I'm going to tank our damp but not wet cellar using a membrane. I've
been told that you leave the top on the membrane open at joist level
to allow the wall to breath, so I assume that I will need to add
plenty of ventilation at joist level (just above ground level in
effect) to allow the damp to get away, but is there a better way to
do it than adding a few air bricks round the house? Currently there
are only three points the cellar can breath, and one of those is the
coal chute so is not properly open because it has a cover on it.


cross-flow ventilation is what it needs, and simply adding one or two extra
9 X 6 airbricks per elevation is the simplest, cheapest and most effective
way of achieving this

BTW, I'm not talking about the ventilation for the rooms that the
cellar will have after tanking - I was planning on using a humidistat
controlled fan to vent those to keep any damp down.

I would do the ventilation first. That might turn out to be all
you need to do.
