Is pea gravel fire resistant?

This blog post will answer the question, “Is pea gravel fire-resistant” and cover topics like the fire-resistant properties of pea gravel and frequently asked questions related to the topic.

Is pea gravel fire resistant?

No, pea gravel is not fire-resistant. Pea gravel may erupt in a fire pit. Because pea gravel is porous, it may store water. When the water warms up and turns to steam, the pressure exerted may cause the little pebbles to explode.

What is pea gravel, exactly?

Crushed stone and pea gravel are sometimes mistaken, although they are not the same. Crushed stone is bigger than pea gravel, has a rougher texture, and is generally only available in white or grey hues.

Pea gravel, also known as pea shingle, is made up of tiny stones with rounded edges that have weathered to become smooth. The stones are tiny, measuring around 6-10mm in diameter, and come in a variety of colors, including neutrals like grey and brown as well as more colorful hues like pink and blue.

It is preferred over crushed stone for landscaping projects because of its pleasing appearance.

Is it possible to use pea gravel around a fire pit?

Yes. Pea gravel may be used around a fire pit to enhance the overall appearance of the environment. You may also use river rocks, gravel, brick, or stone pavers instead of pea gravel.

Choosing the right style for your fire pit is important since it helps you relax more while you’re enjoying a backyard escape.

What Gravel Can Be Used In A Fire Pit?

You can use lava rock in a fire pit. Choosing what to put in the bottom of your fire pit requires more thought than you would imagine. If your fire grows too hot, hard rock, gravel, and sand, for example, were not built to endure high temperatures and may ignite and explode.

Fill your fire pit with lava rocks or lava glass beads instead. They’re a safe way to add to the beauty of your fire pit while also providing drainage.

While some people prefer a concrete or stone foundation over a fire pit filler, the latter gives your fire pit a wonderful aesthetic that might enhance your backyard landscape.

What can you do with pea gravel?

Pea gravel may be used for a variety of purposes, and one advantage that may appeal to some homeowners is its low cost. It’s also simple to set up and maintain; just rake the stones into position and pea gravel will appear brand new.

  • Landscaping:  Pea gravel can be a great addition to many landscaping projects, such as around flower beds, because of its vibrant colors and smooth texture.
  • Driveways:  Pea gravel is a fantastic option for driveways because it is resilient, has good drainage, and is simple to maintain.
  • Walkways: Pea gravel may be an appealing and safe pathway material with its smooth surfaces and rounded edges, while also giving a pleasing crunch underfoot.
  • The base for paving stones:  Pea gravel may serve as a stable base underneath paving stones because of its tiny size and inherent strength.
  • Mulching material around plants: Pea gravel is an excellent mulching material since it suppresses weed development and maintains moisture.
  • House borders: Pea gravel is a good draining material that also functions as a barrier against rats since they can’t dig through it.

How Can Lava Rocks Be Prevented From Popping?

Your lava rocks are bursting in your fire pit because they have water within them. Lava rocks are porous, similar to sponges. If the rocks are moist, water might get trapped within. When the lava rock is heated, the water turns to steam.

When it converts to steam, it expands. The expansion of the water might shatter the lava rock, causing it to erupt. In a fire, wet boulders may explode. To avoid lava rocks bursting in your fire pit, follow these easy instructions:

  • Purchase and cure new lava rocks
  • Cover Your Fire Pit When Not In Use
  • Dry the Lava Rocks If They Get Wet

I will now elaborate on the guidance given above.

Purchase and cure new lava rocks:

Curing lava rocks before using them in a new propane or gas fire pit is a good idea. Even if they say they’re pre-cured, it’s a good idea to stick to this method. If you get fresh lava rocks for your fire pit or need to replace old ones, repeat the process.

Cover Your Fire Pit When Not In Use:

To prevent lava rocks from bursting in your fire pit, keep them dry. If you’re going to leave your fire pit outdoors, cover it to keep the lava rocks from becoming wet. Cover your fire pit when not in use to keep the lava rocks dry.

Dry the Lava Rocks If They Get Wet:

If your lava rocks become wet or rained on, you’ll want to dry them out. If the lava rocks get very damp, the curing procedure must be repeated. If they only got a little moist, though, you don’t need to cure them again.

At what temperature do Rocks explode?

Internal gaseous buildup and expansion following heating are two possible causes of rock explosions. However, the crystalline structure of the rock resists both, and when that limit is reached, they tend to fly apart.

The temperature of the explosion might be anywhere between 90 and 200 degrees Celsius (300–400 degrees Fahrenheit). However, if there is water nearby, rocks may explode due to freezing. When water is pushed to freeze, it creates immense pressures, which might cause an explosion if the rock can withstand them.

What Can I Put Around My Fire Pit On The Ground?

Keep your fire pit at least 10 feet away from any trees, overhanging branches, fences, shrubs, or flammable structures on your property. Clear any dry brush from the area around the fire pit before building it, and make sure it meets local regulations.

Fire Pit Rocks You Shouldn’t Use

Pea gravel has previously been explained, but you may be asking why it is porous. The majority of pea gravel is made up of crushed tiny or big river boulders. Sandstone, limestone, and basalt are common among these rocks.

When choosing fire pit stone, a good rule of thumb is to avoid river rocks. These smooth stones, whether large or little, have a propensity to retain water, which heats up and expands faster than the rock can manage, resulting in a fracture or explosion. Other stones to avoid include:

  • Sandstone
  • Cement Blocks
  • Limestone
  • Pumice

How does pea gravel stack up against the alternatives?

Pea gravel is often mistaken with other, similar materials such as crushed stone or crushed granite, as previously stated. Pea gravel is inherently smoother than both of these options, making it more comfortable to walk on. It’s usually more colorful, and it’s usually less expensive.

Crushed stone and crushed granite are both utilized in comparable applications and have their own set of advantages. Larger stones like this perform better with loose-fill applications, and granite is very robust, making it an excellent option for driveways. 

For others, the coarser, jagged appearance of these materials may appeal more than the rounded appearance of pea gravel. We believe pea gravel is a great material for a variety of purposes, but picking the ideal material for your landscaping requirements comes down to personal preference.

Pros and Cons of Pea Gravel

Let’s get to the meat of the matter. Every construction and landscaping material has advantages and disadvantages. Here are the advantages and disadvantages of this amazing gravel!

Pros of Pea Gravel

  • Cost-effective – pea gravel is one of the most cost-effective forms of gravel or landscaping pebbles. It costs about $5 per bag or $10 per cubic foot, as previously noted.
  • Versatile – this gravel may be used for practically any landscaping project, however, patios and driveways are the most common.
  • Basic to install – although there are a few procedures to follow, a simple pea gravel project does not need any special equipment.
  • Low maintenance — this sort of gravel is simple to maintain. It requires no maintenance after being set and left for years. The same cannot be stated for all rock kinds.
  • Pleasant – walking on gravel is generally comfortable due to the smooth surface. Or at the very least, as pleasant as gravel can be. It’s ideal for playgrounds because of this.
  • Natural weed barrier – you may wish to add a weed barrier for more protection, but this gravel works well as a weed barrier on its own, so you may skip it if you choose.
  • Easy to find — if you’re searching for pea gravel, you’ll find it at any hardware or garden shop. While other gravel kinds are uncommon, this gravel may be found practically wherever.

Cons of Pea Gravel

  • Usually requires a border – this gravel requires an edger to keep it from dropping. It will sink into the sides or run out and make a mess if you simply set it down on its own.
  • Requires a suitable foundation — pea gravel requires a solid base. When calculating expenditures, you must also include the costs of the additional rocks or filler that you purchase.
  • Sinking furniture — you can’t expect a chair to remain put on the gravel. It’ll start to sink into the gravel. This isn’t safe, and it may make your space seem unkempt.
  • Doesn’t endure indefinitely — this sort of gravel should be renewed every five years or so. It deteriorates until it is little more than a shell of what it once was. However, because of the cost, this is typically not an issue.

Frequently Asked Questions(FAQs), “Is pea gravel fire resistant?”

Is pea gravel OK for use around a fire pit?

Water causes more trapped oxygen to be produced, which enhances the chances of a rock explosion. Using pea gravel anywhere near your fire pit area is not a good idea. Pea gravel should not be used around the fire pit since it may get too hot and burst.

What caused my fire pit to erupt?

Water may be trapped within concrete blocks, pea gravel, river pebbles, and other materials often used in DIY fire pits. When heated, they have the potential to explode.

Do rocks catch fire and explode?

Rapid expansion owing to retained water within the rock or uneven heating may cause rocks to explode in a campfire. Although almost all rocks include some water, porous and more permeable rocks contain more water and are therefore more deadly within a fire.

Is it possible to burn charcoal in a fire pit?

Yes, charcoal may be used in a fire pit. Charcoal is wood that has been burnt in an oxygen-depleted environment, yet it can still burn more efficiently and generate heat, making it a wonderful alternative for cooking in your fire pit.

For a fire pit, what kind of sand should you use?

For a fire pit, beach sand is an excellent choice. It may be used as a substitute for gravel or river rock, and it is inexpensive since you are likely to have some on hand from the beach! It’s simple to locate and, depending on where you live near the ocean, maybe free.

Is red lava rock suitable for use in a fire pit?

Lava rocks are ideal for fire pits because they scatter flames, distribute heat, and look fantastic when lit. They can resist very high temperatures without splitting or exploding (when burned from the inside out), and they can also maintain heat for many hours, making them perfect for all sorts of fire pits.
