How to Build a Cinder Block Bench Seat

Transforming your outdoor space into a cozy, inviting haven is easier than you think. A cinder block bench seat not only adds functionality but also enhances the aesthetic appeal of your garden, patio, or balcony. Let's dive into a step-by-step guide on how to build a cinder block bench seat that's both sturdy and stylish.

Before you start, ensure you have the right tools and materials. You'll need cinder blocks, concrete mix, a trowel, a shovel, a wheelbarrow, a tape measure, a level, a rubber mallet, and safety gear including gloves and goggles. Having these on hand will make your project run smoothly.

Planning Your Bench Seat

Start by deciding on the size and design of your bench seat. Consider the space you have and how you want to use it. A simple L-shape or a straight bench can be both functional and visually appealing. Once you've decided on the design, sketch it out and measure the dimensions. This will serve as your blueprint during construction.

Also, consider the height of your bench. Standard cinder blocks are 8 inches high, but you can stack them to create a higher seat. Just remember to account for this in your design and ensure it's comfortable for seating.

Choosing the Location

Select a spot that's level and dry. If necessary, you can create a base of gravel or sand to ensure a stable foundation. Avoid areas prone to flooding or waterlogging to prevent damage to your bench seat.

Also, consider the proximity to your house or other structures. You'll want to be close enough for comfort but not so close that you're infringing on other spaces.

Gathering Materials

Based on your design, calculate the number of cinder blocks you'll need. Remember, each block will provide two courses (layers) of seating. So, if your bench is two blocks high, you'll need twice as many blocks as the length of your bench.

Don't forget to account for any additional blocks needed for support or decorative elements. It's always a good idea to have a few extra blocks on hand in case of breakage or mistakes.

Building the Bench Seat

Now that you've planned and prepared, it's time to start building. Begin by laying out your first course of blocks according to your design. Use a level to ensure they're even and straight.

If you're creating an L-shape or other complex design, you may need to cut some blocks. This can be done with a wet saw or a masonry blade on a circular saw. Always wear safety gear when cutting.

Laying the Foundation

Once your first course is laid, it's time to mix your concrete. Follow the instructions on the package to create a mix that's neither too wet nor too dry. You want it to be workable but not runny.

Using a trowel, fill the hollow cores of the blocks with concrete. Tap the blocks gently with a rubber mallet to ensure the concrete settles evenly. You may need to add more concrete as you go.

Building Up

Allow the concrete to set for at least 24 hours before adding the next course of blocks. This will ensure your bench seat remains stable and sturdy. Once the concrete is set, lay your second course of blocks, ensuring they're level and aligned with the first course.

Repeat this process until you've reached your desired height. Remember to fill the hollow cores with concrete at each stage to reinforce your bench seat.

Finishing Touches

Once your bench seat is built, you can add finishing touches to make it more comfortable and attractive. Consider adding a wooden seat or a cushion. You can also paint or stain the cinder blocks to match your outdoor decor.

If you live in an area with harsh winters, you may want to consider covering your bench seat when not in use to protect it from the elements.

Maintenance and Care

With proper care, your cinder block bench seat can last for years. Regularly inspect the bench for any cracks or damage. If you notice any issues, repair them promptly to prevent further damage.

To clean your bench seat, simply use a stiff brush and some mild soap and water. Rinse thoroughly and allow it to dry completely. Avoid using harsh chemicals as they can damage the cinder blocks.

Enjoy your new cinder block bench seat! Whether you're relaxing with a good book, enjoying a meal al fresco, or simply soaking up the sun, your outdoor space is now a cozy, inviting haven. Happy building!
