Ozinga Coworkers Get Hands-on Training in Concrete 101 Course

At Ozinga, learning is one of our core values. We truly believe you can never know everything about our business and it’s important to seek out opportunities to increase your knowledge on a daily basis.

To that end, Ozinga recently welcomed Theron Tobolski, an instructor from the Illinois Ready Mixed Concrete Association (IRMCA), to our Mokena office for an extensive, half-day Concrete 101 course. Coworkers who don’t work in the yards on a daily basis got to learn all about concrete from a trained professional.

The training covered the basics (what concrete is made of, how to cure and seal it, etc.) as well as more advanced material (the importance of admixtures, concrete overlays, pervious concrete, etc.). Coworkers also had the chance to visit Ozinga’s Quality Control and witness a real PSI test in the lab, see firsthand how to measure slump in a real Ozinga concrete batch and learn how to check the air content.

Attendees were encouraged to ask questions throughout the training session and Tobolski quizzed the classroom on what they learned. The class was offered to Ozinga coworkers as a development opportunity to learn about a vital part of the business some are not exposed to on a regular basis.

The course helped bridge the gap between what happens in the field, and in the office, defining how roles interchange and each person’s job affects another’s. With more than 50 Ozinga coworkers taking advantage, the experience was a positive success. We hope to expand the course throughout all company regions in the future.
