7–10mm Round Rock Calgary | Decorative Pea Gravel
7–10mm Round Rock is a small, naturally rounded decorative stone commonly associated with pea gravel. Its smooth texture, mixed natural colours and smaller particle size make it a versatile choice for garden beds, pathways, landscape borders and outdoor features throughout Calgary and surrounding communities.
Also described as small round gravel or pea-sized decorative rock, this material creates a finer landscape finish than larger 20mm or 40mm round rock. Its rounded shape and natural appearance complement paving stones, garden plants and other landscaping materials.
Available loose by the cubic yard, 7–10mm Round Rock can be delivered directly to your property by dump truck.

- Approximately 7–10mm sizing provides a finer appearance than larger river rock
- Durable ground cover that does not decompose like organic mulch
- Suitable for decorative pathways and landscape borders
- Water can pass through spaces between the stones

Common Uses for Pea Gravel and Small Round Rock
- Decorative ground cover for garden beds
- Garden pathways and informal walkways
- Around stepping stones and patio borders

Small Round Rock vs. Pea Gravel
Pea gravel is a common name for small rounded stones used in landscaping. The term can refer to different size ranges depending on the supplier.
Our 7–10mm Round Rock falls within the small decorative gravel category and offers a naturally rounded appearance. The size makes it useful for creating a finer landscape finish than larger river rock products.
Because this is a natural aggregate, individual stone sizes, shapes and colours may vary between loads.
Installing 7–10mm Round Rock
Prepare the area by removing weeds, unwanted vegetation and debris. Grade the surface appropriately before spreading the decorative gravel.
Landscape fabric may be suitable for some decorative installations where separation from underlying soil is desired. Secure landscape edging can help keep small rounded stones contained.
Spread the material evenly to the desired depth. Approximately 2 to 3 inches is a common starting range for decorative applications, although the appropriate depth depends on the project.
For walkways, prepare a stable underlying surface and use edging to reduce gravel movement. Rounded gravel does not compact into a firm structural surface like road crush.
