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 surface can you put a firepit on?
Patio slabs are the most effective option to use as surfaces for a fire pit. Slabs are very flat and stable, and they will readily absorb any heat conducted or radiated from the fire pit, protecting your lawn from becoming scorched.
What is the best base for a fire pit?
Hard rocks like granite, marble, or slate are much denser, and therefore less likely to absorb water and explode when exposed to heat. Other rocks that are safe to use around and in your fire pit include fire-rate brick, lava glass, lava rocks, and poured concrete.
How do you prepare a ground for a fire pit?
Place your stone in piles around your fire pit location. Divide the stone into a pile for each type of stone, a pile for capstones, and a pile for firebrick. Leave a 1-1/2 to 2-foot space for you to work between the edge of your wall and the piles of stone, as well as space in between each pile for your wheelbarrow.
