Sadly, on the 23rd, the river decided to pay our house a visit. Not quite the christmas i had in mind, but here we are.
it was always going to happen sooner or later, but its happened now, so the work i wanted to do has been brought forward.
Keeping it as brief as possible. Front half of house, early 1800's cottage. Brick, 9 inch wall. Back half 15 years old, conventional brick/block construction.
The front half, i already intended to remove the gypsum plaster (well ive already started prior to this) and some form of limecrete floor. (with a sump pump system of some sort)
Now is the time to make it more resilient to flooding. So lime on all the walls, as it will be coming off in every downstatirs room.
However, nice insurance peeps are saying the floors in the new part need to come up as they are screed ontop of insulation board, on top of concrete. They suspect the insulation layer not to be waterproof, so out it must come, to be replaced by waterproof version such as EPS. They pop a screed back over it and tile.
At which point i start to ask questions.
Would it not make sense to use a lime screed? So any water that gets trapped in there can, ultimately find a way out. Thoughts on this idea?
The intention is to tile the whole ground floor, so along with walls that will dry out, we can wash it out and continue living. The flooding is fast, quick, and with a submersible pump can be maintained at approx 1.5 inch depth. As the river/brook is a very small tributary to the ouse, this is what it does. Long periods of standing water are basically never going to happen. We are too far upstream.
Accepting the above, what im struggling to establish is what material the tiles, flags etc should be for the underlying lime screed to work, be it over insulation or foamed glass(front of house). I.e, it needs to be breathable. I assume i cant whach down cermaic tiles for example?
Ive also the challenge in the new part, that i cant put down anything to thick.
All thoughts welcome.
