Hi
i have a 1950's semi detached pebble dash. the perimeter walls have DCP, but the concrete floor has no damp proofing and i believe, neither does the party wall
currently the floor reads damp with damp detector and small white crystals form on the joints of old insulation tiles presumably where damp dries out and evaporates
would like to damp proof the floor without having to dig it up.
i've read about paint on products (e.g. 'Aquaseal') to tank out the floor or to lay DPC polythene products as alternative options
i've also read its important to tank up to the DPC on the walls otherwise the damp from the floor which can no longer evaporate is forced up the walls.
but if the party wall - (or other internal walls) don't have a DPC, i presume some kind of barrier would be needed between the floor and the party wall to prevent damp creeping up the party wall?
could anyone advise if this is correct? and if it is offer any solutions on how to create the barrier?
Thanks
Bex
