishes.

20mm limestone offers a smaller, finer aggregate appearance and may be better suited to areas where a less prominent stone texture is desired. The larger 40mm limestone produces a more substantial rock appearance, making it an attractive choice for decorative garden beds, borders and landscape features.

Choose the size based on your preferred appearance, installation depth and intended application. For construction uses, the correct aggregate specification is more important than appearance alone.
