4–14mm River Rock Calgary | Decorative River Stone
Create a natural landscape finish with 4–14mm River Rock from Direct Landscape Supply. This small, rounded decorative stone features a blend of natural colours and sizes, making it a versatile choice for garden beds, landscape borders and outdoor features.
The approximately 4–14mm size range creates a finer, more uniform appearance than larger river rock. Its smooth, rounded texture works well in both contemporary and traditional landscape designs.
Available loose by the cubic yard, our river rock can be delivered by dump truck throughout Calgary and surrounding communities.
Why Choose 4–14mm River Rock?
- Natural rounded stones with a smooth appearance
- Blended 4–14mm sizing for a finer decorative finish
- Mixed natural colours complement a variety of landscapes
- Durable decorative ground cover that does not decompose like mulch
- Suitable for garden beds, borders and outdoor accents
- Works with modern and natural landscape designs
- Available by the cubic yard with loose bulk delivery
Common Uses for Small River Rock
- Decorative ground cover for garden beds
- Landscape borders and edging areas
- Around patios, pavers and stepping stones
- Decorative pathways with suitable edging and preparation
- Rock gardens and natural landscape features
- Decorative accents around water features
- Residential and commercial landscaping
River rock is primarily a decorative material. Because the stones are rounded, they do not compact into a firm structural base like road crush. For engineered drainage installations, confirm the required aggregate specifications before ordering.

River Rock Coverage Guide
One cubic yard of river rock provides approximately the following coverage at different depths:

| 3 inches | Approx. 108 sq. ft. |

Coverage figures are mathematical volume estimates, not recommended depths for every application. For general planning, allow approximately 100 square feet per cubic yard at 3 inches deep.
Natural River Stone for Landscaping
River rock is valued for its rounded shape and natural colour variation. Unlike angular crushed stone, rounded river stones create a softer, more natural-looking landscape finish.
The 4–14mm blend is particularly useful where a smaller decorative stone is preferred. It can provide a refined appearance around patios, landscape borders and planting areas.
Natural stone colour and size can vary between loads. The appearance may also change when the material is wet or dry.
Installing 4–14mm River Rock
- Remove weeds, debris and unwanted vegetation from the installation area.
- Grade and prepare the underlying surface. Address drainage concerns before placing the rock.
- Consider suitable landscape fabric where separation from the underlying soil is desired.
- Install landscape edging where needed to contain the rounded stone.
- Spread the river rock evenly to the desired depth. Approximately 2–3 inches is a common starting point for decorative installations.
- Rake the surface to create a consistent decorative finish.
Rounded stone can shift underfoot, particularly in areas with frequent pedestrian traffic. For heavily used pathways, consider whether a compactable aggregate or another walking-surface material would be more suitable.
