Mould has roots that penetrates different constructions- Air, damp
and nutrition is the most important prerequisite. Sometimes moisture
content as low as 40 -60% is enough for multiplication and growth.
Many sorts produce hundreds of toxins -mycotoxins- and there are many
very dangerous sorts of mould and fungus. There can be toxins even if
no spores are found.
Many of them cause serious illnesses -asthma, dry cough, and pneumonia,
problems in upper respiratory organs, sinusitis, skin rash, disorientation
and nose-bleeds.
Many species are poisonous and several mycotoxins are carcinogenic.
Heavy exposure can lead to considerably more dangerous illnesses.
If the space is damp -and side walls in crawl spaces are wet or damp
-then this can be a pre-stage for future damages.
Visible damp can be a consequence of water from outside that has seeped
in under the side walls.
It can even be caused by condensate on ground walls and under the joint
system.
Visible damp exists within older crawl spaces. Many times damp protection
is missing on the outside and the system of joints have been tightened
-with decreased temperature and condensate as a consequence.
If there are discolouring or visible affections by mould under the
system of joints, this is a sign of the foundation is to damp.
The microbic growth is considerably more common in joint systems in
new houses. This is because most of the construction material in the
joint system is different to that in older houses.
If a microbic smell -as an earth cellar or of mould- is detected in
the joint system, the cause should be examined. The damage is a fact
and actions must be taken.
This is due to the relative moisture content is so high -during parts
of the year- that growth of micro organisms can start.
These organisms create smells over time. Regardless if it the smells
come from the ground or the joint system, the source of this must be
examined and actions must be taken, else there is an imminent risk of
the smell getting into the living area.
The number of rot damages is larger in older houses because the rot
fungus normally takes longer time to develop than a mould fungus.
When a joint system has changing moisture content depending on the time
of year, the development of a rot fungus takes long time.
Normally it is during the late summer and the autumn the rot fungus
have sufficient moisture to grow. For the rest of the year they are
hibernating.
The combination of several causes increases with the building's age.This
is expected, since the damages are getting worse over time.
One example is when it begins with damp that leads to microbic growth.
If it is adequate damp during long time it ends with rot damage.
