Patio Block Tips: Having around eighteen blocks per row of the fire pit is a good rule of thumb. However, patio blocks vary in size and style, so the number of blocks may also vary depending on the width and desired look of the fire pit.
Dig the Fire Pit Hole
To begin, dig a round and shallow hole with a diameter of 45” and a depth of 6”. This will allow the first row of blocks to be laid belowground for greater stability. Check that the hole is even and flat all around using a level.
Blocks that come with interlocking lips are intended for retaining walls rather than stacked block projects like this one.
Prepare the Base
After the hole is dug and level, fill it with about 3” of paver base. Compact the base by tamping it down and use a level to make sure that the surface is even all over.
Add handfuls of paver base to any dips and smooth it out with the butt end of a mallet for a nice, level surface.
Lay the First Row
When placing the first row, ensure that every block set down is level before placing the next one. After each block is laid, use the rest of the paver base to fill in and level the gaps between them.
Lay the Rest of the Stones
While building the remaining rows, stagger the blocks by rotating each row’s pattern. Secure the rows by using landscaping adhesive between them and check that each row is level before starting on the next.
Add the Finishing Touch
Once the fourth and final row is placed and level, the fire pit kit can be placed on top. There is no need for anchoring or adhesives—the fire pit is ready for use!
