When it comes to designing outdoor spaces, fire pits, and fireplaces have become increasingly popular features. They add warmth, ambiance, and a focal point for gatherings. One common question that arises in the planning stages of these features is whether pavers can be used as fire bricks.
To answer this question, it’s important to understand the differences between pavers and fire bricks, the materials they are made from, and the environments they are designed to withstand. And that’s precisely what we want to discuss in this article.
We will explore these aspects in detail to help you decide on your outdoor project – besides answering if pavers can be used as fire bricks, we want to give you some alternatives for it. Let’s get right to it, then!

Can pavers be used as fire bricks: pavers vs. fire bricks
So, can pavers be used as fire bricks? Well, not really.
For a full explanation of such a matter, you must first understand the differences between pavers and firebricks.
See, pavers are generally used for walkways, patios, and driveways. They are typically made from materials like concrete, brick, and natural stone, which are designed to be durable and withstand various weather conditions, including rain, snow, and sunlight. However, their primary purpose is not to endure extreme heat.
Fire bricks, on the other hand, are specifically designed to withstand high temperatures. They are commonly used to line fireplaces, fire pits, and kilns. Made from fire clay or refractory ceramic materials, fire bricks can endure temperatures as high as 1,800 degrees Fahrenheit or more without breaking down or deteriorating.
So, while pavers and fire bricks may look similar, they are not interchangeable. The most crucial difference between pavers and fire bricks is their ability to withstand heat. Fire bricks are manufactured to endure high temperatures without cracking or deteriorating.
Pavers, however, are not made to resist extreme heat. When exposed to the intense heat of a fire pit or fireplace, pavers can crack, or even explode due to the rapid expansion and contraction of the materials.
Another difference is that pavers are often made from concrete or standard clay, which does not have the same thermal properties as fire bricks.
Concrete, for instance, is susceptible to thermal shock when exposed to high temperatures, leading to cracking and potential failure. By contrast, fire bricks are made from refractory materials that can withstand the thermal stress of high heat.
Correct uses of pavers around fire features
Using pavers in place of fire bricks in a fire pit or fireplace can be hazardous. But while not suitable for direct use as fire bricks, they can still be used effectively in designing outdoor fire features.
However, this needs to be done very carefully. As mentioned earlier, pavers can crack or explode under high heat. This not only poses a risk of injury from flying debris but also compromises the structural integrity of the fire pit or fireplace.
Even if pavers do not immediately crack or explode, their lifespan is significantly reduced when exposed to high heat. Over time, the constant expansion and contraction caused by repeated heating and cooling will weaken the pavers, leading to deterioration and the need for replacement sooner than if fire bricks were used.
Here are some appropriate uses for pavers in conjunction with fire pits and fireplaces:
- Surrounding area
Pavers can be used to create a decorative and functional surface around a fire pit or fireplace. They provide a stable and attractive surface for seating areas and help define the space, creating a safe and visually appealing environment. - Fire pit base
If a fire pit is constructed with a metal or stone inner ring, pavers can be used as a base to provide stability and aesthetics. The metal or stone ring will contain the heat, preventing it from directly affecting the pavers. - Outdoor kitchens and grills
Pavers are excellent for use in outdoor kitchens and around grills, where they will not be exposed to the direct flames or high temperatures of a fire pit or fireplace. They provide a durable and attractive surface that can handle the spills and stains associated with cooking.

Fire brick alternatives
If you are looking to build a fire pit or fireplace and are considering alternatives to fire bricks, you have a few available in the market.
The first one is refractory concrete, which is a special type of concrete designed to withstand high temperatures. It can be molded into various shapes and sizes, making it versatile for fire pit construction.
Certain types of natural stone, like granite and basalt, can withstand high temperatures and are often used in fire pit construction, being another good alternative for fire bricks. However, it’s important to ensure the stone is heat-resistant and suitable for use with fire.
And finally, metal fire rings are a popular choice for lining the interior of a fire pit. They provide a barrier that protects the surrounding materials from direct exposure to heat.
Can pavers be used as fire bricks?
To summarize, no, they cannot.
While pavers are a versatile and durable material for many outdoor applications, they are not suitable for use as fire bricks. Fire bricks are specifically designed to withstand the high temperatures generated by fire pits and fireplaces, ensuring safety and longevity.
