Gabion Retaining Walls

  • March 31, 2025
Durable and Eco-Friendly Gabion Retaining Walls Gabion retaining walls, often called rock cages, use stone-filled steel baskets to create strong and long-lasting structures. Because of their permeable design, water flows freely through the wall. This reduces pressure, prevents damage, and makes gabions more reliable than timber walls. In addition, every basket is hot-dip galvanised, ensuring maximum protection against rust and corrosion. As a result, gabion cages work well for domestic, industrial, and commercial projects across Bacchus Marsh, Geelong, Ballarat, Gisborne, and Western Victoria. Property owners choose gabion walls because they are both durable and eco-friendly. They combine natural stone with engineered strength, which creates a solution that looks great and performs well. For this reason, gabions are increasingly popular in residential gardens, commercial landscapes, and public spaces throughout the region. Another key advantage is their adaptability. Gabions can stabilise steep slopes, control erosion, and improve drainage on challenging sites. At the same time, they can enhance urban areas as artistic landscape features or protect coastlines from water damage. By blending strength, sustainability, and style, gabion retaining walls offer a practical and visually striking solution. They are the perfect choice for managing soil, improving drainage, and transforming outdoor spaces in Bacchus Marsh, Geelong, Ballarat, Gisborne, and across Western Victoria. What are Gabion Retaining Walls? Gabion retaining walls use strong steel cages filled with stone to create a durable and natural-looking structure. Many people call them rock cages. Because of their permeable design, water flows through easily, which reduces pressure and helps prevent soil erosion. Unlike timber walls, gabions resist corrosion since every cage is hot-dip galvanised for long-lasting protection. These walls are not only strong but also eco-friendly and versatile. You’ll find them in residential gardens, commercial landscapes, public spaces, and even erosion control projects. Their natural look blends seamlessly with both modern and rustic designs. Across Bacchus Marsh, Geelong, Ballarat, Gisborne, and Western Victoria, property owners choose gabion walls because they provide effective drainage and visual appeal at the same time. Whether you want to stabilise a steep slope, create garden terraces, or add a unique feature to your landscape, gabion retaining walls deliver a practical and stylish solution that combines strength with natural beauty. Benefits of Gabion Retaining Walls Gabion retaining walls provide a range of practical and aesthetic benefits for properties in Bacchus Marsh, Geelong, Ballarat, Gisborne, and across Western Victoria. Durability That Lasts – Built with hot-dip galvanised steel cages filled with stone, gabions withstand heavy loads and tough weather. Unlike timber, they resist rot and corrosion. Eco-Friendly Design – Using natural stone makes gabions environmentally conscious. Their structure also encourages native plants to grow around them, adding to their green appeal. Superior Drainage – Because of their permeable design, gabion walls let water pass through. This reduces pressure behind the wall and lowers the risk of damage. Versatile Applications – Gabions adapt easily to different shapes, slopes, and terrains. You’ll see them in gardens, public spaces, coastal areas, and even large-scale commercial projects. Low Maintenance – Once installed, gabion walls require little upkeep. The stone settles naturally over time, which actually strengthens the structure. Strong Visual Impact – Gabions create a natural, textured look that works well in both rustic and modern landscaping. In short, gabion retaining walls combine strength, sustainability, and style.

Timber sleeper retaining wall built on sloped site in Geelong for erosion control and landscaping

Timber Sleeper Retaining Walls

  • March 31, 2025
Timber sleeper retaining walls are a perfect choice for creating a natural, rustic look in both urban and rural settings. Ideal for garden terraces, landscape borders, and erosion control, these walls blend seamlessly with natural surroundings and are a popular choice for parks, private gardens, and natural-themed commercial landscapes. What is a Timber Retaining Walls? Timber sleeper retaining walls are constructed using wooden beams or sleepers, arranged horizontally or vertically to retain soil. These walls are favoured for their natural appearance and ability to create a warm, inviting ambiance. The choice of timber and its treatment is key to ensuring the longevity and durability of the wall. Benefits of Timber Retaining Walls The aesthetic appeal of timber walls is one of their biggest advantages, offering a traditional and natural feel. They are also relatively easy to install and can be more cost-effective than other types of retaining walls. When treated properly, timber walls can resist decay and pests, making them a durable choice for many landscapes. Why Choose Us? At Outwest Retaining Wall, we specialize in crafting timber sleeper retaining walls that are not only visually appealing but also structurally sound. Our expertise in selecting the right kind of timber which is treated to withstand Australian weather conditions sets us apart. We focus on delivering walls that are both beautiful and built to last, reflecting our commitment to quality and sustainability. What is a Cantilevered Post wall? In simple terms, a cantilever post type of retaining wall is like a structural fence that holds back earth. The design principle is a cantilever post, the post is normally a steel column as specified by an engineer for permitted walls and is encased in concrete or driven into the ground. The type of soil will ultimately determine the diameter and depth of hole required for the posts. A general rule of thumb is the post goes into the ground 1.2 times the distance that the wall is above the ground. For example, consider a wall height from the ground up of 1m, the hole should be drilled to a depth of 1.2m. When concreted into the ground the post should have 100mm clearance from the bottom of the steel to the base of the hole meaning the amount of steel in the ground will be 1.1m, the amount out of the ground will be 1m, therefore the total steel length required is 2.1m. What is the lifespan of the steel posts? The steel post sections are generally hot dipped galvanised to prevent corrosion. The lifespan of hot dipped galvanised post is typically between 40-60 years. When designing the walls we have found that some people like to have their steel poles a different colour to compliment the surrounding areas. In this instance we recommend that the posts are painted using a resin-based paint system. This approach will ensure suitable protection of the steel from corrosion which will result in not only an aesthetically pleasing look but a longer lifespan.

This approach will ensure suitable protection of the steel from corrosion which will result in not only an aesthetically pleasing look but a longer lifespan. What are Timber Sleepers? Timber sleeper panels are structural panels that fill the space between the steel posts. These panels need to be structurally sound as they must take the load and resist bending due to the ground loadings coming from the rear of the wall. The timber sleepers are treated to CAA, H4 level making them suitable for retaining wall application. The benefits of timber sleepers are their natural rustic look and if they have been treated to the correct standard, they are resistant to the elements and breakdown from pests such as termites. When comparing to the concrete sleepers they are a cheaper alternative but do not last as long. Do I need the retaining wall Designed and Engineered? For any wall running along the boundary or over 1m Victorian Builders Authority law dictates that the retaining wall must be permitted and engineered. We engage structural engineers and surveyors to ensure that all our work is compliant. The following illustrates the sizing and specifications of a typical wall design. 200mm x 75mm timber sleepers can be a direct replacement for the 200mm x 75mm concrete sleepers. Why choose us for your Retaining Wall Project? Outwest Retaining Wall’s expertise in constructing concrete sleeper retaining walls is unmatched in Melbourne. We have over 40 years of construction experience and over 20 years building retaining walls to offer designs that are not only structurally sound but also aesthetically pleasing.

Widely used in both commercial and residential settings, these walls are perfect for supporting terraced gardens, creating boundary walls, and providing sturdy foundations for infrastructural developments. What is a Concrete Sleeper Retaining Wall? Concrete sleeper walls are composed of reinforced concrete panels that resemble traditional wooden sleepers. Their strength and durability make them a popular choice for long-lasting soil retention. These walls can be designed to complement various architectural styles, offering both practicality and aesthetic appeal. Benefits of Concrete Sleeper Retaining Walls The primary advantage of concrete sleeper walls lies in their exceptional durability and minimal maintenance requirements. They are resistant to rot, pests, and fire, making them a safe and reliable choice.

What is the lifespan of the steel posts? The steel post sections are generally hot dipped galvanised to prevent corrosion. Galvanising offers a modern-style wall boasting a lifespan of 40-60 years. When the post is being encased in concrete no protection is required. If a different colour is required to better match the design and surrounding areas, we recommend that the posts are painted using a resin-based paint system. This approach will ensure suitable protection of the steel from corrosion which will result in not only an aesthetically pleasing look but a longer lifespan.

Construction

  • March 28, 2025
What is a Retaining Wall & How are they Constructed? A retaining wall is a structure built to support and hold back soil or rock from an area or structure. In addition to the primary function, retaining walls can create usable outdoor space, stabilize slopes, prevent erosion, create contrast to the landscaped areas. Smaller retaining walls are used to create garden beds, support concrete slabs around the house or shed or simply to for edging around the garden. Cantilever retaining walls are perhaps the most common type of retaining wall, they are a freestanding structure without lateral support. They are supported by a footing and rise above the grade on one side to retain a higher-level grade on the other side. These walls are designed to withstand lateral pressure generated from ground behind the wall. Retaining Wall Process When it comes to retaining wall work around the home, sometimes it can be difficult to know when you can do it yourself and when you need to call in a professional concrete retaining wall installer. A retaining wall’s footing, steel selection, sleeper width, elevation and whether it requires a geogrid or other reinforcement will determine the type of retaining wall construction best suited for your project. A structural engineer is engaged to determine the correct hole depths, steel thickness/length and sleeper thickness/length. Consider your retaining wall engineering drawings as the build plan they outline all the attributes of the wall design from maximum height, sleeper span, steel size and grade to foundation depth and diameter. Small retaining walls and concrete sleeper garden edging that do not exceed 1m or more in height do not require a permit or engineering. Construction of Retaining Wall Constructing a wall on or near site boundaries where there are additional precautions that need to be taken, and/or building to exceed 1m or more in height will require careful planning and almost certainly a permit which will involve a surveyor coming on site to inspect your foundations and the wall during and at the completion of the build phase. Construction is completed in a sequence usually outline on the engineering, it can differ depending on the site elevation and wall proximity to the boundary lines. Benching the area to make space for the retaining wall is the first step on completing this step it is sometimes necessary to implement some protection works to ensure the ground is stable throughout the process and that the boundary fence can’t fall over. The site is stabilised by shoring of the ground behind the wall either by batter or it is prepared for a hit and miss sequence to be used.  Foundations are drilled to the correct diameter and depth, cleaned and inspected. Retaining wall steel is inserted into the holes by hand or excavator and held suspended in the desired position 100mm -150mm from the bottom of the hole prior to concrete being poured into the hole. Give the foundations 2-3 days to dry and the wall can be assembled and backfilled.
