ICRI Concrete Slab Moisture Testing Technician Grade 1 Status: Achieved

At the end of January, I traveled to the World of Concrete Convention in Las Vegas to acquire certification for Moisture testing.

Years ago, I used to go the convention on a regular basis. It is always fun to go and see the latest innovations. I usually get a few promising ideas to bring back and apply to our operations. Everything from software innovations…. to kits to convert wheel barrows into vacuums and everything in between. I haven’t been in a few years because there are usually more relevant conventions for our business. For example, there will be a convention in Omaha in April where our entire management team will attend to receive training on each of their areas of expertise.

The main reason for going was to take classes and exams to achieve the certification in concrete moisture testing. I did this for several reasons. Moisture vapor emissions is pervasive problem. It is a billion-dollar problem in the US alone. A simple Google search pulls up many articles. These articles acknowledge the severity of the problem. Roughly half are from the resilient flooring experts who are pointing out the emission vapor rates that are required to achieve success with resilient flooring or epoxy coatings. The other half are from concrete experts who are expounding the difficulties in achieving those rates. What I don’t find is any consensus on achievable solutions.

I am very interested in this because our Patented MoistureLevel® system is a novel, cost effective solution to this pervasive problem. Much of the moisture emission comes from the concrete as it holds onto original moisture until air conditioning starts to pull it out. Much of the moisture comes from the soil below the concrete. More a more in depth discussion on mechanisms of moisture accumulation in a slab on grade see my earlier post http://www.foundationaz.com/proper-investigations/Why-moisture-accumulates-under-a-slab-and-does-not-dissipate-over-time.html

Most of the solutions for this problem involve applying sealers to the top of the existing concrete. This has not been a largely cost effective solutions nor a particularly successful one. For more on this subject see my earlier post http://www.foundationaz.com/Vapor-transmission.html .

I decided to become more familiar with this industry its solutions and methods. I did take the classes and I did pass both written and demonstration exams. (I was later informed that the pass rate was around 50%). I learned the different tools for measuring moisture in slabs, their relative strengths and weaknesses and how to use them properly.

Having better information on a particular slab, where it has more or less vapor emission rates, we can design better, more effective air paths below a slab to alleviate the problem.
