I'm starting to plan my build of a backyard grill station / pizza oven. I plan to build a concrete block wall about 4 feet high. I'll put either concrete or stone surface on top, as well as a 1600 lb brick pizza oven, so it will be supporting a fair amount of weight.
I'm a complete novice to masonry projects, so I'm learning as I go. I have two questions:
1) Part of the wall will be built on what is currently dirt in a planter area; the rest of the wall will extend onto existing pavers. Do I need to pour concrete in the planter as a foundation, level with the pavers? Or can I get away with compacting crushed gravel as a base in the planter?
2) The grade of the pavers angle slightly down, toward a drain. What's the best way to level out the base of the wall that will extend onto those pavers?
Hopefully I provided enough info to get a few suggestions.
Thanks! David
