Question for the concrete guys

I have an outdoor wood boiler sitting on a 6 inch concrete slab that I poured. Its in a 12 x 24 foot building I built. The concrete floor is only on half the building. The other half is dirt and its where I store my firewood.

I'm afraid that an ember from the stove might roll out onto the area where my wood sits and start a fire. So I want to get some concrete block and build a knee wall about 2 courses high. The block would sit on the edge of the current slab.

So....I'm thinking that I will need to get a hammer drill and drill some vertical holes on the edge of the slab and insert rebar (do I need to bond it?) down into the holes so that it will tie the block into the slab. There is a possibility that a log from the wood storage side could roll down and hit that knee wall. So the wall needs to be pretty sturdy. In addition to the rebar, I'm thinking that I'll need to fill the cavities in the block with mortar, too.

Just wondering if this is the right way to do it. If you have any suggestions, please share!

Thanks!

i would drill your dowels into the slab with a 5/8 bit buy a tube of epoxy and squirt some in. you need to fill a least the holes with rebar in it.

Thanks guys. I used the epoxy in the tube and got the dowels in this morning. I didn't finish the job today as I had wood to split but I'm going to set the block in the morning.

I think I would go a few more courses than two. I 'd make it substantial enough to stack wood against. I'd probably fill more block than I need to.

I didn't want to go higher because when I open the door to the OWB and use the shovel or fork (they have long handles) the wall would get in the way.

I ended up filling all of the blocks and tying them all together with rebar. I'm going to install some vertical 2x8s and use wire mesh so that I can stack the wood against those. The openings will allow room for me to use the tools, too.
