While all kinds of retaining walls are beautiful and functional, stackable retaining wall blocks are particularly useful for DIY projects and simple installations. These interlocking blocks can level slopes, retain soil and build garden features without requiring the use of mortar. These blocks, which are widely available in Australia, are as strong and aesthetically pleasing as other DIY types with the added bonus of being faster to carry out.
With our experienced approach to earthworks in Adelaide, Pinnacle Earthworks can use our expertise to build you a wall or provide retaining wall blocks for DIY projects. Our blocks are available in various faces, colours and styles to suit the aesthetic and budget of any Adelaide property.
Construction blocks have been around for a long time, with the ‘Besser Block’ being one of the most widely known examples. There are many more aesthetically appealing examples of retaining wall blocks though, and Pinnacle Earthworks has many of them. Retaining wall blocks use interlocking mechanisms to provide structural stability and build durable retaining walls and terraced gardens.
Types of retaining wall blocks
Pinnacle Earthworks offers the following kinds of retaining wall blocks:
Versawall ® blocks
Available in a range of colours from oatmeal to charcoal to sunstone, Versawall ® blocks have a modern look and groove joints for easy installation.
Boral retaining wall blocks
As Australia’s largest vertically-integrated construction material company, with an 80-year-history, Boral provides durable and sustainable wall blocks.
Standard concrete blocks
Standard concrete blocks (or Besser Blocks) are an old style of wall block but a good one, with strong fire resistance and high load-bearing structural strength.
Split-face blocks
The textured, exposed aggregate finish of split-face blocks creates a rustic look that mimics quarried stone. The result is rough but elegant and very contemporary.
Coloured blocks
Want to get creative with colours? Pinnacle Earthworks blocks allow you to customise with the right shades and tones to suit the look of your backyard.
The benefits of retaining wall blocks
Retaining wall blocks have a range of benefits both aesthetic and functional including:
Easy to install
Because retaining wall blocks don’t require mortar, they’re affordable and easy to install and particularly useful for DIY projects.
Low maintenance
Retaining walls offer a low maintenance approach to earthworks in general. Concrete blocks are particularly resistant to pests, rot and weathering, meaning less upkeep compared to timber.
Natural drainage
One of the biggest benefits of retaining walls is that they redirect drainage away from your home, reducing runoff and preventing erosion. Concrete walls are strong enough to provide a reliable source of drainage while protecting against wild weather.
Additional usable land
Retaining walls turn steep, challenging slopes into flat and productive spaces for gardens, lawns, patios, entertaining areas and other leisure spots. This raises the value of your home and enhances your enjoyment while you live in it.

Common Questions About Our Retainer Walls Services:
Retaining wall costs in Adelaide typically range from $200-400 per square meter depending on materials, height, and site conditions. Concrete sleeper retaining walls are the most cost-effective option for quality results. Contact us for a free quote specific to your project.
Concrete sleeper retaining walls are the most popular choice in Adelaide due to their durability, modern aesthetic, and cost-effectiveness. For Adelaide Hills properties, rock walls and gabion walls also work well. The best choice depends on your budget, aesthetic preference, and site conditions.
Council approval requirements depend on wall height and location. Generally, retaining walls under 1 meter may not require approval, but this varies by council. Walls over 1 meter typically need engineering certification and council approval. We can advise on requirements for your specific project, though we don’t handle council applications.
Concrete sleeper retaining walls have a lifespan of 50+ years when properly installed with adequate drainage and steel pier foundations. They’re durable, termite-resistant, and require minimal maintenance, making them an excellent long-term investment for Adelaide properties.
Yes, we specialise in Adelaide Hills retaining walls on sloped terrain. We have extensive experience with terraced walls, steep blocks, and challenging soil conditions. Proper engineering, drainage, and steel pier foundations ensure stability on slopes.
Yes, we proudly service Adelaide Hills including Mt Torrens, Inverbrackie, Woodside, Lobethal, Stirling, and surrounding areas. We understand the unique challenges of hills terrain and have built hundreds of retaining walls throughout the Adelaide Hills region.
Concrete sleepers are horizontal planks installed with steel posts, offering a modern linear appearance. Retaining wall blocks are interlocking units stacked vertically. Sleepers typically provide a cleaner look and are more popular in Adelaide, while blocks offer more design variety. Both are durable options.
Yes, proper drainage is critical for retaining wall longevity. We install ag pipe behind walls, drainage gravel, and weep holes to prevent water pressure buildup. Adelaide’s weather makes drainage essential to prevent wall failure. We can integrate retaining wall drainage with your property’s stormwater system.
A typical residential retaining wall takes 2-5 days to complete, depending on size and complexity. Larger commercial retaining walls may take 1-2 weeks. We provide a clear timeline with your quote and keep you updated throughout the installation process.
Yes, we can install fencing on top of concrete sleeper retaining walls. This is a popular “good neighbor” fencing solution in Adelaide. The retaining wall must be engineered to support the additional load of fencing, which we factor into the design.
