I live in a old stone house, which is fine except for one room at one end, where a garden is about 1m above floor level on one wall. Obviously there is no dpc, the wall is, at this point, approximately 2.5 feet thick, and very not straight! Im not caring too much about cosmetics, as it has good character, but need to keep it dryer, even an improvement would be sufficient.
If i was to build a retaining wall, how would i cover the top of the cavity to prevent rain form filling the void? i also fear moving the earth around the wall, as i would not like to disturb its founds, although the wall is sturdy and shows no sign of movement.
Any ideas on the subject would be greatly appreciated!!
Many thanks, Jonny
