  • Curved retaining walls: Soften the look of your landscape with gentle curves and flowing lines.
  • Tiered retaining walls with integrated stairs: Connect different levels of your garden with stylish and functional stairs built into your retaining wall.
  • Retaining walls with built-in seating or planters: For a multi-functional feature, make the most of your retaining wall by incorporating seating areas or planter boxes.

  • Small retaining wall: Ideal for gardening contexts, a small retaining wall is cost-effective and perfect for flat areas. It can be used to plant flowers around trees while keeping expenses down.
  • Stacked stone walls: A popular choice for small retaining walls, stacked stone walls offer aesthetic appeal and ease of installation without the need for cement or mortar. They are also great for creating vertical gardens with ample nooks for plants.
  • Wall stones: Wall stones provide both aesthetic and functional advantages in landscaping. They offer various options, including concrete and bricks, for creating visually appealing and structurally sound walls that enhance outdoor spaces while preventing soil erosion.

Planning and Building Considerations

Before embarking on your retaining wall project, it’s essential to understand the planning and building requirements in your area. 

In Australia, retaining walls over a certain height (usually 1 metre) require council approval. Before starting construction, it’s crucial to check with your local council for specific regulations and obtain any necessary permits.

Proper drainage is another critical factor in retaining wall design and construction. Ensure your wall incorporates adequate drainage solutions, such as weep holes or agricultural pipes, to prevent water pressure build-up and potential wall failure.

When to Bring in the Experts

When it comes to building your retaining wall, you have the option to either hire a professional landscaper contractor or take on a DIY approach. A DIY retaining wall can be a versatile and cost-effective solution for smaller projects, offering aesthetic and functional benefits. However, it’s often best to engage a qualified professional to ensure structural integrity and longevity for larger or more complex retaining walls.

The total cost of your retaining wall project will depend on various factors, including the size of the wall, the chosen materials, site accessibility, and any additional features or landscaping elements. Remember to contact us for a free quote.

Maintenance and Longevity

Regular maintenance is key to ensure your retaining wall stands the test of time. Conduct periodic inspections to check for any signs of damage, such as cracks, bulging, or tilting. Address any issues promptly to prevent further deterioration.

Maintaining proper drainage is also crucial for the longevity of your retaining wall. Clear weep holes and drainage pipes of any debris or blockages to allow water to flow freely. Consider applying waterproofing sealants or treatments to your wall to enhance its durability and resistance to moisture damage.

  • Popular retaining wall materials include concrete sleepers, timber, stone, and brick
  • Creative retaining wall design ideas can transform your outdoor space
  • Council approval and proper drainage are essential considerations for retaining wall projects

Frequently Asked Questions

How high can I build a retaining wall without council approval? 

In most Australian states and territories, retaining walls under 1 metre in height generally don’t require council approval. However, it’s always best to check with your local council for specific regulations, as requirements may vary depending on your location and the nature of your project.

How long do retaining walls typically last? 

The lifespan of a retaining wall depends on factors such as the material used, the construction quality, and the maintenance level. On average:

  • Concrete sleeper walls can last 50+ years
  • Timber walls have a lifespan of 10-20 years
  • Stone walls can last 50-100 years or more
  • Brick walls can last 50-100 years with proper care

Can I build a retaining wall myself, or should I hire a professional?

Whether to DIY or hire a professional depends on your skills, experience, and project complexity. Confident DIYers can often tackle small, low retaining walls (under 1 metre). However, for taller walls or those with challenging site conditions, it’s recommended to engage a qualified professional to ensure safety, structural integrity, and compliance with local regulations.
