40mm Washed Round Rock Coverage Guide

One cubic yard of washed round rock provides approximately the following coverage at different depths:

Rock Depth Coverage Per Bag
2 inches Approx. 162 sq. ft.
3 inches Approx. 108 sq. ft.
4 inches Approx. 81 sq. ft.
6 inches Approx. 54 sq. ft.

For practical ordering, allow approximately 100 sq. ft. per bulk bag at a 3-inch depth. Because 40mm stone is larger than finer decorative gravel, an even layer of sufficient depth helps provide consistent coverage.

Landscaping with 40mm Washed Round Rock

40mm washed round rock is a popular choice for decorative landscaping where a larger natural stone appearance is desired. Its rounded shape and washed finish work well in garden beds, along landscape borders and around outdoor features.

For decorative ground cover, prepare and level the area before spreading the stone evenly. Appropriate landscape fabric or ground preparation can help reduce soil mixing and simplify maintenance. The finished depth should be suitable for the stone size and intended appearance.

Washed round rock may also be used in certain drainage areas or rock trenches. For engineered drainage systems, retaining wall backfill and other structural applications, confirm the required aggregate specifications before installation.

Frequently Asked Questions About 40mm Washed Round Rock

What is 40mm washed round rock used for?

40mm washed round rock is commonly used for decorative landscaping, garden beds, borders, natural stone features, ground cover and suitable drainage applications.

Is 40mm washed round rock the same as river rock?

Washed round rock is often referred to as river rock because of its naturally rounded appearance. Names can vary between suppliers, so compare the actual stone size, colour and appearance when selecting material.

What is the difference between 25mm and 40mm washed round rock?

25mm washed round rock has a smaller nominal stone size and produces a finer decorative appearance. The larger 40mm stone creates a more prominent rock texture and is often selected for decorative beds and natural stone features.

Is 40mm washed round rock good for drainage?

Washed round rock may be suitable for certain drainage applications because water can pass through the spaces between stones. The correct aggregate size and installation method depend on the drainage system and project requirements.

Each bulk bag contains approximately one cubic yard of washed round rock. At a 3-inch depth, allow approximately 100 square feet of coverage per bag for practical ordering.
