There’s something nostalgic about sitting around a fire pit. Considered one of the most popular landscaping features, backyard fire pits are functional, attractive and a great outdoor gathering place to incorporate in the design of your home. In this week’s blog, we share how to build an outdoor fire pit.
1) Plan Your Fire Pit Design
The first thing you want to do is plan your fire pit design. This is where you can unleash your creativity and flare. Just make sure the firepit is made from fireproof material on a flat, level area. It should also be several metres from a house or tree. Be sure to check the local laws and regulations on fire pits in your city or area.
2) Build the Foundation
After deciding what your fire pit will look like, it’s time to start building. Begin by pounding a rebar stake into the ground to mark the centre of the fire pit, then draw the circumference of the circle. Next, measure the diametre of your circle. Attach a string to the stake that is half the length of your circumference and tie this end of the string to a can of spray paint. Lightly pull the string tight and walk around the stake as you spray paint your circumference. Using a shovel, dig the space out to a depth of 6″. Use the same method as above to mark an inner circle 12″ in from the outer circle – this will form the edge of the fire pit wall.
Next, create the foundation that the stones will sit on. Mix concrete with water until it reaches a creamy consistency. Lay the wet concrete in between the two circles so it’s level to the ground. Make sure to leave the centre space free to allow for drainage. Keep building the concrete until it is approximately 1 ½” below ground level. Press the rebar into the concrete for reinforcement and smooth the surface with a towel before allowing it to dry for 24 hours.
3) Build Outer Wall
Mix mortar and then shovel around 2″ of it on top of the concrete base. Lay the stones on the mortar. Select stone faces that are appealing and match the curve of your outline. After the first few levels of stone start to build, start laying the inner fire bricks.
4) Build the Inner Fire Brick Wall
To build the inner fire brick wall, fill in the gaps between with wet mortar, scraping away any excess. Measure the inner and outer edges of the wall to keep the wall’s thickness and circular shape. Keeping raising the bricks and stones to fill in any gaps between the stones and mortar. Lay a cap of pre-selected flat fieldstones on top of the wall to finish the structure.
