Frequently Asked Questions
What is a retaining wall and what does it do?
A retaining wall is a structure built to hold back or support soil on sloped land. It's used to prevent erosion, manage drainage, or create level ground for gardens, driveways, and building foundations. These walls are essential where elevation changes occur on a property, allowing safe and practical use of uneven terrain. Retaining walls come in various styles and materials, including concrete blocks, stone, timber, and poured concrete. Aside from their functional benefits, they also enhance the appearance of outdoor spaces. Properly designed and built retaining walls ensure long-term stability and safety, especially during heavy rainfall or when supporting heavy loads.
What types of materials are used for retaining walls?
Retaining walls can be built from a range of materials depending on the project’s style, budget, and structural needs. Common options include concrete blocks, which are durable and versatile, and natural stone for a more traditional look. Timber retaining walls are popular for their affordability and ease of installation, although they may not last as long as other materials. Concrete sleepers are another sturdy, modern choice, often used in both residential and commercial settings. The material used affects the wall’s strength, appearance, and maintenance requirements. A professional can recommend the most suitable material based on the site conditions and desired outcome.
When is a retaining wall necessary?
A retaining wall is necessary when there’s a significant change in elevation on your property, and you need to stabilise the soil or prevent erosion. They’re also used to level out areas for patios, driveways, gardens, or paths. Retaining walls help manage stormwater runoff and protect structures from shifting or collapsing ground. If your yard has slopes or you're planning a new build on uneven terrain, a retaining wall may be required for both function and compliance. In some cases, local councils may mandate retaining walls for certain developments, especially where public safety or drainage is affected by land movement.
