Hi Im after some help with a 3ft retaining garden wall and the best method to make the soil side watertight. My intention is to have it rendered on the front and then painted, the wall is made out of 7n heavy concrete blocks. Any advice would be very much appreciated. At present the wall has been constructed but can not move forward with back filling with soil till i know which is the best and kind of cheapest method of waterproofing as i dont want the render to blow off years down the line.
Many thanks
