Basement sanding - grit of the roughing disc - advantage?

Hello,

I don’t think the basement builder will sell us the panes. He is currently much more interested in selling us the complete "service".

Sure, that adds up to quite a few hours ;)

should we pay attention to anything else regarding the panes?

No, the concrete is probably just supposed to be roughly abraded a bit so that it provides better adhesion. Although I can’t recall that we – on behalf of our construction supervisor – ever requested this procedure from the client ...

Best regards

Thank you again.

Yes, it will probably be several hours.
For the sealing with KMB, they take just under 4K (then they probably sand themselves as well).
For a 100mm insulation, another just under 3K.

Wobei ich mich nicht erinnern könnte, dass wir dieses Vorgehen - seitens unserer BU - vom Bauherren verlangt hätten ...

Since we are paying "only" just under 14K for the basement, we were already aware that we would have to pitch in a bit more ;-)

Hello Michael,

Since we are "only" paying just under 14K for the basement, we already knew that we would have to do a bit of work ourselves ;-)

14K for 4 walls, plus floor slab, plus insulation, plus electrical work, plus screed, plus, plus or what is included in the 14K?

Kind regards

I wish ;-)
So the 14K are a base plate, a prefab basement (approx. 8.50 x 9.50) with 3 rooms + basement stairs, basement ceiling, 3 drainages from the wall, floor drain with backflow prevention and odor trap, 4 double-glazed basement windows and of course delivery / installation.
I believe I haven’t forgotten anything. ;-)

We do the waterproofing against ground moisture and insulation ourselves.
