Its a bit tricky to get the heavy slabs in an exact circle with a consistent height but its best to prop them up and backfill with the gravel so that each stone is buried 150mm leaving a 450mm deep pit. The top of the granite should be 200mm above the surrounding ground level to allow for the concrete slab and paving. You could cut each stone lengthwise along one edge to make them fit flush with each other but it isnt necessary. The bottom of the pit was then paved to make shovelling out the ashes easier.
Your next step is to start digging! Since youve already decided on the size of your firepit, all you have to do is dig an appropriately sized hole. Next, use bricks of the same height and place them at the surface level of the pit. From there, begin creating simple stacked rows, making sure to offset the vertical joints of each brick. When your pit has reached your desired and pre-planned height, youre ready to move on to the next step. Support the bricks you have laid by adding firmly packed soil around the area. You can also use gravel for the floor of the pit, smoothing as you add it in. Your final step is to add in top caps to the walls.
Once the stone lining was completed we used an excavator to place the large stone seats. Depending on the size of the stones they may have to be dug into the ground or set higher on gravel to give them an approximately consistent height. Bearing in mind that a comfortable adult seat height should be 300 - 400mm the stones need to conform to this measurement. By the time the concrete is poured and the paving laid the finished ground height will be 150mm higher than existing ground level, meaning that the rocks should stand 450 - 550mm above the ground.
You will want to use an appropriate adhesive material, such as mortar, to keep the caps firmly in place. Be sure to apply the caps only to dry surfaces and to keep them level during the process. Believe it or not, once youve done this, youre ready to try out your new firepit! Make sure to take proper care of your firepit so that you can enjoy it for many years to come. Always clean the ashes from your pit one day after use. If you have decided to paint your pit (using fire resistant paint, of course), it may need touch-ups from time to time to continue looking its best. Make sure that water is never used to put out fires, as this can cause the firepit to break down faster. Youll also want to invest in a good firepit cover for when the pit is not in use.
