Henriette Firepit February 27th, 2018 - 11:01:42
The reinforced concrete was poured to a depth of 100mm, allowing the firepit lining stones to protrude 100mm above it, with a slope of 1:100 away from the pit. Letting the concrete cure for a week, we then laid out random limestone pieces to gauge the best arrangement. Random stone comes in varying thicknesses and sizes and takes a great deal of patience to lay properly. You can simply start laying and choose matching pieces, filling in the many small gaps with small pieces but we prefer to shape the stones so that gaps are consistent and the small pieces are minimal. Once the stone was shaped and mortared down the gaps were grouted with mortar, coloured to match the stone. The final thing was sealing the limestone with a good quality stone sealant. And there is your party feature! When you light a fire and let it burn for a few hours the limestone patio begins to heat up and radiate to the surrounding seats making a very cosy spot on a cool autumn evening.
Once youve figured out just what to do with the hole, lets look at some decorative edging. Again you can opt to just leave the sides bare. Leaving a gaping hole in the ground probably isnt the greatest idea, someone could trip and fall into the pit. So here are some edging options going again from least to most expensive. Use the dirt that you excavated from the pit to build a berm around the edge of the pit. Like with leaving the hole unlined, youll have to worry about wash out. The next method is to place large rounded stones around the perimeter. The stones can get expensive but youll only need a couple dozen to finish off the edge.
Your first step is, of course, to choose where your firepit will go. Pick an area that doesnt present a fire hazard and that will be comfortable for you and your guests to sit and relax. If, for example, you know one part of your yard is prone to mosquitoes, you would certainly want to avoid that spot. Just think practically, and you should be fine! When youve decided on the size and location of your pit, mark it using chalk or paint. If there is sod in the area, youll need to remove it, and you should also use a pre-emergent herbicide in order to prevent grass from growing in that area again.
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.
