How We Design and Install Retaining Walls
The Purpose of a Retaining Wall
A retaining wall serves a crucial function in landscaping, providing structural support by holding back soil or aggregate. These walls are commonly used for:
Modifying elevation – Creating leveled areas on sloped properties.
Foundation protection – Preventing soil erosion and stabilizing the ground around buildings or structures.
Enhancing outdoor spaces – Acting as the backbone for features like outdoor kitchens, fire pits, raised flower beds, or garden terraces.
One of the primary reasons retaining walls fail is poor drainage. When water accumulates behind the wall—especially in freezing conditions—it exerts pressure that can lead to cracks, shifting, or collapse. This often results from improper construction methods and the use of non-permeable backfill materials that trap moisture.
How We Build Durable Retaining Walls
To prevent water buildup and ensure long-term stability, we use 3/4 clear gravel as backfill behind the wall. This material allows water to drain effectively, directing it downward to weeping tile or drainage pipes, which carry excess moisture away and alleviate pressure on the structure.
Proper foundation preparation is also essential. Retaining walls should never be built directly on soil—a gravel base of 6 to 12 inches is necessary to provide stability, with a geotextile layer to separate the soil from the base. Additionally, concrete or interlocking block retaining walls over 3 feet high require a concrete base with geogrid reinforcement to support their weight and prevent shifting over time.

Expert Retaining Wall Contractor in Toronto
Enhance your outdoor space with a professionally installed retaining wall that offers both structural support and aesthetic appeal. Retaining walls are available in various materials, styles, and sizes, allowing you to find the perfect fit for your landscape. Not only do they help prevent soil erosion and improve drainage, but they also create visually striking features like raised garden beds, outdoor seating areas, and decorative borders.
Built for durability, retaining walls require minimal maintenance, ensuring they remain strong and intact for years to come. If you’re looking for a practical yet stylish way to upgrade your yard, consider a custom-built retaining wall that blends functionality with long-lasting beauty.
Retaining Wall Installation
Retaining walls can be built using four primary methods: gravity walls, piling walls, cantilever walls, and anchored walls. In landscaping, gravity and cantilever retaining walls are the most commonly used due to their strength and reliability.
Gravity retaining walls rely on their own weight and a solid base for stability. They can be constructed using concrete blocks or natural stone. These materials may be bonded together with construction adhesive or cement for added durability.
Cantilever retaining walls, on the other hand, are reinforced with concrete or mortared masonry. They feature additional support from the back or front to enhance their strength and longevity, making them ideal for handling significant soil pressure while maintaining a clean and modern look.
