We have dug up 120ft X 65ft X 15ft farm pond and considering going for a permanent structure rather than using the sheets. We have a separate farm pond with the sheet and we use it as operating farm pond (inflows and outflows). The new one is more of reservoir and will only be used in those must use situations and given this we thought going concrete is a safe bet.
our thinking is going with concrete bed on the bottom and the side walls will be built using cement bricks (with metal/crushed small stones) and then plastering the insides of the wall. We will fill in the minor gap between the walls and mud with concrete. have been told that it is possible the concrete walls will develop cracks and there could be water seepage. I would like prevent this issue if possible.
are you aware of anyone building large farm ponds with concrete walls and any issues with them? any ideas to prevent cracks?
