It did have a damp problem DPF.........and there has been a plastic membrane installed and then a floor screed (S&C).....then they have applied a liqud membrane with aggrigatte.....and I have gone over that.....

but I have to be honest..........I have no idea what "pitch" is?

all the best buddy

Pitch (resin) - Wikipedia, the free encyclopedia it was used all the time years ago when i used to screed houses , usually roofing contractors used to boil-it -up and then they applied it to the oversight concrete with an old mop-head , it looked just like your floor as they sometimes used to dash sand into it to give it key ,then a day or two later we would screed onto it ,that was the DPM !.....

Looks like they are going to carry on having a damp problem, looks to me they have plastered down to floor !

Depends how it is tanked and where the walls DPM is in relation to the floor. Looks like new plaster where skirtings have been removed

 

[Diamond Pool Finishers]

Yes i was wondering myself as i'am a qualified dam-proofing operative, did it years ago, and we were always taught to remove the plasterwork at a hight of 1M all around the room and that just guessing the scale against things in the rooms is to low, also there appears to be salts comming -out on the walls where its not been taken off properly ( trouble there already ) the reason you remove 1m high is because rising damp can never go any higher that 1m ,so you always assume that its infected to that hight !!!...........

It is new plaster, but still plastered to the floor.
And to b fair ajax if the dpm is below the floor, its wrong mate . Never bridge a damp course, i honestly thought it was a no no in plastering( unless upstairs) plastering to the floor, especially in a damp climate like ours !

good point dave!
at least they have carried the dpm to dpc level..i used to do loads of floor rip outs with quarry tiles and put down plastic membrane with the new screed on top and one of the big faults was when lads didnt cut into the mortar above the dpc level and tuck in the membrane and seal with a mastic. if you didnt do that they the damp would just come up the side and into the walls.

on another note, lee (protiler) has done a good job of the slc! shame some other tiler is going to to tile it.

no one else will tile it ED.....I did a screeding job for a leading London wood flooring company, plus there is no plasterboard in this apartment....its a basement flat and all the walls are brick, render and plaster.......

I don't disagree ... Was just making a point. Only time I plaster to the floor is upstairs...even then I don't usually cos the skirtings cover the gap.

We used to plaster when a sand/cement screed was going to be laid and keep the gypsum plaster above where the level of the screed was going.

Any tanking/damp issues the render would be taken up a metre high from the floor with a intagral water proofer.
