When it comes to landscaping and construction, few structures are as essential as retaining walls. These practical features play a critical role in shaping the land around your property. Whether you’re dealing with uneven ground, steep slopes, or complex drainage issues, retaining walls are a key component in transforming your outdoor space.
In this blog, we’ll explore what retaining walls are, how they function, and the different types available. If you’re considering adding a retaining wall to your property, you’re in the right place. We will break down everything you need to know before you get started.
A retaining wall is a structure designed to hold back earth or soil. They can also create functional terraces or level areas in challenging landscapes. While retaining walls are primarily used for practical purposes, they also serve as an effective aesthetic feature in landscaping. A well-designed retaining wall can transform an uneven or unkempt yard into an elegant and functional outdoor space.
Gravity walls rely on their weight to resist the pressure of the soil behind them. They are made from dense materials such as stone, concrete, or brick and do not require additional reinforcement. Gravity walls are ideal for short walls (usually less than four feet in height) and can be constructed quickly and affordably. They work well in gardens or small backyard projects where significant height is not needed.
Cantilever walls use leverage to resist the pressure exerted by the soil. These walls are designed in an “L” shape, with the base of the wall extending beneath the soil to add stability. Cantilever walls are typically made from concrete and are used for taller retaining walls. These walls are often found in commercial or industrial applications due to their ability to support large volumes of soil.
Anchored walls are reinforced with anchors that extend deep into the ground, providing additional support and preventing wall movement. This type of retaining wall is suitable for areas with unstable soil conditions or when you need to retain a large amount of earth. Anchored walls are often used for high walls in commercial and residential applications.
Piled retaining walls are installed deep into the ground, with most of the wall buried to provide support. These walls are ideal for narrow spaces or areas where surface space is limited. Piled walls are commonly made from steel, concrete, or timber and can withstand significant pressure. They are often used in areas where deep soil penetration is required.
Gabion walls are made from wire mesh baskets filled with rocks or other durable materials such as gravel, recycled concrete, sandstone, limestone, clay bricks, or granite. These materials provide excellent support and long-term durability. Gabion walls are an ideal choice for erosion control and landscaping projects.
The materials you choose for your retaining wall will impact its strength, longevity, and visual appeal. Some common materials for constructing retaining walls include:
Concrete is a popular and versatile material used for retaining walls. It can be poured into different shapes and sizes, allowing for custom designs. Concrete walls are strong and long-lasting, making them a great option for large-scale projects.
Stone and brick retaining walls offer a timeless aesthetic. These materials are durable, with a lifespan of 40 to 100 years. Stone walls are often used for their natural look, while brick provides a more formal appearance. Both options require skilled labour for construction and they add significant value to your property.
Wood is a more affordable option for retaining walls, but it’s not as durable as concrete or stone. Wooden retaining walls are suitable for low walls and are often used in residential gardens or landscape features. Proper waterproofing and maintenance are crucial to ensure the longevity of wood walls.
Steel retaining walls are lightweight yet strong, making them ideal for narrow spaces or modern designs. Steel is often used in conjunction with other materials like timber or stone for added strength and visual appeal. While steel can be resistant to corrosion, it’s important to ensure that the material is properly treated to withstand exposure to moisture.
Retaining walls are a valuable addition to any property, offering both practical benefits and aesthetic appeal. Whether you’re dealing with erosion, slope stabilisation, or simply want to improve your landscape, retaining walls provide a durable and versatile solution.
