There is evidence that my property was damp proofed sometime in the past because you can see injection holes. But I still have areas of dampness inside at the foot of the walls. Can you explain this ?

There could be a number of reasons for continuing dampness - failure of the injected dpc, continuing bridging of the dpc eg because a plinth render has not been removed or part of the wall inside being below ground level and requiring the application of a waterproofing slurry coating. However the most common fault is in the replastering either because a lightweight plaster has been used instead of a sand and cement render with salt retardant additive or secondly where the new plaster has not been stopped short of the floor and so is bridging the new dpc
