Introductory Exam Review
The ICRI CSMT program is distinctive because it strictly evaluates your understanding of four critical ASTM standards required for concrete moisture testing. Earning this certification protects contractors and facility owners from catastrophic flooring failures. Preparation is crucial, as the exam requires exact knowledge of testing environments, equipment limitations, and proper reporting procedures. Utilizing high-quality practice tools bridges the gap between field experience and textbook ASTM requirements.
Practice Test Modules
Concrete Moisture Fundamentals
This module covers the basic science of how concrete absorbs, retains, and releases moisture. You will review capillary action, vapor drive, and the physical properties of concrete mixtures. Understanding these concepts is essential for accurately interpreting moisture test results in the field. Start Free Test →
Test Method ASTM F2170
Master the in situ relative humidity (RH) testing procedures. This section tests your knowledge of drilling depths, hole preparation, equilibration times, and reading electronic hygrometers. This is one of the most heavily tested subjects on the exam. Start Free Test →
Test Method ASTM F1869
Review the protocols for measuring the moisture vapor emission rate (MVER) using anhydrous calcium chloride. You will be tested on site preparation, dome placement, weigh-in procedures, and the specific calculation formulas required by this standard. Start Free Test →
Test Method ASTM F710
Learn the requirements for preparing concrete floors to receive resilient flooring. This module dives into surface cleanliness, pH testing protocols, and the visual inspections required before applying adhesives. Start Free Test →
Site Preparation Requirements
Understand the critical environmental conditions necessary before testing begins. You will review the required temperature and humidity ranges, HVAC operation timelines, and how to verify that a building is ready for official moisture testing. Start Free Test →
pH Testing Procedures
Alkalinity can destroy flooring adhesives just as quickly as moisture. This section covers proper pH testing techniques, including surface preparation, the use of distilled water, and how to properly read pH paper or digital meters. Start Free Test →
Equipment Calibration
Sensors and scales must be highly accurate. This module evaluates your understanding of factory calibration limits, field verification checks, and how to maintain the integrity of your testing equipment over time. Start Free Test →
Environmental Tracking
Ambient conditions dramatically affect concrete moisture readings. You will practice measuring and recording ambient temperature, relative humidity, and dew point, ensuring all variables are tracked according to ASTM specifications. Start Free Test →
Troubleshooting Common Errors
Identify the most frequent mistakes technicians make in the field. This section tests your ability to spot compromised testing locations, faulty equipment readings, and deviations from required equilibration timelines. Start Free Test →
Report Generation and Documentation
Data is only useful if it is properly documented. This module covers the mandatory information that must be included in an official moisture testing report, ensuring legal and technical compliance for your clients. Start Free Test →
ICRI Flashcards and Exam Questions
Question: According to ASTM F2170, how long must the test hole equilibrate before taking an official relative humidity reading? Answer and Explanation: 24 hours. Once the hole is drilled, cleaned, and the sensor (or liner) is inserted and sealed, the environment inside the hole must equilibrate for exactly 24 hours before a recordable measurement can be taken. Practice with Flashcards →
Question: What is the correct drilling depth for an in situ RH test on a concrete slab drying from one side only? Answer and Explanation: 40% of the slab thickness. ASTM F2170 specifies that for slabs drying from the top only (such as on-grade slabs with a vapor retarder below), the hole must be drilled to 40% of the total slab thickness. Start the Free Practice Test →
Question: Under ASTM F1869, what is the required area of the test site for a calcium chloride test? Answer and Explanation: 20 inches by 20 inches. The concrete surface must be cleaned to a bare finish over a 20x20 inch area to ensure proper adhesion and sealing of the plastic dome. Access Study Guides →
Question: What is the minimum time a building's HVAC system must be operating at service conditions before moisture testing can begin? Answer and Explanation: 48 hours. Both ASTM F2170 and F1869 require the testing environment to be at service temperature and humidity for a minimum of 48 hours prior to the start of testing. Practice with Flashcards →
Comprehensive ICRI Study Guide
Basics | Format | Registration | Results | Study Tips
Exam Overview
The ICRI CSMT certification includes both a written examination and a performance assessment. The written exam evaluates your theoretical knowledge of concrete moisture behavior and strict adherence to ASTM standards. You must pass the written portion to prove you understand the science and rules before demonstrating your physical skills.
Exam Administrator
The International Concrete Repair Institute (ICRI) develops and administers the exam. They aim to elevate the quality of concrete restoration and flooring installations by ensuring technicians use scientifically sound, standardized testing methods.
Reasons to Take the Exam
Holding this certification instantly validates your expertise to general contractors, architects, and flooring manufacturers. Many project specifications now strictly mandate that only ICRI-certified technicians perform moisture testing, meaning this credential directly unlocks new business opportunities and minimizes liability.
Navigating ASTM F2170 Complexities
Many candidates struggle with the specific equilibration timelines and depth calculations required by ASTM F2170. Do not rely solely on field experience, as real-world shortcuts often violate standard testing rules. To master this topic, create a timeline chart that maps out the exact hourly requirements from HVAC activation to final sensor reading. Memorize the 40% (one-sided drying) and 20% (two-sided drying) depth rules, as these are virtually guaranteed to appear on the exam.
