Types of Retaining Walls and Their Purpose
Gravity Retaining Wall
Using sheer weight and mass to hold soil at bay, this is the most common type of retaining wall. Since installation for this is mainly considering weight, these allow for the widest amount of variety when it comes to materials. Including bricks, pavers, and stone as just a few design options. Shorter walls may not require additional reinforcements, however, taller walls may require at least a small trench to be dug for the wall to sit into.
Sheet Piling Retaining Wall
These are typically used when space is an issue. A sheet pile retaining wall is a thin wall of steel, wood, or vinyl that is driven directly into the soil. Generally, sheet pilings will only work in softer soils. A good rule of thumb is that you must get 1/3 of the sheet piling driven into the ground.
Anchored Retaining Wall
An anchored retaining is exactly what it sounds like! This method allows for a variety of materials/styles and are supported by anchors. Typically, the anchors are driven into the earth behind them and attached by cables or strips. Furthermore, these anchors can be mechanically driven into the ground and their ends expanded by injecting pressurized concrete or by mechanical means. This method is used when there is a need for additional support to any of the above options and is often used for structurally thinner walls or ones with heavier loads to bear.
