Retaining Walls

If your garden looks flat and two-dimensional, or if you have a small plot, constructing retaining walls adds height and space to your property. Outdoor and General offer quality retaining walls in a range of makes, types, sizes, textures, and colours to help transform a mundane outdoor landscape to a pleasant, attractive space.

Our retaining walls are strong, attractive, and versatile, blending with a wide array of architectural styles, local microenvironments, and design concepts. Locally manufactured by industry leaders who understand the climate and environmental conditions that can affect outdoor installations.

Design applications include:

• Pool enclosures.

• Raised garden beds.

• Garden edging.

• Firepits.

• Curved walls.

• Straight walls.

• Tiered walls and terraces.

• Corners.

• Outdoor stairs.

• Stabilisation for slopes and embankments.

• Drainage channels.

These attractive retaining walls come in different textures and styles. Their rough-hewn appearance blends well with surrounding environments. Pigments are embedded in the matrix during manufacturing, resulting in long-lasting colours that add style and character to your landscape. Some retaining wall systems have separate capping units, corner blocks and top finishes. Sizes and shapes vary to suit design styles from contemporary to rustic.

Interlocking retaining wall blocks are engineered to fit together and for quick installation. Our range of retaining wall block products can generally be built to 800mm height without reinforcement. For extra strength, concrete building blocks i.e., Besser Blocks can be built as retaining walls and structural walls.

Concrete sleepers are an excellent choice for retaining walls. They are long panels with engineering design and reinforcing for simpler installation. They carry a new sophistication, refining and harmonising the look with any architectural style.

The staff at Outdoor and General can help you select appropriate retaining walls for your project. Whether you want an elegant look, a down-home, casual look or a professionally landscaped outdoor environment, our range of products built to Australian standards will surely suit your needs. We also sell cleaners and sealants that enhance the look of natural and engineered products while protecting from staining.

Create more usable space by adding retaining walls to moderate slope, retard erosion and add depth to expanses of garden areas. Here, we discuss how to enhance your property with outdoor modifications that range from simple, do-it-yourself projects to a professional landscape overhaul.
