Pond Boss Forums POND CONSTRUCTION Building a dam The Saga Continues

Bill my thought is that the water will travel down the liner (like a crack in a rock) as there is no bonding between the liner and the soil.

BTW I had to double core with a second core once on a pond and learned a lesson. In my case the second core was not as high as the water level of the pond. The water made a soft / leaky area between the 2 cores. I went back and increased the second core height to the 1st cores height. Has a dam big enough for a 2 lane road when finished. LOL
