Retaining Wall Installation

Retaining wall installation is the process of building a wall that holds back soil and creates a stable, level area. It’s commonly used for sloping blocks, garden beds, cut and fill, and to make more usable outdoor space. We offer retaining wall installation as part of our done-for-you services.

We provide retaining wall installation, including rock retaining walls, plus associated earthworks that often come with wall jobs (site cuts, levelling, spoil removal, and access prep). Rock retaining walls are a core listed service in our done-for-you range.

A rock retaining wall is a good choice when you want:

• High durability and a solid, heavy wall

• A natural look that suits most landscaping styles

• A wall that works well for new blocks and larger landscaping projects

We build rock retaining walls to suit different styles and budgets.

A brick retaining wall can suit smaller walls where you want a neat, structured look that matches the home or other masonry. Brick walls usually need good drainage and footing detail, and they can cost more in labour than rock, depending on site access. If you’re set on brick, share photos and wall dimensions and we’ll tell you what’s realistic for your site and local area.

Concrete retaining walls suit higher-load situations and cleaner, modern finishes. They often make sense when:

• The wall needs to handle higher ground pressure

• You want a straight, uniform finish

• Your site needs engineered solutions (common for taller walls)
  Concrete work often needs more planning around drainage, footings, and approvals. Talk to your local Diggermate about scope and what’s achievable on your block.

Some Diggermate locations offer a machine + wet hire combo. Availability and pricing vary by location, so please contact your local Diggermate to confirm options and get a tailored quote.

For wet hire, our national guide rate is $119 per hour with a minimum charge of 3-hour plus 1-hour travel for each job. Rates may vary by location.

Your final cost will depend on:

• Machine hire type or combo selected

• Wall length and height

• Materials (rock, blocks, concrete systems)

• Drainage requirements

• Site access and spoil removal

• Any engineering or council requirements

Most jobs depend on wall size, access, soil conditions, material deliveries, and drainage. Smaller garden walls can be done quickly, while longer or taller walls can take multiple visits. If you share wall length, height, photos, and access details, we’ll give you a realistic time estimate.

We provide experienced operators as part of wet hire services. Materials supply depends on wall type and location. For rock retaining walls, we build walls to suit different budgets and styles, and we’ll confirm supply and inclusions in your quote.

Yes. We specialise in compact equipment designed for tight access and smaller spaces, which helps on narrow side access, backyards, and constrained sites.

Yes. For wet hire, we provide operators who are trained and licensed to operate the equipment.

Before we start, you’ll get the best result if you:

• Mark the wall line (or share a sketch and photos so we can confirm it)

• Clear the work area (furniture, pots, debris)

• Confirm underground services and utilities locations

• Provide site access info (gate width, steps, slopes)

• Confirm any council or engineering requirements if your wall may trigger them (often height-related)

We cover retaining wall services through locally owned Diggermate locations across Australia and New Zealand. Service coverage varies by area, so check your nearest location for availability.

You can book online via our done-for-you services and select your local Diggermate, or contact your local Diggermate directly to discuss your project and get a quote.

We’ll usually need:

• Your suburb and site access notes

• Wall type preference (rock, block, concrete, unsure)

• Approx wall length and height

• Photos of the site (wide and close-up)

• Any known constraints (drainage issues, tight access, nearby structures)

• Your timing and any deadlines
