I have wet marks on one wall of my house had a damp company who told me the dpc needed injecting all plaster taken off and re plastered.
I showed them that previous to me buying the property someone had installed a path around the property and it was on the dpc level and not 150mm below and the pointing was damaged but he still was adamant that the dpc had failed.
I was not convinced and removed the path so now the ground is 150mm below dpc and i removed brick to inspect cavity to find bridging in many places i removed all rubbish from cavity so hope all now good.

Photo shows path now removed and i have since dug down re pointed and now have 150mm below dpc
Cavity pic shows rubble etc found in cavity i have scoped cavity and now pretty clear was full to one brick above dpc in places scope pic shows clear to bottom of cavity now

pic shows damp on wall
pic shows plaster removed

My question is i have removed the damaged plaster and plan on fixing membrane onto wall salt neutralizing brickwork and re plastering with limlite renovating plaster to allow wall to breathe. Does this sound like a good plan? probably a bit OTT but only want to do it once.

The damp expert would not of done any of the parts above only inject new dpc and replaster so would not of solved the cause!!!!
I think my Dpc is ok and have read many stories as injection is not required.

Your problem appears to relate to a bridged cavity, not rising damp. So the remedy is to remove the bridge ie clear out the cavity. Your proposed work is not required
