I'm going to build an interior wall on a concrete slab.

Should I use a sill gasket between the concrete and the wall?

How should I attach the wall to the floor, is expansion nail enough?

How deep do I need to drill into the concrete?

The wall is only 110cm long. So maybe 2 fasteners into the concrete will be enough?
 
Is there underfloor heating in the slab? Are there any electrical/water pipes?
I would have built the wall with metal studs/tracks.
I would have glued the track on the floor with PL or similar.
 
There is no underfloor heating and no water pipes there.

I'm considering if there are concrete nails that can be hammered in instead so I don't have to get a rotary hammer :-/

Buy the cheapest you can find. Or buy a good drill bit for your impact drill, but it probably won't work if it's really hard. The cheapest rotary hammer is better than the impact drill. But I think the idea of gluing was the best.
 
But what is the exact glue (PL) needed? It should adhere to both concrete and metal.

I thought maybe it's enough to just have the lower rail made of metal (saw it on TV once).
 
I have underfloor heating in concrete and have glued steel studs with PL400. Not saying it's the best, but it was the best and simplest I could think of.

If you then need to sand the concrete and level it with self-leveling compound, are there any disadvantages with each method? Personally, I don't see any pitfalls.

Today I built the interior wall. It was a hammer drill and nail plug. Turned out well. And instead of sill paper, I used double layers of age-resistant plastic between the concrete and the sill.
 
What kind of rotary hammer was it?
Did you use a metal rail at the bottom and drill holes in them first before using the SDS drill?
 
I bought a Black and Decker KD975KA-QS hammer drill at byggmax and had a wooden stud at the bottom. First, I drilled through the bottom stud with a wood drill. Then I measured out exactly where it should be (with a laser level) and drilled through the holes with a concrete drill (SDS+).

The laser level is a Bosch PCL20 that can project a point up and down. That made it easy to get everything right.
