| Thanks Kent. That all makes sense to me. I'm kicking around options for the next pond and was thinking about block & plaster mainly because it's something I can easily do myself. One thing I'm not surea bout Lukes product is how crystals grow in leaks. Most substances crystalize as they dry out and dissolve in the presence of an active leak.
Do you ever use Sanitread?
I think I would use plaster before I sprayed Butches poly on sheets of Geotextile on dirt, or 50 mil on block. I'm sure the stuff works ok, but I have doubts on the cost of a good application. |
