Where can you source battens that will not be rotten in 10 yrs time, for dry lining?
All the fencing threads are full of accounts of treated posts failing after a few years.

For a damp proof sheet google oldroyd membrane. Thick plastic with dimples to prevent capillary action drawing water up.
Special foam plugs fir fastening to wall.

We have a conversion to do in a shed with solid walls that are always damp, the best system appears to be what you have said or similar.
Unless anyone wants to say otherwise.
Seems to me it is better to use this type of system to allow any water to drain out under the floor than to seal the damp in with renders or black stuff etc.
The 4x2 wall studs can then be fixed top and bottom, not in contact with any damp or making any cold bridges by fixing to outer walls

Oldroyd is good if you're re-doing the floor and can put the wall membrane behind the floor visqueen to get the water away and down.

Thanks for the picture, looks kind of how I thought it would work.
I assume that the Oldroyd goes down to below the concrete floor slab?

why don't you treat the wall out side as long as its not rising damp you can water proof the out said of the property, easily done
Please private massage me some photos and your location so I can google maps you as I'm from Cornwall were this is a problem on most granite house. I do lots of this type of treatment locally
Kind regards

Some truths but what to do with all that moisture eh? Condensation then becomes the biggest issue.
Try living in a B or A rated property. There is a constant battle with condensation and any cold surface is your enemy.

Recipe for disaster. Your first task should be to ask yourself why the wall is damp in the first place.
Answer tends to be a Non Cavity wall with no DPC….
Solutions are available…but a stud wall stood off the existing with a moisture barrier on the back and good insulation is the answer.
Belt and braces would include an air brick top and bottom of the existing…but probably not needed.

Has anyone mentioned lowering the water table overall?

What made the biggest difference here to a house that literally used to flood was deepening the open ditches right back to the lowest discharge (on flat ground). Literally deepened the ditches back at least 300m to discharge point on neighbouring ground, so the bottom of the ditch is dead flat. At one point, the contractor dug out a blocked culvert -- then found another blocked culvert below that showing how far out of level the drains were! The whole farm is dryer now. Check that before you do anything.

I have seen contractors putting in french drains around a house to lower the water table by the walls
