A solid concrete block wall that is very wet and showing signs of white salts..

[johniosaif]

Seeking solution to a probable problem in the future, one wall seems to have been soaked and has white spots ie salts in the block work, I assume render will only seal the salts for a while..I do want it to dry beforehand obviously but it will be slow to dry.. Solutions etc please . to update and clarify ,it is external rendering that is due to go on it..

If your rendering it salt inhibitor

Membrain and dab. As nothing can get through the membrain. Or just batten and board mate.

Carlos is right imo on this ,why so much salt is it below ground level ?

No its about eight foot off ground level, any concrete material can have salt deposits especially when wet over a long period..

You could tank it with a sulphate resistant waterproofer.
