Top Trends in Retaining Wall Design for 2024: What’s New and What’s Next

Sustainability at the Forefront: Eco-Friendly Materials and Techniques

Sustainability continues to be a major theme in landscaping, and retaining walls are no exception. The use of recycled materials such as crushed concrete, reclaimed wood, and repurposed stone is on the rise. These materials not only reduce the environmental impact but also offer unique aesthetic benefits that blend seamlessly with natural surroundings. Moreover, the integration of green walls or “living walls” into retaining structures is becoming more popular. These walls use vegetation to cover the surface, which not only beautifies the space but also contributes to biodiversity and helps with thermoregulation.

Incorporating Technology: Engineering Smarter Retaining Walls

The use of advanced engineering techniques and materials to improve the durability and functionality of retaining walls is another key trend. Geogrids, for instance, are synthetic materials used to reinforce soil and increase the stability of the wall. This technology allows for taller and more complex retaining wall structures that are both safe and visually striking. Additionally, the application of smart sensors within retaining walls to monitor moisture levels and structural integrity is starting to make headway, offering a proactive approach to maintenance and longevity.

Customisation and Personalisation: Making a Personal Statement

As more homeowners look to customise their outdoor spaces, retaining walls are increasingly viewed as an element of personal expression. Customisable options like adjustable panels, varying textures, and integrated lighting systems allow for a high degree of personalisation. These features can transform a purely functional retaining wall into a standout feature of garden design. From minimalist and sleek designs that complement modern architectural styles to rustic and rough-hewn looks that evoke a more natural feel, the possibilities are endless.

Retaining Walls as Multi-Functional Features

Beyond their traditional role in preventing soil erosion and managing sloped areas, retaining walls are being designed to serve multiple functions. Built-in seating, incorporated water features like fountains or waterfalls, and even embedded fire pits are becoming commonplace. These elements not only maximise the usability of the land but also enhance the overall enjoyment of the outdoor space, making retaining walls central to outdoor entertainment areas.

Adapting to New Zealand’s Unique Climate

In New Zealand, the choice of materials and construction techniques must also consider the local climate’s challenges, including high rainfall, occasional seismic activity, and exposure to coastal environments. Materials that are resistant to moisture and salt air, as well as construction techniques that can withstand geological movements, are particularly valuable.
