At Bull Mountain Outdoor Living & Construction know how important it is to design outdoor areas that are both aesthetically pleasing and practical. For functional and decorative reasons, retaining walls are an essential component of landscaping. 

A well-designed retaining wall may accomplish several things, like stabilizing a slope, creating different garden stages, and improving the aesthetic value of your property. 

What are Retaining Walls?

Retaining walls are structural barriers or support systems designed to hold back and stabilize soil, preventing erosion, landslides, or sloped areas from collapsing. They are crucial in landscaping and civil engineering by creating terraces and level surfaces or preventing soil from encroaching onto structures or roadways. 

Depending on the project’s specific needs and aesthetic preferences, these walls are typically made from various materials, including concrete blocks, natural stone, Timber, or reinforced Concrete.

Retaining walls come in various styles, from simple, practical designs to decorative and visually appealing structures that enhance the landscape. They can be low garden borders or tall, imposing walls, depending on the height and weight of the soil they need to retain. 

Properly engineered retaining walls are crucial in ensuring that both business and residential buildings are secure, as they mitigate the effects of soil erosion and allow for the efficient use of land on sloped terrain.

Benefits of Retaining Wall

Retaining walls offer numerous advantages that can transform your outdoor space:

  • Erosion Control: Prevent soil erosion and slope destabilization.
  • Terracing: Create level, usable gardening or outdoor living spaces on sloped terrain.
  • Aesthetics: Enhance the overall look and appeal of your landscape.
  • Functional Space: Expand your outdoor living area with multi-level patios, seating areas, or gardens.
  • Property Value: Well-constructed retaining walls can increase your home’s value.

Types of Retaining Walls

A retaining wall project should not be started until it’s essential to understand the different types of retaining walls available:

Gravity Retaining Walls

  • It relies on the wall’s weight and mass to resist soil pressure.
  • Suitable for lower walls and less complex applications.
  • Materials include stone, concrete blocks, or brick.

Reinforced Retaining Walls

  • It incorporates reinforcements like steel or geogrids to withstand greater pressure.
  • It is ideal for taller walls and challenging soil conditions.
  • Materials include concrete blocks, poured Concrete, or Timber.

Cantilever Retaining Walls

  • Features a horizontal footing and a vertical wall that extends into the retained soil.
  • Suitable for medium to high retaining walls.
  • Often constructed using reinforced Concrete.

Anchored Walls

  • Anchored retaining walls are reinforced with cables or stays that are anchored into the soil or rock behind the wall. This design is suitable for taller walls and areas with heavy loads.

Segmental Retaining Walls (SRWs)

  • SRWs are made from modular, interlocking concrete blocks. They are versatile, easy to install, and come in various textures and colors, making them a popular choice for landscaping projects.

Timber Retaining Walls

  • Timber walls provide a natural and rustic appearance. They are suitable for lower walls and are often used in landscaping projects. Treated timber is commonly used to resist decay and insects.

Gabion Walls

  • Gabion walls are constructed by filling wire baskets with rocks or other materials. They provide a textured and permeable surface, allowing for good drainage. Gabion walls are often used in contemporary and industrial designs.

Counterfort Walls

  • Counterfort retaining walls have thin vertical slabs (counterforts) at regular intervals along the backside of the wall. These are connected to the base slab and the wall face to provide additional support, making them suitable for taller walls.

Sheet Pile Walls

  • Sheet pile retaining walls are made of steel, vinyl, or wood planks that are driven into the ground. They are commonly used in waterfront areas and locations with limited space.

Natural Stone Walls

  • Natural stone retaining walls provide a timeless and organic look. Stones can be stacked or mortared together, offering a durable and aesthetically pleasing solution.

Modular Block Walls

  • Similar to segmental retaining walls, modular block walls use large pre-cast concrete blocks that interlock. They are known for ease of installation and can be used in various landscaping applications.

Boulder Walls

  • Boulder retaining walls use large, natural boulders or rocks to create a stacked wall. This style provides a rugged and natural appearance, often used in landscaping to mimic natural rock formations.

Green or Living Walls

  • These walls incorporate vegetation into the retaining structure. They provide an eco-friendly and visually appealing solution, promoting sustainability and biodiversity.

When choosing a retaining wall style, consider factors such as the wall’s height, the type of soil, drainage requirements, and the overall aesthetic you want to achieve in your landscaping or construction project. Consulting with a professional can help ensure the chosen style is suitable for your specific needs and site conditions.

Choosing the Right Retaining Wall

Assess Your Needs

Before selecting a retaining wall, consider your specific requirements:

  • Function: Determine the primary purpose of the retaining wall (e.g., erosion control, terracing, aesthetics).
  • Height and Length: Take precise measurements of the wall required to meet your goals.
  • Style: Consider the overall design and aesthetics that align with your outdoor vision.
  • Budget: Establish a budget based on your needs and material preferences.

Material Selection

One of the most important factors in the aesthetics, durability, and maintenance of your retaining wall:

Natural Stone

  • Offers a timeless and rustic look.
  • Unique variations in color and texture.
  • It can be more expensive but adds lasting value.

Concrete Blocks

  • These are versatile and come in a rainbow of hues, sizes, and forms. 
  • Interlocking design provides stability.
  • Excellent for retaining walls of different heights.

Poured Concrete

  • Strong and durable, suitable for taller walls.
  • Customizable with various textures and finishes.
  • Requires proper installation and reinforcement for stability.

Timber

  • Ideal for a natural and rustic aesthetic.
  • Commonly used for smaller retaining walls and garden beds.
  • Requires sealing and regular maintenance to prevent rot.

Design and Aesthetics

Make a retaining wall that complements your yard and preferences:

  • Slope: Consider the slope of the terrain and whether terracing is necessary.
  • Curves: Add curves or angles to the wall for visual interest.
  • Drainage: A well-thought-out drainage system can help keep water buildup behind the wall.
  • Plantings: Incorporate landscaping elements like shrubs, trees, and flower beds to soften the wall’s look.

Cost Considerations

Budget Planning

Consider your needs carefully while establishing a budget, materials, and desired wall height. Consider the long-term costs of maintenance and additional features when making your decision.

Factors Affecting Costs

How much anything ends up costing depends on a number of your retaining wall projects:

  • Materials: High-quality materials and custom designs may cost more upfront.
  • Height and Length: Taller and longer walls require more materials and labor.
