What’s the Safest Surface for a Fire Pit or Fire Table?

Installing a fire pit is one of the best upgrades you can make to your outdoor space—but it’s not just about choosing a great-looking model. The surface beneath your fire feature plays a critical role in safety, stability, and long-term performance.

In this guide, we’ll break down the best surfaces to use, which ones to avoid (or protect), and what to do if you have a composite deck or wood patio.

Best Surfaces for Fire Features

• Concrete: One of the most heat-resistant and stable bases available. Ideal for permanent installations or patio builds.
• Natural Stone or Pavers: Stylish, durable, and capable of withstanding radiant heat from gas burners.
• Gravel or Decomposed Granite: A great option for fire bowls or freestanding pits. It also allows for drainage and a natural look.
• Outdoor-Rated Tile: Effective when paired with a proper sub-base and level surface.

Surfaces That Require Extra Caution

Not all backyard surfaces are fire-feature-ready. Here's how to handle the most common challenges:

Composite Decking

Composite decking is attractive and durable—but most brands are not rated for high radiant heat exposure. Direct placement of a fire pit or table can cause warping, discoloration, or pose a fire hazard.

If you have composite decking:

• Choose a fire table with a built-in bottom heat shield or pedestal base
• Add a non-combustible heat barrier (like a fire pit pad or concrete board underneath)
• Stick with gas-burning units (wood-burning is not recommended)

Wood Decks

Wood is combustible and more vulnerable to heat damage. Use extreme caution:

• Always place a certified fire-resistant pad underneath
• Maintain clearance from railings, walls, and furnishings
• Consult local fire codes and the fire feature’s manufacturer guidelines

Grass, Dirt, or Bare Ground

These are the least stable and most hazardous surfaces. Fire pits can tip, sink, or ignite surrounding material. If bare ground is your only option:

• Level the area
• Use a non-combustible base or platform

Fire Features Under Covered Patios or Pergolas

Yes, you can place fire features under structures—but only with rated models and proper clearance. Consider the following:

• Use gas fire pits only (never wood-burning under a roof)
• Ensure the structure meets the product's vertical clearance requirements (typically 6–10 ft)
• Ensure there is sufficient ventilation, especially for propane or natural gas

Final Thoughts

The safest way to enjoy your fire pit or fire table is by installing it on the right surface and using protective accessories when needed. Whether your space is concrete, composite, or covered, there's a setup that’s safe, functional, and beautiful.
