Hi,
I know that damp queries have been done to death but I think that this one is slightly different. I have a plan but am just wondering if anyone can offer any better solution?
I have a brick constructed wall that was bare brickwork but I have recently applied dot/dab + plasterboard & skim to try and smarten it up. However, it has within a matter of weeks, started to show signs of damp up to about 400mm from the bottom. The wall is the back-side of next door's extension and is probably a bathroom or similar within. On my side, the room was a kitchen. They are old properties ~1850s and so clearly no DPC.
My plan is to cut back the plasterboard 1m from internal floor level and remove the dot/dab back to the bare brick. Coat the wall and down on to the floor with KA tanking solution and then reapply plasterboard with Instastick etc. I am having to coat the floor with the tanking solution anyway so will just carry it on up the wall.
Is 1m high enough?
Has anyone any better ideas? Seems a shame to chop off newly skimmed plasterboard.
Many thanks.
