Hi this is preying on my mind and so i wanted to ask for opinions before i put tiles down. Its been a lot of work but we've finally finished removing the concrete part of my kitchen floor and putting in a properly levelled suspended floor throughout. As you can see from the pictures i've used PIR boards to insulate the floor with a layer of membrane between them and the current surface, which is made up of two layers of 12mm ply wood glued together and screwed down. Since i was using PIR i thought it unnecessary to staple the membrane below the insulation.
My anxiety is about what would happen if there was a major spill of liquids on the kitchen floor once its tiled. Would the water collect on the membrane directly under the ply, be unable to escape and rot the whole floor? Is there anything i should do before it is tiled to avoid a future problem like this? I can't take the ply up as its glued down now but could maybe put drill holes in to give any internal liquids a chance to escape? Once its tiled the tiles will in theory be waterpoof in any case.
Its worth saying that around all the walls i have brought the green membrane a couple of inches up and sealed it to all the walls. Around half of the walls have been damp proofed now so the idea being that any damp from behind the walls will drain down the side and sink into the soil under the floor. This part feels bullet proof to me but in doing that i've kind of installed a huge waterpoof saucer under my ply. Is this a normal thing to do? Is it a good thing to do? I picked it up off a youtube video where the guy had also membraned his floor with a single sheet of plastic.
Any thoughts appreciated.
