crumbling mortar and water coming through the brick work!

[dcoonster]

Ok i remember a while back somebody told me about a particular type of mortar that had to keep a certain amount of moisture...is there such a thing and is it a lime mortar mix???

Ok thats the first question, next! Basically i've notice only in the past week or so a damp patch keeps appearing on the floor boards near the outside wall. I think it's a lime mortar mix because it's quite crumbly, but what i've noticed is dust has settled between the floor boards and walls. Is this possibly causing the water (where ever it's coming from) to transfer from wall to floor? (which after reading sounds quite obvious!)

There is also a few bricks missing from the inside wall and i noticed when i put my hand inside there was no cavity, is this normal???

Getting a builder to come round this evening to have a look and another tomorrow night, just need a bit of advice so i know what to expect i.e. what kind of issues he should be bringing up!

Lime Mortar lets the walls beneath 'breathe'.
It is usually used on Cob walls, which are usually found on pre 1900 houses, although this can differ
