The Basics of Outdoor Fireplace Construction
Building an outdoor fireplace requires a little planning and attention to detail. You must pick the right location, choose the appropriate materials, and work with a masonry professional to ensure the job is done well. It is also important to consider how the fireplace will be used and the ambiance that you desire for your space.
Before laying the bricks, it is essential to prepare the foundation for the firebox and chimney cap. Dig a hole 3 feet deep and a few inches wide, and then pour in concrete blocks to create the firebox foundation. Use a small amount of Sandcrete to make the base and then let it cure for at least a few days.
You can also lay cinder block bricks, which are made from CMU material and are ideal for this project. Once the foundation is set, begin laying the firebox bricks and mortar them to the concrete slab. This is known as a “U” shape, and will give you a nice level surface for the bricks to rest on.
Once you have laid your first course of bricks, spread a thin bed of mortar on top. You can either use ordinary bricking mortar or a specially formulated fire cement. The latter is a more efficient choice, as it can be used without the need to mix it in water.
Depending on the size of your fireplace, you might need to build a firebox with more than one layer of bricks. To make the firebox more stable, it is recommended to lay a layer of pier blocks or corner blocks on each side of the fireplace. These are the same as a standard block except that they have a half-block joined on the side, which makes it more solid.
Next, construct the flue using a 2 feet tall ceramic flue pipe. Put it on the angle bar and cover the holes with firebricks or a mixture of bricks and cement. You can then place fire clay on the holes and spaces for sealing purposes. Once the smoke chamber is completed, you can add the fireplace chimney cap and finish with veneers of your choice.
The construction of an outdoor fireplace can be an exciting and fun project for homeowners. It will not only add value to your home, but will help to create a warm and inviting space for you and your family to enjoy.
Whether you’re looking to create a backyard space that will be enjoyable for you and your guests, or you want to create a place to entertain family and friends, an outdoor fireplace is a great addition to any home. With the right design and seating options, you can create a comfortable and beautiful space for your guests to enjoy year-round.
When designing your outdoor fireplace, it is a good idea to consult with a masonry expert and discuss the importance of the landscape around the fireplace area. This will not only ensure that your masonry will not damage the landscape, but will also keep it looking neat and clean.
