We are needing a burm (berm?) around the edge of newly dug hole that will become the pond. To get close to the depth I've wanted in the pond it will need to be about 1-1/2 feet high. How wide does it need to be? Another question along the same line. Hubby (who is my great help in getting this done and chief hole digger, pipe gluer etc) is afraid of dirt caving in under the liner? I think there is enough pressure from the water in the pond that it is not a problem. I'm more concerned with the burm/berm being wide enough that the water doesn't push it OUT!
there pare pictures in the photobucket album under pond construction, but I find they lose all perspective of depth/size, but it may help to see.
