Will a Fire Pit Damage your Concrete Patio?

The short answer to the above  question is “yes!”  A fire pit can damage a concrete patio. How much it damages the concrete depends on many factors, including how long it has been since your last resealing or resurfacing!

The general consensus is that fire does not damage the concrete itself, but the heat that it emits can damage your patio foundations. Plus, cracks will begin to form if the concrete is exposed to heat over long periods.

These cracks are dangerous, as they allow water to seep in. You have probably already heard that concrete is porous, but did you know it only takes about 30 minutes for the surface of your patio to absorb enough water to cause damage?

How quickly this happens depends on the type of concrete you have and its thickness. Some types of concrete are more porous than others, which means it’s important to do your research when buying a fire pit for your patio.

How Do I Protect My Concrete Patio from a Fire Pit

There are several ways you can use on how to protect your concrete patio from a fire pit. They include:

1. Using an Above-Ground Fire Pit 

This is the only way to go if you want your concrete patio to stay in pristine condition! Using an above-ground fire pit will protect your foundation from any damage. Plus, it’ll be easier for you to clean up after a party or gathering as well.

Just make sure there are at least six inches of clearance between the bottom of your firepit and the top surface of your concrete – that should keep everything safe and sound. You can also use rocks around the edges instead of sand, which looks more aesthetically pleasing than plain old dirt!

2. Fire Proof Heat Pads and Mats

These products are great for protecting your concrete patio from fire pit heat. How do they work? It’s simple: you lay them down on top of the surface before placing the firepit over it, and then take it up once the party is done!

The mat will keep any high temps in check while also keeping your foundation protected. Plus, these mats provide an anti-slip surface which means you won’t have to worry about anyone getting hurt around a hot bonfire.

3. Build Pavers Between the Concrete and Fire Pit

Again, this is an excellent way to keep your concrete patio safe from any damage.  If you have a wood-burning fire pit, then building pavers is definitely the way to go!

All you’ll need is a few pavers and some sand to put in between them. At the end of the day it’s up to you how much you want to spend on your fire pit and how much work you’re willing to do!

These blocks will work as an insulator and will prevent heat from penetrating the patio foundation. Plus, you can place them around your fire pit for an added touch of beauty!

4. Build your Fire Pit at least Thirty Inches above the Ground

This is a good rule of thumb to go by. Build your fire pit at least thirty inches above the ground if you want to safely protect your concrete patio from damage.

This will ensure that the fire won’t come into contact with it, and that there won’t be any accidents or injuries as well!

If you go this route, then make sure your fire pit is constructed from a heat-resistant material such as steel or cast iron. You don’t want to damage your patio surface under any circumstances!

Just remember – the taller the fire pit, the better off you’ll be.

    Hi, I’m Ricky. I’ve been involved in lawn care and landscaping from when I was 15. To be honest, I didn’t like the idea of pushing mowers, collecting grass clippings, and maintaining flowerbeds at the time. But having seem the passion my parents had for gardening and outdoors and the effort they put in maintaining the health and beauty of our landscape, I couldn’t help but not only admire their hard work but also I became a part of it. As someone who loves to spend time with nature’s best, I find myself learning a lot more about gardening and outdoors on a daily basis. Not to mention I love to share the knowledge I’ve gathered over the years with my readers at We Mow Dallas. To be clear, I don’t have a Master’s degree in gardening or anything like that. Everything I’ve learned about gardening, landscaping, and lawn care spring from passion and engagement with my parents. And with a ton of free information out there, plus the ability to run tests and determine what works best for lawn care and landscaping, every day is an opportunity to learn and implement something new. My goal with We Mow Dallas is to teach you exactly how to maintain your lawn and landscape. And since I walk the talk in reality, you shouldn’t hesitate to join me in this wonderful world of landscaping and lawn care. K Beatrice
