Affordable Landscaping Cement Block Fire Pit

Building a beautiful fire pit in your backyard is easier and cheaper than you think!

This DIY project from Tools 2 Tiaras is just one example of a fire pit that is easy to do, easy on the wallet, with no limits in terms of design. The owner-builder spent about $20 on the project. He was able to build it to the size he wanted with just that amount! How? By making use of landscape and cinder blocks that were already in the house when he bought it.

While not everyone has landscape blocks lying around their backyard, this material is still one of the budget-friendly options for a gorgeous cement block fire pit. You can first look at buying excess blocks from a friend or neighbour, at a lower price. You can also find a cheap fire pit base from a thrift store as another option.

Is this the kind of fire pit that would make a great addition to your backyard?

Take inspiration from the various examples of a fire pit made from landscape and cinder blocks below!

Building a Landscaping Cement Block Fire PIt

Materials:

• Cement Landscape Edging
• Landscaping Blocks
• Cinder Blocks
• Landscape Adhesive
• Cement Mix

Tools:

• Shovel
• Spirit Level

Steps:

Step 1: Choose and Prepare the Location
Pick a safe, open area in your backyard. Make sure the spot is away from trees, structures, or anything flammable. Clear the area of grass, roots, and debris. Use the shovel to dig out a shallow circle or square where your fire pit will sit. Aim for a depth of about 4 to 6 inches.

Step 2: Level the Ground
Once you’ve dug out the area, use the shovel to flatten the surface as much as possible. Take your spirit level and check that the ground is even. This will help keep your fire pit stable and safe.

Step 3: Lay the Cement Landscape Edging
Place the cement landscape edging around the perimeter of the pit area. This will act as a border and help keep your fire pit structure neat and contained. Make sure the edging is level as you go. Adjust the ground if needed.

Step 4: Create the First Layer of Cinder Blocks
Arrange the cinder blocks in the shape you want—either a circle, square, or rectangle. Leave small gaps between the blocks for airflow. Use the spirit level again to make sure the blocks sit evenly. A level base is key to a sturdy fire pit.

Step 5: Apply Landscape Adhesive and Add More Layers
Once your first layer is level and in place, apply landscape adhesive to the tops of the cinder blocks. Add the next layer of blocks, staggering them like bricks. This creates a stronger structure. Press each block down firmly so the adhesive bonds well. Continue this process until you reach the desired height, typically three or four layers.

Step 6: Add Landscaping Blocks for the Outer Wall (Optional)
Add a layer of landscaping blocks around the outside of the cinder block structure for a polished look. Secure these with landscape adhesive. This gives your fire pit a finished, decorative appearance.

Step 7: Mix and Pour Cement (Optional for Extra Strength)
Mix your cement according to the package instructions if you want a stronger, more permanent structure. Pour a small amount into any gaps between the blocks, especially around the base. Smooth it out with your shovel or a trowel if you have one. Allow the cement to cure fully before using the fire pit.

Step 8: Final Check and Clean-Up
Give the entire fire pit a once-over. Make sure everything is stable, level, and secure. Remove any extra adhesive or cement mix. Let the adhesive and cement set for at least 24 hours before using the fire pit.

Step 9: Enjoy Your Cement Block Fire Pit
Once everything is dry and secure, your new fire pit is ready to use. Add firewood, light it up, and enjoy a cozy evening outdoors.

Choosing the Right Cement Blocks for Your Fire Pit

Building a cement block fire pit is one of the most affordable and rewarding DIY projects for your backyard. It creates a cozy space where friends and family can gather. But before you start stacking blocks, it’s important to know which materials will work best. The right cement blocks can make your fire pit safer, sturdier, and longer-lasting.

Types of Cement Blocks You Can Use

There are several types of cement blocks available at hardware stores. Each has its own advantages depending on your fire pit design, budget, and safety concerns.

Cinder blocks are among the most popular cement block fire pit choices. They’re lightweight, easy to work with, and inexpensive. However, not all cinder blocks are created equal. Standard cinder blocks are made with concrete and coal cinders. Some of them are hollow, which can cause problems when exposed to high heat. If you choose cinder blocks, go for solid ones or those labeled as high-density. Hollow cinder blocks can trap moisture inside, which may cause them to crack or even explode when heated.

Concrete blocks are another strong option. They are made entirely of concrete and offer greater density than cinder blocks. These blocks can withstand higher temperatures. Solid concrete blocks are often a better choice if you plan to use your fire pit frequently. They’re heavier and more durable, making them ideal for a permanent cement block fire pit.

Landscaping blocks, sometimes called retaining wall blocks, are a great choice for a more decorative look. These are typically designed with curved edges or patterns and can add style to your fire pit. While they are mostly used for walls and borders, many are heat-resistant enough for a fire pit structure. Make sure the ones you choose don’t have internal voids where moisture can collect.

Heat Resistance and Safety Considerations

Heat resistance is one of the most important factors when choosing blocks for a cement block fire pit. You need materials that can handle repeated exposure to high temperatures without degrading. Some cement blocks are designed specifically for retaining walls or garden borders, but they may not withstand direct heat from an open flame. Look for blocks that are rated for fire features or ask at your local home improvement store.

Another way to boost the safety and longevity of your fire pit is by lining the inside with fire bricks. Fire bricks are designed to withstand extreme heat. They’ll protect the cement blocks from heat damage and extend the life of your fire pit.

Shape and Size of the Blocks

Consider the size and shape of the cement blocks. Larger blocks are ideal for building a wide and stable base. Smaller landscaping blocks work well for creating a more refined top layer. Mixing different sizes can give your cement block fire pit a custom look while keeping it functional.

Choosing the Right Block Makes a Difference

The cement blocks you choose for your fire pit will directly impact its durability and safety. A well-built cement block fire pit, made from the right materials, can provide years of enjoyment. Whether you want a rustic, simple design or a sleek, polished look, selecting the best blocks is the first step toward building a fire pit you’ll be proud of.

Adding a Grate or Cooking Surface to Your Cement Block Fire Pit

A cement block fire pit is great for warmth and ambiance, but adding a cooking surface can make it even more useful. With a simple grate or grill, you can turn your backyard fire pit into a place for casual outdoor cooking. Grilling over an open flame brings out flavors you just can’t get from a kitchen stove. It also adds a fun and social element to your gatherings.

Why Add a Cooking Surface to Your Fire Pit?

A cooking surface gives your cement block fire pit more versatility. You can use it for roasting marshmallows, grilling burgers, or cooking a full meal. It’s a simple upgrade that makes the fire pit a centerpiece for outdoor entertaining. If you’re already gathering friends around the fire, adding a grill gives everyone a reason to stay a little longer.

Types of Grates and Cooking Surfaces You Can Use

There are several options for cooking over a cement block fire pit. The simplest is a standard metal grate. These are available in many sizes, so you can easily find one that fits the shape of your fire pit. Look for a grate made from stainless steel or cast iron. Stainless steel grates resist rust and are lightweight. Cast iron grates retain heat well and give excellent grill marks, but they need seasoning and care to prevent rust.

For more flexibility, you can use an adjustable campfire grill. These often come with legs or stakes that allow you to set the height above the fire. Being able to adjust the height makes it easier to control cooking temperature. If you like to cook over coals rather than flames, this type of grill is a good choice.

You can also install a swivel grill arm. This is a metal arm attached to a stake driven into the ground next to your cement block fire pit. The grill swings over the fire when you’re ready to cook and away from it when you’re done. It’s a practical option if you want to keep your fire pit clear when it’s not being used for food.

How to Add a Grate to Your Cement Block Fire Pit

Adding a grate is easy. First, measure the inside diameter or width of your fire pit. Buy a grate that rests securely on the edges of the blocks. Some people use rebar or metal rods across the pit to support the grate. Place them evenly on opposite sides of the fire pit and rest the grate on top. Make sure it’s stable and can handle the weight of food and cookware.

If you’re using a campfire grill with legs, you won’t need support rods. Just place it over the center of the fire pit, adjusting the height as needed.

Safety Tips for Cooking Over Your Fire Pit

Before cooking, make sure your cement block fire pit is built with heat-resistant materials. Some blocks may crack under high temperatures. Keep a fire extinguisher or water source nearby just in case. Use long-handled tools and heat-resistant gloves for safety. Don’t leave food unattended over the fire.

Adding a grate or cooking surface turns your cement block fire pit into a multi-purpose backyard feature. Whether you’re grilling dinner or just toasting marshmallows, it brings more enjoyment to your outdoor space. With the right equipment, your fire pit can offer warmth, ambiance, and great food.
