The shelves were cut in to a clay/sand mix. Mostly clay (probably 60% clay)they call it red dog here, its a real red clay. The only reason I think it might be seeping there is that it seems to be stable until it gets over the first shelf. Everyone else tells me not to worry about it yet like Rainman said. I find it hard not to worry about it though

obsession would probably be a good term . We are suppose to get a few inches of rain today so well see what happens. Rainman I'm about an hour from you if you ever want to take a road trip and give some advice on what to do next. Thanks everybody. Keep you posted. Oh and the hydrated lime was in an earlier post where someone said this old farmer told them he had used it to fix leaks for years but no one could substantiate this.
