Morning
I have had a set of french doors put in where previously existed a window.
The house is about 17 years old and has a good size cavity. Trouble is the cavity appears on the inside of the house and I am not sure what to do with it.
I am having the floor tiled in a couple of weeks and the cavity needs filling with something. The tiler suggested filling with 75mm polystyrene and he would tile on top, which sound like trouble to me.
I was going to line the cavity with thick blue builders polythene and fill with concrete.
Can anyone offer any advice on the best approach, obviously I don't want to be breaching the damp proofing in anyway.
Thanks
