Pond Boss Forums POND CONSTRUCTION Building a dam Filter Diaphragm in lieu of Anti-Seep Collars

Ed: You mentioned additional costs. Is it generally much more expensive than anti-seep collars?

Ed & Mike: Which option would you recommend? (my situation is a mostly clay soil type in the midwest with a pond of 2 - 3 acres and small enough watershed that I doubt pond would ever overflow)

Thanks!

Jeff
