Wondering if a retaining wall fence is more about looks or functionality?
(Hint = it’s both). Retaining walls are ideal for holding back soil, creating usable space on the slope, and preventing erosion.
That’s why they are also great for adding style and functionality to your yard. However, it can be a bit challenging to build a fence on top of retaining wall. With a retaining wall fence, you get privacy, security, and an aesthetic upgrade all at once.
Since it’s not easy to build a retaining wall fence, you need to learn and understand the entire process carefully so you can manage things easily.
Why You Should Combine a Retaining Wall and Fence?
Before we learn the steps to build a fence on top of retaining wall, we need to understand why you should even combine a retaining wall and fence?

A fence on top of a retaining wall gives you more seclusion from neighbors.
-

It acts as a barrier, which is important if you have kids playing in the yard.
-
Erosion Control
Retaining walls stop soil from sliding downhill, which protects landscaping.

Things to Consider Before You Build a Fence Retaining Wall
Building a retaining wall fence is not any kind of weekend project that can be started and finished in a day. You need to consider some important things before building a retaining wall with fence.
-
Local Building Codes
Make sure there are no height restrictions for both fences and retaining walls.
-
Soil Type
Clay, sandy, or rocky soil will determine how you prepare your foundation.
-
Drainage Needs
Plan for water flow because poor drainage can make walls collapse over time.
-
Material Choices
You’ll need to pick durable materials for both the wall and the fence.
-
Budget & Timeline
Materials, tools, and labor (if you hire help) all add up.
-
DIY vs. Pro Help
Small walls (under 4 feet) are often DIY-friendly. But taller walls with fences may require professional assistance. So, decide carefully.
Step-by-Step Guide to Building a Retaining Wall Fence
Let’s start with a step-by-step guide to build a fence and retaining wall.
-
Think About the Fence on Retaining Wall Design:
First, you need to plan things carefully. Draw your yard, the slope, and where you want the wall and fence. Now it’s time to decide the height of the fence. How tall should the wall be? How high do you want the fence above it?
After that, choose materials. For a retaining wall, you have options including concrete blocks, natural stone, timber, and poured concrete. And for fences, you have options including wood, vinyl, metal, or composite.
Also, do not forget to think about the style. Match the design with your home. Whether it’s rustic, modern, or sleek.
-
Gather Necessary Tools and Materials:
In the next step, you need to gather some required tools and materials.
Tools:
- Shovel
- Wheelbarrow
- Level
- Tape measure
- Tamper or plate compactor
- Circular saw (if using wood)
- Drill and masonry bit (if attaching posts to concrete)
- Hammer or mallet
Materials:
- Retaining wall blocks, stones, or treated timber
- Gravel and sand (for base and drainage)
- Landscape fabric
- Rebar or geogrid (for reinforcement if needed)
- Fence posts (wood, metal, or vinyl)
- Concrete mix (for setting posts)
- Screws, brackets, or post anchors
-
Excavate and Prepare the Base:
We all know one thing about foundation – it can make or break your retaining wall’s looks. So, carefully mark the area with stakes and string.
After that, dig a trench that’s wide enough for your wall blocks (plus 6 inches) and deep enough to hold at least 6 inches of compacted gravel.
Make sure to compact the base soil using a tamper. And then add gravel and compact it in layers until firm.
-
Install the Retaining Wall:
Now this is the most important yet fun part of the process – installing a retaining wall. Here’s how it should be done:
-
First Row Matters Most:
Lay the first course of blocks on the compacted base. It should be perfectly leveled.
-
Stack with Care:
Place the next rows, staggering the joints for strength.
-
Backfill as You Go:
After each row, add gravel and soil behind the wall, compacting it to reduce pressure later.
-
Drainage Is Key:
Lay perforated drainage pipe behind the bottom course and cover it with gravel.
-
Reinforce Tall Walls:
If your wall is more than 3 feet tall, consider geogrid reinforcement every few courses.
-
Add the Fence Posts:
Now that the retaining wall is all set, it’s time to add the fence posts. There are two options to do it.
Option 1: Set Fence Posts Behind the Wall
In this option, you need to dig post holes just behind the wall. Set posts in concrete. And attach your fence panels to the posts.
Option 2: Core-Drill into the Wall
In the next option, you can drill holes into the top of concrete blocks. Insert metal post brackets or sleeves, and then set fence posts directly into the wall.
-
Build the Fence Panels
Once the posts are added, you can attach the panels.
- Wood Fence: Nail or screw planks horizontally or vertically.
- Vinyl Fence: Snap panels into the post slots.
- Metal Fence: Attach panels using brackets or bolts.
- Composite Fence: Assemble per manufacturer’s instructions.
-
Backfill and Finish the Top
Add more soil and gravel behind the wall to the final grade. Cover drainage areas with landscape fabric to prevent clogs. Now cap the top of the wall with decorative stones, timbers, or coping. You can even paint, stain, or seal the fence for durability.

How to Maintain a Retaining Wall and Fence?
After building a retaining wall, you want to maintain it so it can last for years. Here’s how to do it:
- Inspect yearly for cracks
- Reapply sealant to wood every 2–3 years.
- Keep drainage outlets clear of debris.
- Remove weeds or roots that may push against the wall.
- Tighten fence screws and brackets if they loosen.
DIY vs. Professional – What’s More Ideal?
| DIY | Professional help |
| Good for small walls (under 4 ft) | Best for tall or complex walls |
| Cheaper, but takes more time | Costs more, but faster and easier |
| Full control of the project | Expert design, safer build |
| Risk of mistakes | Low risk, often with warranties |
Now that you have analyzed both – DIY and professional help. Based on the analysis, it’s much better to consider professional help as it involves no risk, expert design, and fast completion.
Common Mistakes to Avoid:
Here are a few mistakes to avoid while building a retaining wall fence:
- Skipping drainage
- No reinforcement
- Uneven base
