Our newly erected greenhouse is flooding during the recent heavy and prolonged rains.Not coming in from above, but seeping up from soil.My husband dug out the base earth, layed a layer of 20mm gravel and filled in with good topsoil, but today we find it is flooded again. Greenhouse is mounted on sleepers, with soil inside and slabs making a pathway up the middle. What can we do. I haven’t started growing anything in the greenhouse as yet.
