my dad is trying to expand a old gravel pit by building a levee farther down a valley then letting it fill up and spill over into the old pit. but he is worried that his dirt on his levee may not be good enough. i really pushed for him to get a packer but he said his track hoe would pack it good enough, now he is thinking he should have done different. So here is the question has anyone used the pond liner material in their levee? like you would when you core it by digging down below the bottom of the pond, and then putting the rubber liner running all the way around the levee. i know it will probably be expensive, but at this point he dont care. i think he just wants to be done with it
