What is a Retaining Wall?

Gravity retaining walls rely on their own weight to resist the pressure of the soil behind them. These walls are typically constructed from heavy materials such as concrete, stone, or brick. Their sheer mass allows them to retain soil without requiring additional reinforcement. Gravity walls are simple in design and can be built to various heights, making them suitable for both residential and commercial applications. They are known for their durability and long lasting performance, especially in shorter structures.

Cantilever retaining walls use a slab and stem design, which distributes the pressure from the retained soil over a wide area. These walls are reinforced with steel bars to increase their strength and stability. Cantilever walls are typically used for medium height walls, such as those found in commercial properties or infrastructure projects. Their design allows them to handle a significant amount of pressure while using less material than gravity walls, making them more efficient for larger projects.

Sheet pile retaining walls are ideal for tight spaces or areas with soft soil. These walls are constructed using steel, vinyl, or wooden planks that are driven deep into the ground. They are often used in waterfront applications, such as along rivers, docks, and shorelines, where space is limited. Sheet pile walls are cost-effective and suitable for temporary structures or areas where deep excavation is not feasible. Despite their slim profile, they provide strong support and are quick to install.

Anchored retaining walls are used in situations where additional stability is required. These walls rely on cables or stays that are driven deep into the soil behind the wall and anchored to provide extra support. This design allows anchored walls to handle significant loads, making them ideal for high-load applications or when space is limited. They are often used in commercial construction projects where retaining soil over a larger height or heavier load is necessary.

Embedded retaining walls are partially embedded into the ground to increase their stability. These walls are typically made from materials such as concrete or steel, and their design allows them to resist high lateral pressure. Embedded retaining walls are commonly used in urban environments where space is at a premium and the need for strong support is critical. Their buried section helps anchor the wall, providing long-term durability in challenging settings.

Bored pile retaining walls are constructed by boring deep holes into the ground and filling them with concrete. This method is particularly effective in areas where deep excavation is required or where soil conditions are unstable. Bored pile walls are adaptable to various soil types, making them a versatile choice for a wide range of projects. These walls are often used in large-scale commercial or infrastructure projects that require deep foundational support.

Diaphragm retaining walls are built using reinforced concrete to create a continuous underground barrier. These walls are commonly used in large-scale infrastructure projects, such as basements, tunnels, and bridges. Diaphragm walls provide strong lateral support, making them ideal for deep excavations and situations where ground movement needs to be tightly controlled. Their ability to withstand significant pressure makes them an excellent choice for projects requiring substantial structural stability.
