Hi there this is my first post. I have read and learned a lot through this great site, many thanks!
We are in the process of renovating a turn of the century burstone house in the Paris region. Around 1940 the local council unfortunately decided to build a huge "extension" onto the house down to basement level, to turn the whole thing into a hospital. The seller of the house demolished 6 meters of the adjoining extension before we bought and renovated the house.
I wanted to protect the basement wall with an impermeable morter, butumin and a drainage composite (Delta Drain, Doerken) plus put a drain in.
Unfortunately the demolishon left a lot to be desired. The extension affected the entire north face and enveloped the north west corner and continued half the length of the west face of the house.
However when I dug down I realised that they had only demolished above ground and that the entire tiled floor of the basement and conservatory (sloping ground above means conservatory was at basement level) of the extension are still intact and butt right up to the external basement wall of the house!
Well I removed the tiled floor in the bottom of the trench that I dug at the footing so I could get down below basment floor level to put my drain in. However the rest of the tiled floor remains buried under earth and will obviously prevent water draining through it!
Sorry for the long thread, we're nearly there...
My question is can I leave things as they are with my drain placed just below the level of this tiled floor (which is about 15 or 20 cm below the level of the internal basement floor) or should I put a sort of "levvy" of ciment on the edge of it to stop the water being channelled into the area next to the basement wall?
Many thanks for your help!

Nope we're in the middle of trying to move into the house and the staircases are not even fitted yet! I'll get back soon, but thank you very much for your presence, much appreciated. I'll try to get the Brownie out today!
