Building a retaining wall is a decision that speaks to a commitment to the landscape. Retaining walls are some of the oldest and longest-lasting structures humans have ever made, and some examples of these walls go back over many thousands of years. Today, there is a variety of materials and methods used to build both structural and decorative retaining walls. Here’s a guide at choosing the right materials for a retaining wall project at a masonry supply near Lancaster, PA.

Purposes of a Retaining Wall

Retaining walls are designed for the primary purpose of holding back soil and minimizing the effects of erosion. They are also often incorporated with the intent of creating more usable space. Beyond their utilitarian purposes, retaining walls can become focal points in the landscape. They can be adorned with gorgeous patterns and color schemes, and serve as surprisingly wonderful design elements. They are structures that can support or house pieces of art, light fixtures, plantings, or even serve as seating for patio, pool, and fire pit areas. 

Natural Stone

Natural stone has been the primary construction material of retaining walls for thousands of years. The material has always been strong and long-lasting. Look for locally quarried stones to achieve the most beautiful integration into the environment. Of course, all stone choices are naturally gorgeous, and you can be assured of a 100 percent unique retaining wall when you opt for natural stone. 

The drawback is that the installation process can take longer as the stone slabs are heavy, and they must be selected, cut, and carefully placed into the wall, but the end result can be worth it: a one-of-a-kind and sturdy wall with character.

Keep in mind, stone walls should be carefully engineered if they are to be higher than 3.5 feet; the weight of the stone alone isn’t always enough to withstand the pressure of the soil behind the wall.

Concrete Blocks

Traditional concrete blocks are often used for building retaining walls on a budget. They can make up the superstructure of the retaining wall. Since they are designed to fit together perfectly and are much lighter in weight than natural stone, they can speed up the construction process. Concrete wall units are available in a variety of styles. 

Concrete Blocks with Veneers

Landscapers often use plain concrete blocks as the structure of a retaining wall and then add a natural stone or manufactured stone veneer. Adding a veneer to concrete blocks allows for creative expression, as veneers can be mixed and matched to suit the decorating style. Often, an accent band is used to add interest and to pick up a specific color in the landscape or home.

Creating Exciting Visuals

Capstones are the finishing touch for a retaining wall. Choose from natural stone or manufactured stone—and it’s not uncommon to mix the two to achieve the desired look.

Niches, built-in seating, pillars, steps, and even water features are a few ways to add drama and interest to a retaining wall. This is an opportunity to mix and match materials, or to create a simple structure using just one material.

For best results, you may want to use the same material for steps and capstones.
