The International Concrete Repair Institute (ICRI) announces the dates and locations for the association’s successful Certification program – the Slab Moisture Testing Technician Certification, Grade I. The purpose of this program is to help improve the performance of concrete slab moisture testing in the U.S. to result in more consistent, accurate results that will help flooring manufacturers, architects, and contractors to make better decisions as to when a concrete floor is ready for a floor covering installation.

The ICRI Slab Moisture Testing Technician Certification program has 2 tiers. Those interested in attending both Tier 1 and Tier 2 must complete a registration form and an application. Tier 1 applicants are those who are not regularly engaged in moisture testing, yet have an active interest in learning more about the tests, what the tests mean, and how the tests should be performed. Tier 1 consists of a 3-hour educational session, a written exam, and a training session. Those who complete Tier 1 and pass the exam will be issued an ICRI Letter of Achievement.

Tier 2 applicants are those who have applied for full certification. Tier 2 consists of the same 3-hour educational session, and written exam, but also includes a field testing performance exam. By passing both the written and field testing performance exams, a Slab Moisture Testing Technician, Grade I certification will be issued by ICRI to those who successfully demonstrate the knowledge and ability to properly perform and record the results of each of the four field moisture tests on hardened concrete. Those who pass both the written and field testing performance exams will receive a certificate and a wallet registration card. Prequalification for acceptance into full certification Tier 2 will be previous testing experience.

Both the written exam and the field testing performance exams will be based on the following four (4) ASTM Standards, including all Annexes and Appendices:

  • F 710 Preparing Concrete Floors to Receive Resilient Flooring; Section 5.3 pH Testing.
  • F 1869 Measuring Moisture Vapor Emission Rate of Concrete Subfloor Using Anhydrous Calcium Chloride
  • F 2170 Determining Relative Humidity in Concrete Floor Slabs Using in situ Probes
  • F 2420 Determining Relative Humidity on the Surface of Concrete Floor Slabs Using Relative Humidity Probe Measurement and Insulated Hood

ICRI Slab Moisture Testing Technician Certification, Grade I, shall be valid for a period of five [5] years from the date of completion of all applicable certification requirements.

The class will begin on the first day with registration from 8:00-9:00 a.m., followed by the 3-hour educational session. There will be a provided lunch and a study break from 12:00-1:00 p.m. followed by the written exam from 1:00-2:00 p.m. Following the written exam, Tier 1 applicants will attend a training session where they may receive or observe hands-on training on how to properly perform each of the four field performance tests.

For those registered for the full Tier 2 certification program, day two begins at 8:00 a.m., and each applicant will be required to perform all four ASTM tests listed above.
