Yes, it is possible and this may be the fault of a wall tie. When cavity walls are built they are fitted internally with wall ties to keep the walls level and stable. These wall ties often have a ring of rubber or a twist in the centre which stops the external damp travelling through to the internal leaf of wall. If these ties become rusted or defunct then obviously they cannot carry out their function anymore
Browse through the project list and take a look at the project for Replacing Wall Ties.
I hope this is of use to you
All the best.
