What To Put Under A Fire Pit On Grass

While we love our lawns to be green and well-tended, several conditions and events will hinder our ambitions. A portable fire pit on the grass in your back yard is a quick and easy way to spoil the grass through heat stress. Unless you have a purpose-built firepit outdoor, specially set up in its area, your fire’s ideal placement may be on the grass. It is crucial to create a no-burn zone beneath and around your fire pit.

If you are in the market for a new fire pit or are just considering purchasing one, consider the many new types of fire pits available that are raised and adaptable to smaller backyards. It is worth shopping to find one that is perfect for your grass area to enjoy your fire outdoors. Choosing a sturdy stand is very important. Steel coated stands with a powder coating treatment can provide heat resistance up to 50 degrees.

What to put under a fire pit on grass is a worthy consideration. The floor surface under your firepit can be damaged by the intense heat generated by your fire pit if it is placed directly over the grass. To prevent the grass under your fire pit from getting burnt, you need to take measures to protect surfaces by insulating them from direct heat contact using a protective heat resistant barrier.

Safety Tips

Before you set up your firepit and the firepit accessories, find out if your community allows open fires, and if so, what the rules are about the minimum distance from structures and other objects? If you have a choice between a wood fire and a gas fire, keep in mind that wood puts out more heat. Talk to your insurance agent about whether you must declare your fire pit on your homeowner’s policy. 

Because fire safety is the most important aspect, make sure you have a hose or fire extinguisher nearby. A multi-purpose fire extinguisher is best. It can deal with timber, paper, plastic, trash gasoline, oil, and electrical equipment fires. Make sure you keep your burning fire to a manageable size where you don’t lose control. Rake out any debris and dead grass that might light if an ember manages to escape, and in that way, you reduce potential fuel for any fire.

There are many reasons for putting something under a fire pit, which is being used on grass, with one of the main reasons being the safety of those who are going to be near the fire pit and the burning fire. 

Place some sand in the bottom of the fire pit. Sand will act as an insulator and help to disperse the heat more evenly. Another option is to place some lava rocks in the bottom of your fire pit. These rocks, made out of obsidian, created by lava, are very conducive to heat. Keep the grass under the fire pit wet. Place a spark screen on top of the fire pit once the flames are established. This allows you to see and enjoy the fire while capturing the sparks, keeping them from floating into the air, and possibly landing on the grass and burning it.

Try not to use lighter fluid or other fuels that create scorching flames. It is better if the wood catches fire naturally and slowly, building hot coals at its base. There are several other fire starter products available. You could opt for an electrical fire starter that can efficiently light up your charcoal in seconds. This fire starter provides a flameless and eco-friendly option and gives you better control of the fire in your fire bowl.

Above all, don’t be tempted to use unsuitable materials under your portable fire pits such as wood or a picnic blanket, which could be the very fuel for the fire on your grass, which you are trying to protect.

General Tips For Protecting Your Artificial Grass

Environmental concerns, drought, the improved look and feel of synthetic grass, pet friendliness, and the lack of maintenance required have combined to produce a take-up of artificial grass in backyards. You can still use your firepit on the artificial grass area, but you need to take some precautions. Most synthetic grass is made from high-quality, non-toxic, non-flammable synthetic fibers. This grass won’t catch fire or burn. In the situation of an open fire or extreme heat, artificial blades will melt. By melting, the grass creates a barrier that prevents the fire from spreading.

While it is nice to know that your faux grass is not flammable, be aware that a spark or ember or a piece of hot food could melt the grass in that area. Don’t put your fire pit directly on the fake grass. Perhaps create an island patio area next to or within the grass area. You could use natural stone or brick pavers or another non-flammable material that blends in with the existing landscape. Make your island large enough to hold the fire pit and some comfortable seating around it. 

Be sure to consult with artificial grass safety experts before you plan any activity that could expose your grass to open flames.

Heat Resistant Surfaces

Brick Pavers

One way of protecting your grass from the heat of the firepit is by raising the pit onto a platform of bricks pavers. These will create some extra distance, and they will act as a heat shield. The platform provides a very flat and stable area to place the fire pit on. The brick pavers should create an area slightly larger than the fire pit. If you place pavers in a grid formation under the firepit, they can provide an inexpensive, but robust, temporary barrier between your fire pit bowl and your grass. Place the portable fire pit in the middle of the patio block platform.

Remember to remove the fire pit and the brick pavers afterward so they don’t suffocate the grass. If you or your guests smoke, make sure an ash-tray is on hand to put out cigarettes and dispose of cigarette butts safely.

Fire Pit Pads

To ensure safety and protection as you burn your fire pit on the grass or your wood deck, consider using a protective fire mat or a deck protector. Protective fire mats are specifically designed for fire pits for ground use or as a deck protector. The fire pit mat will catch any hot drippings that may spill or splatter when cooking. They are made with heat resistant materials such as carbon fiber or volcanic rock fiber. Some are made of a combination of materials. Technology has increased the efficiency of design and protection offered. Some fire pit pads are made from the same material used in military aircraft to protect them from heat and fire.  

The fire pit pad may also come with a reflective surface that provides extra protection. For extra sophistication and durability, you could purchase a hand-crafted all-metal fire pad designed to protect against extreme heat. These extra protective pads are constructed with multiple layers of metals with air space between them, creating a natural insulating effect. The heavy grade aluminum used in these sturdy fire pit mat designs is also rust-resistant.

The material it is made of will determine how much protection for your grass you will get from your mat and what it is made of will also determine the price you will pay. The mat will not burn, melt, or allow heat to penetrate when exposed to direct flame. As an extra precaution to ensure durability and long-term usage, place the fire pit pad at least an inch away from the bottom of the fire pit bowl. These firepit mats are available in many sizes and in different shapes designed to suit your firepit size and budget. Some are rectangular while others are circular. The size of the mat, concerning the size of your fire pit, is essential.

Fire Pit Heat Shields

An alternative to a fire pit mat is a fire pit heat shield. A fire pit heat shield is straightforward to use, especially since you don’t need to assemble anything. Check the maximum heat capacity of the heat shield and make sure that you aim to keep to the recommended heat capacity. A good quality heat shield will be able to reflect over 90% of the radiant heat. This generally means that the heat shield can withstand about 1,100 degrees Fahrenheit of continuous radiant heat and about 500 degrees Fahrenheit of direct contact to heat. The firepit heat shield protects your grass or acts as a deck defender, but it will also help your firepit work more efficiently by radiating the heat upwards and outwards.  

These products are made from a quarter-inch ceramic inner pad that is placed between two heavy-duty foils. It is then combined with a stainless steel mesh around the edges.

Fire heat shields are generally very flexible and will mold into any shape. The stainless steel edges add to this maneuverability and hence its versatility. Fire heat shields are made of high-quality materials. These shields would also be suitable as a protective heat barrier for your deck’s outdoor pit fire.
