Why are my fire pit rocks popping?

Q: Why is my fire pit popping? If the lava rocks in your fire pit are popping, they have water trapped inside. This water is turning to steam, expanding and blowing open the rocks. If this is happening you should stand back from the fire pit for 15 minutes until all the lava rock has cured or dried out.

How long do lava rocks last in a fire pit?

Lava rocks should last for around two years before they start to show signs of wear. Keep using them in your fire pit until you notice them getting a little crumbly looking.

How do you stop lava rocks from popping?

Let the fire pit burn for at least 10 minutes on high while standing away from it. This will dry out the lava rocks. If the lava rocks start exploding you should continue heating them on high heat until they stop. If the rocks haven’t been cured before it may take up to 45 minutes to completely dry out the rocks.
