Whether you’re doing it yourself or hiring a pro, you’ll find everything you need here.

Key Takeaways

• Choose the right size and location, keeping safety regulations in mind.
• Gather essential tools and materials like a pickaxe, shovel, and gravel.
• Ensure safety by controlling open flames, checking wind patterns, and proper ash disposal.

Why Choose an In-Ground Fire Pit?

In-ground fire pits offer several benefits:

• Better containment of flames
• Lower cost of installation
• Reduced risk of fire spreading

When deciding between a DIY project and hiring a professional, consider your skill set and budget. DIY can be rewarding and cost-saving but requires effort and tools. Professional installation ensures precision and safety but costs more.

Choosing the Perfect Location

Selecting the perfect spot for your fire pit is crucial for both safety and enjoyment.

• Ensure the fire pit is at least 10 feet away from your house, neighbors’ yards, and any flammable structures.
• Check local wind patterns to prevent smoke from becoming a nuisance.
• Choose a location free of overhead obstructions like trees or pergolas to avoid fire hazards.
• Think about seating arrangements and ensure there’s enough space for everyone to sit comfortably around the fire.

Essential Tools and Materials

Before you start digging, gather all the essential tools and materials.

Tools you'll need:

• Pickaxe for marking the perimeter and breaking hard ground.
• Flathead shovel for digging and leveling the bottom of the fire pit hole.
• Small garden shovel for adjusting dirt levels and ensuring you don’t leave gaps.
• Small brush to clean off excess dirt.
• Heavy-duty construction adhesive (4 tubes).
• Caulking gun for applying the adhesive.
• Level to ensure the base layer of stones is flat and even.

Materials required:

• Gravel for drainage.
• Fire-resistant bricks or stones.

Step-by-Step Installation Guide

1. Mark and Dig

• Use the 811 service to locate underground utilities before you begin digging.
• Mark the outline of your fire pit using stakes and a string for accuracy. This will help you visualize the size and shape of the pit.
• Begin digging the hole manually with a shovel or use a digger to save time and effort. Ensure that the hole is a few inches deeper than the height of one stone to allow for proper drainage.

2. Add Gravel

• Add a layer of gravel at the bottom for drainage. This step is crucial to prevent water accumulation and ensure a sturdy base.
• Ensure the base is level by using a spirit level.

3. Place and Secure Stones

• Once you’ve ensured that the hole is deep enough and the base is level, begin placing your blocks inside to check their depth and diameter.
• Apply construction adhesive to the bottom of a block and stack it on top of the first layer.
• Continue gluing and stacking the remaining stones, ensuring each layer is level and aligned. Stagger each course of stones from the one below for added stability.

4. Backfill and Compact

• Backfill behind the walls with gravel for stability.
• Lay landscaping fabric between the backfilling and recompacted topsoil to prevent soil from slipping into the gravel.
• Pour limestone screenings around the edge before compacting.
• Use a tamper tool to firmly compact the backfilled material around the fire pit. This step is crucial to prevent the structure from shifting over time.

Ensuring Proper Depth and Diameter

Ideal dimensions:

• Depth: 6 to 12 inches.
• Diameter: 36 to 44 inches.

Adjust the dimensions based on the size of your gatherings—smaller pits for intimate settings, larger diameters for bigger parties.

Adding Finishing Touches

Consider adding seating options like:

• DIY wood benches
• Concrete benches
• Adirondack chairs

These options provide both comfort and style to your fire pit area, ensuring an enjoyable experience. Adding a fire pit ring inside the base layer offers extra protection and longevity.

Safety Considerations

Safety Tips:

• Control flames and embers to prevent accidental fires.
• Keep children and pets at least 3 feet away from the fire.
• Check wind direction before lighting a fire to prevent uncontrollable spreading.
• Avoid using flammable fluids like gasoline or lighter fluid to light or relight fires.
• Burn only dry firewood to avoid toxic fumes and chemical damage.
• Ensure proper disposal of ashes by placing them in a metal container and pouring water on them after they have cooled.

Maintenance Tips for Longevity

Proper maintenance ensures your fire pit lasts for years and remains safe.

Maintenance steps:

• Cover the fire pit when not in use to prevent rain or snow accumulation and keep out animals.
• Let fires extinguish naturally to avoid rapid temperature drops that can crack the pit.
• Use only dry firewood to maintain the fire pit’s condition and reduce the risk of damage.

Regular maintenance will keep your fire pit looking great and functioning safely for many enjoyable evenings.

Alternatives to Building Your Own Fire Pit
