Penetrating damp (or Lateral Damp) is any water unintentionally coming inside from the outside through building walls. Unlike rising damp It can occur at any level from the ground up and can affect Roofs, Ceilings and Walls. Penetrating Damp is usually seen first on external walls, formed as an isolated patch of dampness that can increase in size after periods of heavy rain. This can be caused by a number of reasons including High Ground Levels, Blocked Guttering and/or damaged pointing.  Once the water  ingresses through the wall happens other identifying factors can occur.
