Fencing on Retaining Walls: A Complete Guide for Edmonton Homes

A retaining wall can solve a major landscaping or grading challenge, but it can also make a fence installation more complicated. If you want to add a fence above or beside an existing retaining wall, fencing on retaining walls requires careful planning to ensure the fence is properly supported without compromising the wall.

For Edmonton homeowners, this matters even more because fences must withstand changing weather, freezing temperatures, snow, and seasonal ground movement. The right fence installation method depends on the retaining wall, available space, fence design, and how the fence posts can be supported.

At Atlantic Fence, we specialize in chain link fencing for residential, commercial, and industrial properties throughout Edmonton. Since 1980, our team has handled fence installation, repairs, removal, and relocation, giving local property owners practical experience with different site conditions.

Can You Install a Fence on a Retaining Wall?

Yes, but the fence should not simply be attached to the top of a retaining wall without considering how it will be supported.

A retaining wall is designed to hold back soil, while a fence must withstand forces such as wind and everyday use. When a fence is installed directly on or close to a retaining wall, these two structures can interact.

Before installation, consider:

  • The material and construction of the retaining wall

  • The condition of the wall

  • The height and design of the fence

  • Available space for fence posts

  • Drainage around the wall

  • Soil conditions

  • Gate locations

  • Local fencing requirements

The right solution will depend on the property. A professional fence contractor can assess the site and determine whether the fence should be installed on the wall, behind it, or beside it.

Why Fencing on Retaining Walls Requires Extra Planning

A standard fence is usually supported by posts installed into the ground. A retaining wall changes the available space and can limit where posts can be placed.

There is also another important factor: wind.

A fence acts as a structure that can receive wind pressure. The taller and more enclosed the fence, the more attention should be given to its support system. Even a chain link fence needs properly supported posts and connections.

This is why installing a fence on a retaining wall is not simply a matter of drilling into the wall and attaching a post.

The condition and construction of the existing wall should be considered first.

Chain Link Fencing on Retaining Walls

For Edmonton homeowners, chain link fencing can be a practical option when a property includes a retaining wall.

Chain link has an open mesh design, which allows air to pass through the fence. It is also durable, versatile, and relatively low maintenance. These characteristics make it suitable for many residential properties in Edmonton.

Atlantic Fence specializes in chain link fencing and offers residential fence installation, repair, removal, and relocation services. The company also offers galvanized and powder-coated chain link options for homeowners looking for different appearances and levels of corrosion resistance.

However, the type of fence is only one part of the project. The way the fence posts are supported is equally important.

3 Ways to Approach a Retaining Wall Fence

The appropriate installation method depends on the property and retaining wall.

1. Install the Fence Behind the Retaining Wall

If there is enough usable ground behind the retaining wall, fence posts may be installed independently of the wall.

This can be a practical solution because the fence has its own support rather than relying entirely on the retaining wall.

However, the available space and soil conditions need to be checked before installation.

2. Install the Fence Beside the Retaining Wall

In some properties, the fence can be positioned beside the retaining wall rather than directly on top of it.

This approach can be useful when the wall should remain structurally independent from the fence.

The exact position will depend on the property layout, boundary lines, drainage, and available space.

3. Attach the Fence to a Suitable Existing Structure

Some retaining-wall systems may be capable of supporting a fence connection. However, this should be determined on a site-by-site basis.

Before drilling or anchoring anything, the construction and condition of the wall should be understood.

A fence contractor should also avoid interfering with drainage systems or other components that help the retaining wall function properly.

Check the Retaining Wall Before Installing a Fence

One of the most important steps is checking the existing retaining wall.

Look for signs such as:

  • Cracks

  • Leaning

  • Bulging

  • Loose blocks

  • Movement

  • Soil displacement

  • Water buildup

  • Poor drainage

  • Deteriorated materials

If the wall already appears unstable, installing a new fence should not be the first step.

Atlantic Fence focuses on fencing services rather than retaining-wall construction or structural repair. If the wall itself requires structural work, homeowners may need to have that issue addressed by an appropriate retaining-wall or structural professional before proceeding with the fence.

Once the wall is suitable for the project, a fencing contractor can focus on the fence design and installation.

Drainage Is Important

Retaining walls need appropriate drainage to manage water behind the structure.

Fence installation should therefore be planned carefully so that digging, post installation, or other work does not unnecessarily interfere with existing drainage.

This is particularly important in Edmonton, where snow and seasonal moisture can contribute to changing ground conditions.

Before installing the fence, identify where drainage systems, underground utilities, and other important features are located.

Choosing the Right Fence Height

Fence height is another important consideration when installing fencing near a retaining wall.

A fence installed above a wall effectively increases the overall height of the barrier. Depending on the property and location, local requirements may apply.

Atlantic Fence notes that Edmonton fence requirements can vary according to fence height and location, so homeowners should confirm the current requirements that apply to their property before starting construction.

It is also important to consider how the finished fence will look from both sides of the property.

Why Chain Link Works Well for Many Edmonton Properties

Chain link fencing is widely used for residential, commercial, and industrial applications because it offers a combination of durability, flexibility, and relatively low maintenance.

For a residential retaining-wall project, chain link can provide:

  • A clear property boundary

  • Security around the yard

  • Visibility through the fence

  • Low-maintenance performance

  • Flexible design options

  • Galvanized or powder-coated finishes

Atlantic Fence offers both galvanized and powder-coated chain link fencing, with powder coating available in several colours.

This gives Edmonton homeowners the option to choose a fence that works with the appearance of their property without moving away from a chain-link fencing system.

Residential Fencing on Retaining Walls

For homeowners, the goal is usually a combination of safety, security, privacy, and appearance.

A retaining wall may already separate two levels of a yard, making the addition of a fence useful for creating a safer boundary around the property.

For example, a homeowner may have:

  • A raised backyard

  • A sloped property

  • A retaining wall along the property line

  • A patio or landscaped area above the wall

  • A need for a secure boundary for children or pets

In these situations, the fence needs to follow the property's layout while maintaining proper support.

Atlantic Fence provides residential fencing solutions in Edmonton and can help homeowners determine an appropriate chain-link fencing option for their property.

Commercial and Industrial Retaining-Wall Fencing

Retaining-wall fencing is not limited to residential properties.

Commercial and industrial properties may have retaining walls around parking areas, loading areas, sloped sites, storage spaces, or perimeter boundaries.

In these applications, the fence may have additional security requirements.

Atlantic Fence provides commercial and industrial fencing solutions in Edmonton, including perimeter fencing and custom fencing applications. Its industrial fencing services include different pipe options based on project requirements.

For higher-security applications, Atlantic Fence also offers high-security fencing and metal cladding options that can be added to existing chain-link fencing in suitable situations.

What About Gates on Retaining Walls?

Gates require additional consideration.

A gate moves repeatedly and places different demands on its supporting posts compared with a standard fence section. This becomes particularly important when the gate is located close to a retaining wall.

Before installing a gate, consider:

  • Gate width

  • Gate weight

  • Post support

  • Available clearance

  • Ground slope

  • Retaining-wall location

  • Gate opening direction

Atlantic Fence also provides gate-related services, including gate operators and automatic gate opener installation for suitable applications.

Common Mistakes to Avoid

Attaching Posts Without Checking the Wall

A retaining wall may look strong but still have limitations. Do not assume that any wall can support a fence.

Blocking Drainage

Avoid installing posts or concrete where they could interfere with the wall's drainage system.

Ignoring Property Boundaries

A fence should be positioned according to the actual property boundary rather than simply following the retaining wall.

Choosing the Fence Before Assessing the Site

The available space and retaining-wall design can influence which fencing method is practical.

Installing a Fence on a Damaged Wall

If the wall is leaning, cracking, or moving, address the structural concern before installing the fence.

When Should You Call a Professional?

Professional help is particularly useful when:

  • The retaining wall is tall or complex

  • There is limited space for fence posts

  • The fence will be installed directly beside the wall

  • A gate is involved

  • The property has significant elevation changes

  • Drainage is present near the wall

  • The existing fence needs removal or relocation

  • You are unsure how the fence should be supported

A site assessment allows the fencing contractor to understand the property before recommending an installation approach.

Fencing on Retaining Walls: What Edmonton Homeowners Should Know

The biggest takeaway is simple: the fence and retaining wall should be treated as related but separate parts of the project unless the structure has specifically been designed to support the fence.

A successful installation starts with understanding the existing wall, available space, drainage, fence height, and required support.

For Edmonton homeowners looking for a durable fencing solution, chain link is one option worth considering. Atlantic Fence specializes in chain-link fencing for residential, commercial, and industrial properties, along with fence repair, removal, relocation, powder coating, and high-security solutions.

Frequently Asked Questions

Can I put a chain link fence on top of a retaining wall?

It may be possible, but the retaining wall must be suitable for the proposed installation. The fence should have adequate structural support, and installation should not compromise the wall or its drainage.

What is the best fence for a retaining wall in Edmonton?

There is no single option for every property. Chain link can be a practical choice because it is durable, versatile, and available in galvanized and powder-coated finishes. The installation method is just as important as the fence material.

Can fence posts be installed behind a retaining wall?

If sufficient space and suitable ground are available, installing posts behind the wall may allow the fence to have independent support. The site should be assessed before digging.

Does Atlantic Fence install retaining walls?

Atlantic Fence specializes in fencing rather than retaining-wall construction. If your retaining wall needs structural repair or rebuilding, you should address that work with an appropriate specialist before proceeding with the fence installation.

Aluminum vs Vinyl Fencing: Which Is Better for Edmonton Winters?

Edmonton winters don't play fair. Temperatures swing from -30°C to a chinook-driven +5°C within days, and that freeze-thaw cycle is brutal on outdoor structures — fences included. If you're comparing aluminum vs vinyl fencing for a property in the Edmonton area, the decision comes down to how each material actually behaves once the ground starts heaving and the frost gets into everything.

After years of installing and repairing both fence types across Edmonton neighborhoods — from Windermere to Sherwood Park — we've seen firsthand which materials shrug off winter and which ones crack under pressure. This guide breaks down the real differences so you can choose with confidence, not guesswork.

Aluminum vs Vinyl Fencing: The Quick Answer

For most Edmonton properties, aluminum fencing performs better in winter conditions than vinyl. Aluminum doesn't become brittle in extreme cold, it flexes slightly with ground movement instead of cracking, and it holds its shape through decades of freeze-thaw cycles.

Vinyl fencing isn't a bad product — it's low-maintenance and looks great in warmer climates — but Edmonton's deep frost line and sudden cold snaps expose its biggest weakness: brittleness below -20°C.

That said, the "better" choice still depends on your budget, your yard's soil conditions, and what you're using the fence for. Let's get into the details.

How Cold Affects Fencing Materials

Edmonton sits in a climate zone where ground frost can penetrate more than 2 metres deep during a hard winter. That depth matters because it directly affects how much your fence posts shift each year.

What Happens to Vinyl in Extreme Cold

Vinyl (PVC) fencing is made from a polymer that stiffens as temperatures drop. Below roughly -20°C, vinyl loses much of its natural flexibility.

  • A vinyl panel that would simply bend under impact in summer can shatter in January.

  • Kids playing near a fence, a shovel bumping a post while clearing snow, or a wind-blown branch can all cause cracking that wouldn't happen in July.

  • Once vinyl cracks, the damaged section usually needs full panel replacement — you can't patch it invisibly.

What Happens to Aluminum in Extreme Cold

Aluminum doesn't undergo the same molecular stiffening. It stays structurally consistent across temperature swings, which is why it's the material of choice for commercial and municipal fencing across Alberta.

  • It won't crack, chip, or shatter from cold-weather impact.

  • Powder-coated finishes resist chalking and fading through UV exposure and salt spray from winter road treatments.

  • Aluminum posts handle frost heave better because the material itself doesn't degrade — the main risk is post movement, which is a footing issue, not a material issue.

Frost Heave: The Real Edmonton Problem

Most fence failures in Edmonton aren't actually about the fencing material — they're about frost heave, where water in the soil freezes, expands, and pushes posts upward or sideways.

This affects aluminum and vinyl fences equally if the posts aren't installed correctly. The fix isn't about which material you choose; it's about installation depth.

  • Posts should be set below the frost line, typically at least 1.2 metres (4 feet) deep in the Edmonton region.

  • Concrete footings should be poured with a slight taper (narrower at the top) so frost pressure pushes up and around rather than lifting the post directly.

  • Proper drainage around the base reduces how much water sits and freezes near the post.

We've corrected far more leaning fences caused by shallow post depth than by material failure — regardless of whether the fence was aluminum or vinyl.

Cost Comparison: Aluminum vs Vinyl Fencing

Upfront price is often the deciding factor, so here's a realistic breakdown for an Edmonton residential installation.

FactorAluminumVinylMaterial cost per linear foot$35–$60$25–$45Installation cost (average lot)Moderate–HighModerateExpected lifespan30–50 years20–30 yearsWinter repair frequencyLowModerateResale/curb appeal impactHighModerate–High

Vinyl typically wins on initial purchase price. Aluminum tends to win on total cost of ownership once you factor in fewer cold-weather repairs and a longer service life.

Maintenance Through an Edmonton Winter

Neither material needs painting or staining, which is why both are popular alternatives to wood. But their winter maintenance needs differ slightly.

Aluminum fencing maintenance:

  • Rinse off road salt residue in spring to protect the powder coating

  • Check gate hinges and latches for stiffness after deep freezes

  • Inspect post caps for ice buildup that can trap moisture

Vinyl fencing maintenance:

  • Avoid leaning shovels, snowblowers, or heavy snow piles directly against panels

  • Inspect for hairline cracks after any hard frost or high-wind event

  • Clear snow load off horizontal rails to prevent stress points

Which One Should You Choose?

Think about how you'll use the fence and what matters most to your household.

  • Choose aluminum if: you want maximum durability, you're fencing a pool or pet area where impact resistance matters, or you're planning to stay in the home long-term.

  • Choose vinyl if: your budget is tighter, your yard has less foot traffic near the fence line, and you're comfortable with a slightly shorter lifespan.

  • Avoid either (short-term) if your yard has known drainage or heaving issues — get those addressed first, since no fence material fixes a bad base.

Frequently Asked Questions

Does vinyl fencing crack in Edmonton winters? Yes, it can. Vinyl becomes more brittle below about -20°C, and direct impact — from snow removal equipment, falling branches, or accidental contact — is more likely to cause cracking than it would be in warmer months.

Is aluminum fencing worth the extra cost in Alberta? For most homeowners planning to stay put for 10+ years, yes. Aluminum's longer lifespan and lower winter repair rate usually offset the higher upfront material cost over time.

How deep do fence posts need to be in Edmonton? Posts should generally be set at least 1.2 metres (4 feet) deep, below the local frost line, with properly poured and tapered concrete footings to resist frost heave.

Can I install a vinyl fence in winter in Edmonton? It's possible but not ideal. Frozen ground makes post-hole digging difficult and costly, and installers may recommend waiting for a spring or fall install window for better footing conditions.

Which fence type adds more resale value? Both aluminum and vinyl are viewed favorably by buyers over wood, since neither requires ongoing staining or painting. Aluminum often edges ahead in higher-end neighborhoods due to its more substantial, upscale appearance.

Final Thoughts

If Edmonton winters are your main concern, aluminum fencing is the more resilient choice — it resists cracking, holds its finish, and lasts through decades of freeze-thaw cycles with minimal upkeep. Vinyl remains a solid, budget-friendly option, but it demands a bit more care once temperatures drop.

Whichever material fits your property and budget, correct installation depth matters more than almost anything else for surviving an Edmonton winter without a leaning or damaged fence.
