I'm fitting wooden joists into holes in a brick wall,
and between blocks.
Is it best to cement them in tight,
or might dampness permeate?
or to leave a gap and wedge them in with wood wedges
and slate underneath
so there's ventilation
(or but a gap for water to get in?)

When I've done this I've wrapped the joist end in damp proof
membrane before slotting it in, a couple of wedges to hold it,
and then mortared it. Whoever replace my dinining room
floor, though, just rested the joists dry on the cellar walls,
though wrapped in membrane.

It doesn't rhyme and it doesn't scan.

The modern practice is to use joist hangers Which means you don't need
holes in the wall.
It reduces air leaks, is quicker and less chance of the wood
deteriorating in the future.

Instead the metal hangers can rust through

They are on the inner leaf, quite thick steel, galvanised and embedded
in cement.
So not a problem.
Also joists could be replaced much easier than traditional ones.

In article <167bdd29-9d75-4b84...@googlegroups.com>,
They're galvanised, or even stainless steel nowadays.
If they rust, the timber won't have stood a chance.

They are between an inside wall and an I beam
so I hope dampness wont be a problem.

I couldnt find joist hangers that size,
and want a ceiling on my bedroom by christmas
so i'm putting them in slots.

I'm using line ends as punctuation,
to help convey the sense of my posts.

You’re not printing them so its not wasting paper!

In a few years lots of people will be doing this too!
