Retaining Wall Materials

Retaining walls play a vital role in landscaping by offering structural support to prevent erosion and hold back soil.

Concrete sleepers are precast concrete blocks that are used to retaining wall concrete sleepers. They are known for their strength, durability, and versatility, and can come in a variety of sizes, colors, textures, and finishes. Concrete sleepers are reinforced with steel bars, making them a good choice for taller retaining walls and more demanding engineering applications. They can also last a lifetime, unlike timber sleepers that need to be pretreated and only last a couple of decades.

Beyond their practical function, they add charm to outdoor spaces. When choosing the perfect material for your retaining wall, factors like cost, durability, and maintenance are key.

Join us in this article as we explore different common retaining wall materials, evaluating their cost-effectiveness and durability to empower you in making informed decisions for your landscaping projects. Let's dive in!

Understanding Retaining Wall Materials

Before delving into the specifics of retaining wall materials, let's outline the primary types of materials commonly used for constructing retaining walls:


Known for its strength and versatility, concrete is a popular choice for retaining walls. It can be poured into molds or formed into blocks for added customization. However, concrete can be costly and may require skilled labor for installation.


Natural stone is a classic choice for retaining walls, offering a timeless look and unparalleled durability. It can be found in various types like granite, limestone, or bluestone. While it may come with a higher upfront cost, its longevity makes it a worthwhile investment.


Brick is another popular material for retaining walls due to its aesthetic appeal and affordability. It comes in various colors and textures and requires minimal maintenance. However, brick may not be as strong as other materials and could crack under pressure.


Wooden retaining walls offer a rustic charm to outdoor spaces but are not the most durable option. They may also require regular maintenance such as sealing and staining to protect against rot and pests.


Gabion walls are constructed using wire cages filled with rocks or stones, creating a unique and modern look for retaining walls. They are also very strong and can withstand pressure from soil and water behind them. However, they may require regular maintenance to prevent debris from getting stuck in between the rocks.


Boulder retaining walls offer a natural and rugged appearance to outdoor spaces. They are usually made of large boulders stacked together without any mortar, creating a rustic and organic look. However, boulders can be difficult to work with and may require heavy machinery for installation.


Timber is a popular choice for retaining walls because of its natural beauty and versatility. It can be easily cut into different shapes and sizes, making it suitable for various landscape designs. However, timber may not be as durable as other materials and may require regular maintenance to prevent

Cost Analysis

When it comes to the cost of materials for retaining walls, there are a few factors to consider. The size and height of the wall will affect the amount of material needed, as well as any additional features such as curves or corners.

Retaining Walls Concrete

Concrete retaining walls are known for their affordability and durability. The cost of concrete varies depending on factors such as the type of mix used, labor costs, and site accessibility. On average, expect to pay between $20 to $30 per square foot for professionally installed concrete retaining walls.

Retaining Walls Stone

A Retaining wall stone, particularly those constructed with commercial limestone retaining walls, offers durability and aesthetic appeal. However, they tend to be more expensive than concrete or wood. The cost of stone retaining walls can range from $30 to $40 per square foot, depending on the type of stone and complexity of the design.

Retaining Walls Wood

Wood retaining walls are generally less expensive upfront compared to concrete or stone. However, they may require more frequent maintenance, such as sealing or staining, to prolong their lifespan. The cost of wood retaining walls typically ranges from $15 to $25 per square foot, making them a budget-friendly option for landscaping projects.

Retaining Wall Bricks

Retaining wall brickswalls strike a balance between affordability and durability. While they may cost slightly more than wood, they offer longevity and require minimal maintenance. Expect to pay between $25 to $35 per square foot for professionally installed brick retaining walls.

Retaining Walls Composite

Composite retaining walls are relatively new to the market but offer several advantages, including durability and sustainability. They may cost more upfront than wood. But, composites need little maintenance and can last for decades. Prices for composite retaining walls vary but typically fall within the range of $25 to $35 per square foot.

Durability Assessment

When considering the cost of a retaining wall, it's important to also factor in its durability.

Concrete Retaining Walls

Concrete retaining walls are renowned for their strength and resilience against the elements. Concrete walls can withstand high pressure from soil and water. They can do this when properly reinforced and installed. This makes them suitable for many landscape uses.

Stone Retaining Walls

Stone retaining walls, especially those constructed with commercial limestone, boast exceptional durability. Limestone is natural. It can endure weathering and erosion over time. This ensures long-term stability for retaining structures.

Wood Retaining Walls

Wood retaining walls look nice. But, they can rot, get insects, and warp if not well maintained. Treated lumber extends life. But, wood walls need upkeep to stop decay and problems.

Brick Retaining Walls

Brick retaining walls are known for their durability and resistance to weathering. Fired clay bricks can handle moisture and temperature changes. They provide a sturdy barrier against soil erosion for many years.

Composite Retaining Walls

Composite materials offer superior durability compared to traditional wood options. Composite retaining walls are made from a blend of recycled plastics and wood fibers. They resist rot, decay, and insect damage. This ensures longevity without the need for frequent maintenance.

Making an Informed Choice

When it comes to selecting the right material for your retaining wall, it's essential to weigh the cost and durability factors carefully. You can opt for the low cost of wood, the timeless elegance of stone, or the durability of composites. Each material has its unique benefits and things to consider.

By understanding the costs and durability of common retaining wall materials, you can make an informed decision. It will fit your landscaping needs and budget well.
