"Rising damp" on walls is caused by ground water moving up through a wall. Most walls allow some water in, but it's usually stopped from causing damage by a barrier called a DPC - Damp Proof Course. DPC is usually a horizontal plastic or slate in the wall.
If DPC is missing or ineffectual, your wall may suffer from rising damp. This type of damp can also happen when the level of the ground outside your home is higher than your DPC, allowing water to get above it.
If you have Rising Damp you may notice damaged skirting boards and floorboards, crumbling or salt stained plaster and peeling paint and wallpaper. There may also be a tide marks along the wall.

Plaster, bricks, mortar joints, decoration and wall coverings can be similarly seriously affected by the growth of dry rot fungus or associated moulds which start and then thrive in wet conditions. Without the presence of water, timber timber decaying fungi cannot develop.
It is vital to be able to recognize the differences between the four main causes of structural dampness:
