Everything You Need to Know About Retaining Walls

Retaining walls are more than just a landscaping feature — they’re a powerful tool for managing elevation, preventing erosion, and creating visually striking outdoor spaces. Whether you’re dealing with a sloped yard or want to add structure and interest to your garden, a properly built retaining wall can make a major difference.

At Greenbay Northern, we design and build custom retaining walls that are both functional and beautiful — tailored to Ontario’s unique climate and terrain.

Here’s everything you need to know.

What Is a Retaining Wall?

A retaining wall is a rigid structure built to hold back soil and create level areas on sloped or uneven land. They are essential in landscapes that:

  • Have hills or elevation changes
  • Need better drainage
  • Require terracing or structural support

Retaining walls also serve as seating areas, garden backdrops, or borders around interlocking patios.

🧱 Common Materials for Retaining Walls

Different materials serve different purposes. Some of the most popular choices include:

• Concrete Blocks

Durable, clean-lined, and ideal for modern or minimalist designs.

• Natural Stone

Rustic and elegant — great for blending with garden designs or heritage-style homes.

• Timber

Cost-effective and natural looking, though not as long-lasting in Ontario’s freeze-thaw cycles.

• Armour Stone

Large, rugged stone blocks perfect for high-impact visual appeal and erosion control.

We’ll help you choose the right material based on budget, style, and soil conditions.
