Innovative Retaining Wall Designs Used in Modern Construction

Retaining walls are integral to modern construction. They are used to create level sites on sloped terrain and to prevent soil erosion. There are many types of retaining walls, each with advantages and disadvantages. This blog post will explore five of the most popular retaining wall designs used in modern construction.

Buttressed retaining wall

A buttressed retaining wall is a wall that has been reinforced with a series of buttresses or vertical supports. These buttresses help support the earth’s weight behind the wall and prevent it from collapsing. Buttressed retaining wall systems are often used in construction projects with insufficient space for a cantilever wall. In addition to providing extra support, buttresses can also help increase the wall’s overall strength. However, designing an effective buttressed wall can be a challenge, as the placement of the buttresses must be carefully considered to provide maximum support.

Reinforced soil retaining wall

Reinforced soil retaining wall systems are earth retention systems that use facial panels or wire mesh to support a sloping soil mass. Geogrids are placed horizontally within the soil to provide additional reinforcement. This system is often used when it is important to minimise soil movements, such as on slopes or embankments. They are relatively easy to install and can be designed to accommodate a variety of site conditions. Reinforced soil retaining wall systems are typically more cost-effective than other earth retention systems.

Green retaining wall

Green retaining walls are an effective way to stabilise gentle slopes. A geocellular structure, such as a series of honeycomb cells, can be embedded into the slope’s surface to support and prevent erosion. The cells can then be filled with soil and planted with a variety of vegetation, which will help to hold the soil in place and further reduce the risk of erosion. In addition to their stabilising effect, green retaining walls can also improve the aesthetic appeal of a property and provide a natural habitat for wildlife.

Barrette retaining wall

Barrettes offer incredible load-bearing strength, making them ideal for retaining walls or other structures supporting substantial weight. These elements are typically constructed from concrete columns arranged in a rectangular form with a long axis designed to hold back pressure and protect against collapse.

Mechanically stabilised earth wall

MSE walls are a practical and efficient choice for civil engineering projects due to the simplicity of their construction process. These reinforced structures can easily tolerate some differential movement through soil nailing while retaining an infilled wall face with granular soil in the backfill behind it. Such innovative design contributes towards more sustainable practices that reduce cost, time spent on site and labour intensity, making them great resource-saving solutions.

Final thoughts

Ultimately, selecting a suitable retaining wall design for any project will depend on the specific requirements and conditions of that particular site. Understanding the advantages and disadvantages of each type of wall system makes it possible to choose a design that meets the project’s needs while maximising performance and minimising cost. In doing so, engineers can be sure to provide clients with a reliable and cost-effective solution that remains durable for many years.
