Hi,
I have built a workshop in my garden, concrete block base with a timber framed upper. The structure is built up against an existing block built garden wall. Before building my workshop I repaired this existing wall on the inside (my side) but have not done any work on the opposite side.
The wall is the weather facing wall and is letting damp through. Initially I thought the water was coming in were it was seeping in between the wall plate and the wall but after covering this up with plastic it continued so I can only assume that the driving water is simply seeping through the wall.
What would the best course of action be to waterproof this wall after of course fixing all defects / pointing.
1. Should I render the wall with sharp sand / cement and plasticiser?
2. Do I need to paint the render to waterproof it further?
Here is the wall in question from the inside, the dark patches are damp.
Thanks for your advice
