Brick Pavers or Patio Slabs

Using brick pavers or patio slabs is a simple and cost-effective solution. You can pick up a few at your local hardware store and put them under your fire pit.

After using the fire pit, don’t forget to move them off the grass so that there is no risk of grass damage.

While moving them is not really mandatory, it is a good practice because it minimizes the risk of compression or other undesired effects on the grass.

Other Options

If you don’t want to buy anything extra to put under your fire pit, then you will be glad to know that there are other options available.

However, keep in mind that you risk damage to your grass by not putting anything under your fire pit.

Eventually, the excessive heat will lead to your grass turning an undesirable brown color.

Soak the Ground with Water

Soaking the ground with water is the easiest and the cheapest solution to preventing damage to the grass.

It is a viable solution because as the fire pit starts to heat up, the water evaporates before any damage can be done.

You will need to make sure that the grass is liberally soaked and not too much saturated that it becomes waterlogged.

Otherwise, it may not be able to provide a sound, solid place to put a fire pit.

Move the Fire Pit Around

If you put the fire pit in a single location, it will lead to compression, hence damaging your grass.

So, you should move it around the yard to avoid compression and make sure that it is in a safe location.


Fire pits can be placed directly on top of the grass, but you need to do a little work to make sure that your grass is protected.

Watering the grass before placing the fire pit down is the easiest way to protect it from damage.

Moving the fire pit around on a regular basis is also a good practice. For superior protection, consider putting brick pavers, heat shield, or fire-resistant mat under your fire pit.
