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. Perfect 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: Great for fire bowls or freestanding pits. Also allows for drainage and a natural look.
• Outdoor-rated tile: Works well when paired with a proper sub-base and level surface.

⚠️ Surfaces That Need Extra Caution

Not all backyard surfaces are fire-feature-ready. Here's how to approach the most common problem areas:

🟤 Composite Decking

Composite decking looks great and lasts long—but most brands are not rated for high radiant heat exposure. Direct placement of a fire pit or table can lead to warping, discoloration, or even fire risk.

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 surfaces are combustible and prone to heat damage. If you're placing a fire pit here, use extreme caution:

• Use a certified fire-resistant pad underneath
• Keep clearance to railings, walls, and furniture
• Check local fire codes and manufacturer specs

🌱 Grass, Dirt, or Bare Ground

These are the least stable and most hazardous surfaces. Fire pits can tip, sink, or ignite surrounding material. If you must install on bare ground, level it first and use a non-combustible base or platform.

🏠 What About Covered Patios or Pergolas?

Yes, you can place fire features under structures—but only certain models and only with proper clearance. Key factors to consider:

• Use gas fire pits only (never wood-burning under a roof)
• Ensure vertical clearance matches the product's safety rating (often 6–10 ft)
• Ventilation must be adequate—especially for propane and natural gas
