Over nearly two decades of research, I have uncovered a lot of interesting information regarding concrete corrosion due to microbially induced concrete corrosion. Recently, I presented my research in the form of a FREE webinar for the Wastewater Education Association. The link to the recorded presentation is:

This presentation is a product of research that includes dozens of research papers on this subject that dates back to C.D. Parker in the 1950's. There is still a lot we don't know about this condition that affects sewage conveyance systems around the world. It is important to note that a relatively small amount of area geographically seems to be prone to this issue, so if you don't see this in your area, there is very little cause for concern.
For more information on this condition, email me at precastguru@gmail.com. Use the phrase "MIC question" in the subject line. I look forward to your comments and questions.
In this series of blogs, the author will examine the causes of biogenic concrete corrosion and offer some explainations for how this occurs. The purpose of the information is to highlight the fact that this does not occur to all concrete products, that quality practices and mix designs are an important element in the prevention of it, and that there are some additional technologies on the market now that combat the cause of biogenic concrete corrosion.
