I though this may be an interesting topic for people to think about and i have not seen much on the web about it.
Here go's:
Instead of having a chemically injected DPC and installing a DPM to the ground floor of my old house (built 1910ish) I decided to strip off all the lime render (that was literally falling off some walls due to years of condensation and a slight bit of rising damp from the previous owner) and then render the bottom meter of the wall using a sand cement render.
I then painted the render to the bottom 1m of the walls and the existing floor slab with several coats of bitumen emulsion ensuring good coverage at the wall floor joint.
I then laid a 50mm concrete floor screed over the bitumen and then dotted and dabbed the walls and then skimmed them. It looks so much better now.
Within a week the room felt dryer and warmer.
Has anyone else used this system it was so cheap to do. it literally cost me about £100 in materials (including tools) and 5 days of work for a room about 3.5 x 4 m.
I honestly think that installing a DPC to an old property can be a waste of money when systems like this are so much cheaper to install.
Some will say its a no brainer installing a chemical dpc if your re plastering anyway, but this method i used saved so much money and it was all work i could do myself.
Anyone else tried this out, i would be interested to hear from anyone who did this a few years ago to see how their room is holding out?
I plan on using this method for the dining room and kitchen which are on my list of refurb works for the rest of the year.
