Establishing a stable and suitable base for your fire pit on pavers is crucial for ensuring safety, longevity, and proper drainage. Selecting the appropriate base material depends on factors such as drainage requirements, heat resistance, and availability in your area.

Commonly used base materials include:


Sand offers excellent drainage, making it a suitable choice for areas with high rainfall or poor soil conditions. However, it may require periodic replenishment due to wind or water erosion.


Gravel provides good drainage and heat resistance, making it a versatile option. It is relatively easy to work with and can withstand high temperatures.

Crushed Stone, What to put in bottom of fire pit on pavers

Crushed stone, such as limestone or granite, offers exceptional heat resistance and durability. It is less likely to compact or shift over time, making it an ideal choice for heavy-duty fire pits.

Paver Considerations

The type and thickness of pavers play a crucial role in the stability and heat resistance of a fire pit. Pavers that are too thin or made of a material that is not heat-resistant can crack or break under the intense heat of a fire.

Additionally, pavers that are not properly spaced or leveled can shift or crack, creating an uneven surface that can be dangerous.

For fire pits, concrete, brick, or natural stone pavers are recommended. These materials are all durable and heat-resistant, making them ideal for use in fire pits. When choosing pavers, it is important to consider the thickness of the pavers. Pavers that are at least 2 inches thick are recommended for fire pits, as they will be able to withstand the heat and weight of the fire without cracking or breaking.

Proper Spacing and Leveling

In addition to choosing the right type and thickness of pavers, it is also important to properly space and level the pavers. Pavers that are not properly spaced can crack or shift, creating an uneven surface. To ensure that the pavers are properly spaced, use a spacer between each paver.

A spacer is a small piece of plastic or rubber that is placed between the pavers to create a consistent gap. Pavers that are not properly leveled can also crack or shift, creating an uneven surface. To ensure that the pavers are properly leveled, use a level to check the surface of the pavers.

If the pavers are not level, use a rubber mallet to tap the pavers into place until they are level.

Insulation Layer

What to put in bottom of fire pit on pavers

An insulation layer is essential beneath the fire pit to safeguard the pavers from heat damage. High temperatures generated by the fire can weaken and crack the pavers, compromising their integrity and stability.

  • Protection from Heat Damage:An insulation layer acts as a barrier between the fire and the pavers, absorbing and dissipating heat effectively. This prevents excessive heat from reaching the pavers, minimizing the risk of damage.
  • Improved Longevity:Protected from heat damage, the pavers will maintain their structural integrity and aesthetic appeal for a longer duration. This reduces the need for frequent repairs or replacements, saving time and resources.

Suitable Insulation Materials

Various materials can be used as insulation layers, each offering specific advantages.

  • Firebricks:High-temperature resistant bricks designed specifically for use in fire pits. They provide excellent insulation and can withstand extreme heat.
  • Ceramic Blankets:Made from ceramic fibers, these blankets are lightweight, flexible, and highly effective in insulating fire pits. They conform easily to irregular shapes and provide excellent thermal protection.
  • Expanded Metal Lath:A thin, expanded metal mesh that can be used as an insulation layer. It provides good heat dissipation and allows for proper drainage.

Thickness and Placement

The thickness of the insulation layer depends on the size and intensity of the fire pit. Generally, a thickness of 1-2 inches is sufficient for most applications. The insulation layer should be placed directly beneath the fire pit, covering the entire area where the fire will be contained.

Fire Pit Design

The design of your fire pit is crucial for ensuring its functionality, safety, and aesthetics. Here are some key factors to consider:

Size and Shape

The size and shape of your fire pit should be determined by the available space and intended use. A smaller fire pit is suitable for intimate gatherings, while a larger one is better for larger groups or cooking purposes. The shape can be round, square, or rectangular, depending on your preference and the available space.


Proper ventilation is essential to prevent smoke buildup and ensure the fire burns efficiently. Ventilation holes or gaps should be incorporated into the design to allow for airflow. These holes can be located at the bottom of the fire pit or around the sides.

Ensuring the safety of your fire pit is paramount. Follow these crucial precautions to prevent accidents and protect yourself and your loved ones.

Always prioritize safety when using a fire pit. Take the necessary precautions to prevent accidents and protect yourself and others.

Safety Tips

  • Keep a fire extinguisher nearby in case of emergencies.
  • Never leave the fire unattended. Always supervise it until it is completely extinguished.
  • Ensure proper ventilation to prevent smoke inhalation.
  • Maintain a safe distance from flammable materials, such as wood, furniture, and overhanging branches.
  • Keep children and pets away from the fire pit.
  • Never use accelerants like gasoline or lighter fluid to start the fire.
  • Extinguish the fire completely before leaving it unattended or going to bed.
  • Check the weather forecast before lighting a fire to avoid using it during windy conditions.
  • Be aware of local fire regulations and restrictions.
