I posted many years ago about this problem.. might have been 10yrs!!!, I never really got around to fixing it. But as now I am re-plastering / decorating inside, I really need to sort it out.
The house is 1927, solid wall construction.
My drive in block paved (by the previous owner) and slopes down towards the house, there is no drainage. In very heavy rain water can sometimes pool against the house in a couple of places. This is not helped by being on a slight hill, my neighbours drive which is flatter and 1ft above can also contribute to the water.
The DPC, I’m not sure of its location although in some places a chemical injection has been done in the past (again previous owners). The joist sit on the same level as the air brick, the floor is about halfway up the air brick. That’s a little strange because half the air brick backs on to the skirting board.
The wall inside seems to have damp above floor level, but not all the way along. The skirting board seems to have helped spread the damp. The wall has sand and cement up 1 meter, obviously from when chemical DPC has been done. Only small part of the edge of the floorboards had minor rot, one of the joist ends looks to be getting a bit soft.
I removed some of the pavers next to the house, the first course of mortar below this appears to be mostly mud. The next course lower seemed to be in better condition in the one spot I dug down so I have left that. Today I removed a lot of mud from the joints and filled that with mortar, 4:1 mix pushed right in.
So my plan is to put in a CD422 clark drains around the front and side of the house, put this where the soldier course is now against the pavers (to avoid where the gas/electric connections that come up against the house. This will leave 58mm gap from the wall, to fill this I would cut the old pavers down to that size (hiring a block cutter).
My question is, does this sound like it will solve my problems, is it a good plan?
