| I need some advice on how to separate stones and liner that have been black foamed together. I've had a significant water loss problem that I isolated to one stream. The loss is most pronounced when there is a turbulent flow of water in the stream and less pronounced with a reduced flow.
Figuring I had water loss through the rocks, in folds and over the liner, I took the stream sides and banks apart and did a major (or so I thought) foaming with black waterfall foam. You guessed it--there is still a water loss and I am literally stuck with lots of black foam in the rocks. In order to try again, I need to move rocks while dealing with the dry foam. My real concern is pulling rocks away from the liner where there is foam connecting the two surfaces. I don't want to tear the liner or puncture it with any tools. There just hasn't been time for me to explore or to start, so maybe I am too concerned? Before I do start, can anyone give me suggestions on separating foamed-together stones and liner? Thanks in advance - Mike |

| Hi, I would assume you are dealing with an 45mil edpm liner. If so you should be able to seperate it with your hands, and not hurt the liner. I definately wouldn't use any tools. Derek |

| As Derek said, I've just pulled the rocks loose from the liner with no damage to the liner. However, the rocks had been foamed in for about a year. I don't know if the length of time would make a difference. Anne |
