I have been looking into using Quikrete Rip Rap to line the edge of my pond instead of limestone or broken concrete. I'm looking for tips from anyone who has used it for this purpose. Has it worked out well? Did you go one or two bags wide? Also it seems to be quite a bit more expensive than the standard bag of Quikrete. Is there any reason to use the "Rip Rap" product instead of the regular bag of cement?
