I need advice from somebody with materials experience re: cement/mortar and fire pits
Here's the thing, i am working on an outdoor fire pit, and rather than sand or gravel in the bottom i want to use a cement or mortar to create a solid ember-proof surface. The ground is very rooty, and due to septic we can't thoroughly dig it out. I don't want to cause a fire to spread through our sandy ground.
I am trying to find a mortar or cement, or trying to learn how to custom mix such a mortar or cement that won't crack or blow up when heated by firewood. That's all i need in order to make my firepit.
Somebody previously gave me a lead on Sakrete's "grey style high heat mortar" which would have been 100% perfect for my purpose except i cannot buy it ANYWHERE. I am unable to ship to my house or pickup from Lowes because the system won't let me. Home depot doesn't carry it. Ace doesn't have it. I looked in online only sources and still nothing.
Im just trying to do this project right… it'll be outdoors, exposed to the rain, obviously with fire in it, and i know Jack squat about which cement-type materials are safe for, and will hold up to, the job, like at all.
I need y'all's help. Please.
