Can you build a bench with concrete blocks?

When it comes to creating outdoor seating on a budget, concrete blocks may not be the first material that comes to mind. However, with their durability, versatility, and affordability, these simple building blocks can be transformed into a sturdy and unique bench. In this article, we will explore the steps and considerations involved in building a bench using concrete blocks.

Choosing the Right Materials:

Before getting started, it is essential to gather all the necessary materials. Here’s what you’ll need:

1. Concrete blocks: Opt for standard-sized blocks with straight edges and a consistent shape.
2. Pressure-treated lumber: Use 2×4 or 4×4 lumber for the bench seat and backrest.
3. Adhesive: Invest in a strong construction adhesive to secure the blocks together.
4. Leveling material: Include crushed gravel or crushed stone to ensure a stable base.

Planning the Bench:

To create a functional and aesthetically pleasing bench, it’s crucial to plan its design and dimensions properly. Consider the following factors:

1. Size and shape: Determine the desired length and depth of the bench seat. Take into account the space available and the number of people it should accommodate.
2. Backrest: Decide whether you want your bench to include a backrest for added comfort and support. You can construct a simple vertical backrest or explore more elaborate designs.
3. Seat height: Ensure the bench is comfortable by considering the average height of potential users. A standard bench height is between 16 to 20 inches.

Building the Bench:

Now that you have your materials and the design is in place, it’s time to start building the bench. Follow these steps:

1. Prepare the area: Clear the construction area of any debris or vegetation. Use a string or rope to mark out the dimensions of the bench.
2. Level the ground: To create a stable foundation, remove any topsoil and level the ground. Add a layer of crushed gravel or crushed stone, ensuring it is compacted and level.
3. Secure the blocks: Lay the first course of concrete blocks, ensuring they are evenly spaced and level. Use the construction adhesive to stack the additional courses of blocks, securing them together firmly.
4. Add the lumber: Place the pressure-treated lumber horizontally across the top of the blocks to create the bench seat. Secure it in place by attaching it to the blocks using screws or angle brackets.
5. Attach the backrest: If you’ve decided to include a backrest, attach the lumber vertically to the bench’s rear side. Ensure it is securely fastened, providing stability and support.

Finishing Touches:

To enhance the bench’s appearance and functionality, consider these finishing touches:

1. Sealing the blocks: Apply a waterproofing sealant or masonry sealer to protect the blocks from weathering and discoloration.
2. Cushioning: Add cushions or foam padding to the bench seat and backrest for added comfort and style. Ensure they are weather-resistant and easy to clean.
3. Decoration: Personalize your bench by painting the concrete blocks or staining the lumber to match your outdoor aesthetic. Consider adding plants or accessories nearby to create a welcoming atmosphere.

Building a bench with concrete blocks is an affordable and creative way to add seating to your outdoor space. By carefully planning the dimensions, selecting the materials, and following the step-by-step process, you can construct a sturdy and visually appealing bench that will provide years of enjoyment. Whether for a backyard, garden, or patio, this DIY project offers endless possibilities to customize your outdoor seating area.
