Pea Gravel vs Crushed Gravel: Key Differences in Calgary

If you are planning a landscaping project in Calgary, you will likely choose between pea gravel and crushed gravel. Both are common, but they work in different ways. The right choice depends on your project, ground conditions, and how you plan to use the space.

What is Pea Gravel

Pea gravel is small, smooth, and round. In Calgary, it is often sold as 10mm or 12mm washed round gravel. The stones come from natural water movement, which gives them their shape.

Because of this, pea gravel:

• Feels soft underfoot
• Has a clean, finished look
• Drains water well

It is often used for:

• Garden beds
• Play areas
• Dog runs
• Around patios and stepping stones

What is Crushed Gravel

Crushed gravel is made by breaking larger rock into smaller pieces. The stones have sharp edges and an uneven shape.

Because of this, crushed gravel:

• Locks together when compacted
• Creates a firm, stable surface
• Handles weight better

It is often used for:

• Driveways
• Base layers under patios
• Walkways that need to stay in place
• Areas with heavy traffic

Key Differences

Shape and Texture

Pea gravel is round and smooth. Crushed gravel is rough and angular. This affects how each one behaves on the ground.

Stability

Crushed gravel compacts and stays in place. Pea gravel shifts under pressure and does not lock together.

Drainage

Both drain well, but pea gravel allows water to pass through more freely. This works well in Calgary where drainage matters during snow melt.

Comfort

Pea gravel feels better to walk on. Crushed gravel feels firm but rough.

Appearance

Pea gravel has a clean, uniform look. Crushed gravel looks more rugged and natural.

What Works Best in Calgary

Calgary soil and weather play a role in your choice.

Use pea gravel when:

• You want a decorative finish
• You need good drainage
• The area has light foot traffic

Use crushed gravel when:

• You need a solid base
• The area will carry weight
• You want a surface that will not shift

For many projects, both materials work together. A common setup is crushed gravel as the base, with pea gravel on top for the finish.

Final Thoughts

Pea gravel and crushed gravel serve different purposes. One is better for looks and drainage. The other is better for strength and stability.
