How To Build A Fire Ring With Retaining Wall Blocks

A fire ring is the perfect way to gather around an open flame for cool nights and chilly evenings. With the right design, it can become a focal point in your backyard or campsite. Whether you’re building on a large plot of land or just want to do something special with your small campsite, here’s how you can build a great fire ring of your own

Select the right retaining wall block.

Retaining wall blocks are made of concrete or plastic, and they come in a variety of shapes and sizes. The most common block size is 8 inches x 16 inches x 16 inches (20 cm x 40 cm x 40 cm).

You can also find retaining wall blocks that are 12 to 14 inches (30 to 36 cm) in height. The weight of a retaining wall block depends on its composition: Some are hollow while others are solid, which affects the density and weight of the stone. Solid concrete retaining wall blocks weigh around 300 pounds (136 kg), while plastic ones may be lighter at around 150 pounds (68 kg).

Prepare the ground before you begin.

Before you begin, it’s important to prepare the ground for your fire ring. You will need to remove any debris, rocks and roots that might be in the area where you plan on building your fire ring. Any grass or weeds should also be removed from your chosen spot. Make sure there is no dirt or sand present in the area as well. After all of this has been cleared away and cleaned up, begin constructing your retaining wall block retaining wall with some basic tools including a shovel, bricks and mortar mix (which can be purchased at any hardware store)

Design the layout of your fire ring and calculate the number of blocks needed for your project.

My advice is to decide on the size, location and number of blocks before you start building. The easiest way to do this is by making a template out of cardboard or paper and marking it off as if you were going to build the fire ring with a shovel. This will help you see how many blocks are needed for the project, and where they should go.

Once you have decided on all of these things, then it’s time to move onto the next step: buying retaining wall blocks.

Gather the materials for your fire ring.

Before you begin, you will need to gather the following materials:

  • Retaining wall blocks that are made of concrete. These can be purchased at most hardware stores in your area.
  • Masonry sand, which is used as a form of cement and is available at many hardware stores. You will want to pick up enough masonry sand for your project so that you have enough left over after it has dried to make another fire ring with retaining blocks.
  • Mortar, also known as cement powder. This should be available at most hardware stores or home improvement centers where they sell masonry materials like blocks and sand; look for bags labeled “mortar powder” or “cement powder” on the shelf near where they store the mortar trowels (see below).

Level the base.

Next, you’ll have to level the base. This is a crucial step and one that requires a lot of attention to detail. If your fire ring doesn’t have an even base, you won’t be able to build up the sides at all. You can use a level, spade, shovel or wheelbarrow full of dirt/sand/gravel as long as it’s enough mass to level everything out on its own once you’ve put down some concrete blocks.

Build up the sides.

After you’ve laid out your first row of blocks, continue to build up the sides of the fire ring. If you’re using mortar, you’ll probably have to add more blocks as well as dig out deeper into the ground to create a retaining wall. If you’re using sand or gravel, however, you may be able to skip this step depending on how much material is available at the location where your fire ring will be built.

Determine how many steps are needed, if any.

Before you begin building your retaining wall, it’s important to first determine how many steps are needed. The height of the fire ring depends on what you are using it for. If you plan to use your fire ring for cooking, then you may need steps so that people can have a place to sit and eat around the fire ring. However, if you’re using this type of fire pit as an outdoor seating area or simply as a decorative feature in your yard, then no steps are necessary.

Build steps and add gravel, sand or mortar if needed to finish your project.

To build the steps, you’ll need a shovel and a pick. Start by digging out the dirt from where you want your fire ring. The size of your steps will depend on how big of a fire ring you want to create, but make sure that there is enough room for people to sit comfortably around it. Next, fill in the dirt with gravel so that it can hold up to moisture better than mud would and maintain its shape over time.[1]

If you don’t have access to gravel or sand—or simply don’t want them—you can also use mortar as an alternative. Mortar consists of sand mixed with cement; this mixture dries into rock-hard material that retains its shape after drying.[2] Mortar comes in two types: wet or dry; both methods provide adequate stability when building retaining walls.[3]

After building out your steps and adding any additional layers needed (e.g., mortar), finish off your project by adding some mossy rocks around them (this will help prevent erosion).[4] You may also want to add some sticks here or there as decoration if desired.

Your new fire ring will be a gathering place for outdoor fun, with or without a fire!

The fire ring is a great addition to your backyard. Whether you’re building it to have a fire, or just want to create an open space for gatherings, this project will be useful and fun. You can use the fire ring for more than just a fire! Besides adding aesthetic value, your new fire ring will be a gathering place for outdoor fun. It can also serve as a garden bed, planter box or even an additional seating area when friends come over.

It’s important to note that this project requires heavy lifting of blocks (about 80-100 pounds each), so please consult with your doctor before beginning construction if you have any health concerns about lifting heavy objects.


Now that you have the knowledge to choose, layout and build your fire ring, you can enjoy its warmth on chilly nights and its gathering place for family and friends. Whether you decide to use it as a fire pit or just an installation in your backyard, taking pride in building it yourself will make it even more enjoyable.
