Step from the living room to the terrace?

Crushing stone: You already have a concrete slab, right? So now you just dump crushed stone on it and compact it on the concrete slab? I wouldn’t do that.

Einkorn concrete: is probably the drainage-capable concrete you mean. Einkorn concrete has only one stone size and, I believe, different (no?) sand additives. That’s why the water infiltrates.

Gutter: So if you want to be on the safe side, you do that. With a flush threshold, I would definitely do that. It often happens that these are weak points. You don’t notice it for a long time, and when it gets stormier and the driving rain hits it, water is pressed in. With a gutter, that doesn’t happen because the water then stays in the gutter and not at the sealing.

Regarding the outer slabs, there are also different opinions. It also depends on the adjacent covering. But generally, I think at least a concrete shoulder is made there.

Graveling: You already have a concrete slab? Then you pour gravel on it now and compact it on the concrete slab? I wouldn’t do that.

Single-grain concrete: is probably the drainable concrete you mean. The single-grain concrete has only one stone size and, I believe, different (no?) sand additives. That’s why the water seeps away.

Gutter: So if you want to be on the safe side, do it. With a threshold flush with the ground, I would definitely do that. It happens again and again that these are weak points. You don’t notice it for a long time, and when it gets stormier and the driving rain lashes against it, water presses in. With a gutter, that doesn’t happen because the water then stands in the gutter and not on the seal.

Regarding the outer slabs, there are also different opinions. It also depends on the adjacent surface. But usually, I think they at least put a concrete shoulder there.

The landscaper suggested the gravel thing. But we’re doing the terrace ourselves. Since the concrete slab is too low we need to raise it. But then probably better with such a single-grain concrete. I read about the drainable concrete in the Kann catalog.

So we have a normal balcony door, not a sliding door. So there is a small threshold. But then we’d rather do a gutter.

The terrace borders on lawn.

I’m really glad about your opinions.
