Retaining walls can be an integral part of landscaping design, adding aesthetic appeal and allowing you to make the most of your property. If you’re planning an outdoor renovation, you might wonder what retaining walls are for, what materials can be used, and whether they're right for your project. Below are a few facts you should know about retaining walls before planning a landscaping project.

What You Should Know About Retaining Walls

What are retaining walls for?

If your property sits on sloping land or hills, a retaining wall allows you to cut into the soil to create a flat area. Landscaping engineers use a variety of techniques and designs to ensure the structure is strong enough to support the earth behind it. Depending on the terrain and application, a retaining wall may be just a few feet tall or several yards high.

What materials are used? 

Natural stone blocks are a popular choice for small retaining walls, especially for those often used in gardens and other residential landscaping projects. Larger structures often call for concrete blocks, which may need to be anchored deep into the soil for added stability.

Can retaining walls incorporate plants? 

Adding grass or plants between the blocks of a retaining wall may enhance the aesthetics of the structure, but they require additional planning. For instance, you’ll need to install an underground drainage system to keep excess water from damaging the wall, and carefully consider the types of plants you’ll use. As a general rule, avoid plants with long roots that need a lot of water.

How tall can a retaining wall be?

Using modern building techniques, landscape engineers can build retaining walls of almost any height, from a few inches to over 20 feet tall. However, walls over a specific height may require a building permit from your local city government. In Lexington, KY, walls higher than 23 inches require a permit before construction can begin.
