Garage drain for condensation water, how to do it correctly?

Hello,

does anyone here know the best way to install a drain for condensate water etc. in the floor slab? I have been thinking about those grate drains like on terraces in front of windows. Apparently, they are available as meter goods. Would you simply embed them in the concrete of the floor slab, possibly leaving them slightly higher to later achieve a slope with a kind of screed? Creating a slope already in the floor slab (6.5m x 8.50m) is probably difficult, right? From where to where is the slope usually made? From front and back to the middle, or from left and right to the middle, or four triangles to the middle?

Thanks

Hello,

where is the water supposed to flow when it has run into the gutter? There would have to be a drain. I can't think of any garage off the top of my head that included a drain. If a lot of water has actually accumulated: use a rubber broom and transport the water to the drain in the yard.

Best regards

Michael

where should the water flow

well, under the base slab there is a drain leading outside, something like in the toilet in the house.
You can find a lot on Google about garages without a drain and with incorrect slope which then cause the owners a lot of trouble.
I thought I would avoid it; if it is done correctly beforehand, the additional financial cost should be "low."

We have not planned a screed for our garage. Instead of this, we will lay paving stones (in a more elegant look) so that water can seep through into the underlying soil. We also plan a slope towards the gate. So if there is a lot of water in the garage that can no longer seep away, it will flow towards the exit into a channel covered with a grate.

From there, the pipe joins the drainage pipes from the roof towards the infiltration shaft. We are only doing this because we have decided for ourselves not to perform oil changes or other work involving disposable liquids.

A friend of ours is a car mechanic who often performs oil changes etc. for friends in his garage. He has a drain with an external wastewater tank.

Hm paving actually seems like a good idea too, right? I have to discuss it with the planner, but I already suspect that I will ruin the calculated statics with it. It should only allow water/snow to drain, no oil or anything else.
