sloped patio

[TheSteff]

greetings.

i am putting my build onto my newly poured concrete patio. when i had the patio put in, i had one section made extra thick (~ 8" give or take) with extra rebar.

the problem is, the entire patio has a 1/4" slope to it.. like patios are supposed to.

so, if i put the stand right onto it, it will be sloped.

the question is, where is the best place to level it? do i level the first course of cinderblocks and just have over an inch of mortar on the backside? or do i adjust the concrete 'lid', making it level by attaching the forms for it in such a way that the concrete surface is level.

front to back there is about a 1/2" change in height.

suggestions?

I would be tempted to just stack your bricks on the slope and make up the difference when you pour the hearth slab - that is what I did. You could always dry stack the base and see if the slope is enough to bother you before you get too far along.
Which way does the patio slope - towards the oven or away from it? Mine slopes towards the oven and in hindsight I might have poured a slightly elevated slab portion, as when it rains (most days in the winter here) the area where I stand and cook is usually wet even though I have a roof. I put some pallets in the storage area to keep my wood dry but wish I wasn't standing in water when the weather is bad.

Take up a bit of the “slope” in each course of block that way it won’t be as visible to the naked eye. If you plan to cover the bare block/mortar joints with a scratch coat or stone eventually, it won’t matter how you achieve level as long as you get there by the top course.

I'm with JR on this...just dry stack & level your top slab pour. Also important as JR noted to put your oven on the high side of the slope...working pizza while standing on palettes is not for the faint of heart! Amazing how a "forgotten" 3-4" step can upset the apple cart.

i think i found a solution on a masons forum. use a level to draw a straight line all the way around from the lowest point. cut each brick and then turn them over to mortar. first course is then level and i can make up any height difference when i put the top. As you can see from the picture, the difference is significant.

That's the right way to do it . You did good. Dry stacking them only creates more of an issue later, as the ends would be nowhere near plumb when you were done. Good call.
