Creating a beautiful and functional garden often involves overcoming various landscaping challenges, including managing sloped surfaces. Retaining walls not only provides a solution to this problem but also adds aesthetic appeal to outdoor spaces. Read on to explore the different types of retaining walls suitable for gardens, helping you select the right one for your needs.

Gravity Retaining Walls

Gravity retaining walls rely on their own mass to hold back soil and are typically built from heavy materials such as stone, brick, or concrete. These walls are ideal for gardens needing minimal height adjustments and can be a DIY project for those with some construction experience. The natural appearance of stone or brick can enhance the garden's aesthetic, blending seamlessly with the surrounding environment.

Cantilevered Retaining Walls

Engineered for strength, cantilevered retaining walls utilise an arm that extends into the slope, distributing pressure down and away from the wall. This design allows for taller and thinner walls, saving space in the garden. Professional installation is recommended due to the technical knowledge required for their construction.

Sheet Piling Retaining Walls

Sheet piling walls are a great choice for gardens with limited space, consisting of long, thin sheets of metal or wood driven deep into the ground. They are particularly useful in soft soil areas or where water is present. The straightforward installation process can be beneficial for tight spaces, but it requires equipment and expertise to ensure the piling is driven deep enough for stability.

Anchored Retaining Walls

Anchored retaining walls offer the most flexibility, as they can be constructed using a variety of materials, including concrete blocks, timber or poured concrete, reinforced with anchors or cables driven deep into the soil behind the wall. This type is particularly useful for combating complex slope problems or where high loads are present.

Gabion Baskets

Gabion baskets are a more rustic choice, consisting of wire mesh baskets filled with rocks or rubble. This type of wall uses the weight of the fill material to resist the earth's pressure. Gabion baskets are highly permeable, making them an excellent choice for drainage solutions while also being environmentally friendly by using recycled materials.

Choosing the Right Type

When selecting the type of retaining wall for your garden, consider the height of the soil that needs to be retained, the overall aesthetic you wish to achieve, and, importantly, your budget. It's also crucial to consider the long-term maintenance and durability of the material you choose. For complex or tall walls, it is advisable to consult with a structural engineer or landscaping professional to ensure the stability and safety of the construction.
