I got in a builder in to lay a patio and put in a raised flowerbed. The flowerbed sits in the corner of the patio adjacent to a wooden fence and the house. I'm concerned about drainage (there isn't any - he claimed this wasn't included within the quote). All he has done is put in a 90 degree wall. That means there would be no barrier between the soil and the fence/house wall so obviously going to cause damp issues etc. I realise this isn't the best location for a flowerbed but can anybody suggest something to prevent water/damp seeping into the fence/house?
Any thoughts would be much appreciated.
