The moisture problems in buildings are responsible for the
expenditures of millions of dollars every year. The problems that arise because
of moisture in a concrete structure are weakening, collapsing and blistering of
a structure, and cracks in the floor, ceiling and walls. The development of
mold and mildew can also surface due to excess moisture or humidity.
Sometimes humidity may advance in a building because: the required
amount of time is not given to the slab to dry up; surplus water is used in the
concrete mixture; and there is a leak in the water supply pipeline in the
building; or due to weather conditions (excess rainfall).
In many buildings, where the suggested quality and quantity of concrete
mixture is NOT used, moisture can occur right after the development is
completed.
Concrete slabs have porous and highly water-absorbent surface,
thus, there should be taken proper measures to avoid the blockage and stoppage
of water. The drainage system, the ventilation, calculated heating and air
conditioning systems should be considered to avoid the problems of humidity.
RH Moisture Testing
RH or Relative Humidity Moisture Testing is a procedure
that evaluates the level of moisture and humidity in a building. The relative
humidity probe provides the concrete testers with the most accurate information
about the slab.
RH Testing provides the real presentment of the amount of moisture
and humidity in concrete slabs, walls and ceilings. The procedure can also
state the dangerous level of moisture in a slab, which can bring about several
damages in the structure.
When
laying the floor over a concrete surface, testing the moisture condition of the
concrete as well as the ground is essential. The RH moisture in-situ probe and
meter can be helpful in this.
