A well-built retaining wall can transform sloped or uneven ground into a sturdy, eye-catching feature in your yard. It adds structure, creates usable space, and sets the stage for other outdoor upgrades. Whether you’re looking to support patios and fences or improve drainage and curb appeal, retaining wall construction is a smart investment for a more functional and beautiful outdoor living area.
Below, we’ll walk you through the key things to know before starting your project — from choosing materials and design considerations to permits and professional guidance.
Benefits of Retaining Wall Installation
A retaining wall is a structural barrier built to hold back soil on sloped ground. Commonly found along roadsides, in hillside farming, and in residential landscaping, these walls prevent soil erosion and provide necessary support for uneven terrain. According to the International Building Code, retaining walls should be constructed with a safety factor of 1.5, ensuring stability against sliding, overturning, and excessive base pressure.
What a Retaining Wall Does for Your Yard
Before building a retaining wall — especially if you plan to install a fence on top — you need to determine its primary function. The wall’s purpose influences every decision, from its height and material to drainage systems and reinforcement.
Here are some of the common reasons for building a retaining wall:
- Holding Back Soil on Sloped Properties: Retaining walls provide critical support in yards with elevation changes. They keep soil from shifting or sliding, especially after heavy rain.
- Preventing Erosion and Managing Drainage: Water runoff can wash away topsoil and damage your landscape without proper barriers. A well-built wall helps slow and redirect water to protect your yard and foundation.
- Creating Level Spaces for Patios, Play Areas, or Gardens: Retaining walls can flatten parts of your yard, making room for outdoor seating, playgrounds, or raised garden beds. This makes your outdoor space more usable and safe.
- Supporting a Fence Retaining Wall System: A retaining wall for a fence can provide a stable, level base if you’re installing a fence on uneven ground. It also helps reduce wear and pressure on the fence over time.
- Improving Your Yard’s Overall Look and Value: A clean, structured landscape adds visual appeal. Retaining walls create clear lines and tidy transitions, making your entire yard feel more finished — and more valuable to buyers.
Choosing the Right Material for Your Retaining Wall
Different materials serve different needs in this type of construction. Your choice will affect how strong the wall is, how long it lasts, and how well it fits the rest of your outdoor space.
Here are some of the popular material options offered by trusted contractors:
- Concrete Blocks: Strong, uniform, and easy to stack. Concrete blocks are great for durability and longevity in retaining walls.
- Natural Stone: Offers a high-end look and blends well with gardens and patios.
- Poured Concrete: Provides a clean and solid look, but it does require professional installation.
- Wood: More affordable and easy to install, but it doesn’t last as long as other materials in outdoor environments.
Things to Consider: Following Local Building Codes
After selecting the materials and purpose of your wall, it’s essential to review local building codes with your chosen contractor. Before you break ground, check with your city or county for building rules, as most areas have codes for wall height, drainage, and safety.
Here are some common requirements to keep in mind:
- Walls over 3 to 4 feet often require a permit.
- Taller walls may require approval from a licensed engineer.
- Drainage systems are required to prevent water buildup and pressure.
- Certain areas may have rules for walls used to support fences.
Note that building codes vary by location, so always check with your local building department before starting your project.
DIY vs. Hiring a Professional
DIY retaining walls can work for small projects and may save you some expenses. However, doing so may come with risks, including improper leveling, drainage, or support that can lead to costly issues later down the line.
If you’re working on larger walls, you will need tools, materials, and the know-how that most homeowners don’t have. Hiring a professional ensures the wall meets the code, drains properly, and holds up over time. Although it may cost more upfront, it often saves time, stress, and future repairs.
Additional Tips for Planning Your Project
Simple features like lighting, steps, or planter boxes can add visual appeal and function to your wall. However, that is an addition you can decide on later down the road. Here are a few helpful tips to keep in mind when you begin planning:
- Decide the purpose before choosing the size and material.
- Study how water flows through your yard and plan accordingly.
- Plan for any future upgrades like patios, decks, or fences.
- Don’t skip drainage — water is the top reason these walls fail.
- Talk to a seasoned contractor if you’re unsure about materials or construction details.
