I'm getting closer to finally building my RMH. My mass will be "framed in" using bricks, I'll fill the void of the mass with 8 inch pipes and pea gravel. Cob is not an option for this build. For the top of the mass I'm looking and making a 2 inch thick concrete countertop type thingy.
Here's a youtube detailing the process of making a concrete countertop
I'm posting here to see if anyone out there has done this. And is there any reason why I would not want to do this?
Any and all feedback is appreciated.
