Rising damp is caused by water from the ground rising through joints and cracks in masonry walls of your home. The water can easily enter your home through the plaster and go back to the ground through the damp-proof course.
It is a common problem for older homes, as well as for new ones built on clay soils. Rising damp usually affects older buildings because they were not built to modern standards, but it also occurs in new houses if they are not properly constructed or if there is insufficient ventilation.
