Recently I was at a continuing education seminar and one of the speakers was a tank manufacturer. His presentation was about how good his tanks work in wet conditions because of an additive they use in their concrete. I know the speaker, he is awesome and makes great tanks. But what struck me about his presentation was slide after slide of tanks going in very deep. We are talking about excavations of what looked approximately 19 feet deep. Add groundwater to those depths and yikes.
I remember being brought in to bid on the onsite system installation for a big box
