What is the best material for a retaining wall in Brisbane’s Southside

Retaining Wall Options for Brisbane Southside Homes and Gardens

When choosing the right retaining wall for your Brisbane Southside property, a few good options can work well in this region’s climate and soils. Each retaining wall material comes with its advantages and considerations in terms of durability, maintenance, customisation, and cost over the longer life term of the wall. 

Here, we discuss the pros and cons of Brisbane’s Southside’s most common retaining wall materials.

Concrete Sleeper Retaining Walls

Concrete sleepers have become one of Brisbane’s Southside’s most popular retaining wall solutions. Pre-cast concrete sleepers provide a long-lasting, hardy, resilient material over time. Concrete sleeper retaining walls have structural strength and are heavyweight, providing inherent stability to contain soil over decades successfully. 

Brisbane Southsiders love the easy customisability of these retaining walls too, with colour options, angled designs and smooth or textured finishes. They are also one of the most cost-effective retaining solutions over the longer lifespan of the wall.

Sandstone Retaining Walls

Brisbane Southside landscapers often gravitate towards natural sandstone for retaining walls, especially on higher-end properties, for a classic and timeless look. Sandstone has an inherent beauty and seamless look when cut and installed correctly that suits both traditional and contemporary garden designs. 

Natural sandstone’s neutral tones and textured appeal complement most landscaping and require little upkeep to retain its handsome façade over decades. Unlike artificial materials, no two sandstone retaining walls will look the same due to the uniqueness of natural rock faces.

Skillful masonry work allows retaining walls to be built as rough-hewn or finely-honed sandstone blocks, depending on the desired finish. Sandstone has excellent durability and weather resistance when properly installed by expert stonemasons. Walls over 100 years old built from local sandstone still stand across Brisbane’s heritage estates.

Timber Sleeper Retaining Walls

Timber retaining walls bring an excellent natural and organic feel to gardens that lend themselves more to native bushland, forest or farm-style properties. Hardwood timbers, like spotted gum, have a handsome look and warm feeling. Timber sleepers can be used as stand-alone or with steel posts and cross bars for extra reinforcement.

One of the key benefits of using timber retaining walls in Brisbane’s climate is the rapid installation compared with masonry solutions. Sleepers slot together relatively quickly on-site to get your new retaining solution up and running, preventing major soil erosion. They also have more flexibility for contouring along natural curves or sloped sites. 

Timber sleeper retaining walls on the Southside range from simple, inexpensive DIY garden edging projects to complex reinforced structures holding back metres of earth. However, timber retaining walls require more maintenance to maintain their attractive look and structural integrity in moist environments. 

Checking and replacing rotting timbers as needed, clearing vegetation, and treating wood against termites in Queensland is part of the upkeep requirements.

Steel Retaining Walls

Structural steel retaining walls tick the boxes for sites requiring major height and load-bearing strength. Multiple metres of soil weight put major pressure on any retaining structure. Steel sheet piling driven deep into the existing earth and then reinforced with concrete and steel rods has almost unmatched strength. Steel retaining walls are used on large infrastructure and waterside projects, holding back huge tonnages.

However, structural steel solutions work on residential sites where substantial height and soil load capability are called for. A plate and post-retaining design often combine concrete footings, steel uprights, crossbars and facing materials. The strength comes from the steel itself. However, various textured finishes like wood can be attached for an attractive look.

On tricky contours and slopes, steel gives engineers more flexibility to create retaining solutions following unique contours where gravity and loading need to be offset cleverly. Steel systems may not suit every property but provide reliable solutions for substantial retaining requirements. They come with a higher price tag partly offset by requiring low maintenance over decades of service.
