Brick for retaining wall: 3 Essential Tips

More Than Just a Wall

Brick for retaining wall projects offer a perfect blend of timeless beauty and structural strength for sloped properties. Whether for erosion control, creating usable outdoor space, or adding classic appeal, brick is a versatile and durable material.

Top brick options for retaining walls:

• Clay bricks – Traditional choice with excellent weather resistance
• Engineering bricks – High-strength option for structural walls over 4 feet
• Concrete bricks – Cost-effective alternative with consistent sizing
• Reclaimed bricks – Eco-friendly choice with unique character and patina

Success depends on proper planning, drainage, and professional installation. Most residential brick walls under 4 feet don’t require an engineer, but always check local codes. Inadequate drainage is the primary cause of retaining wall failure, making subsurface drainage with perforated pipes and gravel essential.

Cost typically ranges from $30-$110 per square foot based on internet averages (not actual McLeod Landscaping quotes), depending on wall height, soil conditions, and design complexity.

Why Use Brick for a Retaining Wall?

Choosing the right material for a retaining wall can feel overwhelming. With three decades of experience building walls throughout the Merrimack Valley, I can attest that brick for retaining wall projects consistently deliver long-term benefits.

First, consider aesthetics. Brick has a timeless appeal that complements any home style, from a colonial in Concord to a modern house in Burlington. Its warm tones and natural textures turn a functional structure into a genuine landscape feature.

Brick’s design flexibility is remarkable. Unlike rigid materials, it allows for gentle curves, decorative columns, or integrated steps. We can create intricate patterns and mix colors to achieve your desired look.

Let’s talk durability. Properly built brick walls can last 50 to 100+ years. They withstand New England’s harsh weather, from freezing winters to humid summers, and I’ve seen brick walls from the 1920s still standing strong.

This longevity increases property value. A well-built brick retaining wall is a permanent asset with timeless appeal, making it a sound investment that pays dividends for years.

Here’s how brick for retaining wall construction compares to other materials we work with:

Please note: The cost ranges provided are average costs based on internet data for materials and installation and are not actual quotes from McLeod Landscaping. Actual project costs can vary significantly based on design complexity, site conditions, material selection, and local labor rates.

What truly sets brick apart is how it ages gracefully. While other materials can look dated, brick develops a natural patina that only adds to its charm over time.

Key Considerations Before You Build

Planning a successful brick for retaining wall project requires careful preparation. The difference between a wall that lasts for decades and one that fails often comes down to what happens before the first brick is laid.

Planning Your Retaining Wall Design

When designing a brick for retaining wall, we start by defining the space’s purpose. This shapes all subsequent decisions.

• Shape: Straight walls create clean, formal lines, while curves can soften harsh angles and create natural, flowing transitions. Brick’s flexibility is ideal for creating gentle, sweeping curves.
• Size: The wall’s height and length determine material needs, construction methods, and engineering requirements, defining the project’s scope and complexity.
• Features: We can incorporate features like integrated steps for seamless transitions, decorative columns for architectural interest, and coping stones or caps for a finished look that also protects the wall.
• Terraced Walls: For steep slopes, terraced walls are an excellent solution. Creating multiple shorter walls is structurally sound and provides flat areas for gardens or patios, a technique we’ve used to transform hillsides for clients in Chelmsford.

Understanding Legal and Engineering Needs

Addressing permits and engineering upfront saves future headaches and money.

Building permits and local codes vary by town. Generally, walls over 3-4 feet require permits and engineering, but local regulations are always final. We always check with the local building department and call 811 to locate underground utilities before starting.

For brick for retaining wall projects over 3-4 feet tall, or those supporting extra loads (surcharges) like driveways, an engineer is usually required by law. Their expertise prevents costly failures by assessing soil conditions, calculating soil pressure, and designing the necessary footings and reinforcement to ensure long-term structural integrity.

Even for shorter walls, professional experience is key. Our 30+ years in the Merrimack Valley helps us identify potential issues early.

Choosing the Right Type of Brick for a Retaining Wall

Each type of brick has its own strengths and ideal uses.

• Clay bricks are the traditional choice, offering exceptional weather resistance and a classic look. They develop character over time and can last a century or more.
• Concrete bricks provide versatility and consistency. They can mimic various styles, and their precise dimensions can simplify installation.
• Engineering bricks are a high-density, low-porosity option built for strength. They are the best choice for maximum structural integrity, especially for taller walls or in harsh conditions.
• Reclaimed bricks, salvaged from old buildings, offer a unique patina and an eco-friendly option, perfect for historic areas like Carlisle.

Color and texture selection brings your vision to life. Smooth finishes create modern lines, while textured surfaces add depth. The key is matching the brick to your project’s needs, considering wall height, weather, and style. A well-chosen brick makes your wall a lasting investment.

Construction Essentials: Building a Wall That Lasts

The difference between a wall that lasts five years and one that lasts fifty often comes down to construction essentials. The real magic is in the foundation, structural choices, and behind-the-scenes details.

Mortar and Joint Finishes

The right mortar is crucial for a brick for retaining wall. It provides strength, acts as a water barrier, and helps the wall withstand soil pressure. We typically use high-strength Type S mortar for structural applications and Type N mortar for lighter-duty walls. The joint finish affects both appearance and water-shedding ability.

• Flush joints, where mortar is even with the brick face, create a clean look and are excellent for water management.
• Raked joints create deep shadow lines but can collect water, so they must be paired with an excellent drainage system.
• Weeping joints, where mortar protrudes slightly, create a rustic look ideal for reclaimed bricks or matching older brickwork.

Core Construction Methods for a Brick Retaining Wall

The core construction method is key to a wall’s structural integrity and cost-effectiveness.

• Solid brick construction is the traditional method, building the entire wall thickness from brick. While very strong, it requires more material and skilled labor.
• Cavity wall construction involves two parallel brick walls with a gap between them. This cavity can be filled with reinforced concrete for immense strength while maintaining a brick appearance.
• Block core wall with brick veneer is the method we often recommend. It uses concrete masonry units (CMUs) for the structural core, which can be reinforced for exceptional strength. A brick veneer is then applied to the face. This approach is more budget-friendly and offers great aesthetic appeal.

The Critical Role of Drainage

If I had to pick the single most important factor for brick for retaining wall longevity, it would be drainage. Poor drainage is the number one cause of retaining wall failure. Saturated soil creates immense hydrostatic pressure behind a wall, and without proper drainage, this pressure can cause it to fail.

A proper drainage system includes:

• A perforated drainage pipe at the wall’s base to collect water, wrapped in filter fabric to prevent clogging.
• Clean, coarse gravel surrounding the pipe and extending up the wall. This free-draining material prevents water pressure from building.
• Weep holes in the wall’s base to act as pressure relief valves, allowing collected water to escape.
• Proper grading of the soil above the wall to direct surface water away from the structure.

When we implement these drainage essentials properly, your brick for retaining wall will have the best possible chance of serving your property beautifully for decades to come.

Frequently Asked Questions about Brick Retaining Walls

Over the years, I’ve had countless conversations with homeowners throughout the Merrimack Valley about brick for retaining wall projects. Here are the answers to the most common questions.

How high can a brick retaining wall be without an engineer?

While avoiding extra expense is understandable, safety is paramount. The general rule is that residential walls under 3 to 4 feet (1 to 1.2 meters) often don’t require an engineer, assuming good soil and no heavy loads (surcharges) above.

However, local codes are king. Requirements vary by town, so what’s allowed in Tewksbury may differ from Wilmington. We always check with your local building department first. For any brick for retaining wall over 4 feet, or for walls with challenging conditions like steep slopes or poor soil, an engineer is typically required by law. Their expertise in structural integrity is essential for analyzing soil pressure, determining foundation depth, specifying reinforcement, and designing effective drainage.

How much does a brick retaining wall cost?

Based on internet data for materials and installation, a brick for retaining wall project typically costs between $30 to $110 per square foot.

Important note: These are average industry costs based on internet research and definitely not actual quotes from McLeod Landscaping. Every project is unique, and we always provide detailed, custom estimates after seeing your specific site and understanding your vision.

Many factors influence the final cost:

• Wall height and length are major drivers.
• The type of brick selected affects the price.
• Site conditions, such as rocky soil or limited access, can impact the budget.
• Design complexity plays a role; curves, steps, and columns require more labor.
• Behind-the-scenes costs include the essential drainage system and any professional fees for permits or engineering.

The best approach is a detailed on-site consultation to get a realistic estimate for your specific project.

What is the best way to maintain a brick retaining wall?

A little ongoing maintenance will keep your wall in great condition for decades.

• Regular inspection is key. Twice a year, check for large, horizontal, or stair-step cracks, or any bulging or leaning. These are serious red flags that require immediate professional attention.
• Clean efflorescence, a white, chalky deposit, with a stiff brush and water. It’s common and usually harmless.
• Keep weep holes at the wall’s base clear of debris to allow water to escape and prevent pressure buildup.
• Monitor surface drainage to ensure water continues to flow away from the wall.
