RE:RE:RE:RE:RE:Apr 2022 videoThey should go to the university of Guelph and get the opinions of the phd professors that study soil sciences. They might find out that CC just might prolong the life of roads when used as a sub base. I believe if you google cellular concrete as a sub base from a study and paper done at the university of Waterloo. You will get the answer. Yes putting CC as a sub base will cost more. But in the long run the savings are probably going to be huge. The road in Yellowknife they used CC as a sub base on a two km stretch of road. It was done in 2007 I believe. Apparently they finally have to start doing repairs now. That's 15 years. Before it was an annual event.
