The International Concrete Repair Institute (ICRI) has announced 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 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, and a written exam. 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. They can also be added to the ICRI Certified Slab Moisture Technician database if desired. 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, is valid for a period of five years from the date of completion of all applicable certification requirements. ICRI plans to hold the Slab Moisture Testing Technician Certification programs in Chicago, April 9 & 10 and in Baltimore, October 1 & 2, 2014. Details, including the application and registration forms, are available on the ICRI web site at
