NATIONAL FLOOR COVERING ASSOCIATION

"It's not dry just because it's old"
R

ecently our inspection service, the NFCA Quality Assurance
Program (QAP), was specified onto a medium sized, commercial
building expansion in the lower mainland, BC. The building
in question was a retail outlet built approximately 40 years ago on
concrete slab. The new floor covering was to be a resilient floor tile.
To start the QAP inspection service, all parties were invited to
attend the pre-installation site meeting as per spec. Among the many
items on the agenda were 'acceptable site conditions' required by the
manufacturer which include ambient site temperature, slab temperature, relative humidity, floor flatness, on site storage/acclimation
and moisture testing requirements.
By the end of the meeting all agenda items had been explained and
agreed upon with the GC (General Contractor), accept for the issue of
moisture testing which he had objected to as he thought that testing
a 40 year old slab was unnecessary and a waste of time and money.
Note: In this case, testing to the floor manufacturers specifications required using the Anhydrous Calcium Chloride test method
as detailed in ASTM F-1869. This standard requires three tests for
the first 1000 square feet and one test for each 1000 square feet
thereafter. So, with 30,000 square feet of floor area to do, 32 individual tests would be needed to satisfy the manufacturers' moisture testing requirements.
The inspector explained that moisture testing was required by the
manufacturer for warranty purposes and that the NFCA specifications
also required that the GC provide and pay for a third party to take the
tests. The GC continued to object at which point the building owner

got involved making it clear that they wanted the floor installed with
a warranty and that the GC would comply with the specifications.
The meeting ended.
One week later the tests results were provided to our floor inspector
by the GC indicating that all tests at the north end of the building had
failed with an average MVER (Moisture Vapour Emission Rate) of
9lbs instead of the required maximum of 3lbs. It was determined that
the water table (possible underground stream) was raising moisture
levels in that area of the slab.
In light of this information the building owner approved a moisture
barrier, which was promptly applied and the job moved forward with
warranty intact.
