Plugging holes in basement wall

[Psan]

I have replaced part of the main pipe from the basement up to the entry level. The main pipe was inside the wall, which has left a big hole.

The idea is to cover the hole on one side, but I don't want to enclose the new/old pipe on the other side which is still in and partially in the wall.

How should I proceed in the simplest way? I have about 8-10cm depth to work with.

Assuming it's the side we see that you want to close. I would have chipped off the plaster over a larger area than the hole. Embedded a net fastened with screws or clamps, plaster net or coarser if you have it, and gradually filled it in with repair mortar. Finally, plaster the surface to match the current wall.

I guess it's the side we see that you want to close. I would have chipped away the plaster over a larger area than the hole. Inserted a net that is fastened with screws or staples, plaster net or coarser if you have, and gradually filled in with repair mortar. Finally, plaster the surface similar to the current wall.

Yes, that sounds like a sensible solution.

It is the side you see in the picture that I want to close, yes.

I had bricked it up with suitable stone and then polished it..

I see that there are brick blocks at 9cm. That's the idea for the height, but could use it for the depth instead. The question is if it will turn out well.

The direction you use the block doesn't matter in your case..

I did that, bought a 9 cm lecablock and a saw blade for leca that fit the reciprocating saw. Then I sculpted. Mortared it with a bit of mortar. And then plastered it.

saw blade for leca that fit on the reciprocating saw

These blades, although expensive, are grateful for cutting leca blocks. Otherwise, you can sacrifice a cheap handsaw or some old axe in the storage.

I was planning to paint that wall in a week.. you're supposed to wait a bit before painting on plaster, but maybe it doesn't matter on such a small area? Possibly paint another layer in a month?

Plaster with something like Lagavägg from Finja so you can paint as you like..

I think the plan is to buy one as below (or similar) which I will divide into smaller pieces and build up with mortar b (?).

Then finish with "laga vägg" for a "nice" surface.

A lot of new things lately...
