Landscaping with Concrete Retaining Walls: Expert Tips from West Key Builders
When it comes to improving outdoor spaces, landscaping with concrete retaining walls is one of the most effective and visually striking solutions. Not only do these walls create structure and definition in sloped or uneven yards, but they also help prevent erosion and increase usable space. At West Key Builders, we specialize in designing and building retaining walls that are both functional and attractive, adding lasting value to your landscape.
In this guide, we’ll walk you through what you need to know to get started with your retaining wall project—from planning to materials and construction techniques.
Planning Is Essential When Landscaping with Concrete Retaining Walls
Before building, it’s important to define your purpose. Are you using the wall for erosion control, to create garden beds, or to enhance curb appeal? The goal behind your project will influence design, wall height, materials, and construction method.
Conduct a Site Assessment
Take time to evaluate your yard’s slope, soil type, drainage paths, and potential underground utilities. These factors will determine the footing depth, wall thickness, and backfill materials needed. If you’re considering a structure taller than four feet, consult an engineer for a safe and compliant design—especially since local codes may require permits.
At West Key Builders, we help clients in London, Ontario navigate all regulatory and technical requirements involved in landscaping with concrete retaining walls.
Choosing the Right Materials for Your Retaining Wall
Material selection plays a big role in both function and aesthetics.
-
Precast Concrete Blocks
These are a go-to choice for homeowners. They come in various sizes, textures, and colors, offering creative flexibility with easier stacking and minimal formwork. -
Poured Concrete
Ideal for a modern, clean look, poured concrete offers a smooth, continuous surface. However, it requires formwork and proper curing to prevent cracking. -
Reinforcement Matters
Reinforcing materials such as rebar, welded wire mesh, or geogrids add vital strength—especially for taller or load-bearing walls.
We use high-quality materials in all of our concrete poured retaining walls to ensure your wall withstands pressure and time.
Drainage and Foundation: The Backbone of a Solid Wall
When landscaping with concrete retaining walls, poor drainage is a common cause of failure. Water trapped behind the wall increases pressure and can lead to cracking or collapse.
Drainage Tips:
-
Install a perforated drain pipe behind the base of the wall.
-
Use clean gravel backfill for quick water flow.
-
Add weeping holes at intervals to allow excess moisture to escape.
Footing and Base Preparation:
-
Dig a trench deep enough to support the wall’s weight and resist frost heave.
-
Use compacted gravel or crushed stone to form a level, stable base.
-
For poured concrete walls, we follow strict reinforcement and curing practices to ensure structural integrity.
Construction and Finishing Considerations
Whether you’re stacking blocks or using poured concrete, follow all manufacturer instructions or engineering plans for:
-
Stacking or formwork techniques
-
Concrete curing time
-
Backfilling in layers and compacting as you go
We always ensure proper compaction and backfill to prevent shifting. Our team also recommends using heavy-duty geotextiles behind walls to separate soil from drainage layers.
If you’re looking to incorporate the wall into a larger outdoor upgrade, we can also integrate concrete patios or landscaping features for a cohesive finish.
Safety, Tools, and When to Call the Pros
While DIY is possible for small retaining walls, taller or load-bearing walls demand more skill.
-
Wear PPE: Gloves, safety glasses, and steel-toe boots are essential.
-
Rent Equipment: Consider renting a plate compactor, laser level, or concrete mixer for better results.
-
Hire a Professional: For complex designs, hire an experienced contractor. At West Key Builders, we offer safe, efficient solutions tailored to your property.
