In this comprehensive guide, we will walk you through the step-by-step process of creating your own sleek square backyard fire pit. So, grab your tools and let’s get started!

Materials You Will Need

  • Concrete blocks (16)
  • Concrete adhesive
  • Fire bricks (36)
  • Fire pit insert
  • Gravel
  • Sand
  • Tape measure
  • Masonry saw
  • Trowel
  • Level
  • Rubber mallet
  • Fire-resistant gloves

Step 1: Choose the Perfect Location

The first step in creating your sleek square backyard fire pit is to choose the perfect location. Consider factors such as proximity to your seating area, wind direction, and any local regulations regarding fire pits. Once you have selected the ideal spot, mark the area using stakes and string.

Step 2: Prepare the Foundation

Now that you have determined the location, it’s time to prepare the foundation. Start by clearing the area of any debris or vegetation. Dig a shallow hole, approximately 6 inches deep, within the marked boundaries. This will serve as the foundation for your fire pit.

Step 3: Level the Ground

Using a level, ensure that the ground within the hole is perfectly level. This will provide a stable base for your fire pit. Make any necessary adjustments by adding or removing soil until the ground is level.

Step 4: Add Gravel

Next, add a layer of gravel to the bottom of the hole. This will aid in drainage and prevent the fire pit from sinking into the ground over time. Spread the gravel evenly, ensuring that it covers the entire area.

Step 5: Lay the First Course of Blocks

Now it’s time to start building the fire pit. Begin by laying the first course of concrete blocks along the perimeter of the hole. Use a tape measure to ensure that the blocks are evenly spaced and aligned. Apply a thin layer of concrete adhesive between each block to secure them in place.

Step 6: Build the Second Course

Once the first course is in place, it’s time to build the second course. Stagger the blocks so that they overlap the joints of the first course. This will create a sturdy and visually appealing structure. Again, use concrete adhesive to secure the blocks together.

Step 7: Continue Building

Continue building additional courses of blocks until your fire pit reaches the desired height. Remember to stagger the blocks and use concrete adhesive to ensure stability. Take breaks to step back and admire your progress!

Step 8: Add Fire Bricks

Now that the structure of your fire pit is complete, it’s time to add fire bricks to the interior. Fire bricks are designed to withstand high temperatures and will protect the concrete blocks from heat damage. Lay the fire bricks in a circular pattern, using a masonry saw to cut any bricks that need to fit snugly.

Step 9: Install the Fire Pit Insert

Once the fire bricks are in place, it’s time to install the fire pit insert. This metal insert will contain the fire and provide a safe and efficient burning area. Follow the manufacturer’s instructions to properly install the insert within your fire pit.

Step 10: Fill with Sand

To further protect the concrete blocks and fire bricks, fill the bottom of the fire pit with a layer of sand. This will act as a buffer and prevent direct contact between the fire and the materials. Spread the sand evenly, ensuring that it covers the entire bottom surface.

Step 11: Enjoy Your Sleek Square Backyard Fire Pit

With the fire pit fully assembled and prepared, it’s time to sit back, relax, and enjoy the warmth and beauty of your new addition. Gather some firewood, put on your fire-resistant gloves, and light up your sleek square backyard fire pit. Invite your friends and family over for a cozy evening under the stars.
