Hi, sounds to me as if it is definately rising damp, this can be cured by removing the plaster back to brickwork upto 1 metre from the floor level then either drilling into the brickwork and injecting a waterproof solution to create a new damp proof course or if this has already been done in the past and failed or the brickwork is not in any condition to take it then you can apply a paint on liquid waterproof membrane and then replaster the walls. hope this has been of some help. kind regards, James Ormerod.

Damp to ground floor walls could be caused by a number of reasons therefore correct diagnosis by a csrt surveyor is essential, to avoid unnecessary chemical treatment & cost. If a damp proof course is present, it could be being bridged by high external ground levels giving the appearane of rising damp. Again if a damp proof course is present, but replastering has not been carried out, hygroscopic salts in the wall plaster will absorb moisture from the air giving the impression the damp course has failed. Are the gutters etc watertight? Overflowing rainwater goods will cause splashback from the ground, again bridging the damp course. These are just some of the causes of damp to ground floor walls other than rising damp. By using a qualified damp specialist you can be assured of receiving the correct diagnosis and appropriate recommendations of the ACTUAL CAUSE of the damp, not just the symptoms you can see.
