How to Write A Good Concrete Moisture Testing Specification

1
How to Write A Good Concrete Moisture Testing
Specification

• EP Floors Corp.

2
Type of testing to be done

• ASTM F 1869 moisture test
• ASTM F 2170 moisture test
• Add pH testing per ASTM F 710 if indicated.

3
Number of tests

• The standard calls for three tests for the first
  1,000 sq feet and one test
• for each 1,000 sq feet thereafter. However, this
  number may change,
• depending on the size of the slab, age of
  concrete, building temperature
• and RH, and the preliminary results from the
  Static Moisture Testing.

4
Timing of testing

• The temperature and humidity conditions are
  important for the
• dynamic test (Calcium Chloride). For new
  construction, dynamic
• testing should be done after the building is
  enclosed and the
• HVAC system is running, and the areas have
  reached steady
• state conditions. 

5
Reporting

• Test reports should contain the conditions at the
  time of testing,
• methodology of testing and test results. This is
  an important way to
• document not only the test results but the
  accuracy of the testing that was
• done. The specification should also identify who
  is to receive the report
• the owner, general contractor, architect or all
  parties.

6
Mapping

• The more sophisticated reporting done will show a
  floor plan
• with the test results, which can help the
  construction team
• identify problem areas in the floor.

7
Repair options

• The report should include options for repairing
• a floor that exceeds the manufacturers limits.

8
Moisture Testing Specification

• The moisture testing specification may be
  standalone specification as
• part of a concrete floor slab section that
  details some of the key points of
• a concrete industry standard designed to prevent
  floor covering moisture
• problems.
• The details may include the need for
• The concrete to be dry, clean, smooth, and free
  of contamination.
• Concrete should be moist cured for at least seven
  days (failure to do so may increase permeability
  four times or more)
• The installation of a vapor retarder directly
  under slabs on or below grade.
• The use of moisture-retaining coverings for
  curing concrete.
