Hello
I had to break open a part of the wall in the garage due to a mouse nest and then saw that the sill was nonexistent, more "soil" than wood.
What is the best way to fix this?
The wall is constructed with mexitegel, asphalt board, insulation, wind paper, wallboard.

Decayed garage wall base with exposed insulation and deteriorating sill plate, showing debris and rot near the concrete floor.

Decayed garage wall bottom with rotten wood and exposure due to mouse nest, showing insulation and building layers like asphalt board and Mexi brick.
 
The sill is embedded in the concrete, so it was only a matter of time.

My advice is to brace the wall, saw off the studs a bit above the floor, and cast a ledge for the new sill to rest on.

Thanks for the response, though I'm not entirely sure what you mean.
Do you mean that I should cast it so that the sill is not against the actual slab, kind of like the sill ends up at the same level as the actual floor?

The sill should never be in concrete, only on top with sill insulation.

Outside the outer wall?
 
yes
 
The best thing is to cast a few cm above the garage floor, then there is no risk of meltwater from a snowy car finding its way into the sill. Then you should probably be careful when sawing, etc. so that you don't crack the mexifasaden..

Outdoor patio with a white bench, blue floral rug, and various items including shoes and decor against a brick wall with a glass window.

I have a large bench in front of the wall today, but found an older picture where you can see how the wall looks.
Baseboard + Mexitegel.

When casting, you fill in the entire part where the old sill was + a few centimeters more, not just place blobs here and there, right?

And of course sill paper between the concrete and the new sill.

Had the EXACT same problem at home on the outbuilding with a wooden sill where the floor was cast afterwards, causing the sill to end up in a pocket. Result = rot.

Prop up, cut, and replace the sill piece by piece. I chose to brick it because it's a bit of a hassle to get the molds right, but then I raised it by two bricks, as the building was "on the ground." Here, if I interpret the images correctly, it's enough to just cast the pocket itself.

Would it work to lay a row of lecablocks to raise the sill 9cm above the floor?
You should be able to plaster the part that is above the floor then, right?

yeah. it'll be a bit of a tedious job though
 
Question regarding the sill insulation, should I place it under or over the new row of lecablock?
