50mm–90mm Rundle Rock Coverage Guide

One cubic yard of large Rundle Rock provides approximately the following mathematical coverage:

Because individual stones can be approximately 3.5 inches across, a 3-inch layer may leave visible gaps and an uneven finished surface. Approximately 4–6 inches may provide a fuller decorative appearance, depending on stone distribution and project conditions. Coverage figures are mathematical estimates.

Landscaping with Large Black Rundle Rock

Large Rundle Rock is ideal for landscape projects where the individual stones are intended to create visual impact.

The dark charcoal colour pairs well with natural stone retaining walls, light-coloured paving stones, timber features and ornamental plants.

Its angular shape and layered texture create a rugged appearance that works particularly well in natural rock gardens, decorative borders and feature beds.

Compared with smaller decorative gravel, 50mm–90mm Rundle Rock creates a more substantial, coarse-textured finish.

How to Install 50mm–90mm Rundle Rock

1. Remove weeds, debris and unwanted vegetation from the installation area.
2. Prepare and level the underlying surface to establish the desired finished grade.
3. Install suitable landscape edging or containment where required.
4. Determine whether landscape fabric is appropriate for the installation.
5. Calculate the required volume using the project area and intended depth.
6. Spread and position the larger stones to achieve the desired decorative appearance.
7. Check for uneven areas or exposed ground and adjust the stone distribution as needed.

Large angular rock can be difficult to walk on and may require additional handling during installation. Use appropriate footwear and equipment. Avoid piling stone directly against tree trunks or plant crowns.

50mm–90mm Rundle Rock vs. Smaller Rundle Rock

Rundle Rock is available in different decorative sizes to suit a variety of landscape applications.

Smaller Rundle Rock is often more practical for narrow borders and projects requiring a finer decorative finish.

The 50mm–90mm size is better suited to larger landscape beds, rock gardens and decorative features where the individual stones should remain prominent.

For customers seeking a bold, coarse-textured black landscape stone, 50mm–90mm Rundle Rock provides a distinctive alternative to smaller decorative aggregates.
