Building Outdoor Fireplace Using Concrete Cinder Blocks

Building an Outdoor Fireplace Using Concrete Cinder Blocks

Building an outdoor fireplace using concrete cinder blocks is a relatively straightforward project that can be completed in a weekend. With a little planning and effort, you can create a beautiful and functional addition to your backyard that will provide years of enjoyment.

Here are the essential steps to follow when building an outdoor fireplace using concrete cinder blocks:

1. Choose a Location

The first step is to choose a location for your fireplace. The ideal location will be level, well-drained, and away from any flammable materials. You will also need to consider the prevailing wind direction so that smoke is not blown towards your house or other structures.

2. Gather Your Materials

Once you have chosen a location, you will need to gather the following materials:

Concrete cinder blocks
Mortar mix
Firebricks
Fireplace grate
Chimney flue kit
Concrete sealer (optional)

3. Build the Base

The first step is to build the base of your fireplace. This should be a level platform made of concrete cinder blocks. The size of the base will depend on the size of your fireplace. Once the base is complete, you can begin building the walls of the fireplace.

4. Build the Walls

The walls of the fireplace are built using concrete cinder blocks. Start by laying a row of blocks around the perimeter of the base. Use mortar mix to hold the blocks together. Once the first row is complete, you can begin adding additional rows of blocks. Be sure to stagger the joints between the blocks for added strength.

5. Install the Firebox

Once the walls of the fireplace are complete, you can install the firebox. The firebox is the area where the fire will burn. It should be lined with firebricks to protect the concrete cinder blocks from the heat of the fire. You will also need to install a fireplace grate to support the firewood.

6. Install the Chimney

The final step is to install the chimney. The chimney will allow smoke and fumes to escape from the fireplace. You can use a prefabricated chimney flue kit or build your own chimney using concrete cinder blocks. Be sure to follow the manufacturer's instructions for installing the chimney.

Once the chimney is installed, your outdoor fireplace is complete. You can now enjoy a warm and inviting fire in your backyard.
