They can serve as retaining walls to manage slopes, as garden dividers, or as decorative features that add texture and character to your landscape. With options ranging from rugged rock and stacked stone to faux stone panels and limestone, there’s a solution for every style and budget.

How do you build a stone wall?

Building a stone wall starts with careful planning and a solid foundation. For retaining walls, which hold back soil and prevent erosion, it’s crucial to use the right materials and construction techniques. Here’s a step-by-step overview:

1. Plan and Measure: Outline the wall’s location using stakes and string or a garden hose to match your desired shape.

2. Excavate the Trench: Dig below the frost line (up to 4 feet in some regions) and at least 2 feet wider than your planned wall for stability.

3. Create a Stable Base: Line the trench with landscape fabric, then add and compact a 6-inch layer of crushed stone or gravel. This ensures proper drainage and prevents shifting.

4. Lay the First Course: Place the largest, flattest stones or blocks at the base. Use a mason’s line to keep everything level and straight.

5. Build Up and Stagger Joints: As you add layers, stagger the vertical joints for strength. Use mortar between stones for mortared walls, or dry-stack for a rustic look.

6. Backfill and Drainage: Add gravel behind the wall and install drainage pipes if needed to prevent water buildup, which is critical for retaining walls.

Tip: For walls over 4 feet, consult a professional to ensure safety and compliance with local building codes.

Natural Stone Walls

Natural stone walls use materials like limestone, sandstone, and granite for a classic, organic look. These stones are available in various shapes and sizes, from rough-cut rock to precision-cut blocks. Natural stone walls are ideal for garden borders, retaining walls, and textured landscape features.

Faux Stone Panels and Manufactured Walling

Faux stone panels and manufactured walling products offer the appearance of real stone with easier installation and lower cost. These panels are lightweight, durable, and available in a wide range of styles and colours, making them suitable for both interior and exterior use—including fireplaces, kitchens, and accent walls.

Interlocking and Armour Retaining Blocks

Interlocking retaining wall blocks are engineered for stability and easy installation. Made from concrete or stone, they lock together without mortar and are perfect for retaining applications in Canadian backyards. Armour stone, known for its size and strength, is often used for larger retaining and garden walls.

Armour Stone

Armour stone consists of large, natural limestone or granite blocks often used for robust retaining walls and garden features. Its heavy weight and irregular shape provide excellent stability and a rugged, natural look ideal for Canadian outdoor environments.

Peel and Stick Panels

Peel and stick panels are lightweight, adhesive-backed panels that make it easy to create a stone wall effect indoors or outdoors without mortar or special tools. They come in various textures and colours, offering a quick DIY solution for accent walls or even backsplashes.

FAQ

What type of mortar should be used for a stone wall?

Use a high-quality masonry mortar, such as air lime or hydraulic lime, for natural stone walls to ensure strength and flexibility in Canada’s freeze-thaw climate.

What is stone wall cladding?

Stone wall cladding involves applying thin stone or faux panels to an existing wall, creating a natural, stacked look without full masonry.

What is a dry stone wall?

A dry stone wall is built without mortar, relying on careful stacking for stability. These are ideal for garden walls and decorative features.

Stone walls are popular in Canadian gardens, as retaining features, around patios, and as interior accents in kitchens and fireplaces.
