Hi All,
This maybe the wrong forum
I have been working on my porch and about to retile
I have removed a lot of the tiles now , and found that the bottom part of the door frame , has been held up with expanding foam
I removed the tiles and some foam , and found that the void went back past the lower door frame and reached the hall floating floor , with some rot to the end of the chipboard
Is expanding foam a suitable structural material to support an entire door and side window frame
images show the situation i'm in and propped up with blocks at the moment.
Would i be best just to fill with expanded foam again after tiling.
I will be cover the concrete in a bitumen paint, before i put the next screen down at a slope and then retile , posted about that before
My plan was to paint with bitumen to waterproof and then put a tanalised wood sealed, and painted to support the middle of the door frame onto the existing concrete floor and make waterproof and then tile up to that, leaving a gap between the bottom of the frame and tiles a which the back would be sealed and waterproof
and the wood would provide the support to the door frame onto the concrete floor, sounds to me more permanent , BUT its been like this for at least 20+years (mother-in-law was in the house since 1997 and did not change) , although because the tiles in the corner sloped towards the door and not away, filled with water, maybe its OK
clear and reinstate the drip channel which was filled with foam
But if i can just retile under the door frame and then fill with foam , that would be much easier , but would it be watertight and structural supporting the door and side windows
