Concrete block retaining walls are becoming more and more popular amongst homeowners and commercial property owners as a reliable and versatile solution to landscaping needs. These type of walls are created by stacking large, interlocking blocks, which are then fastened together using a combination of adhesive and steel rods. The result is a sturdy, durable wall that can withstand the test of nature’s elements such as soil erosion, water runoff, and heavy winds. Additionally, because of their flexibility in size and shape, concrete block retaining walls can be used to create a variety of landscape features from edging, planters, and garden beds to stairs, columns, and outdoor living spaces. This article will explore the benefits of concrete block retaining walls, their structural properties, and the installation process.

What Are the Benefits of a Concrete Block Retaining Wall?
If you live on a sloped property or near a body of water, erosion is a common issue that you’ll face. Erosion can cause damage to your property, increase flood risks, and lead to soil and water contamination. A concrete block retaining wall is a reliable and effective solution to prevent erosion and protect your property. In addition to preventing erosion, here are some other benefits of a concrete block retaining wall:
1. Durability
Concrete block retaining walls are incredibly long-lasting due to the strength and durability of the material. Concrete blocks can withstand extreme weather conditions such as heavy rain, strong winds, and freeze-thaw cycles. This means that investing in a concrete block retaining wall can save you money in the long run as it requires minimal maintenance compared to other materials.
2. Versatility
Concrete blocks come in a variety of sizes, shapes, and colors, making it easy to match the style of your home and landscape. You can choose between different textures and finishes to create a wall that’s unique to your property. You can also use the blocks to create various designs and patterns for added visual interest.
3. Cost-Effective
When compared to other materials such as natural stone or brick, concrete blocks are a cost-effective option. The manufacturing process of concrete blocks is highly efficient, resulting in a lower cost per block. In addition to the lower cost of materials, the installation of concrete block retaining walls is also less labor-intensive, further reducing the overall cost.
4. Low Maintenance
Concrete block retaining walls require minimal maintenance due to their durability and resistance to damage. Unlike wood, concrete blocks do not rot or decay, and they do not require regular painting or staining. A simple cleaning with a hose or pressure washer is all that’s needed to maintain the appearance of the wall.
5. Increases Property Value
A concrete block retaining wall can increase the value of your property, as it helps to prevent erosion and protect your home from potential damage caused by soil movement. It also adds visual interest to your landscape and can be a selling point to potential buyers.
In conclusion, a concrete block retaining wall is a practical and versatile solution to prevent erosion, protect your property, and add aesthetic value to your landscape. With its long-lasting durability, low maintenance requirements, cost-effectiveness, and versatility, a concrete block retaining wall is an excellent investment for any homeowner.
Creating a Concrete Block Retaining Wall
Now that you have all the necessary supplies and information, you’re ready to begin building a concrete block retaining wall. Here are a few steps to follow:
1. Excavation and Grading
The first step in creating a concrete block retaining wall is excavating the site and grading the area. This involves removing all the soil and debris from the construction area using a backhoe or hand shovel until you reach the desired depth for the foundation. The depth of excavation will depend on the height and width of the retaining wall and the type of soil on the site. If you’re unsure about the depth, consult a qualified excavation contractor.
Grade the area properly so that water flows away from the wall. You can use a laser level or string line to ensure the grade is level. Once you have the excavation and grading completed, add several inches of gravel to the bottom of the trench.
2. Building the Foundation
After excavation and grading, it’s time to build the foundation. Depending on the height and width of the wall, you may need to contact a qualified masonry contractor to pour a concrete footer. The footer should be at least twice the width of the wall and extend below the frost line. Once the footer is poured, add several more inches of gravel to the top of the footer.
If the retaining wall is less than 3 feet in height, you can start building the retaining wall directly on top of the gravel. However, if the wall is over 3 feet, it’s best to add a course of capstones or decorative brick for added stability. The capstones should be embedded in mortar to help bond the wall together.
3. Laying the Blocks
Now it’s time to start laying the blocks. Start at the corners and work your way in. You can use the string line to keep the blocks level and straight. Use adhesive to keep the blocks securely in place. Install drainage pipes behind the wall if required.
It’s important to lay the blocks carefully, making sure that each course is level and straight. If the blocks are uneven, the wall will be unstable and not retain the soil properly. Be sure to stagger the blocks for added stability.
4. Backfilling and Compaction
After laying all the blocks, the next step is to backfill the area behind the wall with gravel or crushed stone. This will help with drainage and prevent water from building up behind the wall, which can lead to erosion. Once you have filled the area with gravel or crushed stone, compact it thoroughly with a plate compactor. Continue filling in the area until you reach the top of the wall.
5. Finishing and Sealing
Finally, the last step is to finish and seal the retaining wall. Add a layer of topsoil and sod to the top of the wall. This will help prevent erosion and give the wall a finished look. You can also use a sealant to protect the retaining wall from water damage and erosion. Be sure to consult a qualified contractor to find the right sealant for your retaining wall.
