Retaining Walls Canberra
Retaining walls can do much more than hold soil in place. They can manage changes in ground level, create usable space on sloping blocks, protect garden areas and become an important part of a larger landscape construction project.
At CanLandscape, we build and install retaining walls across Canberra and surrounding areas. With 11 years of experience in landscaping and retaining work, we work with different retaining wall systems and site conditions rather than trying to make every property fit the same solution.
From a small garden retaining wall to a larger wall forming part of a complete backyard landscaping project, we assess the property first and then determine the most practical approach. Our landscaping services in Canberra can also bring the surrounding garden, pathways and outdoor areas together as one coordinated project.

Retaining Wall Construction for Canberra Properties
Every retaining wall project is different.
A wall may be needed because a backyard slopes toward the house, a garden has several changes in level, soil is moving, water is running through an area or you want to create more usable outdoor space.
In many cases, the wall is only one part of the project.
Depending on the property, the work may also involve excavation and earthmoving, changing existing levels, drainage and irrigation, garden beds, paving and concreting, turf and planting, steps and access, and other landscape construction work.
For this reason, we don’t look at the wall in isolation. Instead, we consider how it will affect the rest of the property and how it needs to work with the finished landscape.
Retaining Walls Built Around Your Property
Canberra properties can have very different site conditions. Some blocks are relatively straightforward, while others have steep slopes, restricted access, existing gardens, established structures or significant changes in level.
Our retaining work can involve situations such as:
Sloping and uneven blocks
Changes in ground levels
Erosion and soil movement
Water runoff and drainage problems
Narrow or restricted site access
Existing gardens and landscaping
Excavation and soil removal
Tiered garden areas
Creating more usable space in sloping backyards
The reason for the wall matters just as much as the wall itself, particularly when it forms part of a wider landscape design.
For example, if you want to create a level area for a lawn, garden or entertaining space, the wall needs to work with the new levels and surrounding landscape design.
Similarly, if water is moving through the area, drainage needs to be considered as part of the project rather than treated as an afterthought.
Types of Retaining Walls We Build
There isn’t one retaining wall material that is automatically right for every property.
At CanLandscape, we build and install a range of retaining wall systems depending on the site, wall height, ground conditions, access, purpose and the appearance you want to achieve.

Concrete Sleeper Retaining Walls
Concrete sleepers can be a strong and durable option where longevity and relatively low maintenance are important.They can provide a clean, modern appearance and work well across a range of residential landscaping projects. However, their suitability depends on the individual site and what the wall needs to achieve.

Timber Sleeper Retaining Walls
Timber sleepers can provide a warmer, more natural appearance and work particularly well around gardens, planting and other landscape features.The right choice depends on the purpose of the wall, site conditions and the expected lifespan of the finished structure.

Concrete Block Retaining Walls
Concrete block walls can provide a substantial masonry solution and may be suitable for certain landscape and structural applications. Wall height, ground conditions and project requirements all need to be considered when determining whether this approach is appropriate.

Natural Stone, Sandstone and Rock Retaining Walls
Natural stone, sandstone and rock can create a more natural, established appearance and can work particularly well with gardens and other landscape features. The suitability of each option depends on the site, wall requirements, available space and the overall landscape design.

Brick Retaining Walls
Brick can be a suitable option where you want the wall to complement an existing home, brickwork or architectural style.The aim isn't simply to choose a material because it looks good. It also needs to suit the property and the job it is required to perform.

Besser Block Retaining Walls
Besser blocks can also be used where a more substantial block construction is appropriate.Their suitability depends on the specific site, the purpose of the wall and how the structure needs to be constructed.

Which Retaining Wall Is Right for Your Property?
Choosing the right retaining wall system is an important part of the planning process.
With 11 years of experience in landscaping and retaining work, we don’t believe every property should receive the same type of wall.
Before recommending an approach, we consider:
Wall height and length
Ground and soil conditions
Existing levels
Drainage and water movement
Access for machinery and materials
What the wall needs to support
The surrounding landscape
The appearance you want
Long term durability and maintenance
Budget
We consider the design, location, weather exposure, intended use, maintenance, appearance and budget before recommending an approach.
The aim isn’t to recommend a particular product simply because it is popular. We want the materials and finishes to make sense for the property and the way you intend to use the space.
Concrete Sleeper Retaining Walls
Concrete sleeper retaining walls are an important option for homeowners looking for a durable retaining solution with a clean appearance.
They can work particularly well where there is a significant change in level and a relatively low-maintenance finish is preferred.
However, choosing concrete sleepers isn’t simply a matter of deciding that they are stronger or better than every other option.
The wall still needs to suit the site.
Ground conditions, height, drainage, access and what is being retained all matter. We consider these factors alongside the wider landscape construction requirements before deciding whether a concrete sleeper retaining wall is appropriate for the project.

Retaining Walls for Sloping Blocks
Sloping blocks can present some of the biggest opportunities for retaining walls.
Instead of leaving a backyard with one difficult slope, retaining walls can be used as part of a broader landscape design to create different usable levels.
Depending on the property, this could allow you to create:
- Lawn areas
- Garden beds
- Terraced gardens
- Pathways
- Outdoor entertaining areas
- More practical access through the backyard
Creating these levels involves more than constructing the visible wall.
Excavation, soil removal, drainage, access and the relationship between the different levels all need to be considered.
As a result, retaining wall construction and broader landscape construction often need to work together.
Drainage and Site Preparation Matter
A retaining wall can look excellent when it is finished, but the work happening behind and underneath it is just as important.
Water movement needs to be considered because drainage can affect the conditions around a retaining wall.
Depending on the property, site preparation may involve:
- Clearing existing landscaping
- Excavating soil
- Removing excess material
- Preparing the ground
- Establishing required levels
- Considering drainage
- Working around existing structures
- Planning access for machinery and materials
We don’t treat construction as simply putting the visible wall together.
The finished wall is only one part of the job.
Proper preparation and consideration of the surrounding conditions are important when building a retaining solution suited to the property.

Our Retaining Wall Construction Process
Our process starts by understanding what you actually want to achieve.
Site Assessment
STEP 1
We assess the existing property, including levels, slope, access, ground conditions, drainage, gardens and surrounding structures.
Discuss Your Goals
STEP 2
Next, we talk through what you want the retaining wall to achieve and how you want the finished area to look and function.
Choose the Right Approach
STEP 3
Based on the property and project requirements, we discuss suitable retaining wall systems and materials.
Prepare the Site
STEP 4
Depending on the project, preparation may involve clearing, excavation, soil removal, level changes and preparation of the area.
Construct the Retaining Wall
STEP 5
We construct the wall using the selected system while considering the conditions around and behind the wall.
Backfill and Finish
STEP 6
Once the wall is constructed, we complete the surrounding area. Where the wall forms part of a larger landscaping project, this can include garden beds, planting, turf, paving or other outdoor works.
What Can Affect the Cost of a Retaining Wall?

There isn’t one fixed price for retaining walls in Canberra. Several factors can affect the final cost of a retaining wall in Canberra, including materials, access, excavation, drainage and the size of the project. For more practical advice, you can also explore our landscaping tips and project advice on the CanLandscape blog
The final cost can depend on factors such as:
- Wall height
- Wall length
- Material selected
- Ground conditions
- Excavation requirements
- Amount of soil to be removed
- Site access
- Drainage requirements
- Existing landscaping
- Design complexity
- Engineering or approval requirements where applicable
A small garden wall on an accessible, relatively level site can be very different from a larger retaining project on a steep block with restricted access and significant excavation.
For that reason, we prefer to assess the site and understand the actual scope before providing a quote.
