Brick up doorway

[PixelSE]

Hi!

I need to brick up a doorway, but I'm unsure which type of masonry blocks and mortar I should use.

There are some kind of hollow blocks filled with sawdust as insulation. They measure about 49x25cm. The wall is about 25cm thick. I think it's the type of block I found lying outside. I'm attaching some pictures.

What is this type called? Can I just buy Leca blocks and use that? It's a heated garage.

Anyone have any tips on the procedure?

It looks to be concrete hollow blocks, which are best laid with mortar B or alternatively A mortar. When you are closing the gap, you need to insert reinforcement that you drill into the sides of the existing wall in the first course and in every other subsequent course as you build upwards.

That's probably correct. Is it possible to use lightweight concrete blocks + reinforcement, or do I need to get concrete block?

That's probably correct. Does it work to use lightweight concrete block + reinforcement or do I need to get hold of concrete hollow blocks?

It will probably work, do you have any pictures from the outside?

It probably works fine, do you have any pictures from the outside?

Bad picture but this is how it looks. I was wondering if it's possible to use blocks like these: https://www.bauhaus.se/lecablock-benders-25x19x59cm

Yes, you can use Leca, but it's good if you plaster the exterior...

Thanks, I'll go with that. What type of plaster is suitable?

Thank you, then I'll go with that. What type of plaster is suitable?

You can buy mur och putsbruk B, which can be used for both masonry and plastering.

If you want to do it by the book, the wall should be primed with grundningsbruk A, which is applied before the plaster.

Of course, you can choose Finja or Weber if your local dealer carries them instead since they have similar products.
