Damp Proofing Question

I have a damp problem and would like to know which system is best

Our Brick built house dates to about 1894. External wall has a damp proof course about 2" above pavement level. Ground floor is about 2" above pavement too, one room stone flagged (assume no membrane) and one room concrete on top of flags (assume no membrane as nothing visible at cut-out for fireplace). Both rooms had lino flooring and appear dry now that lino is removed . Bottom of skirtings to outside wall were rotten and tide marks on wallpaper (now removed with plaster to 1m). Please advise on best system for damp proofing internal walls (eg. injection into bricks, paste into mortar,...) and floors (asphalt over flags, liquid sealing of concrete follwed by screed, slurry sealing of wall/floor transition,...).

Should I scrape out powdery mortar in the area to be injected and point it before the work is done? Also upstairs double galzed units have been installed and the plaster made good with what I have been told is Carlite Bonding. The area is damp possibly due to water getting into the cavity (the roofing felt is not overlapping the gutter - I'm in the process of getting this fixed). Should I remove all the Carlite and replaster or wait until after the felt has been fixed and see if it dries out?
