By E.L. Empire Landscaping Ltd.
If you own a home in Kelowna or anywhere in the Okanagan Valley, you know our landscapes come with their own set of challenges. Hot, dry summers, freeze-thaw cycles in the winter, and sloped properties with changing elevations are all things that need to be considered when building a landscape that is meant to last.
Retaining walls are one of the most common features we install at Empire Landscaping, and they are also one of the areas where proper installation matters the most. A retaining wall is not just stacking blocks and hoping they stay in place. The base preparation, drainage, materials, and installation process all play a major role in how that wall performs years down the road.
We have seen firsthand what happens when retaining walls are not built properly... shifting blocks, poor drainage, settling, and costly repairs. That is why we focus on doing things the right way from the beginning.
Why Retaining Walls Are So Common in Kelowna
Many Okanagan properties are built on slopes, especially in areas like Upper Mission, Wilden, West Kelowna, McKinley, and other hillside communities. While these properties often have incredible views, they can also create challenges when it comes to creating functional outdoor spaces.
Retaining walls allow homeowners to:
Create more usable backyard space
Build level areas for patios and entertaining
Improve drainage and control erosion
Add structure and definition to the landscape
Create planting areas and garden spaces
A well-designed retaining wall is not just a functional piece of your landscape; it can become one of the features that ties the entire property together.

Understanding Kelowna’s Freeze-Thaw Conditions
One of the biggest factors we consider when building retaining walls in Kelowna is our changing weather conditions.
During the winter months, moisture in the soil behind a retaining wall can freeze and expand. As temperatures rise and fall, that repeated movement creates pressure against the wall. If the wall does not have proper drainage and a stable foundation, it can eventually begin to move.
This is why a retaining wall installation is about much more than the block you see on the surface.
The most important parts of a retaining wall are often the parts you never see:
Proper excavation
A compacted granular base
Drainage rock behind the wall
Perforated drainpipe
Geogrid reinforcement when required
Proper backfill and compaction
These steps are what allow the wall to perform year after year.
Choosing the Right Retaining Wall Material
There are many different retaining wall products available, and choosing the right one depends on your property, design goals, and how the wall will be used.
At Empire, we work with a variety of quality retaining wall systems, including products from manufacturers like Barkman, Basalite, and Techo-Bloc.
Segmental/Unit Retaining Walls
Segmental and unit retaining walls are one of the most popular options for Kelowna homes. They offer durability, a wide range of colours and textures, and the ability to create everything from small garden walls to larger structural applications.
They are a great choice for:
Backyard transformations
Tiered landscapes
Patio expansions
Driveway and entry improvements
Natural Stone Retaining Walls
For homeowners looking for a more natural or timeless look, natural stone can create a beautiful transition between the landscape and surrounding environment.
Natural stone walls can add character and blend seamlessly with Okanagan landscapes, especially when paired with thoughtful planting and lighting. The type of stone used for these walls can be selected to complement your home and overall landscape style. With Kelowna being surrounded by local quarries, there are many different options available.
Drainage Is What Makes a Retaining Wall Last
One of the biggest mistakes we see with retaining walls is overlooking drainage.
Water is one of the strongest forces working against a retaining wall. Without a proper drainage system, water pressure can build up behind the wall and eventually cause movement or failure.
A properly installed retaining wall includes drainage solutions that allow water to move away from the structure and ensure that water is not sitting in one location.
At Empire, we take the time to properly prepare every wall we build because we know that the quality of the installation is what determines how it performs long term.
Common Retaining Wall Mistakes We See in Kelowna
A retaining wall can be one of the biggest investments in a landscape, and unfortunately, many issues we see come from shortcuts taken during installation.
One of the most common mistakes is focusing only on the visible portion of the wall. The block, colour, and finished appearance are important, but they are only one part of the overall system. A retaining wall is only as strong as the preparation underneath it.
Some common issues we see include:
Installing directly on unstable soil instead of a properly compacted base
Not accounting for drainage behind the wall
Using the wrong wall system for the height or application
Poor compaction behind the wall
Failing to consider how water moves through the property
In Kelowna, these issues can become even more noticeable because of our changing seasons. A wall that appears fine immediately after installation can begin showing signs of failure after several freeze-thaw cycles if it was not designed and installed properly.
Taking the time to complete the installation correctly from the beginning helps protect your investment and ensures the wall continues to perform for years to come.
Retaining Walls Are More Than Just Functional
While retaining walls are often installed because a property needs a solution for elevation changes, they can also become an important design element within your landscape.
A thoughtfully designed retaining wall can help create defined outdoor spaces, improve the flow of your yard, and make areas of your property that were previously difficult to use much more functional.
Many of the projects we complete in Kelowna involve more than simply installing a wall. We look at how the retaining wall works together with patios, planting, irrigation, lighting, and outdoor living spaces.
The best retaining walls do not feel like a separate structure added to your yard. They feel like they were designed specifically for your property.
Why Local Experience Matters When Building Retaining Walls
Every region has different challenges when it comes to landscape construction. A retaining wall that works in another part of British Columbia may not be the best solution for a property in the Okanagan.
Working locally means understanding the conditions that impact landscape construction in our area, including:
Okanagan soil conditions
Dry summers and irrigation requirements
Freeze-thaw cycles
Sloped properties and elevation changes
Local materials and suppliers
At Empire Landscaping, we have been building landscapes throughout Kelowna and the Okanagan Valley since 2004. Our goal has always been simple: build outdoor spaces that look great, function properly, and stand the test of time.
