about a year ago we bought a house .
it has 8"solid concrete walls.recently realised there is some damp in the walls/floors .it has concrete floors.its about 80years old so slim if any chance of a damp proof course under floor.
so for the walls im thinking
chemical dpc injected into wall.been reading a bit many say they don't work because wall needs to be fully dry first and if you can do this you don't have a damp problem.
any thoughts on that one.
drylining with ventilation gap behind on inside of exterior walls and add some vents.
(exterior insulation out of our price range at moment.)
ok the floors either take them up replace with dpc,insulation and concrete again.followed by hardwood flooring.
or use this product http://www.deltamembranes.com/waterp...delta_fm_1.htm
laid directly on to existing concrete floor followed by insulation and hardwood floor.
thing is if i introduce either the dpc under or on top.am i right in thinking the moisture that would have come through the floor before will be redirected out towards the wall.making them more damp and if chemical dpc doesn't work will only be hiding and adding to the build up of damp behind the drylining.
also if i go with the concrete floor should i wait for the drying out period and use dehumidifier to get walls as dry as possible before the drylining goes on?
should i just put drains around out side of house first a see if that helps?
ok i know there is many questions here but any advice would be great or if anyone has dealt with a similar building before and has different solutions...
