Permanent fire pits have heat proofing built in, but freestanding models need to sit on a fire ring, cement pavers, a heat shield, or a fire-retardant mat to protect the patio or grass. For wood or trex decking, you’ll need a thermal barrier such as DeckProtect™ to ensure you don’t cause damage.

What is the best base for a fire pit?

What should I put around my fire pit?
Cover the landscape fabric or plastic with a non-flammable material of your choice, such as river rocks, gravel, brick or stone pavers.
