What to do about flagstone?
I plan on putting several cources of flagstone in and around my pond,
the question that I have is , should I cement in the first cource with type 1-a concrete or not? I was planning on doing this for the rest of the layers but I'm not sure about the rest? Any advice out there? |

What to do about flagstone?
You can mortar them to the liner and to each other. I would use mortar
since it is made with sand, where concrete has rocks in it that makes the minimum thickness nearly 1 inch. Try to keep any of it out of the pond while you are working. It is very alkaline, with a pH of about 13. If you can keep it above water level, then it should not cause any problems, but if it is below water level, the lime that is one of the byproducts of the chemical reaction, will continue to leach into the pond, causing high pH values. It really needs to cure for several weeks and be allowed to air dry before submerging in pond water to limit the leaching of the lime. -- RichToyBox http://www.geocities.com/richtoybox/pondintro.html "Black Knight" wrote in message ...
