Do You Need an Insert for A Fire Pit?

Firepit insert is not just inserted into your fire pit for aesthetic reasons alone (even though it adds a kind of beauty to your fire pit); they are inserted to help protect your fire pit from the high heat and temperature of burning flame that can damage your fire pit and even expose people to danger; hence these inserts serve a very important purpose.

There are, however, certain situations that will make using a fire pit insert optional for you. The questions below will help you figure out if you must have an insert in your fire pit or if you can do without them.

1. Is the Heat Generated in Your Fire Pit Greater than 1400°F

If your fire pit generates a lot of heat, you must use an insert to protect the fire pit from exploding and collapsing from the heat. This is because these inserts are made of very strong steel, which can withstand these amounts of heat without exploding or melting.

2. What Material is Your Fire Pit Made of

There are some materials that, if you build your fire pit with, can withstand the heat of the flame. Materials like landscape pavers, bricks, and poured cinders are great for building a fire pit, and they do not need an insert as they withstand the heat.

If your fire pit is built with a compressed concrete block, you will need an insert because concrete blocks have cracks and pores. These can trap water and gases inside the blocks, and when the heat of the fire pit is increased, it will cause the water and gas that is now boiling to heat up and cause an explosion that can hurt people and destroy your fire pit.

3. Can You Afford to Pay for a Fire Pit Insert

Installing a fire pit insert can be quite pricey, but the good thing is that it will yield years of benefit. Secondly, safety is worth every single cent you pay.

Many people shy away from using a fire pit insert because they do not want or cannot pay the price for acquiring one even though they need it.

4. How do You Want Your Fire Pit to Look

Several people want a rustic look on their fire pit; the rough edges, irregular unit shape, and somewhat cracked sides and top of their fire pit appeal to them.

To these people, an insert might not sit well with their taste. There are, however, many people who love the refined looks of their fire pits, on which everything is built and finished to perfection. The fire pit insert adds a perfect touch to their perfectly built fire pit for this set of people.

5. Can I Get the Size and Shape of an Insert that will Suit my Fire Pit?

Before choosing the dimension and shape of your fire pit, ensure that you have the right size and shape of fire pit insert in stores and online.

If not, you will need to get one customizer, which means you will have to pay a little more for your fire pit insert.

How Do You Build A Square Fire Pit For Concrete?

To build a square fire pit, you need the following materials:

  • Peebles
  • Stakes
  • Type 2 cement 
  • Type “S” mortar
  • Gravels
  • Firepit metal bowl
  • Reba wire mesh
  • Steel wire
  • 2 X 12 boards, 
  • Forming nails
  • 2 X6s.

The steps below will guide you on how to build your square fire pit.

1. Grade the area where you will be building your square fire pit, ensuring that the foundation is properly built. You should also add some Base rocks or sand to ensure that the area is leveled.

2. Build the concrete exterior form by bailing four 4-foot long 2 × 12 fir boards to make a square. Set this square on the graded area. Secondly, you make you build another square with 2 × 6s and still 4 feet long.

You then set one square on top of the other and secure them with 2-1/2 feet long forming stakes set outside the form. To keep it from shifting and secure it firmly to the ground, use 2 stakes for each side. Always ensure that the square is level on the ground.

3. You should build another square following the same procedure as in step 2 above; the only difference is that this square will be 10 inches shorter than the first square as it will form the frame’s interior. The height, however, must be the same as the first square.

You then set this smaller square into the bigger square that is sited on the graded area. Ensure that the interior and exterior frame is balanced and even on all sides.

If you fix it properly, the gap between the two squares will be 5 inches. You then put the stakes on the inside of the frame while ensuring that the frame is level.

4. To reinforce the structure, a 20 inches piece of rest is driven into the corners of the squares and every foot inside the frame. You must ensure that the rear sits below the edges of the frame and that it sits securely. A 4 -foot piece of the rear is run horizontally between the vertical rear while a steel metal wire is used to tie them together.

5. Pieces of wire mesh or matting are cut and fitted into the form you now have to reinforce the structure further. Then tie to the rear grid with wire.

6. You then pour concrete inside the gap or space between the two squares. As you do that, tamper down the concrete to ensure that no air holes are left in the concrete. You then smooth off the top using a trowel. Tap the firm while the concrete is still wet – this releases the concrete from the form while drying. Allow the concrete to dry for 24 hours.

7. After 24 hours, the concrete would have dried and set up. You should then carefully stripe the firm leaving the concrete frame standing by itself. 

8. To add finishing touches to the concrete frame, add a thin layer of mortar along the outside of the frame to add a smooth finish.

9. Fill the square to about 75% full of gravel so that the top of the fire bowl will be flush with the top of the concrete frame.

10. Set the bowl to balance on the top of the gravel, adding or removing gravel as you try to achieve the best height for the bowl.

11. To give the fire pit a beautiful look, add decorative rocks along the outside of the bowl until only the top rim of the bowl is exposed. Mexican Peebles is an example of a large cobble that you will fit into the space.

12. You can add a flagstone or slate to cap the concrete frame. And there you have it; your square fire pit is complete.
