I have already posted this in the garden section but building might be more appropriate.
My daughter lives in a flat area with a high water table level, on visiting her last September she had dug a rectangular hole in the garden 2ft deep, at first I thought she was excavating for a swimming pool only to learn it was for a sunken patio and she had given no thought of water from above or below. By Xmas she had a pond, this has now subsided due to the very dry weather.
Obviously decent footings and a retaining wall needs to be built with dpm and shingle behind with drainage outlets in the first course of bricks, my dilemma is what to do with the patio base? I am thinking of laying a dpm covered with 4" shingle to allow any water to drain to a sump pump. Has any one any suggestions please other than filling the hole in again.
