A lot of the houses on our road suffer with damp in rooms at the front

On moving in, we noticed active damp in a master room at the front of the house. The opinions we got at the time where either very expensive damp proof materials (chemical injections etc), or we were offered the suggestion of using tanking slurry to waterproof the wall. This has effectively worked, that room is now dry.

We are now doing a Reno and having read much more about breathability we’ve started to worry about this. We are wondering if we get the render done in breathable lime render, could we keep the wall as it is (remove the tanking will also be damaging for it we understand)

We’d welcome views on how much of an issue it would be to have one room be tanked/not breathable - if we then get the render done breathably.

Whilst we are reluctant to invasively remove the tanking we don’t want to be storing up too many problems]]>
