What Exactly Is a Retaining Wall?

Put simply, a retaining wall is installed to hold back soil (occasionally water). They can be constructed of a variety of materials, including cut stone, wood, brick and even natural stone, giving the homeowner a lot of variety in aesthetics. These structures are most often created to add a tiered effect to landscape, holding soil back from spilling over into a yard, and are most commonly seen in homes with a dramatic incline in the yard.

There are four common types of retaining wall, including:

  • Gravity walls. These essentially hold back the soil by their own weight, with no special anchors or designs to aid in soil retention. Gravity walls are often used in residential property.
  • Cantilevered. Cantilevered retaining walls use a structurally reinforced “footing” to improve load retention, and to reinforce them against extreme force. Cantilevered walls often make use of ‘buttresses’ to further improve integrity.
  • Piled. These walls are usually constructed from steel, or wood plank set into the soil at 1/3 of their total height. Piled walls are particularly beneficial to tight spaces.
  • Anchored. More of a supplement than a unique design, anchors can apply to all other types of retaining wall, and simply denote the use of cable anchors to reinforce the wall.

How High Should My Retaining Wall Be?

There are a number of factors that come into play to dictate the height of your retaining walls. On average, most retaining walls are between three and four feet high. This is optimal because it doesn’t require any anchors, or expensive engineering methods, though in some cases the wall must be higher. Variables that affect the height of your wall include:

  • Extreme heights. Your wall requires a measure of clearance over the soil to ensure structural integrity. In most cases this will not exceed the 3-4 foot standard, but for some landscapes, it may.
  • Unique designs. You can readily find retaining walls exceeding even six feet in residential properties. These walls must be engineered specially, and often require a number of unusual considerations.
