I am looking to expand my current pond (current pond is 14 feet by 24 feet roughly) and I don't want to have to rip out my current liner and rocks etc that surround my pond. Anyone have any ideas on how I can do this. My concern is attaching another liner to my current one without causing any leaks. I have looked around and I don't think gluing will work the current liner has been buried for 2 years. I need to expand again as my koi had babies and I need to make room for 70-100 of the little guys which survived the winter.
