Do concrete gas fire pits crack in cold weather?

While standard concrete is susceptible to cracking, our Glass Fiber Reinforced Concrete (GFRC) units are engineered to handle extreme temperature fluctuations. To prevent non-structural surface fissures, always use a protective cover during winter months to keep moisture from entering the burner area and freezing, which is the primary cause of material stress.

Can I put a concrete fire pit on a wood deck?

Usually yes, but it can vary based on local code. Typically it is allowed but be sure to check with the authorities having jurisdiction in your area. You must verify the load-bearing capacity of your deck and use a heat-resistant barrier, as well. GFRC is lighter than solid concrete, but a large fire table can still weigh 300 plus pounds. Most models feature an elevated burner pan that provides an air gap, keeping the bottom of the unit cool enough for safe deck placement.

Does a concrete fire pit hide the propane tank?

Many of our rectangular and square fire tables are designed with a hollow base specifically to conceal a standard 20-pound propane tank. If you choose a low-profile fire bowl, the tank must be stored externally. We offer matching concrete tank covers that can double as a side table or stool to maintain a cohesive aesthetic.

The Comprehensive Guide To GFRC Concrete Fire Pits

Why Choose A GFRC Concrete Fire Pit?

Glass Fiber Reinforced Concrete (GFRC) represents the pinnacle of modern hearth engineering. It provides the massive, permanent look of traditional stone without the excessive weight or vulnerability to moisture. For the professional designer and contractor, these fire features offer:

Thermal Resilience: The integration of glass fibers allows the concrete to expand and contract during high-heat cycles without the structural failure often seen in standard pre-cast units.
Artisanal Finishes: Every pit is hand-cast and finished with specialized patinas that mimic natural stone, weathered metal, or smooth industrial cement, ensuring no two units are identical.
Integrated Functionality: Many models are designed as "fire tables," providing a functional surface for cocktails or small plates, which maximizes the utility of limited patio square footage.

How To Choose The Perfect Concrete Fire Feature

Material Composition: GFRC vs. Standard Poured Concrete

Standard concrete is heavy, brittle, and prone to "spalling" when exposed to freeze-thaw cycles. We exclusively curate GFRC units because they offer higher flexural strength and a much lower weight-to-size ratio. This makes them safer for installation on reinforced wood decks and easier to position during custom builds.

Fuel Management: Internal vs. External Propane Storage

When selecting a propane model, determine if you need an "Internal Tank" unit. These designs are taller and allow the 20lb propane tank to be hidden inside the concrete base. Smaller, low-profile fire bowls typically require an "External Tank" configuration, where the tank is hidden under a matching side table or connected via an underground gas line.

Burner Quality and Heat Output

A luxury concrete vessel is only as good as the burner inside. We recommend matching your GFRC pit with a 304 stainless steel or brass burner system. Brass burners are particularly effective for concrete units as they resist the corrosion caused by trapped moisture and provide a taller, more natural yellow flame.

Maintenance and Surface Protection

Concrete is naturally porous and can be stained by oils or organic debris. To preserve the hand-applied patina, it is essential to use a weather-resistant cover when the pit is not in use. Applying a high-quality concrete sealer once every two seasons will keep the finish vibrant and prevent salt or water penetration.
