Fire Pit Dilemma: Is Lava Rock or Gravel the Better Choice?

When it comes to creating the perfect fire pit, choosing the right materials is crucial for not only aesthetic appeal but also safety. One common question is whether to use lava rock or gravel for a fire pit. Here’s what you need to know:
  • If you’re burning wood in your fire pit, it’s recommended to put at least 4-5 inches of lava rock at the bottom. This will help with air circulation and keep the fire going.
  • For gas fires, make sure to completely cover the fire rings with lava rock. This will add a decorative touch while helping to distribute the heat more evenly.
  • It’s important not to use rocks or any type of gravel in place of the lava rock. This is because rocks or gravel can potentially explode when heated.
Overall, if you are looking to safely and effectively create your perfect fire pit, it’s best to stick with lava rock rather than gravel or other alternatives.

Understanding Fire Pit Safety

Having a fire pit in your backyard can be an amazing addition to your home, providing warmth and a cozy ambiance for you and your guests. However, it’s important to maintain proper safety precautions to avoid any potential hazards.

The Importance of Proper Lava Rock Depth

One of the most important considerations for safe fire pit use involves the depth of the lava rock. When burning wood, it’s essential to put the lava rock at least 4-5 inches in depth. This prevents the flames from getting too close to the bottom of the fire pit, which could potentially cause the pit to overheat and become damaged.

Using Lava Rock for Wood Burning Fires

For wood burning fires, it’s recommended to place your firewood directly on top of the lava stone. This helps to prevent the fire from spreading too quickly and allows for a more consistent burn. Additionally, using lava rock can help to absorb excess moisture, making it easier to get your fire started. When adding new wood to your fire, it’s important to first check that the previous logs have fully burnt down and that there are no remaining hot spots. This will help to prevent accidental fires from occurring.

The Correct Way to Use Lava Rock for Gas Fires

When it comes to gas fires, it’s essential to fill the pit with lava rock to completely cover the fire rings. This helps to distribute the heat more evenly and prevents hot spots from developing. Be sure to check the manufacturer’s instructions for the recommended amount of lava rock to use for your specific fire pit.

Avoiding Gravel or Rock Substitutes for Lava Rock

While some may be tempted to use rocks or other types of gravel in place of lava rock, this poses a significant hazard. Due to their makeup, some rocks or gravel could potentially explode if heated, causing significant damage or injury. Lava rock, on the other hand, is specifically designed to withstand high temperatures and is safe for use in fire pits.

How to Add Lava Rock to Your Fire Pit

Adding lava rock to your fire pit is a relatively simple process. Begin by removing any remaining debris from the pit and cleaning it thoroughly. Next, cover the bottom of the pit with a generous layer of lava rock, making sure to spread it evenly. For gas fires, fill the remaining space with additional lava rock until the fire rings are completely covered. Important Note: Before using your newly-filled fire pit, be sure to turn on the gas and check that all the connections are secure. Ignite the gas and check that the flames are distributed evenly around the fire rings.

Maintaining Your Lava Rock Fire Pit for Safety

Keeping your fire pit maintained is essential for safety and longevity. After each use, remove any remaining debris, such as ashes or wood chips. For gas fires, also be sure to regularly check the fuel supply and replace any empty tanks promptly. If the lava rock becomes worn down or discolored over time, it may be time to replace it. Simply remove the old rock and replace it with new lava rock, making sure to follow the above guidelines for proper usage and depth. By following these guidelines for the appropriate use of lava rock, you can safely enjoy your fire pit for years to come.
