What do you put in the bottom of a firepit?
The bottom of your fire pit should contain a few inches of gravel or lava rocks. These materials are inflammable and provide stability, heat protection, and drainage. Adding sand on top can further insulate the pit and help distribute heat. Putting gravel on the ground around your fire pit creates a nice, level base for seating. Plus, it protects the ground and surrounding area with a non-flammable material in case any embers make their way out of the fire pit.What Does Sand Do For a Firepit? Placing an even amount of sand towards the bottom of your fire pit will create an entire layer of additional heat protection. Sand can act as a buffer between the wood or fuel you use in your fire and the bottom of your firepit, preventing it from burning or charring over time.You can dig a hole for a firepit almost anywhere you want, but you need to ensure they out in the open, far away from buildings, trees or anything else that may catch fire. It’s also important to dig your pit in sand, not gravel, where possible.Lay Out the Fire Pit Lay out your first layer of blocks on top of the level gravel base. Be sure the sides of the blocks are touching. Place the blocks one-by-one around the perimeter of the hole, pushing them together and using a level to make sure the height stays consistent.
Is a DIY fire pit safe?
If you are looking to purchase or build a portable fire pit it should be designed with a heavy base. Added sand to the bottom can prevent overheating and can maintain stability. Fire pits should always be placed 10 feet from any structure, away from dry grass/foliage, and close to a water source. A strong foundation gives you confidence that your fire pit will stay safe, level, and looking great for years to come. That’s why we recommend starting with a 3″ layer of compacted ¾” minus gravel. This gravel includes fine particles that lock together when compacted, creating a strong and well-draining base.Keep the fire pit away from siding, decks, deck railings, tents, grass or other vegetation, and out from under eaves, overhanging branches, or overhanging rooflines. Use a fire pit screen to help contain sparks, embers, and ash. In wood-burning pits, burn only clean, dry, seasoned hardwood.The bottom of your fire pit should contain a few inches of gravel or lava rocks. These materials are inflammable and provide stability, heat protection, and drainage. Adding sand on top can further insulate the pit and help distribute heat.Fire pits should be placed at least 10 feet away from your home, other structures or anything combustible. Don’t set up fire pits under string lights or power lines. Use a fire-proof base for your unit, especially on a wood deck. Follow no-burn alerts and avoid starting a fire in windy conditions.
What wood should you not burn in a fire pit?
Painted or Treated Wood If the wood you intend to burn has been painted or treated in any way, then this should also be avoided burning on your fire pit. Paints and wood treatments may give off toxic fumes when burned. Avoid burning plywood, particle board, or other engineered woods in your fire pit. These materials often contain adhesives and resins that release toxic fumes when burned. The smoke from these can irritate your eyes and lungs, potentially causing long-term health issues.
What’s the best thing to use for a fire pit?
You’ll need to construct the interior of the fire pit with fire-resistant materials, so fire bricks, which are designed to stand up to direct fire, are a must. The exterior of the ring doesn’t need to be fire-resistant, but it does need to be heat-resistant. Regular retaining wall blocks are OK to use. Regular bricks can work for the exterior fire pit walls, but they are not suitable for the interior lining. Standard bricks contain moisture and may have air pockets that expand when heated, which can cause them to crack or even explode when exposed to direct flames.Clay Bricks: Choose fire-rated clay bricks, which can withstand high temperatures. Common red clay bricks work well for this project. Fire Pit Insert or Grate: This is optional but highly recommended, as it helps improve airflow and ensures the fire burns more efficiently.
Why put rocks in the bottom of a fire pit?
Gravel and Crushed Rocks Why put gravel in the bottom of a fire pit? Gravel and other gravel-based materials enhance stability and ensure proper drainage.

What is the best base for a DIY fire pit?
For improved airflow and drainage, pea gravel or crushed stones like lava rocks make ideal fire pit bases. Use smooth pebbles around 1/4 to 1/2 inch in diameter. Install at least a 6-inch layer and tamp down to compact. Refractory cement can help hold rounded rocks in place. There’s a variety of fire media available, from traditional lava rock to contemporary fire glass and rustic log sets. Pro Tip: DO NOT use regular stones or river rocks in your gas fire pit. Regular stones may contain water that, once heated, will produce a build-up of steam, and cause the stones to explode.
