Sloped landscapes and shifting soil are common challenges in Metairie. Whether you’re trying to control erosion, level out your yard, or give your outdoor space a cleaner, more finished look, adding a retaining wall can be a practical and lasting solution. However, before starting construction, it is important to think carefully about the design. Even the strongest structure can fail or collapse over time without proper planning.
Don’t risk poor planning or failed construction. If you’re ready to build, trust the leading masonry contractor in Metairie for lasting results.

Important Design Elements for a Strong and Safe Retaining Structure
1. Understand the Purpose
Before anything else, it’s important to determine why the wall is needed.
- Is it to stop soil erosion?
- Hold back a slope?
- To create a raised garden bed?
- Make the yard more aesthetically pleasing?
Each purpose influences the type, size, and materials used. A wall holding back heavy soil will need proper drainage and reinforcement, while decorative garden walls may only need a few courses of bricks or blocks.
2. Know Your Soil Type
Every soil behaves differently. While clay retains moisture and expands, sandy soil drains rapidly but shifts easily. Before beginning, a soil test should be conducted because the soil conditions in Metairie can differ greatly between properties.
A local masonry contractor will factor in the soil’s behavior under pressure. For instance, expansive clay may require deeper footings or geogrid reinforcement to prevent movement over time.
3. Height and Local Regulations
In Metairie and the neighboring parishes, walls higher than a certain height (often 4 feet) may require an engineering approval or permit. Building codes exist to ensure public safety, and ignoring them can lead to costly delays or even legal action.
Even for shorter walls, hiring a professional ensures compliance with local rules while keeping the structure sound.
4. Material Selection Matters
From natural stone to concrete blocks, the material chosen affects not just appearance but also longevity, load capacity, and cost. In Louisiana’s humid climate, materials should be resistant to moisture and temperature changes.
Popular material options include
- Concrete blocks: Durable and customizable
- Natural stone: Timeless and elegant
- Brick: Traditional and great for cohesive home designs
- Segmental blocks: Interlocking systems that offer strength without mortar
A qualified masonry contractor can recommend the best fit based on aesthetics, budget, and structural needs.
5. Drainage Design Is Critical
Poor drainage is one of the most common causes of retaining wall failure. Water buildup behind the structure increases pressure and can lead to cracking or collapse.
Every wall should have:
- A gravel backfill for water flow
- Perforated drainage pipes at the base
- Weep holes to release excess moisture
In Metairie, where rain can be heavy and unpredictable, drainage isn’t optional—it’s essential.
6. Reinforcement for Stability
To securely hold back the earth, larger or load-bearing walls often require extra reinforcement. This can include:
- Geogrid: A synthetic mesh placed between soil layers for stability
- Deadman anchors: Extensions that grip the soil behind the wall
- Tie-backs or steel bars: For added strength in taller structures
Working with experienced masons ensures these elements are properly integrated into the wall’s design.
7. Consider Aesthetics and Landscaping
Curb appeal is just as important as functionality, especially if you are planning on selling your house in the future. Coordinating the wall with the overall landscape design can transform a yard from plain to premium.
Think about:
- Color coordination with your home’s exterior
- Integrated steps or seating
- Terracing for steep slopes
- Plantable wall systems for greenery

Can I build a retaining wall myself?
While DIY is possible for small walls, professional installation is strongly recommended for larger or structural walls to ensure safety and durability.
What’s the best material for retaining walls in humid areas like Louisiana?
Concrete blocks and natural stone perform well in Louisiana’s climate. They resist moisture and require minimal maintenance.
How do I know if my yard needs a retaining wall?
If your yard has uneven terrain, erosion, or soil runoff issues, a wall may be necessary to stabilize and reshape the space.
Will a retaining wall add value to my property?
Yes, well-built walls improve both functionality and curb appeal, often increasing property value.
Can poor drainage damage my wall?
Absolutely. Inadequate drainage causes water buildup and pressure, leading to cracks, bulging, or collapse. Proper design includes gravel, pipes, and fabric layers to manage water flow.
