So we’re DIYing a fire pit area. Prep work is done and we laid out weed control barrier.

We’re going to staple it down and around the pit part put extra staples.

I assume I should cut out the area that will be “below the pit” part? Or just leave it and if it burns away, it jus burns away no problem?

We’re are doing about 2” of rock across the entire area and the pit will sit on top of that with about another 2” of rock inside it. Wood would sit on top of that, so about 4” of rock above the weed barrier.

We’re doing a smokeless so burn temps will be pretty high.

I’ve found those weed barriers you put on the ground are pretty worthless. Better to just sterilize the area before you put the rocks down

Ya I kinda thought about it more and the thing is gonna deteriorate in a year or so anyway. Just gonna cut out the middle under the pit and be done with it.

We did round up and prep, so it should be good to go.

Rocks That Explode Around Firepits

What Rocks Should Be Avoided?

Porous rocks tend to hold a lot of moisture even when they feel bone dry, which means they should be avoided for use in fires. This list includes limestone, sandstone, slate, pumice, shale, river rocks, pea gravel, basalt, soapstone, conglomerate rocks, and metamorphic rocks. Many of these rocks, including limestone, sandstone, soapstone, conglomerate rocks, and metamorphic rocks, are also made from multiple minerals that may heat at different rates and may also contain defects on the inside, both of which can contribute to explosions.
