Don’t put sand in it! It just holds any moisture that may get in. Drill holes in the bottom and line bottom with chunks of fire brick or lava rock. I’ve had mine for about 12 years and am just now replacing it with the same fire pit.
Can sand explode in fire pit?
Some materials like hard rock, gravel, or sand weren’t meant to reach high temperatures and can spark and explode if your fire gets too hot. Instead, use lava rocks for your fire pit or lava glass beads as a filler for your fire pit.
Is sand heat resistant?
The materials of clay, cement, lime and sand are naturally resistant to fire and heat.
Why is there a hole in the bottom of my fire pit?
The simple answer – All fire pits should have holes to permit airflow to the flames. Without oxygen flowing to the fire, it won’t burn much at all. So, for a lovely, bright, and safe flame, holes clear of debris are necessary.
