My friend's heart attack really set him back and set this project back by over a year. Then it took more convincing that it wouldn't be that hard or expensive to get people interested once we had testing done.
He has specialized in corporate take overs in his business career and has been the president and ceo of several companies that he either merged with others or sold off divisions and has made quite a huge bankroll doing it. This will be the first time he has ever taken on a project from start up and he was reluctant in that.
But his wife and the wife of president of the 5th largest concrete company in the US are best friends and at dinner party he mentioned it to the president of the concrete company . When he told the guy about it and the price per yard his reply was, "if you can do it for that price and it works bring me the results of the tests. You are sitting on a gold mine." That has stoked his fire to say the least. Hopefully all goes well with this next round of testing and things will take off shortly after those tests.
As wet as it is where you live I am pretty sure it would sell well down there.
