Garage built with breezeblocks - no waterproofing!

[jazbo]

Hi

Just bought a house with a seperate garage. From the front and the side facing the garden it is brick.

I have just noticed however, that the back and other side that are not viewable unless you walk around there down a gap a foot wide, are plain breezeblocks. They are not even pointed well.

Inside, the garage the two decent walls are dry, however, unsurprisingly, the two plain breezeblock walls are damp.

What are my options to stop the damp inside please?

Render/ rough-cast the outside but maybe you can't get at it?

A cement slurry type tanking on the inside should be good enough to deal with that type of penetrating damp.
