First, you will need to consider the location of the fire pit. Be sure to check with your local town’s ordinances and HOA rules to make sure you are complying with all regulations.

Fire Pit PlacementTip: It is also a rule of thumb to place the fire pit on a flat surface that is at least 10 feet away from the nearest structure or trees to avoid any fires. Another thing to consider is prevailing wind direction. Knowing this will allow you to select a spot that will keep smoke and embers from blowing in your face to a minimum.

To make a Square Borealis Fire Pit that measures 4’8” x 4’8” x 1’ 6” you will need:

  • 12 pieces of Borealis Wall (16 pieces come on one pallet).
  • 88 Fire Brick
  • 1 – 10lb pail of High Heat Mortar
  • 1 tube of Construction Adhesive
  • 6 – Five gallon buckets of 3/4″ Crushed Stone

To start the first course place one Borealis slab down on the 48” long side to begin making the perimeter of the fire pit. Place another Borealis slab above the first slab so that it is running perpendicular to the first piece. The 48” length of the Borealis unit plus the 8” depth of the second Borealis unit added together will be the fire pit’s 4’8” length. Place another two slabs on the opposite side to complete the square and finish the first course.

For the second row repeat the process but stagger the Borealis slabs, as shown in the side view diagram. Use concrete adhesive to secure the slabs in place. Repeat the process for the third course. Again glue down the course with adhesive to secure in place.

Next you will want to line the inside of the fire pit with refractory brick, otherwise known as fire brick. These bricks are made to within stand temperatures as high as 2700 degrees so they will act as a protective barrier between the Borealis and the fire. You can mortar the fire brick together will high heat refractory mortar.

Once you have lined the fire pit with fire brick, fill the center about 6” high with ¾” crushed stone. The ¾” crushed stone will allow for drainage and protect the ground from the fire.

And you’re done! It’s that easy to make a Borealis Fire Pit and you can add significant value to your home!

Borealis Square Fire Pit w/ Metal Lining Alternative:

If you wish to use Techo Bloc’s heat resistant sleeve for the lining of your Borealis Fire Pit rather than the fire brick then you will have to make minor adjustments to the fire pit.

The fire pit will need to be made smaller to accommodate the sleeve which measures 28” x 28” x 18”. To do this the outer perimeter of the Borealis will need to measure 44” long. Cut the Borealis slabs down to 36” to accommodate this size. Stagger and secure the next two rows of slab. Insert the sleeve to line the fire pit and fill the bottom with about 6” of ¾” crushed stone.
