Hi team,
Putting in a one acre pond that will require a dyke / dam that will be approximately 6’ high. My pond contractor will be putting in an 8 inch PVC primary drain thru the dam. His proposed method is building the dam in 4-6” lifts compacting between lifts with his thin track dozer and manually compacting around the drain pipe. He does not use seep collars in his construction.
Should I insist on a seepage control device? If so, would 1 collar, 2 collars or a sand filter diaphragm be preferable? If the sand diaphragm, what size should the sand diaphragm be?
Thanks, Tony
