How would I go about doing this. I live in an area of VERY flat land. No hillsides to cut into at all. What I have been thinking of is digging a hole inside the barn and dropping an old chest freezer in it. I am wondering how I deal with the water issue. The barn itself is dry but the entire area around it gets slightly flooded out with heavy rains. Would the under ground of the barn stay dry or do I need to put some type of pond or similar liner in the hole before the freezer. Also, how do I brace the hole to keep it from collapsing and crushing the freezer? Thanks all.
