Cinder block fire pit safe.

Materials used in fire pits need to be thoroughly considered. Fire s can be built almost anywhere and the cinder blocks simply serve as a useful perimeter to keep in sparks and absorb heat. When positioned near intense heat they can explode. Don t position fire pits in hazard prone zones with unfavorable winds.

For a square fire pit place the cinder blocks side by side instead. After all rows of cinder blocks are in place add a three to four inch layer of gravel to cover soil and provide drainage. Place a second layer of cinder blocks on top of the first layer spanning the spaces between the blocks in the first row. For circular fire pit you need to gradually set the first layer of cinder blocks around the circle.

This creates greater stability for the fire circle. About every 3 feet turn one of the blocks at a slight angle to make an opening for air to get into the pit. Plan to install your fire pit on a patch of level ground in an open area of the yard that s at least 15 feet from other. Make sure that the hole in the blocks facing upward.

Porous rock non treated river rocks and also even cinder blocks must not be used inside a fire pit. Conventional structure bricks will ultimately crack and require replacing gradually. If your cinder block fire pit is on a grassy surface consider removing four to six inches of soil and setting the first course of cinder blocks below ground.
