Damp
in Buildings
If damp is present in a buildings it can result in moulds
and fungi growing and
damaging the interior and exterior decor, causing wood
rot, and ultimately damage to
the structure of the building. Damp is usually
caused by one or more of the following:
Condensation
Rising
Damp
Water Ingress

Condensation; Poor insulation, poor ventilation, overcrowded
accommodation,
and poor control of water vapour generation can all contribute to
condensation.
Properties that may have been vacant for long periods of time are also
prone
to this condition. | | -

Rising damp; Most buildings are porous and have tha capacity to absorb moisture
,
however when it is built in contact with the ground, the soil, which has a normally
high
moisture content will cause it to become wet. The drying effect of the air will
result in the taking a wick persona. The water will move up the wall and evaporate
from the surface. The height the water will reach is dependant on the walls
factors,
i.e, wall thickness, materials used in construction etc. | | -
More on Rising Damp.......... | 3.
Water Ingress; Water that enters a building from above the DPC is when water
ingress
occurs A faulty roof, defects in the brickwork and plumbing could all
contribute.
Where rising damp affect the building up to approx 4’ from ground level,
water ingress tends to affect the upper parts of a building . Elimating the
problem
can be simple and inexpensive however it is best to catch it early
to elimate high costs. | | -
