OK fellas, I need some advice. I am in the process of trying to repair an embankment dam for approximately a 2 acre pond. I do not know what the original dam materials consist of, and whether or not the dam was core trenched. Five years ago a contractor dredged the deep end of the pond with a drag line. That was a BIG MISTAKE. The pond is now dry. Our plan is to patch the compromised bottom with a clay mixture, and construct a blanket core on the backside of the dam, core trenched into the existing clay subsoil. Has anyone had successful results using a blanket core on the backside of an existing dam? We would like to keep the existing dam in place to lower construction costs. A blanket core on the inside (water side) of the dam was not considered because we do not want to lose water volume. Any suggestions would be greatly appreciated.
