Is it necessary to line a fire pit with fire brick?
by

I built a fire pit with cement block but the mortar joints have cracked after only a few small fires. Should I start over and use a fire brick liner?

Cement blocks will crack if used in a fire pit. You need to line your pit with fire bricks.
You can use cinder blocks for a fire pit but they have to be fire-rated. This information should be available on the in-store product description or manufacturer’s website. Good luck!
