When it comes to designing outdoor spaces, safety is always a paramount concern. One crucial aspect to consider is the fire resistance of hardscaping materials – and given the popularity of pavers, these products are no exception. Fireproof materials are essential for maintaining the integrity of your outdoor living area and minimizing potential fire hazards. But are pavers fireproof, after all?

In this article, we will delve into this pivotal question, shedding some light on which paving stones share the best heat resistance.

So, Are Pavers Fireproof?

Fireproof hardscaping materials are designed to withstand high temperatures and resist combustion, making them less susceptible to spreading fire. These materials are specifically engineered to slow down the progress of flames, minimize heat transfer, and prevent the fire from rapidly spreading. In any American neighborhood, such risks are better avoided. 

But which pavers do this with excellence? Well, most of them can be mentioned here, but we’ve listed the main ones below.

Concrete pavers

Concrete pavers, in general, have good fire resistance properties. They are made from a mixture of cement, aggregates, and additives, resulting in a solid and durable material. Concrete itself is non-combustible, which means it does not support the spread of fire.

However, it’s important to note that concrete pavers can vary depending on their specific composition and manufacturing process. Some concrete pavers may contain organic additives or coatings that can affect this capability – therefore, it is recommended to choose concrete pavers that are specifically designed and labeled as fire-resistant or fireproof.

Porcelain pavers

Porcelain pavers are known for their durability, aesthetic appeal, and low maintenance requirements. In terms of fire resistance, porcelain is generally considered to be immune, given that it is fired at extremely high temperatures in the manufacturing process, resulting in a dense and non-combustible product.

Porcelain has a high resistance to heat overall, making it less susceptible to damage from high temperatures. As such, they do not contribute to the spread of fire and can act as a protective layer in outdoor spaces.

Brick pavers

Brick pavers are renowned for their exceptional fire resistance among the various hardscaping materials available. They are inherently non-combustible due to its composition, making it an ideal choice for outdoor areas where fire safety is a concern.

Brick pavers are made from clay or shale that undergoes a firing process, resulting in a dense and durable material. The intense heat used in the firing process eliminates organic matter, leaving behind a solid structure that does not support combustion. As a result, brick pavers do not contribute to the spread of fire and help maintain the overall safety of your outdoor space.

What extra safety measures can be undertaken? 

Apart from choosing the best paving stone, choosing the joints between each unit – which are typically filled with sand or mortar – is also crucial to further impede the spread of fire. These joints act as barriers, restricting the movement of flames and preventing them from reaching the underlying layers in case there is a fire. This construction method enhances the resistance of any paver surface, adding an extra layer of protection to your project.

• Polymeric sand is a joint-filling material that consists of a mixture of fine sand and a polymer binder. When water-activated, the polymer binder creates a solid and durable bond, locking the pavers together and acting as a fire barrier due to its composition and ability to harden when dry. During a fire, it undergoes a phase change and solidifies, which helps restrict the passage of flames and prevents the fire from spreading through the joints. Polymeric sand also offers additional benefits, such as weed prevention and increased stability of the paver installation, as you can read in this detailed article.

• Fire-Rated mortar is a specialized type of mortar that is designed to have enhanced fire resistance. It is typically used for joint filling in construction applications, including paver installations where fire safety is a concern. Mortar contains fire-resistant additives that enhance its ability to withstand high temperatures and prevent the spread of fire. When applied between the pavers, it forms a solid barrier that helps protect the underlying layers.

It is important to note that the specific joint filling material used may depend on the type of pavers, the intended application, and local building codes or regulations. As hardscape pros, we advise you to consult with a professional installer or contractor to determine the most suitable joint filling material for your specific project, ensuring compliance with fire safety standards.

Are pavers fireproof when it comes to fire pits?

Fire pits are a popular addition to outdoor living areas, providing warmth, ambiance, and a gathering space for friends and family. And, of course, when incorporating a fire pit into your hardscaping design, it’s crucial to consider fire resistance above all.

You see, using fire-resistant pavers within and around the fire pit area can significantly enhance safety. Bricks, in this sense, with their non-combustible nature, are an excellent choice for constructing its base and surroundings. They act as a reliable barrier, preventing sparks and embers from reaching flammable materials nearby.

That said, to further enhance fire resistance, you must invest in fire-rated materials for the fire pit itself, such as fire bricks or refractory bricks. These specialized materials (stone caps included) are designed to withstand extremely high temperatures without cracking or deteriorating, making them a safe choice for containing the hearth.
