Planning Your BBQ Pit: The Foundation for Success

Before you start gathering materials and tools, careful planning is crucial. Here are the key factors to consider:

1. Type of BBQ Pit:

There are several types of BBQ pits, each with its own advantages and disadvantages. Here are a few popular options:

• Brick Pit: Durable, classic look, excellent heat retention, but can be more labor-intensive to build.
• Concrete Block Pit: Easier and quicker to assemble than a brick pit, also offers good heat retention.
• Metal Drum Pit: Affordable, readily available, easy to modify, but might not be as durable as masonry pits.
• Smoker/Offset Pit: Features a separate firebox for indirect heat, ideal for low-and-slow smoking.
• Barrel Pit: Similar to a drum pit but specifically uses a food grade metal barrel, ensuring food safety

For this guide, we will focus on building a simple, yet effective, concrete block pit, as it’s a good balance of ease of construction and durability. The principles, however, can be adapted for other materials.

2. Size and Dimensions:

Consider how much food you typically cook and the available space in your backyard. A standard size for a family pit is typically around 3ft wide x 3 ft deep x 3 ft high, but you can adjust to your needs. Think about:

• Cooking Area: Ensure enough surface to accommodate your grills and desired amount of food.
• Firebox Size: A good ratio is approximately 1/3 of the cooking area size.
• Height: Build to a comfortable height for cooking. You should be able to reach the grill grate without straining.
• Storage Space: Consider whether you need space to store wood, charcoal, or cooking tools.

3. Location:

Choose a location that is:

• Well-Ventilated: Smoke needs to be able to disperse safely.
• Away from Flammable Materials: Keep a safe distance from fences, trees, and structures.
• On Level Ground: A stable base is essential for a safe and long-lasting pit.
• Convenient: Close enough for easy access but far enough from your home to minimize smoke intrusion.

4. Materials:

For a concrete block pit, you will need:

• Concrete Blocks: Select blocks that are durable and heat-resistant. Calculate how many you will need based on your pit’s dimensions.
• Mortar Mix: For joining the blocks. Choose a mix appropriate for masonry work.
• Grill Grates: Consider heavy-duty stainless steel or cast iron. The size should match the width and depth of your pit.
• Firebricks (Optional): Can be used to line the firebox for extra heat protection and longevity.
• Gravel or Sand: For a solid foundation.
• Metal Rebar (Optional): For additional structural integrity in the walls.

5. Tools:

• Shovel: For digging and moving materials.
• Level: For ensuring a level foundation and even construction.
• Trowel: For applying mortar.
• Mortar Mixing Tub: For mixing mortar.
• Measuring Tape: For accurate measurements.
• Gloves: For protecting your hands.
• Safety Glasses: To protect your eyes from debris.
• Wheelbarrow (Optional): For moving heavy materials.
• Angle Grinder (Optional): For cutting blocks or rebar.
• Chisel and Hammer (Optional): For shaping blocks.

Step-by-Step Guide: Building Your Concrete Block BBQ Pit

Now that you’ve planned your pit, it’s time to get building. Here’s a detailed step-by-step guide:

Step 1: Prepare the Foundation

1. Clear the Area: Remove any vegetation, rocks, and debris from your chosen location.
2. Mark the Perimeter: Use stakes and string to mark the outer dimensions of your pit. Remember to account for the thickness of the blocks.
3. Excavate: Dig down a few inches (around 4-6) below the surface to create a level base.
4. Lay Gravel or Sand: Pour a layer of gravel or sand into the excavated area. Use a rake or shovel to spread it evenly.
5. Compact the Base: Use a hand tamper or a flat board to compact the gravel or sand. This will create a stable foundation for your pit.
6. Double Check Level: Recheck the level to ensure the base is flat and level. Make adjustments as necessary.

Step 2: Lay the First Course of Blocks

1. Mix Mortar: Following the manufacturer’s instructions, mix a small batch of mortar in the mixing tub. The consistency should be like thick peanut butter.
2. Apply Mortar: Using your trowel, apply a thick bed of mortar along the gravel foundation, aligning with your marked perimeter string.
3. Place Blocks: Place the first block, ensuring it is level with the surrounding mortar. Lightly press into the mortar.
4. Repeat the Process: Continue to apply mortar and lay blocks, checking each one for levelness with the surrounding blocks.
5. Check Alignment: As you lay the first course, use your level to check the alignment of the entire perimeter. Adjust as needed.
6. Add Rebar (Optional): If desired, insert lengths of rebar into the hollow cores of the blocks.
7. Allow Curing: Let the mortar cure for at least 24 hours before continuing with the next course.

Step 3: Lay Subsequent Courses of Blocks

1. Apply Mortar: Apply a bed of mortar to the top of the first course of blocks.
2. Stagger the Joints: Stagger the joints of the second course to provide more strength and stability. A typical layout would be for each block to straddle two blocks on the lower level, similar to brickwork.
3. Lay Blocks: Carefully place the second course of blocks, making sure the joints align with the first course and that each block is level.
4. Continue Layers: Repeat the process of applying mortar, laying blocks, and checking for levelness until you reach the desired height. Usually 3-4 courses is enough for most needs.
5. Add Rebar (Optional): If using, continue to insert rebar into the hollow cores of the blocks as you stack them.

Step 4: Building the Firebox

1. Determine Firebox Dimensions: On the first course, mark where your firebox will be. Typically it will be on one side or the center of your structure.
2. Prepare Firebrick: If using firebricks to line the firebox, cut them using an angle grinder with a masonry cutting blade to the desired size.
3. Apply Mortar: Apply a layer of mortar to the inside of the marked firebox.
4. Install Firebricks: Place the firebricks using mortar, ensuring they are level and are evenly spaced from the concrete blocks. This will protect the blocks from the high heat of the fire.
5. Continue to line the firebox: Continue the process of mortaring and laying the firebrick up to the height you need

Step 5: Prepare the Top and Grill Area

1. Add Top Blocks: For the final course, you can add cap blocks that will overhang the structure providing a better overall finish. Or just lay down your final course like the others.
2. Determine Grill Support: You can lay metal support bars across the opening to support your grill grates. If your pit is very wide, you may need to add supports in the middle too. These can either be mortared in or removable.
3. Ensure Proper Fit: Place the grill grates on top to ensure they are supported correctly and are level. Make adjustments as needed.

Step 6: Cure and Clean the Pit

1. Cure the Mortar: Allow the mortar to cure for at least 48-72 hours, or according to manufacturer instructions. This will allow the mortar to fully harden and provide a solid structure.
2. Clean the Pit: Use a brush or broom to remove any loose mortar, debris, and dust from inside the pit and on the surrounding area.
3. Wash the Pit: Use a hose or water to wash the area down. This will remove any remaining dust.
4. Test Fire: If using fire bricks, cure them slowly to allow them to adapt to heat. Light a small fire and let it burn for a few hours and allow the pit to cool slowly to prevent cracks from forming.

Finishing Touches and Safety Considerations

Finishing Touches

• Painting: You can paint the blocks with high-temperature paint to add some style and protect them from the elements.
• Stone Facing: You can add decorative stone facings to the pit for a more refined and polished look.
• Shelves: Add wooden shelves to provide convenient spots to set down food and cooking tools.
• Storage Compartments: You can add metal or wooden doors to the bottom or sides of your pit, making storage for charcoal or other cooking equipment.

Safety Considerations

• Fire Safety: Always have a fire extinguisher or a water source nearby when using your pit.
• Keep Flammable Materials Clear: Ensure flammable materials are kept at a safe distance.
• Supervise the Fire: Never leave a fire unattended.
• Use Proper Tools: Always use long-handled grilling tools to avoid getting burned.
• Dispose of Ashes Properly: Allow ashes to cool completely before disposing of them. Use a metal container and pour water over them to be sure.
• Be Aware of Local Regulations: Check local fire and building codes before building your pit.
