Do I need to protect concrete from fire pit?
If you’re contemplating building a fire pit in your backyard, you’re probably thinking about the visual appeal and warmth it will bring to your outdoor living space. However, it’s also essential to consider the safety aspect of installing a fire pit. Depending on the type of concrete you use and the location of your fire pit, heat damage can cause cracks in your concrete and may even lead to tipping over, which poses a serious threat to anyone nearby. In this article, we’ll discuss the risks associated with fire pit heat damage to concrete and how to protect your property from potential harm.The Risk of Fire Pit Heat Damage to Concrete
Fire pits are an excellent addition to any outdoor space, but they can also be hazardous if proper precautions aren’t taken. As you may know, most fire pits are constructed from concrete, a sturdy material that can withstand heat and resist wear and tear. However, when exposed to extreme heat for extended periods, the concrete can crack or warp, compromising its structural integrity. In the worst-case scenario, this could lead to a fire pit tipping over, causing serious injury or even fatalities.Types of Concrete That May Be at Risk
While concrete is generally a durable and reliable material, different types of concrete may behave differently when exposed to heat. For example, lightweight concrete is more susceptible to heat damage than standard concrete. And even standard concrete may crack or degrade over time if regularly exposed to high temperatures. If you’re not sure what type of concrete you’re working with or whether your concrete is heat-resistant, consult a professional to verify that your material is suitable for building a fire pit.How Fire Pit Heat Can Cause Cracks in Bricks
In addition to damaging concrete, fire pit heat can cause cracks in the bricks you use to build your fire pit’s outer ring. Bricks are a popular choice for fire pit construction, as they can withstand heat without warping or melting. However, when the heat is too intense, it can cause the bricks to expand and contract, leading to cracks and gaps in your fire pit’s structure. If this happens, it’s vital to address the issue as soon as possible, as a damaged fire pit is inherently unsafe. Pro tip: You can use mortar or fire-rated adhesive to secure the bricks, which will help them withstand heat.The Dangers of a Tipped-Over Fire Pit
If a fire pit tilts or tips over, it can cause extensive damage to your property and pose a severe risk to people nearby. Fire pits that are not properly installed or built on uneven ground may be unstable and could tilt or tip over when exposed to heat or pressure. This could cause the fire, fuel, and embers to spill out, possibly igniting nearby materials and causing an uncontrolled fire. Pro tip: Ensure your fire pit is level and stable before use and regularly inspect it for signs of wear or damage.The Benefits of Fire Retardant Mats
To mitigate the risks of fire pit heat damage and tipping over, consider installing a fire retardant mat underneath your fire pit. A fire retardant mat is a barrier designed to protect floors and other surfaces from heat, sparks, and embers. It’s an excellent way to protect your concrete and other materials from sustained heat exposure and prevent cracks and other forms of damage. Pro tip: Fire retardant mats are available in various sizes and materials, so choose one that’s appropriate for your fire pit’s size and location.How to Properly Install a Fire Retardant Mat
When installing a fire retardant mat under your fire pit, here are some essential steps to follow:- Choose a smooth, level surface on which to place your mat. Avoid placing the mat on rough, uneven ground.
- Clean the surface where you plan to install your mat. Make sure it’s free of debris, dirt, and moisture.
- Place the fire retardant mat on the clean, level surface. Ensure that the mat is large enough to accommodate the fire pit’s dimensions.
- Set the fire pit on the mat, making sure it’s level and secure. The mat should be at least two feet larger than the fire pit’s diameter and extend past the fire pit on all sides.
- Test the mat’s effectiveness before use. Start a small fire in the fire pit and monitor the mat’s temperature to ensure that it’s not melting or degrading under the heat.
