How to Use Lava Rocks for a Fire Pit?
Here's some help for you:
Not a how to comment but if you plan on building a gas fire pit, be careful to avoid moisture. Cover the rocks when not in use to avoid rain saturation.
Before you begin any fire pit project check first with your municipality/county office to learn what they bylaws my be regarding fire pits on your particular property. Many areas now do not permit them any more due to the fire hazard they may pose.
Hi Rachel: Are you talking about those little rocks? You really can't build anything with them, but you can use them as a base for a fire pit. Hope this helps.
Hi! How big are the rocks? Plan on a level top so a screen or grate is on top. Are you planning on digging into the ground? Check local regulations. Where I live a mesh screen must cover the fire to prevent it from spreading or you pay a substantial fine. Good luck and stay safe!
Hi Rachel, hope this will help you build your fire pit. We suggest an inch layer of sand or pea gravel on the bottom of the fire pit for a sturdy foundation. Next, take your lava rocks and place around the fire pit and burner so it fills just enough rock to cover the burner. You are now ready to lite your firepit.
