MOISTURE TESTING GUIDELINES
When performing moisture testing of concrete it is
important to get the most accurate and most useful
data from the tests. For this reason Tramex recommend
a two-pronged approach.
• The first step is to carry out a non-invasive
moisture test with the Tramex CME5 or Concrete
Moisture Encounter X5. This measures the top
section of the concrete slab and gives an average
percentage moisture content of the footprint area
of the meter. These readings should be used to
determine where and how in-situ relative humidity
(RH) testing is performed.
• For in-situ RH testing, Tramex recommends that
the test holes are drilled, sleeves are placed and
capped and left for a period of 24 hours. The
probes are then inserted. A suitable equilibration
time is allowed before taking readings (see below)
• Tramex recommend that the RH probes are not
left in-situ for prolonged periods of time when RH
values are above 93%. With the Tramex system it
is possible to remove the probe and seal the sleeve
for future testing, thus giving a more reliable and
accurate test.
• The above recommendations are based on the
requirements to prolong the life of the RH probe
and to increase the accuracy of the test.
