We've been planning a pond for a while now, plan is 2ft below ground and 2ft above. After doing some research we decided to build it with concrete blocks. Now we haven't brought the blocks yet, we've just finished the planning really but my other half has come home tonight and said that a pond built with concrete blocks is liable to the walls collapsing! apparantly someone has told him that concrete blocks are not to be used for a pond.. now i am confused!
anybody got any suggestions about the concrete blocks?!?!
