Retaining Walls Installation

What is a Timber Retaining Wall?

A timber retaining wall is a sturdy structure built to hold back soil, prevent erosion, and create level areas in your yard or garden. It’s great for sloped areas where you want to create flat, usable spaces.

In landscaping, timber retaining walls help shape your outdoor area while keeping everything neat and secure. Treated pine, hardwood, or timber sleepers are often the materials for these walls.

Many homeowners prefer timber walls over concrete or block walls because they blend seamlessly with gardens and outdoor settings. It’s also more affordable and made from renewable resources, making it an eco-friendly choice.

Whether you’re upgrading your yard or shaping a new landscape, a timber retaining wall adds both function and charm.

What Types of Timber Retaining Walls Are Available?

There are a few main types of timber retaining walls, each with its own look and level of strength. The right choice depends on your soil type, slope, and how much support your wall needs.

• Treated Pine: A popular, budget-friendly option. H4-treated pine suits general landscaping, while H5-treated pine is better for in-ground or heavy-duty use.
• Hardwoods: Tough and long-lasting, perfect for taller or longer walls. Timbers like Spotted Gum and Silvertop naturally resist decay and pests, while recycled hardwood sleepers bring a rustic, weathered charm to your landscape.
• Round Logs: Great for a traditional, natural look and cost-effective for large areas. You can stain them or leave them raw for a more rugged feel.

Each type of timber suits Melbourne’s varied soils and slopes differently, and higher walls may need drainage and council approval.

How Long Does a Timber Retaining Wall Last?

The lifespan of a timber retaining wall depends on the type of wood, soil conditions, and how well it’s installed and maintained. On average:

• Treated Pine: Lasts around 10 to 15 years with proper care.
• Hardwood: Can last 20 to 25 years or more thanks to its natural strength.

Good drainage, quality treatment, and correct installation make a big difference. Proper maintenance and professional installation also ensure your retaining wall stays strong and looking great for many years.

How Are Timber Retaining Walls Installed?

Building a timber retaining wall takes planning and the right technique to make sure it lasts. Here’s how it’s usually done:

1. Site inspection and planning: Check soil type, slope, and wall height.
2. Excavation and drainage: Prepare the base and ensure proper water flow.
3. Post installation: Set posts deep in concrete with even spacing for strength.
4. Sleeper placement: Secure sleepers between posts for a solid structure.
5. Backfill and drainage: Add soil and gravel to keep the wall stable.

Professional installation ensures correct design, waterproofing, and compliance, especially for taller walls needing engineering approval.

How Much Does a Timber Retaining Wall Cost in Melbourne?

The cost of a timber retaining wall in Melbourne ranges from $250 to $450 per linear metre on average, depending on height, materials, and site conditions. Here’s what affects the price:

• Timber type: Treated pine is more affordable, while hardwood offers greater strength and a longer lifespan.
• Site slope and soil type: Steeper or softer ground may need extra support or deeper posts.
• Labour and equipment: Tight access or difficult terrain can increase labour costs.
• Drainage and permits: Proper drainage and council approvals may add to the total cost.

To save money, consider using treated pine in low-impact areas or keeping wall heights shorter where possible.
