Henriette Firepit February 27th, 2018 - 11:07:16
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.
When you buy a new copper firepit there are some safety issues that you will want to follow. One of the most important things to keep in mind is the weather. If your area has issued a fire warning of any type you wont want to start a fire outdoors. In dry areas it is better to be safe than to be sorry. If there is no fire warning remember also that you need to keep your fire under control. Make sure that your fire doesnt get too big, and keep a screen on the firepit so that there wont be any burning embers or ashes flying away from the fire.
Procedure: First, we excavated a pit approximately 1metre (3 feet) in diameter and 800mm deep. The ground we were working on was very rocky so we used a backhoe and it was difficult to carve a smooth hole as you can see by the photos. Next we dug a drainage channel from the bottom of the hole to a lower point beyond the extent of the fire area. This was essential in this circumstance due to the heavy rainfall and the heavy soil. If your soil is porous it may not be necessary to provide drainage to the pit. In the channel we laid the plastic drainage pipe and covered it with gravel. Because we wanted to line the pit with the 600mm granite slabs we placed extra gravel in the bottom of the pit to set the stones on upright in a circle.
Most people find it relaxing and satisfying to sit in front of a the flames of a fire. No wonder we find so many homes with fireplaces. In the last few years many have discovered they can enjoy that same feeling out in their back yard or patio by choosing from a large variety of outdoor firepits on the market today. During the more pleasant outdoor months of the year weather-wise, people try to enjoy the outdoors as frequently as they can. Unfortunately they have to work during the day and usually they time they have to spend outside is in the evening when it often is dark. Outdoor firepits make such a situation something to look forward to and provide a savings in electrical lighting costs. If you are not enjoying such an experience, imagine sitting by the fires glow with the kids in bed, enjoying good company sipping on your favorite beverage.
