Remove embedded wooden studs in concrete wall

[magnus74]

Hi,

I live in a house from the 70s where the basement construction is such that the insulation (I think it's styrofoam) is on the inside, between wooden studs "cast" into the concrete wall and thus recessed.

Drainage and insulation from the outside have now been done, and the studs and insulation should therefore be removed! But I imagine that this can be quite a tough job since it might be firmly attached. Does anyone have experience with this and can provide tips on good tools and work techniques?

Grateful for any tips!

Assuming you have an EW foundation with load-bearing standing wooden studs cast into the bottom slab and nailed to the concrete wall. We, like you, have redone the drainage and insulated the outside. The insulation on the inside was removed except for the upper part. The construction company sawed off the bottom 20 cm of the wooden studs and replaced them with some type of metal plate that was cast into the bottom slab. They sawed with a reciprocating saw and then knocked it loose with a sledgehammer (it was held firmly as they were nailed). Then they had to chip away the embedded wood. It didn't seem easy... Then they installed ventilation pipes in the walls and the new raised floors (Nivell). Everything turned out very well, no lingering smell or moisture after 1 year. But it was expensive, over 400 thousand.

Well...not sure if this is the same. For example, I don't think the studs are attached to the bottom plate, but I'm not sure. I'll get back to you on this.

If it is an EW-grund, I assume the studs can't just be removed, since they seem to have a load-bearing effect as well as holding the insulation in place?
