Ground-level terrace, any experiences in planning the slope?

Build a wooden terrace. Then you can confidently do without a channel and a slope.

Build a wooden terrace. Then you can do without a gutter and slope with a clear conscience.

2 pallets of porcelain stoneware are already bought :-(

Now the matter becomes a bit clearer. I hadn’t expected an angled floor plan. And when I read "Komfortschwelle," I can certainly understand the oversized channel. Basically, a slope from top right on the plan to bottom left on the plan would make sense here to channel water away from the house. The larger part of the terrace is at the top of the plan by the house; from there, I would definitely create a slope downward. Whether it needs to be 2% or if 1% is enough is up to you. The main thing is that water does not run against the facade during normal rain. From right on the plan to the left, you could technically set it without a slope, but then you would be entirely reliant on the channel during heavy rain and on it not being blocked by leaves that have been rotting there since the autumn before last. That’s why I would also use at least a 1% slope here.

I thought the same, which is why I also drew in the slope from top of the plan to bottom of the plan. The 2% slope from left on the plan to right on the plan refers ONLY to the grate. This MUST be done by the precast company (guarantee) with a slope from right on the plan to left on the plan. Therefore, my original question again: should I lay the grate with the same slope as the slabs from top of the plan to bottom of the plan? Or does that look strange? Is that even done??? To set a grate slanted lengthwise? Oh yes, there is no channel under the grate, but rather a "soakaway frame around the house." By that I mean that around the house, 30 cm away from the base, there is only gravel (16/32) in which the water infiltrates.

oh yes, one more big question arises! under the strip foundation there is a strip footing, something will be mounted on it. I also need a curb stone at least 8cm thick to securely attach the grid grate with angle brackets. (I have 20cm shuttering stones).



now I wanted to ask how I best lay the porcelain tiles on the shuttering stone???

Option 1: I make the shuttering stone 4cm deeper and apply 4cm drainage mortar.

Option 2: (a tile setter friend told me): I set the shuttering stones 6-7mm below the tile underside and apply 6-7mm tile adhesive and bond the tiles with the shuttering stones.

Option 3: I lay the tiles in gravel. Since I am laying the remaining tiles behind the shuttering stone wall anyway in a gravel bed, that would be my preferred option. BUT since the shuttering stone top edge protrudes empty on the right side, all the gravel would run out.

Your sketch does answer the question. If you set the grate with a slope and the terrace not (or vice versa), then you get a strange kink. That’s why I would set both as much as possible on the same level. How big are your slabs and how thick? Thin and large slabs are either laid with mortar or on pedestals. On gravel, they will eventually start to wobble.

thanks 45x90 Around the house we also set one row of slabs. We would like to lay these in gravel in case one needs to be replaced.
