How Gravel, Wood, And Rock Are Used In Retaining Walls

Posted on

Retaining walls are an important part of your home's landscape. They serve multiple functions. They are both decorative as well as functional. A retaining wall will make your property look nicer and make sure the soil does not erode.

When it comes time to have a retaining wall installed, it's important to understand the different materials that will be used in the construction. So, this article will cover three of the main items that you might use when installing a retaining wall. Each is important and should be understood before you proceed with your project.

How Gravel Is Used in Retaining Walls

Gravel is a material that you'll not see when you look at a retaining wall, but it's one of the most important parts. When the wall is designed, gravel is used to backfill the area. The wood and retaining wall blocks are never placed directly against the dirt. Instead, gravel is used to be a more secure backing. It's a foundational element that helps make sure that the retaining wall does not shift and move over time. Gravel will not shrink or dust away like regular dirt, so it's a more appropriate

How Wood Is Used in Retaining Walls

Wood is also an important part of the retaining wall design. At the minimum, pressure-treated wood will be used as a frame to hold the retaining wall blocks. In some situations, the majority of the wall might actually be designed with pressure-treated wood as the main structural element.  The main reason that people would use wood as a prominent feature of their retaining wall is that it provides a different aesthetic. Some people who have log cabin homes, or rustic wood bungalows, might prefer the look of a wood retaining wall.

How Rock Is Used in Retaining Walls

Rock is a major component of retaining walls. Rocks are the visible element for most retaining walls. These rocks are either fabricated retaining wall blocks or natural rocks that are used to create the main façade of the retaining wall.

Depending on the severity of the property's slope and grade, the retaining blocks can be situated right against the wall with only a backfill of gravel. A more gentle slope with a small retaining wall does not need to have serious reinforcement. If, however, the incline is quite steep, there should be a framework of either rebar or pressure-treated wood installed to steady the wall.
