Retaining walls serve a crucial role in many Omaha landscapes by preventing soil erosion and managing elevation changes. Choosing the right retaining wall enhances your landscape while supporting slopes and uneven terrain.
This guide will walk you through the most common types of residential , their materials, and design considerations. Whether you are planning a small garden wall or a larger structural wall to support a slope, understanding your options will ensure your retaining wall stands the test of time.
Choosing the Right Retaining Wall for Your Property: Materials, Styles, and Designs
Different wall types are designed to handle different loads, heights, and site conditions. Knowing the basics helps you and your contractor choose the right approach for your property.
Most Common Types of Residential Retaining Walls
Gravity Retaining Walls
Gravity walls rely on their own weight to hold soil in place. They often use stone, concrete blocks, or other heavy materials and can be a great choice for shorter walls and decorative tiered gardens. Gravity walls can provide good aesthetics and strong bearing capacity in the right conditions.
MSE or Reinforced Soil Retaining Walls
Mechanically stabilized earth (MSE) walls combine facing units with layers of reinforcement, such as geogrid, to support taller walls and wider slopes. They are often used when you need to handle significant loads or height while keeping a relatively slim wall profile.
Crib Walls
Crib retaining walls are built using interlocking, hollow cells (often precast concrete or timber) that are then filled with soil or rock. They can be a good choice for steeper slopes in gardens and can be softened visually with plantings for a landscaped finish.
Cantilever Retaining Walls
Cantilever walls use a reinforced concrete base and stem to resist soil pressure and are typically used for taller, more structural applications. They are engineered for strength and can also be designed to create terraced areas or tiered garden aesthetics in the yard.
A Few Things to Think About When Planning And Choosing The Right Retaining Wall
A retaining wall isn’t your average wall. A lot is riding on mitigating the risk of supporting the slope behind it. Planning for the wall is a crucial step in avoiding wall failure.
Fortunately, you don’t need to be an engineer to plan it properly. However, if you have no idea what you’re doing, enlisting a landscaper’s services helps.
The first step in the planning process is establishing its purpose; some examples would include:
- Erosion prevention and control
- Leveling slopes
- Aesthetics
Understanding the functionality of the wall improves its stability and service life.
Once the purpose is clear, consider these site‑specific factors:
- Soil type: Clay, sand, and loam behave differently and influence drainage and wall design (height, thickness, reinforcement).
- Drainage needs: Every retaining wall must address water. Proper drainage behind the wall is crucial to relieve pressure and prevent failure.
- Local climate: Omaha’s freeze‑thaw cycles and heavy rains require walls built with appropriate materials, base prep, and drainage systems.
You do not need to be an engineer to appreciate these factors, but if you are unsure where to start, working with an experienced landscaper or retaining wall contractor can prevent costly mistakes.
Choosing The Right Retaining Wall Design for Sloped or Uneven Terrain
Since retaining walls are there to stop calamities, they require proper installation and design. Considerations must be made for potential harm relating to the structures they support.
Homeowners and landscapers have two things to consider when designing the wall and the purpose of the wall:
- Structural integrity
- Aesthetics
For the design phase, popular choices for retaining walls include curved walls, especially in heavy load-bearing installations, and stepped designs for steeper gradients.
Terracing creates a tiered garden look to the wall. Covering up colder materials like concrete as the plants bloom adds to the aesthetic.
Comparing the Pros and Cons of Different Retaining Wall Materials
There are several different types of retaining wall materials to choose from. Many homeowners choose natural stone for their retaining wall materials. Retaining walls constructed with natural stone are incredibly beautiful. They create a wonderful rustic aesthetic with a classic look to your landscape design.
Natural Stone Retaining Walls
Natural stone comes in various options to suit your budget. Building retaining walls with this material is expensive and requires professional installation.
Concrete Retaining Wall Blocks
Concrete retaining wall blocks are among the most common materials for retaining walls in residential and commercial applications. Segmental retaining walls might look cold and grey but are ideal for creating structurally sound walls in various designs.
Concrete blocks are relatively easy to install. With the ease of installation, you can create tiered garden beds in the wall to offset the concrete.
Brick Retaining Walls
Brick creates a timeless look in your retaining wall and is ideal for more traditional homes. However, installing retaining walls made with brick comes with substantial labor costs. Bricks generally fall behind natural stone and concrete blocks in terms of durability.
Wood/Timber Retaining Walls
A timber retaining wall is an affordable choice. Timber enhances the natural aesthetic of your outdoor space and is suitable for creating a rustic look.
However, wood is prone to rot. Proper drainage to prevent water from collecting behind the wood is essential. Wood requires treatment and maintenance to keep it looking great.
Budget and Cost Considerations For Your Retaining Wall Project
Your budget is a top priority when planning your retaining wall design and the materials you use to build it. Don’t over-extend yourself. This project is expensive and can run over budget by hundreds or thousands of dollars.
That is why the planning phase is so important. That’s why working with a professional landscaper is a good idea. They’ll handle:
- The survey
- Sourcing of materials
- Construction
- The logistics
- Hiring the team
So, you can imagine this isn’t a DIY project you can pull off on the weekends. You need a professional on-site to coordinate and manage the project.
Retaining Wall Maintenance for Long-Lasting Service Life
After laying the last brick in the wall, it’s time to relax – but not for too long. Your retaining wall requires some maintenance to keep it structurally sound and looking good.
Arrange seasonal inspections before and after the rainy season to prepare the wall for the weather. This allows you to see any damage it sustained during the rainy months.
A local landscape design/hardscape contractor can help you with the inspection for a minimal fee, and they’ll spot issues you might miss.
