How long do concrete gas fire pits last?

With proper care, a quality concrete or GFRC fire pit can last for many years. Concrete stands up to sun, rain, and temperature swings, and GFRC adds strength while keeping the weight down. Sealing the surface as the manufacturer recommends, keeping the burner clean, and using a cover between uses all help it last longer.

Will a concrete fire pit crack?

Fine hairline cracks and color variation are natural characteristics of concrete and don't affect how the fire pit performs. Larger cracks are usually caused by moisture. If water soaks into the concrete and then freezes or heats up quickly, it can expand and damage the surface. Keep your fire pit covered, let it dry out before lighting it after heavy rain, and choose a model made from GFRC or another concrete engineered for outdoor fire features.

Can I put a concrete fire pit on a deck?

Sometimes, but check carefully first. Concrete fire pits are heavy, even when they're made from lighter GFRC. Confirm that the manufacturer allows deck installation, check the product's total weight, and make sure your deck can support that weight in one spot. If you're not sure, have a contractor check the deck framing. A lighter GFRC or aluminum fire pit may be a better fit for decks and rooftops.

Do concrete fire pits need to be sealed?

Most do. Concrete is porous, so a sealer helps protect it from stains, moisture, and fading. Many concrete fire pits come sealed from the factory, and manufacturers usually recommend resealing periodically. Follow the care instructions for your model, and use a sealer that's approved for concrete exposed to heat.

Can I build my own concrete fire pit?

Casting a concrete fire pit from scratch is a complex project. The mix, curing, burner fit, and ventilation all have to be right for the fire pit to be safe and last. If you want a custom look, a ready-to-finish fire pit is a simpler option: it gives you a pre-built, fire-rated frame with room for the burner and ventilation, and you finish the outside with stone, stucco, or tile.

What accessories do I need for a concrete gas fire pit?

Every gas fire pit needs fire media, such as lava rock, fire glass, or fire balls, to cover the burner and spread the flame evenly. A glass wind guard keeps the flame steady on breezy nights, and a soft cover protects the concrete and burner from weather between uses. If your fire pit runs on propane with the tank outside the base, a matching propane tank cover hides the tank and doubles as a side table.

Concrete Gas Fire Pits

Concrete fire pits bring a handcrafted, architectural look to any outdoor space. Shop concrete and GFRC gas fire pits, fire pit tables, and fire bowls in a range of colors, textures, and shapes, built for propane or natural gas and made to stand up to the weather year after year.

Why Choose a Concrete Fire Pit?

Concrete is durable, weather resistant, and naturally heavy, so a concrete fire pit stays put and holds up to sun, rain, and temperature swings. Each piece has subtle variations in color and texture that give it a natural, one-of-a-kind look. Concrete complements modern, transitional, and rustic outdoor designs alike.

What Is GFRC?

GFRC stands for glass fiber reinforced concrete. It's concrete reinforced with glass fibers instead of steel, which makes it strong while keeping it much thinner and lighter than traditional solid concrete. GFRC lets manufacturers create sleek shapes and thin edges that wouldn't be possible with standard concrete, and it's easier to place on patios and decks.

Weight and Placement

Even with GFRC, concrete fire pits are heavy. Before you order, check the product weight and make sure your patio, deck, or rooftop can support it. Plan how it will be delivered and moved into place, and set it on a stable, level surface.

Styles of Concrete Fire Pits

Concrete fire pits come in several styles. Fire pit tables have a wide ledge for drinks and plates, fire bowls offer a sculptural focal point, and fire and water features combine flame with spilling water. Choose round, square, or rectangular shapes to match your seating and patio layout.

Caring for Concrete

Concrete is low maintenance, but it is porous. Many manufacturers recommend periodic sealing to protect the surface from stains and moisture, so follow the care instructions for your model. Clean with mild soap and water rather than harsh chemicals, and use a soft cover between uses to keep the surface clean and dry. Small hairline cracks and color variation are natural characteristics of concrete and don't affect performance.
