Even when symptoms are clear, not always can the
phenomenon be attributed to rising damp only: there can be
other moisture issues adding up to rising damp.
In particularly doubtful cases, it is recommended to have
a preliminary investigation performed by expert technicians
who can exclude other causes of dampness or give any tips
on how to solve them with specific actions.
and the molecules of underground water (liquid), and that it
is this attraction that pushes water molecules towards solid
materials.
The point seems convincing but it can actually originate poor
rising flow - a few centimetres - while those who experience
it are well aware that rising damp spreads across the wall for
many tenths of centimetres, or even metres.
For e xample, a water pipe may have broken, lateral water
infiltration may have occurred, or it could be moisture
caused by pressure (from aquifers or slopes) that are quite
usual in certain buildings.
But, there are also false or insufficient explanations. A pretty
common one is that this issue is due to a natural wear and
tear process of the masonry and plaster, which may be old,
and they just need to be replaced. This hypothesis does not
stand the analysis if you consider that problems related to
rising damp also occur in new buildings where insulation is
inappropriate or has been damaged.
Among insufficient explanations, the most common one
is that rising damp is basically connected to the so-called
“capillary action”.
Those who support this idea believe that the force keeping
water molecules together is lower than the attraction
established between the molecule inside the walls (solid)
