Fire pits add a warm and cosy element to a patio, making the outdoors winter-accessible. The best kind of patio for constructing a raised fire pit is a concrete or paved patio that is fireproof. You can make a raised fire pit on a wood patio, but you will need to purchase a fire pit insert to ensure that the pit remains safe on the combustible wood subfloor. Building your own raised patio fire pit on a fireproof subfloor is simple.
Chalk the desired dimensions of the fire pit base onto the concrete or paved patio in the area where you want to build the pit. The base should be around 10 inches wider on all sides than the fire pit. Design the fire pit and base into any shape you like, round, square, hexagonal -- all will work.
Lay a single course of bricks into the base area, packing them tightly together. Mix a batch of surface-bonding cement in a wheelbarrow or bucket, following the manufacturer's instructions. Use a trowel to spread on a 1/2-inch-thick layer over all the bricks in the base, feathering out around an inch of cement onto the surface of the patio. Leave to dry overnight.
Chalk the dimension of the fire pit onto the base and lay a single line of bricks around the chalked dimensions for the first row of the fire pit walls. Lay a second, third, fourth and fifth row on top, staggering the joints of the bricks.
Mix a second batch of surface-bonding cement and apply a 1/2-inch-thick layer over the fire pit walls as you did the base. Feather out around 2 inches of the cement from the walls into the base. Leave three days to fully cure.
Line the bottom and inside of the fire pit walls with firebricks before lighting a fire.
For wood patios, make a two-brick-thick base to place the fire pit insert over and build the walls of the pit around the insert. Check the pit insert manual for specific safety instructions. Place a grill plate over the top of the fire pit to turn it into an impromptu barbecue grill.
Never leave children or pets alone when a fire pit is burning.
